How to automatically save photos taken by a computer camera in a fixed format?

Nowadays, with the popularity of this digital device, it is not uncommon to buy a DV camera to shoot your own VCD. But at present, DV cameras are still too expensive for home users! It is difficult to popularize at once. The author bought a Meida online dating camera for computer the other day, and the price is only 128 yuan. The author thought for a moment, why don't you take your own video with this camera, and you can also play VCD to do DIY.

First, hardware preparation

You need a camera to shoot VCD (the best resolution is 640×480, and the number of frames can support 30 frames). This way, the picture effect of VCD will be better. Besides, we need a highly sensitive microphone. Due to the high CPU speed when shooting, it is recommended to use CPU above Celeron 600 and hard disk above 20G. If you want to shoot on the move like DV, it is recommended to use a high-performance laptop to connect the camera. So you can shoot with a laptop. Of course, the lighting should be better. It is recommended to shoot after the scene is fully arranged.

Second, the specific software operation process

Save camera video in AVI format, and the file in AVI format is quite large. The author's 3-minute video is actually 450M, so if you want to record a VCD for a long time, please put the storage location of the video file in the hard disk partition with at least 8GB of remaining space.

After recording the AVI video file, please restart the computer first to eliminate some memory fragments, which is convenient for Nero to burn (download address:) and prevent it from crashing when burning. Then start Nero, press the New button under the File menu or "New" to open the "New Compilation" dialog box, and select the "VCD" we want to burn.

To ensure that the VCD you carved can be played on the home VCD player, click the "ISO" option, and it will list several options for you to choose from. Since most home VCD players can only recognize the international standard of ISO 9660, here we need the file/directory name length of ISO 1 and the character set of ISO 9660, so don't relax the restrictions of ISO.

Then drag the AVI image file on the hard disk to the CD version of the audio track. Nero will check the AVI file to make sure the recording is successful. In this step, you should pay attention to dragging the image file to the audio track window at the bottom of the CD-ROM panel, instead of the mpegav directory where the dat file is stored after burning. This is very important!

Click the Burn button to open the Burn dialog box, set the burn options, and then press the Write button to start burning. In order to ensure the success of burning, do not run other programs and remove the screen saver when burning. Nero will first convert AVI files into dat files when burning, which will take a long time! Because it has a process of compressing AVI into dat files. Therefore, friends who have filmed VCD for half an hour should be prepared for a conversion time of up to 3 hours.

After making the VCD, the author put this self-made CD into the VCD player at home to watch. I feel that pronunciation and mouth shape don't match. It seems that my computer operation speed is not fast enough, and because of the camera, it looks blurred on VCD. It seems that to make a satisfactory VCD disc, you must have strong hardware support.

Nowadays, many families have their own cameras. Because many people's Putonghua is not standard, the sound effect of the video is difficult to accept. Usually, when we watch some news programs or TV series, we often see subtitles synchronized with the speech content at the bottom of the screen, which makes the whole program look clearer. Therefore, when making some home videos or shooting some DV movies, we will add subtitles, and the effect will be very different.

There is no difference in the principle of subtitle production between DV and TV. The difference is that the production of such subtitles is relatively large. When a movie comes down, there may be dozens or hundreds of lines. If you use editing software to make subtitles, you have to make as many subtitle files as there are lines in the movie, which is too much work. We can solve this problem with the help of some third-party software-Leite Video TGA Lyrics Generation System (subtitle plug-in of Canopus editing software), which supports professional synchronized subtitle production and can greatly improve our work efficiency.

Step 1: When the software of RTG video TGA lyrics generation system is started, a new file will be created automatically, and a property window will pop up asking us to set it. In the Lyrics and Fonts tab, there are some very common attributes, including aligned western fonts. Needless to say, the font size and the spacing between rows and columns here. Generally, VCD is made, and the font size is suggested to be 64.

Step 2: In the Brush tab, you can set properties, such as text filling and transparency. There are three ways to fill text: monochrome, transition color and bitmap. After selecting each item, you can make further settings in the color palette on the right. For the transition color setting window, you can select the key color of the transition color on the color swatch. In the Border tab, the main purpose is to set the text margins to make the text look fuller. The specific options are basically the same as those in Painting Brush. The "Size" column is used to set the thickness of the margins, which is generally set to 2. After selecting the "solid edge" label, the text can have a certain three-dimensional effect. The Shadow tab contains attributes such as the direction, distance and ambiguity of text shadow. Different settings can be made according to different occasions and the meaning to be expressed.

Step 3: Click "OK" to enter the subtitle editing window, where you can enter or paste the subtitle content, or directly guide the text file, where each line represents one line, and we should pay attention to the broken lines at the segmentation of each screen. Pay attention to adjustment when entering. If you need to adjust the caption attributes after input, you can select "View Lyrics Attributes" (Ctrl+A) in the menu to modify it again. After all the settings are completed, select "view and generate a lyric" (F 10) in the menu, fill in the sequence file name, and generate a subtitle file. Each line generates a TGA file, and dozens of subtitle files are completed instantly. Is it very efficient?

Step 4: Just import the subtitle file into the editing software, just like importing other subtitle files. Give a brief introduction. Take Premiere6 as an example. First, select "File → Import → File …" menu in Premiere6 to import subtitle files, select all the imported files in the project window, and then drag them to the video track in the timeline window (note that it cannot be a video track). Next, right-click the subtitle file material selection menu "Video Options → Transparency …" to set the transparency attribute, select the transparency type value as "Alpha channel" in the pop-up menu, and then click OK, and the subtitles will be easily superimposed.

This software is widely used, not only in news subtitles, movie subtitles, but also in making synchronized lyrics of MTV. In short, it can easily cope with the production of batch subtitles. Come and try it quickly!

Why does the picture of 1 have a sawtooth shape and the transition edge is not clear after output?

A: Most of it is caused by the incorrect setting of the Fieldx field in your project settings. You should select the No Fieldx option in the drop-down menu. Please refer to article 6 in the project setting help. Furthermore, if you apply the Hollywood plug-in, it is normal that the output special effects screen has some jagged roughness, because we use software to compress the video. If you use a hardware video compression card to output, the effect will be greatly improved and the output quality will be good, but the video compression card is very expensive.

2 Why does it take 6 seconds (150 frame) to drag and drop the edited picture material onto the track?

Answer: This time is the default time for still pictures in Premiere. You can change this setting, select General and Still Images commands under Preferences under the Edit menu of Premiere, and then change the value under Still Images in the pop-up Preferences dialog box. You need to re-import the material to take effect. If you import a sequence file in Gif format, you should set the value to 1 to import the file into the track to keep the animation of the original file.

3 Why is the preview speed so slow?

A: Please refer to Item 6 of Project Settings in the Help. Select the "From RAM" option from the "Preview" drop-down menu to preview from memory instead of from disk. Preview speed will be significantly improved, provided that your memory is large.

Video output time is too long, is there any way to shorten the output time?

Answer: Yes, it takes a long time for Premiere to output video files. If you want to improve completely, you can buy a video compression card output, which is about 1: 1 real-time output. If there is no money to buy it, it can be solved by the following methods. First, pay attention to the screen size of the video file you output, not too big. We can keep the picture size of VCD at 352*288. If necessary, try to reduce the output screen size setting, which will improve the output speed and shorten the output time. Moreover, the project you edit should occupy as few tracks as possible. The more tracks you edit, the longer the output time will be. Also, if you apply many filter settings and external plug-ins, it will also affect the output speed. It is normal for us to use software to output video files for a long time. You only need to pay attention to the above problems, which will improve the output speed and shorten the video output time. Finally, I tell you an experience, that is, the output speed of still pictures in BMP format is the fastest.

Why are my imported photos distorted? (or what about the black boxes on both sides of the photo? )

Answer: It is because the picture size of our project is different from that of the monitor, and the ratio of the two is different, so the picture is deformed in the monitor. That's why there are black boxes on both sides of the photo. The difference is that the pattern of the photo is not deformed. To solve this problem, you can use drawing software to process photos and set the size to 352*288. For vertical photos, you can increase the white space on both sides of the background, or you can re-create the photo as a banner, but the size remains 352*288. You can also right-click on the material and select the option to keep the proportion of the material in the shortcut menu, so as to keep the original proportion of the material and ensure that the material (photo) is not deformed.

How big is the pixel of the picture we choose?

A: The resolution of the TV is 72 pixels per inch, so the resolution of the picture we choose is above 72 pixels per inch. The resolution is too high to be useful, generally between 100- 150.

7 why am I installing Premiere, but I am prompted that QuickTime is not installed, and the QuickTime option is not available?

A: Many of our friends don't use genuine Premiere, and there is no Aauto Quicker player in the installation directory. Because Premiere supports MOV format of output stream coal, which is a special format of QuickTime, you can't output video files in MOV format because you don't have QuickTime player installed. Also, the transition settings about Quick Time are not available in the transition settings, so when Premiere prompts you that QuickTime is not installed, some options of QuickTime are not available, which can be solved by installing QuickTime.

8 Why can't Premiere output video files in MPEG format?

A: Actually, Prime Minister. Version 0 can output video files in MPEG format, but only according to the plug-in that comes with *, and the effect is not very good. You can select plug-ins to output video files in MPEG format. The best output quality is TMPGEnc, which is known as Japan. Many netizens agree that its output quality is the best, but it is troublesome to install and use. Personally, I think Panasonic _ MPEG 1 _ Encoder _ Plug-in _ V25 1 is good, with fast speed and good output quality. The output process is just like Premiere itself, and the widely used LSX-MPEG is also good. Once you choose to install, you can output MPEG video files in Premiere. The latest version 6.5 can output video files in MPEG format, but the effect is average, so it is recommended to choose plug-in for output.

Why didn't you talk about the application of filters in the tutorial?

A: We don't usually use many filters, so there is no explanation. You can refer to the filter settings of the material in my template, and then learn by yourself. The most important thing is to learn to control the key points.

10 I want to output some video material. What should I do?

Answer: Refer to 1 and 2 preview ranges in About Preview, arrange this preview range to the range you want to output, refer to Article 4 in Output Settings, select the work item output workspace as the range item, and output the part you want to output.

1 1 Why can't I use the plug-in of Adobe Premiere's Final Effects under WIN98 or WINXP?

A: The final effect of many friends using Adobe Premiere. It can create many video special effects, such as rain and snow and particle effects. Is a common special effects plug-in for Adobe Premiere. Many people used to find, use and speak online. After Adobe Premiere6.0 came out, because its original powerful functions have been further improved and perfected, most friends who like video editing are now using Adobe Premiere 6.0, but then the question about the final special effects of Adobe Premiere comes. I often see some netizens talking about the final effect of Adobe Premiere on the Internet. Besides how to use it, I can sum up the following points:

(1) Chinese version (or English original version) can't be used after installation, and the final effect of Adobe Premiere can't be found in premiere.

The reason is that the installation path of the original English version is wrong, and the installation of the Chinese version may be that you did not put the copied file in the plug-in directory of Premiere correctly. I made an automatic Chinese installation version, which is convenient for users to install and use, and avoids installation errors. It can be downloaded from this website.

(2) It can't be used in Adobe Premiere6.0 version 6.0 or it is easy to crash.

The reason is that the real crash may be the problem of your system itself. It can be started in most cases, but it doesn't work well or is not used normally. The reason is caused by the software itself, because this software version was originally developed for Adobe Premiere version 5.1,and the support for Adobe Premiere version 6.0 is not enough. (I can't find its high-end version) I have to make do with it! It works normally in Adobe Premiere versions 5.1and 5.5, but in Adobe Premiere version 6.0 under WIN98 system, the most common one is false crash. When the effect is applied to the material (the mouse turns into a fist shape), just click Enter, and then click Settings in the plug-in effect control to restart. Everything will be fine. In the new version of WIN XP, if this happens, you just need to move the mouse to the title bar of the system tool below and click it. Can be set directly.

12 why can't the Hollywood FX for Peremire filter plug-in add pictures and video materials to the editing layer when it is used?

A: Some people think that the Hollywood FX for Peremire filter plug-in is not registered, so this function is not supported. Others say it's not necessary at all. Hollywood Tungsten is a powerful video filter plug-in with hundreds of transition settings. Isn't it a joke that it can't be used? What some people say above is actually wrong. Hollywood FX Hollywood Tungsten does not support common picture files such as JPG, GIF and BMP. It only supports image files in label format. All you need to do is to use the image file in tag format. Similarly, for dynamic video files, you can use MOV format to handle them. Please experience its unpredictable changes quickly!

13 why do I edit and output video images in AVI format with poor quality and sometimes mosaic?

Answer: The main reason is that the wrong compression code was selected when outputting. A good compression coding has a great influence on the quality of video output. Can I choose Intel Indeo under WIN98? Video 4.5 You can choose Indeo under WINXP? Video5. 10 works well. You can also install an external encoder, such as DivX DVD encoder, to support MPEG4 encoding. Choosing a good encoder not only affects the output quality of video, but also affects the size and output speed of the generated file, which is a very important link.
