How does visual photography record video?

Hello, the steps of visual photography video recording are as follows:

1. First of all, you need to prepare the camera to ensure that the camera has enough batteries and enough storage space.

2. Then, you need to determine the shooting scene and adjust the camera settings to get the best shooting effect.

3. You can start shooting next, remember to grasp the time and avoid shooting for too long.

4. After shooting, you can export the video file to the computer, and edit and post-process it to get the best video effect.

Finally, you can upload the video to the network or save it on your hard disk for later viewing.

I hope the above content can help you record high-quality videos easily!

How do digital cameras shoot videos?

Take how Canon EOS7D digital camera shoots video as an example.

The method is as follows:

1. Step 1: Select the appropriate gear. Some SLR cameras have a special shooting gear, and there is a camera gear next to the gear. If there is no gear, you can choose M gear to shoot again, as shown below.

2. Step 2: Switch to shooting mode. After selecting the gear, you need to switch your shooting mode to video mode in the shooting mode near the viewfinder, and twist it to the left to enter our shooting mode, as shown in the following figure;

Step 3: Take photos with LCD screen. Canon EOS7D camera mode can only take pictures with LCD screen at present, as shown in the following figure;

4. Step 4: Click the button to record. After setting all the settings, you can click the button with a large number of English characters as shown in the figure to start shooting and recording. After clicking, we can officially start shooting the video we want, as shown in the figure below.

5. Step 5: Turn the focus ring to focus when shooting. You can turn the focus ring (not the zoom ring) in front of the lens to ensure that the face we see on the LCD screen is clear, constantly moving, constantly rotating and staring at the picture, as shown below.

6. Step 6: You can preview the video after shooting. After shooting, click the English button again to end our video recording. You can preview the video where the camera looks at the photos, as shown in the figure below.

Extended data:

Classification:

1, SLR camera

Dslr digital camera refers to a single-lens reflex digital camera, that is, digital, single lens, lens and reflex. Representative models in the market are common in Nikon, Canon, Pentax, Fuji and so on. This kind of camera is usually big and heavy.

2. Miniature single camera

Micro-camera has two meanings: micro-camera, compact, single-lens camera and replaceable single-lens camera. That is to say, this word means that this kind of camera is small in size and its imaging quality is similar to that of SLR. That is to say, micro-camera with SLR performance is called micro-camera.

3. Card camera

There is no clear concept of card camera in the industry. Only those small shapes, relatively thin bodies and ultra-thin and fashionable designs are the main standards to measure this kind of digital cameras.

4, telephoto camera

A telephoto digital camera refers to a model with a large optical zoom factor. The larger the optical zoom factor, the farther the scene is photographed. Representative models include Minolta Z series, Panasonic FX series, Fuji S series and Kodak DX series.

Advantages of digital cameras:

1. You can see the picture immediately after taking a picture, which provides the possibility of remaking the dissatisfied work immediately and reduces the occurrence of regrets.

Just pay for those photos you want to develop, and other unnecessary photos can be deleted.

3. Color reproduction and color range no longer depend on the quality of the film.

4, the sensitivity is no longer fixed by the film, and the photoelectric conversion chip can provide a variety of sensitivity choices.

5, the product structure is relatively simple, the appearance is more exquisite, and the product is more and more portable.

6. The digital camera is simple, clear and easy to use.

1. There is a switch on the right side of the camera viewfinder.

2. Turn the switch to the camera position to shoot video.

3. It should be noted that at this time, the mode dial cannot be in M range.

Note: you need to use a high-speed SD memory card, as soon as possible, so as to ensure the safety of photographic materials.

Expand knowledge:

The effect of shooting video by SLR mainly depends on the sampling data and coding method of the sensor. 70D provides a video format with the highest resolution of 1080p (long side is 1920). There are two formats for sampling and compression: all L and IPB. All-L is a low compression format, which can provide clearer and deeper video quality. Because the compression ratio is not large, it is very popular with memory cards. Frame rate, equipped with 30P and 24P (the higher the frame rate, the smoother. Generally, 30P is used to collect and travel videos, and 24P is used to make micro-movies. In addition, there is a 3.5MM microphone access interface on the side to ensure higher audio input.

How to set up a SLR camera to shoot video?

As the saying goes, sharpening a knife does not miss the woodcutter. Take a minute or two to check the following settings, which will make your pictures have the best visual effect and meet the technical requirements of professional production. Below, I collected how to set up the video shot by the SLR camera. Let's have a look.

Setting of shooting video with SLR camera

Set the resolution, frame rate and scanning mode.

Now I don't think anyone is shooting SD. Here we only talk about HD.

Hd has two standard resolutions: 1920x 1080 and 1280x720. For most novices, most of the films made are spread through the internet. In fact, the resolution of 720 is clear enough. Moreover, due to the small amount of data, the requirements for the capacity, storage speed and post-production computer hardware of 720 will be lower than 1080, which can reduce the economic investment of beginners.

There are several kinds of frame rates: 60 frames per second (actually 59.94 frames per second, for convenience, 60 frames per second), 50 frames per second, 30 frames per second (actually 29.97 frames per second, 30 frames per second), 25 frames per second, 24 frames per second (actually 23 frames per second). 60 and 30 are NTSC standards, and 50 and 25 are PAL standards. In other words, if your film is to be broadcast on TV stations in NTSC areas such as the United States, you should use a frame rate of 60 or 30; If you want to broadcast it on TV stations in China or Europe, you should use a frame rate of 50 or 25; The frame rate of 24 is the closest to the visual effect of the film (the standard rate of film shooting is 24 frames per second). If our film is spread on the network, then it is ok to choose any frame rate. I suggest choosing 24.

We have all seen slow motion in movies, TV shows or advertisements. These shots are shot with high-speed cameras, and then the variable speed effect is achieved through post-production. To put it simply: shoot at a higher frame rate and then play it back at normal speed, and you get a slow-motion effect. For example, if we shoot a shot with 50P and convert it into 25p (called "coincidence" in Final Cut Pro and "explanation" in Premiere) in the later software, the original 50 frames are still 50 frames, but the duration of this shot is changed from one second to two seconds, so we get a slow-motion picture equivalent to 50% of the original speed.

So, if you make a detailed plan before shooting, you can get a slow-motion effect by setting the frame rate when necessary. Most cameras need us to make the speed change effect in the later software, but some cameras can do it automatically.

There are two scanning methods: interlaced scanning (denoted by I) and progressive scanning (denoted by P). Different broadcast platforms also have different requirements for scanning methods. For network video, I suggest to choose the way of progressive scanning, which can get a better visual experience on the computer display screen. In addition, the video material shot by progressive scanning can achieve better results than interlaced scanning in the production of some late special effects.

In practical application, for convenience, we usually combine resolution, frame rate and scanning mode or both of them and describe them with some abbreviations. For example, some common technical terms: 1080p, 50i, 720p60 and so on. The following table lists the technical abbreviations of various video formats for us.

Of course, today's cameras don't have all the above formats, just a few of them. Different cameras often have different formats.

Set white balance

When shooting digital pictures, RAW format pictures can facilitate us to change the color temperature as needed in post-production, while video is different. Because the camera can only record highly compressed video images at present, we have very limited room for changes later. This requires us to set the appropriate white balance as much as possible in the early stage. If the color temperature of the light source is uniform, the automatic white balance of the fuselage can usually achieve good performance. But if you encounter the mixed color temperature of the shooting environment, it will be more troublesome. Cameras usually support manual white balance setting, which can be set according to the camera's built-in mode (such as sun, cloudy day, tungsten lamp, etc.). ), and some cameras allow us to accurately adjust the white balance directly in digital form. The following table lists the color temperatures of different types of light sources for us.

One thing that novices should pay special attention to is that accurately restoring white objects to white is not the standard for us to set white balance. Why? Imagine a blank sheet of paper under a green fluorescent lamp. Should we turn it green or white? Obviously green is more in line with most people's understanding. In addition, the setting of white balance is an important means to adjust the tone of the film. Imagine again: the same scene, the same dinner, the same couple, but they broke up tragically? Or a romantic and warm first date? Different story expressions may also affect the setting of white balance.

How to set the white balance has no correct answer, so it is a complicated problem. Beginners need more practice and thinking to master it skillfully. As for setting the white balance, my suggestion is that it can be set according to the skin color of the characters in the scene. The audience has a habitual understanding of people's skin color (obviously, if you paint a yellow person's skin color red, the audience will be very uncomfortable), so it will be a safer choice to adjust people's skin color to a color that conforms to the habit of watching movies. Of course, how to adjust the tone of the picture is not only dependent on the white balance, but also many other methods (such as lighting), which usually need comprehensive consideration. We will discuss this in detail later.

Set aperture and ISO

How to set the aperture is not much to say, everyone knows. However, when shooting video, the setting of aperture is sometimes different from that of picture shooting. When shooting pictures, we usually only need to consider a single picture, while when shooting videos, we need to consider the connection between the front and rear shots. For example, when we shoot a group of two people (that is, head-to-head shooting), the positions of the two people may lead to different ambient light, so we can't easily control the exposure by changing the aperture. Because the change of aperture will lead to the change of depth of field, and when you edit such two shots together, you will feel very uncomfortable. So in this case, we usually keep the same aperture when shooting two people separately to ensure the same visual effect, and use other methods to control the exposure. The above is just an ordinary example, and there are many similar situations in video shooting.

In the dark shooting environment, improving ISO can help us control the exposure of the picture to a proper degree. Nowadays, most cameras provide a high ISO value, which allows us to take visible pictures in a very dark environment. However, if the ISO value is too high, it will cause a lot of noise in the picture and affect the image quality. Therefore, when the light is not enough, the ISO value should not be raised blindly, but should be controlled within a suitable range. There is no standard for this so-called appropriate range. Different shooting projects, different cameras and different ranges. For example, in some news or documentaries, what is happening is irreversible. Of course, we need to take "shooting" as the first priority, so even if the image quality is lost, ISO will be improved to ensure normal exposure. Works such as movies or advertisements usually require higher quality.

For Canon EOS series SLR cameras, which are the most popular cameras at present, many experts and photographers in the network generally admit that 160 is its native ISO value, so when it is a multiple of 160, the picture noise is less and the picture quality is the highest. My suggested ISO values are:160,320,640,800, 1250. Do not use ISO higher than 1600 to shoot video on Canon SLR.

Set shutter speed

Shutter speed setting has three functions:

1. Adjust the visual fluency of the action in the picture (the action of the fuselage) and the action in the picture (the action of people or things in the picture).

2. Adjust the exposure.

3. avoid stroboscopic.

1, adjust the smooth movement. Friends who have experience in photo photography know that the faster the shutter speed, the clearer the captured action. But when shooting a video, if the shutter speed is set too high, the motion in the video (including the motion in the picture and the motion in the picture) will become unsmooth. My suggestion is to set the shutter speed to double the frame rate. That is, if your frame rate is set to 24 or 25, the shutter is set to 50; If your frame rate is 30, set the shutter to 60; If the frame rate is 50, set the shutter to100; If the frame rate is 60, set the shutter to 125.

2. Adjust the exposure. The slower the shutter speed, the greater the amount of light entering; The faster the shutter speed, the smaller the amount of light entering. So the shutter can also adjust the exposure. In most cases, I suggest setting the shutter speed according to the above double principle and adjusting the exposure by practical means (aperture, ISO, filter or lighting, etc.). However, if other means are exhausted and the exposure is still insufficient, then we can also consider reducing the shutter speed appropriately to get more light. However, it should be noted that the minimum shutter speed cannot be lower than 30. If the light is too strong, you can't reduce the exposure by increasing the shutter speed (however, if you only shoot scenes without fast moving objects with a fixed lens, in fact, increasing the shutter speed has no effect on the visual effect).

3. avoid stroboscopic. Some artificial light sources we usually use (such as fluorescent lamps) are actually flashing at a certain frequency, but our naked eyes can automatically adapt to this flashing, which will make us feel that the light is continuous. But the camera will record this flicker truthfully. What is shown is that flashing stripes will appear constantly in the taken pictures.

If we shoot with NTSC system in areas where the power supply frequency is 50Hz (such as China and Europe), or shoot with PAL system in areas where the power supply frequency is 60Hz (such as the United States and Japan), we are likely to encounter this situation.

Adjusting the shutter speed can help us solve this problem simply. We just need to set the shutter speed to a multiple of the local power frequency. For example, in the 50Hz region, set the shutter speed to 50 or100; In the 60Hz region, set the shutter to 30, 60 or 125.

Set style file

This thing has different names in different brands of cameras. For example, Canon calls it "PictureStyle"; Panasonic called it "movie mode". Here, for convenience, let's call it Canon's name "Style File" (because Canon has the largest number of users, and this function of Canon SLR is also the most powerful).

What exactly is a style file? We know that in the original film photography, different kinds of films will show different colors, contrasts, sharpness and tones, which is called "different tastes". The same is true of style files. By using different style files, we can easily make our images achieve different "flavors" without complicated post-color matching.

Most cameras have several sets of style files built in for us to use when shooting. Some cameras also allow us to further adjust parameters such as contrast, saturation and hue on the basis of built-in style files, and can be saved as customized files for our convenience at any time. Canon also provides users with editing software for style files, which allows us to carefully produce unique style files according to our own preferences in the computer.

Style files are ever-changing and have no certain rules. Make your own decisions according to the theme, environment and personal preferences. So, how to determine what style file to use? We consider it from two directions. We can achieve the desired color and tone in the early shooting through the cooperation of style file, color temperature and color shift. You can also try to keep more details and greater tolerance in the early stage, leaving the maximum space for color matching in the later stage.

Canon camera supports importing and using self-made style files, so there are some unique style files developed by professional companies and individual users. One of the most famous is Cinestyle. Using Cinestyle can significantly improve the quality of video shot by Canon cameras, making it easier for users to make more "cinematic" video images. Highly recommended to Canon users.

Set audio

Audio function has always been the weak link of the camera. Most cameras do not allow users to manually control the audio level, and there is no real-time audio meter, XLR audio input interface and audio output interface for monitoring. If there is an external recording device, these problems can be solved; If not, we can only do our best.

If your camera can control the volume manually (for example, Canon5DMarkII), you need to adjust the volume according to the actual sound of the shooting scene. It's best to record a paragraph first and then play it back. If your camera can display real-time audio level on the screen (for example, PanasonicGH2), please make sure that this feature is turned on.

The built-in microphone on the camera basically can't meet our demand for sound collection. Most people will choose an external headset microphone to improve the recording effect. When using an external microphone, be sure to turn on the microphone switch. I made such a mistake when shooting with a 5DM Mark II. In this respect, I like the thoughtful design of GH2. When an external microphone is plugged in, it will display a sentence on the screen, prompting you to turn on the microphone.

Check the remaining capacity of the battery and memory card.

Remember to check the remaining capacity of the battery and memory card before shooting. This is an extremely simple but easily overlooked operation. This is especially important when shooting some unrepeatable scenes such as news or live performances, because once missed, it can't be made up. In interviews, advertisements or film and television drama shooting, if the shooting is interrupted due to insufficient remaining capacity of the battery or memory card, it can be replaced before shooting, but it will also hurt the creative mood of the subject, other members of the film crew and even yourself, and will leave an unprofessional impression on others. In fact, we only need to spend dozens of seconds to check before shooting, which can completely avoid this situation.

Matters needing attention in shooting video with SLR camera

Calculation method and selection of shutter number

Shutter speed is one of the parameters to control exposure, and it can also determine the fluency and effect of the film you shot during video recording. As for the commonly used 24p for making movies, how much should the shutter value be set before shooting? If you want to clearly shoot every movement and behavior of the subject, you can set the shutter number to twice the number of frames, that is, if the number of frames is 1 sec, you can increase the shutter speed to 1/50s, which is safer, but if you pursue the afterimage effect when the object is moving, you can reduce the shutter speed. After setting the shutter number, try not to change it at will during shooting.

Aperture determines depth of field

In photography, the aperture size can not only control the light entering the camera, but also use the large aperture to create a beautiful shallow depth of field to highlight the theme. Whether you choose a large aperture or a small aperture, it is still not recommended to change the aperture size when shooting. It's best to pause adjusting the value, even if you are using a film fixed-focus lens with stepless aperture and zoom ring. Of course, this kind of lens is very suitable for shooting, especially when zooming manually, and it is easier to shoot the feeling of focus shift that is common in movies. It is also smoother when zooming.

On ISO value in dynamic video recording

The choice of sensitivity determines the details of the film picture, similar to still photography. When your sensitivity is higher, the graininess or noise is more obvious. As with the first two parameters, it is best not to change the ISO value when recording, so as not to affect the whole exposure.

Exposure: the Difference between Instantaneous and Persistent

Generally speaking, as far as we know about still life photography, the exposure is determined at the moment when the shutter is released. Even if you need to fill the light, you can also use the flash to assist. Dynamic video generally emphasizes constant exposure. Unless special effects are created, there will be no obvious exposure change in the film scene, otherwise the flickering visual effect of the film may not be very good.

Choose the right shooting mode

In order to control the settings in the camera and achieve a stable exposure effect, it is recommended to use manual mode when choosing the shooting mode, because there are uncontrollable factors in automatic, aperture priority and shutter priority modes, and only in manual mode can the parameter settings be fully mastered, which is less affected by environmental changes.

How to shoot video with a SLR camera?

Question 1: How does Canon SLR shoot video and what are its shooting skills? Turn the mode dial to the position marked by the camera, press the live view button on the left side of the viewfinder to start shooting, but first set the lens to manual focus, and manually adjust the focus according to the focus used during shooting! By the way, the video quality shot by SLR is very good, no less than that of ordinary camera, but the operation is very troublesome and inconvenient. Taking video for a long time will reduce the service life of the image sensor!

Question 2: How to record video with a SLR camera? Each brand operates in different ways. Switch to real-time view and you can record.

Question 3: How to choose the video format shot by SLR camera! Of course it is 1920* 1080. The picture quality is good. Full HD video. The minimum picture quality of a large LCD TV is 1280*720, otherwise the picture quality will be chaotic.

50P, 60P, 30P and 25P refer to the number of images per second, with 24 old movies per second. Of course, 50P and 60P are better for shooting high-speed moving objects, such as athletes running and cars on highways.

IPB and ALL-I, like Canon 5D3' s 1080P full HD, have two options: IPB and ALL- 1. IPB is 235M/ min, and all-1 is 685M/ min. Of course, the video quality of ALL- 1 is still good.

It is really good to shoot the video with the highest bit rate, which requires post-production of video conversion software. Please keep the video resolution and appropriate size. A genuine Blu-ray movie 20-30G.

Question 4: How to open the viewfinder when shooting video with a SLR camera? When shooting video with a SLR, you can only use the screen to view the scene, not the optical viewfinder. this is

Question 5: How does Canon SLR shoot video? Turn the main turntable above to video mode, first press the shutter for half a turn to focus; Then press the video shooting button, and the shooting button is also displayed in real time for shooting; When you stop shooting, you also press the video button. My SLR is 600D, that's all, but the steps of Canon's SLR video recording should be similar!

Question 6: How does Nikon 3200 SLR camera record video? First press the "LV" live view button on the back panel to turn on the screen view state;

If you want to record video, press the "red dot" button next to the shutter of the body switch to start recording. If you want to stop, please press the "red dot" button again to record the video.

To play the recorded video, first press the "triangle" play button. If it is a video, the border of the movie graphic will be displayed. Press the OK key to start playing.

Question 7: Can I shoot video with a SLR camera? How to understand this injury?

My first 5D3 was bought as a video camera, which took two years and took more than 400 hours. Now it looks brand new ~

I just bought the second 5D3 the day before yesterday. Compared with the two, the old machine has begun to have faintly visible thermal noise in the same scene. At the same color temperature, the picture of the old machine is obviously red, and the noise in the material is higher than that of the new machine ~

There is little difference in taking pictures, but the noise is a bit high ~

Compared with the camera of the same level, the image quality of SLR is not bad, but why it is cheap is because it doesn't have a complete cooling system. When the SLR camera is turned on for a long time, the sensor temperature will rise and the heat will not be discharged ~

But depending on what you think, my old 5D3 earned me more than ten times the capital, so I think this problem is nothing ~

Question 8: How to choose the video format shot by SLR camera! Of course it is 1920* 1080. The picture quality is good. Full HD video. The minimum picture quality of a large LCD TV is 1280*720, otherwise the picture quality will be chaotic.

50P, 60P, 30P and 25P refer to the number of images per second, with 24 old movies per second. Of course, 50P and 60P are better for shooting high-speed moving objects, such as athletes running and cars on highways.

IPB and ALL-I, like Canon 5D3' s 1080P full HD, have two options: IPB and ALL- 1. IPB is 235M/ min, and all-1 is 685M/ min. Of course, the video quality of ALL- 1 is still good.

It is really good to shoot the video with the highest bit rate, which requires post-production of video conversion software. Please keep the video resolution and appropriate size. A genuine Blu-ray movie 20-30G.

Question 9: There are two ways to focus video with SLR. One way is to focus by half-pressing the shutter, which is as slow but accurate as real-time focusing of SLR display. The second is to adjust the lens to manual mode and focus by yourself. Focusing speed is slightly faster, but the accuracy varies from person to person. SLR is not a camcorder, nor does it have the automatic recovery system and function like camcorder. Therefore, it is best to shoot a still close-up with a SLR, and it is difficult to achieve motion focus.

How to shoot advertisements and how to shoot good promotional videos.

1, the equipment for shooting promotional videos is particularly important, because the definition of shooting quality directly affects the definition of screen resolution on computers, mobile phones and other equipment. Even post-production will affect the audience's love for your video.

2. As the saying goes, "A clever woman can't cook without rice", so if you want to shoot a good promotional film, you must have good materials and creative themes, otherwise it is difficult for a good camera to shoot a wonderful promotional film.

3. For good materials and novel creative themes, first of all, we should design a good publicity plan, brainstorm, collect relevant information, and make a systematic proposal under the circumstance of highlighting the theme.

4. When shooting a promotional film, the key point is to give people a sense of beauty while highlighting the theme, pay attention to the matching of shooting scenes, lighting and colors, and pay attention to the handling of shooting details.

5. In the promotional video, it is suggested to apply a little domineering propaganda picture appropriately to make its picture play the role of finishing touch. Although people sometimes have a little knowledge, in general, they still have to return to the theme. It works better this way.
