Should I of 5D H.264 to ProRes?
on Aug 10, 2011 at 10:48:04 pm

Hello,
I am using Adobe Premiere Pro CS5.5 and I have some footage shot on Canon 5D Mark II. Premiere can edit the H.264 footage without having to render on every edit I make.

Should I convert it to ProRes 422 anyway through a mac? This question arose when I heard that it is better to do compositing and colour grading on transcoded ProRes 422 footage even though there is no increase of quality.

Can any experts here verify please?
Cheers!
Kew

Without knowing your platform, OS and proposed workflow, it's going to be difficult to give you a straight answer. For example, if you're on a Mac, do you want to work in Color, even though you cut in Premiere?

Good morning Dave.

I work on Windows 7 PC, Adobe Premiere Pro and After Effects mainly.
I often need to give finished vfx shots to people on FCP though, but only when everything is done on After Effects. Does the answer differ from the platform I am working on?

Thanks!!
Kew

The platform makes a BIG difference. Windows machines can't write to ProRes, for one thing. That's a little problematic for you, no?

You shouldn't have to convert anything when you work Windows-only.

For an FCP-Windows-FCP trip, it's a little different. You should also get Quicktime Pro for Windows, version 7.x... the latest version of QT 7, whatever it is. Best 35 bucks you'll spend for quite a few months. Avoid QT X like the plague. You'll then be able to read ProRes HQ & LT, but not write to these codecs.

I cut on FCP at work, and run AE on a Windows box at home. When I bring work home, I export to ProRes HQ, edo my AE voodoo, and render PNG IMAGE SEQUENCES. It's a lossless round trip, and it's no problem for FCP users to open image sequences in QT Pro and export in the codec of their choice. Todd Kopriva, the guy in charge of After Effects customer service, for Adobe, does the exact same thing.

Hi Dave,
This workflow sounds excellent. I noticed in AE we can export to .mov container in PNG codec, is that the same as a PNG image sequence?
Someone suggested JPEG2000 in .mov container as well, do you have any comments?

No, but the file sizes will be slightly smaller and like a PNG image sequence, it will be both lossless and support alpha channels.

Unless otherwise directed by your FCP folks, I'd stick with PNG. It's won't hurt to discuss it with them.

Dave,
You are brilliant, thanks! I will definitely discuss it with FCP guys!
