Why do many short films and even some movies use 5D2? Find a solution

I can't believe I saw someone say that 5D video can reach the movie level in my answer? Can't stand it, this must be said! Well, as a late dog who has processed countless 5D materials, let me express my views on 5D:

For serious projects, even if you use a home camera, don't use 5D, whether it's 2 or 3.

1. The image quality is extremely poor: 5D has no 422proRes or similar HD video output scheme, and there is no SDI bypass output. What you can get is a low bit rate, heavily compressed h.264 mov format. If the official firmware is not brushed by a third party, the code stream will be about 35M, and it will be 50M after brushing!

2. Due to the above characteristics, there is not much room for color matching after 5D. I believe I have a say in this. Generally, the 5D material I get will be converted into 422 format with the official finalcut collection plug-in, but this is only a real-time preview for editing, and there is no improvement in image quality. Move the curve a little and the highlights will explode. I believe that students who have adjusted the 5D material must have a deep understanding of this. To reach the so-called film level is simply an idiotic dream!

3. Because of the blind hole of the shutter structure, 5D greatly limits the motion of the camera during shooting. The famous "jelly effect". Because it is a "camera" after all, and it uses a rolling shutter, this is an unsolved problem in the design structure. Why don't you try to take a follow-up photo with a 5D hand? ! Oh, you said this is the "style" you want to pursue. Well, I have nothing to say. I hope your Party A will pay the bill.

4.5D has no time code. Of course, you can say, "I can hit the board directly!" " Alas ..... I can't blame you for not cutting the movie. Maybe you haven't seen me fly into a rage and want to kill someone when I fired an intern who lost DPX's "embedded time code". In today's digital film production, high-speed photography above 50P has become the normal production frame rate. What if your photographer gives you a 60P shot material and your 5D mixed editing material has no time code, but you have to lip-synch? What should you do? Of course, no crew member in his right mind would do such a heartless thing.

5. I know you will say that even 4k and HDR videos can be released through firmware. I can only say that 4K is really useful, which can improve the definition of 2k finished products, but HDR is just a cloud, because recording HDR color information requires the file format to support colors above 10bit, otherwise you will only see the effect of HDR, not HDR video.

6. There are all kinds of other similar lens breathing effects, such as extremely light body, bad hand feeling when shooting, limited shooting time of one lens and so on. ...

In short, unless you are sure that Party A can accept the quality of 5D, don't be fooled by your Party B to fool around with 5D.

1.5D You can take photos of some complicated seats. Because the fuselage is small, sometimes you can win by taking some pictures. In this extreme case, it is no problem to go to 5D.

2. Cheap, really cheap. With a huge lens group, photo photography can instantly shoot MV across borders! A full set of lenses plus a tripod and a small supervisor, plus a crew member, is only 3500 a day (this is the most expensive price)? Can a 32G card be shot for two hours, properly thrown into the final and cut directly? Wedding companies love it! (Yes, the quality of 5D video is wedding-grade. )

3. Noisy media; Of course, first of all, when Canon launched 5D2, only the good ones were selected. A bunch of enthusiastic photographers clamored for the arrival of the era of cheap film shooting with a large number of post-processing videos. Even Jia was invited by Canon to speak for him. At that time, I was also very excited. The photo quality of Canon Red Circle Group can finally be transplanted to video at zero cost. To what extent, I will start directly! But practice makes true knowledge, you deserve to be cheated. Compared with the huge later cost, that eye-catching sugar water tablet simply can't make ends meet.

4. "The customer knows a chicken feather!" Well, this is the original words of a producer of Party B (I am Party C). When customers' understanding of the so-called "movie level" is limited to "blurred background" and "2k HD", countless local 4A finally found a way out, and even filming micro-movies with 5D has become a fashion. I've seen great crews, too. I'd rather use 5D3 than C300. Of course, you can't hand in the film with one mouth, but I think, if the budget allows, don't be sorry for your heart. Typing at the bedside, please say if you have any mistakes. ...
