This seems like a good solution to me - leave QuickTime out of it all together. And there are many other MP4 players to choose from in addition to VLC.

Another movie format I've been checking out is WebM, an open source format sponsored by Google. It will soon support 4:4:4, alpha channel, depth channel, and maybe 10-bit. Seems like it could be a good open source replacement for ProRes if it gets wider adoption. You can currently play WebM directly in Firefox, Chrome, VLC, and others.

They have a companion still image format, WebP, which supports lossless compression too. Unfortunately, the movie format doesn't currently do lossless.

Yes, Googles VP9 looks very interesting, and so does the new ORBX.js codec that Mozilla and the Otoy guys have been developing:

Both of them claim about the same compression/quality as h.265 (HEVC), but both don't have the same license "problems" as h.264 have and h.265 will have. So maybe the future standard codec wont be h.265 as many predict, but maybe the future looks more bright.... or messy... depending on how you look at it :-)
