It's a little vague at this point but I think the keys are:

* For reuse, we want something that's *super-easy* to consume in existing pro, prosumer and consumer editing tools

* Obviously staying out of the patented arena (ProRes ??, AVC-Intra, etc) is a plus
* Consuming those formats where ffmpeg takes them is probably ok (but patents??????)

* For archival, we may want something higher quality or less convenient, as long as we can convert with easy tools

Lossless is probably not necessary, but near-lossless that's good enough for reediting is strongly desired.

Yeah I'd recommend simple MJPEG/PCM for now as something that "works as-is" with some limitations[1], but investing a little time and effort on things like MOX or JPEG2000-in-MXF / Dirac-in-MXF might be wise for the future.

[1] no 4:2:2, 4:4:4, or alpha; highest qual settings are still much lower bandwidth and presumably quality than the ProRes generation. Probably still suitable for many purposes though.

I'm joining the list a little late and in the middle of this discussion, but have there been requirements defined and if so, can someone point me to them?  What are the guidelines that make one existing option better than another?  Are looking for lossless-only sources?  What is the target material, because not all material uploaded IS lossless.  I am sure these have been answered, but I am not yet aware of them.

Thanks!
