I was scanning through the Post & Surround part of the DUC and found a post about mp4 codec recommendation question from Sparky3000…
Hey all,
Forgive the question as I’m sure it’s somewhere here, though I find me efforts with the search function at the DUC usually don’t go well. (It’s me, not the engine, I’m sure.
) Essentially, I’ve been working with DV vid for all of my mixes. (Longform shows.) I’m not getting stuff from out of town clients and converting from MP4 back to DV with Streamclip. Works OK, but seems to soften sync even more. I’ve tried importing the MP4 directly, but it’s always sluggish and choppy. My system runs flawlessly with DV. Any recommendations of a spec for an MP4 delivery that might work without converting to DV, or is this an “it is what it is” situation? Thanks!

Although it is not mp4, try this: http://www.avid.com/US/industries/workflow/DNxHD-Codec Less taxing on cpu, good picture quality and less size.
Now if you follow this link then you will read…
Avid DNxHD is a revolutionary HD codec technology engineered to create mastering-quality HD media at dramatically reduced file sizes, shattering the barriers to real-time HD productivity, whether using local storage or in real-time collaborative workflows. Native HD camera compression formats are efficient, but simply aren’t engineered to maintain quality during complex post production effects processing. Uncompressed HD delivers superior image quality, but data rates and file sizes can stop a workflow dead in its tracks. Avid DNxHD delivers both efficiency and quality without compromises.
Key benefits
- Optimal mastering picture quality
- Minimal degradation over multiple generations
- Reduced storage requirements
- Enables real-time HD sharing and collaboration
- Improved multi-stream performance
- New Pro Tools 8 Workflow Improvement : The QuickTime HD codec can be exported much faster from Media Composer than other QT codecs, offers superior playback performance and picture quality in Pro Tools, and has reduced storage requirements.
Avid has also created a QuickTime HD codec that can be downloaded free of charge, for Mac OSX and Windows XP. With this codec, DNxHD media can be used seamlessly in QuickTime compliant applications such as Adobe After Effects or Apple Final Cut Pro. The Avid DNxHD codec allows additional flexibility on systems without having the Avid editing software installed to fit any type of workflow needed.

Seven radio producers – all based in the north of England – have joined forces to launch a new co-operative venture – ‘Radio Wizards’. It’s equally remarkable that their aim now is to work together on every kind of sound production... except radio!
"It’s taken over a year to get to this point," says ‘wizard’ Mike Thornton, "but now we’ve got a viable business plan, we’ve launched our website and we’re already starting to attract commissions. As a facilities provider we decided to facilitate this partnership and set them up with a web site to help kickstart this excellent partnership."

Sure! I have found this codec months ago, while I had some dvd projects. There were two equally bad possibilities.: 1. I got the picture in full hd (not really good for pro tools) 2. I got the picture in such a wrong quality that was really made me remember to the old vhs…
I started to search for viable options. As the sessions were so big that the machines were already had hard time handling them, I needed something which is good pic quality wise, but won’t tax my cpu so much. I made some tests (actually many tests) and have found this codec, which in my experience even less taxing than dv. Ever since I’m happy with it. And it works with virtually any transcoder software.

There has been a copule more posts on the thread and they have suggested asking for “photo jpeg” movies. There are ok in size to exchange via FTP and the run really smooth in PT. And for being a full frame instead of a field format it is rock solid, when it comes to sync.
