Pro Res 422 – Love it or Hate it?
I captured about two hours of 720p 59.94 material in Pro Res HQ. As I am working with it, I notice that all the video is “jumpy” when played back through my canvas AND my Kona LHe. Tried a re-render, tried everything under the sun you can think of. The only solution that worked was putting all this pro res material in a uncompressed 10-bit timeline and editing there. This results in ultra slow renders and is a waste of render file space since I was originally trying to save space by capturing Pro Res, but the jumpies are fixed in uncompressed 10bit.
I have another HD shoot coming up and I do not have all the storage for capturing to uncompressed 10 bit 720p, and I do not want to mess with Pro Res anymore…should I try DVCPRO HD instead?
What have your experiences been with Pro Res?

There are a lot of variables that can effect the performance of ProRes. I’d recommend capturing some of the same footage with the ProRes “medium” quality 145Mb setting and see if that works better.
The only reason I’d consider using the ProRes HD 220Mb is if I were mastering to film. DVCProHD is 100Mb, Sony SR is 140Mb, so 145Mb should be plenty for mastering to HD.
If that doesn’t solve your problem check out the SheerVideo codec. Although it doesn’t compress as much it is much better than editing uncompressed, is lossless, 8 or 10bit, YUV or RGB and has an embedded alpha.
DVCProHD will work, but I only use it as a last resort.

Is it at all possible to post this jumpiness?
Was this a project that started on FCP5 and upgraded to 6?

Why not a fan of DVCPRO HD? I would like good quality, but ultimate destination for the spots is SD Beta. And yes, I will try to upload some “jumpy video”. Try to imagine playing frames 1-30 and it skips frames 12-16 and 26-29.

What kind of processor do you have?
Give more specifics about your setup.

[Chuck Spaulding] “DVCProHD is 100Mb, Sony SR is 140Mb”
Don’t just look at bitrates.
DVCProHD downrezzes to 1080i and 720p to 1280×1080, and 970×720, respectively. This allows it to “cheat” and achieve less compression per pixel. Even then it doesn’t hold up multiple gens.
SR uses a MPEG-4 compression which which is inter-frame. Thus it is a lot more efficient than ProRes and other NLE-friendly intra-frame codecs.

I am running an 8 core with 8gb ram. How do I upload video to the COW?

You have to host it on a server/website and then write a line of code to embed it. Luckily you can copy and past the code from this article and change what you need. Or provide the link to that website.
Or set up a yousendit account and provide a link.

Hey,
I just went to export a 10 second self contained quicktime for you guys and it doesn’t do it in quicktime player…yet the same exact clip wont play back correctly in FCP….
any ideas?

Are you sure your system is setup properly? Proper easy setup, right video out setting?
What kind of drives and hardware do you have?

Jeremy,
I have the proper easy set up, and I am using a Kona LHe for video out. My Mac Pro is being served by a Facilis 8xs through fibre cable…it is only this codec in FCP that is giving me this issue. When I transcode it to uncompressed, it will play back fine.
Any thoughts?
