24p omission explained?
This source explains why there's no 24p at the moment. I'm trusting the information is legit, I personally lack the technical knowledge of HD video in the 5D2.
“The 5D MarkII will have 24p, it is already in a firmware running in testing. It was not released due to time but it was planned to be released with the manual control. This is not as easy as some people tend to believe. The codec data rate has 6 frames of spare bandwidth and the file size was still the same as the 30p in the cam I tested. They have to re-code the compression routine in order to run at full speed and not waste file size. This has introduced some problems in stability because the chip can only handle 30p natively and this is basically a hack. No Audio control planned or in the firmware as of yet.
The 60D will have 720p, 1080p video modes. 30p is already in the firmware and the Mark II hack could be used in this camera easily. Much better CMOS than the 500D improved even from the 5D Mark II.
Nikon is adding most of the same features soon in their cameras, Canon just wanted to release and get the claim of being first.”

I like to watch Veronica Mars episodes as well Lost. I found your blog on google and read a few of your other posts. I just added you to my Google News Reader. Keep up the good work. Look forward to reading more from you in the future.
I’m new here with canon or any other cameras, so I want an answer about is that ok if I make a movie with 25 Hz film and use it in analyzing program as a 50 Hz film.
Is that ok the concept that we can divide the film was taken with 25f camera to be 50f.
I made numerous shots with the 5D2 in germany but with the manual control available now. The flicker problem is no problem. Shutter set to 1/50 and I never run into flicker problems. It could record 45fps, and there would not be a problem ;-)
Peter T. is absolute correct: It is a PITA to do the post process with that 30p stuff to do a normal PAL DVD. There are workarounds for that, but they do cost so much time and the most workflows are bad hacks. If I would blow up the workflow to achive best quality, it expandes postprocessing time to be 10 times longer. And because of all that tech waiting and conversion work you loose the look for the story.
The workflow is is the problem, and thats why I desperatly want the 25p update. The only, but important reason.
>> Technically speaking, the quality will be better if I were to convert 30P to 24 or 25P
Thats not true. Conversion from one frame rate to another is highly problematic and introduces blurring / artefacts. The older, simpler method that is still most widely used is a pulldown, such as a 3:2 pulldown. Its really nasty and essentially blurs frames together which introduces ghosting. Most NLEs still use this method.
The other method is to use intelligent retiming which interpolates through flow. This is very complex and slow and doesnt work in all circumstances. It can also introduce artefacts.
Thats why its important to shoot at the native rate you need. If the 5D2 shot at these rates, there’d be no discussion here.
“Can’t we just get along the idea that a DSLR is not a video camera?” Sorry, but now that video exists on this DSLR it NOW becomes a video camera.
