Apple Pro Res and H264 --same sequence even possible?
on Oct 27, 2011 at 7:33:55 pm

Hello,

I hope you all are having a nice day. I have received H 264 and Pro Res 422 footage in a FC7 project which I am running on a Mac OS X.

I am well aware that H264 is not an editing codec. I just want to make sure my workflow sounds good to you folks out there.

I plan to trancode/convert the H264 to ProRes 422 footage in compressor and then reimport into my project with the sequence set at Prores.

Is there anything that I am missing that I should be aware of? Your help is most appreciated. Thanks, Margaret

Sounds perfect to me. You can batch convert in Compressor (probably what you were planning anyway), but keep in mind that the preset for ProRes 422 in compressor is set to pass-through the audio, so if the audio in your H264 clips are of a compressed variety (ie: AAC or MP3), you will have problems with your audio in FCP7 unless you convert it to aif.

Andy is correct... However, the Compressor preset can be customized even though it is set to by default to pass through the custom settings of your original audio as Andy mentioned. So, you can do it all in one pass if you set the audio parameters properly, if you need to that is.

Andy,

Thanks so much for your quick response. I really appreciate it.

How do I find out the details of what the audio format is (whether mp3 or AAC)?

In movie inspector of a converted ProRes test -- it says

Apple ProRes 422, 1920 × 1080 (1888 × 1062), Millions
16-bit Integer (Big Endian), Stereo (L R), 48.000 kHz

What will be my problems with the audio if I don't convert? Most of the H264 are B roll so it might not be an issue.

Again, thanks for your time. Margaret

You're good. If it says 16-bit Integer (Big Endian), then it's already in a useable format. It would say AAC or MP3 (or Mpeg) in the info if it was one of the compressed, unusable formats.

Also, just to clarify from my first post, I wanted to imply that you could change the preset to convert prores content to aif while converting the video, but I guess I didn't make that clear. Luckily David did.
