We use mjpeg for the higher quality movs and h264 for lossy stuff and sg
uploads...
All done via ffmpeg externally as Nathan already suggested.
After looking into this we also went for those, as RV does not have
problems with the both of them, dnxhds or prores needs some compiling
for rv to play it back....
As rv is the only "frame accurate/scrubbing " capable mov player under
linux, with audio this was/is important.
And they produced almost no colorshifts.
we use the static ffmpeg builds from here.
http://ffmpeg.gusari.org/static/64bit/
here are the ffmpeg command lines:
the soundstuff is a bit outdated
*./ffmpeg -start_number 1001 -r 24 -i "imageseq.%04d.ext" -i
"soundfile.wav" -vcodec mjpeg -qscale 1 -r 24 -pix_fmt yuv420p -vf
"scale=trunc((a*oh)/2)*2:936,setsar=1" -strict experimental -acodec
pcm_s16le -ar 44100 -ac 2 -y /output.mov
*
*./ffmpeg -start_number 1001 -r 24 -i "imageseq.%04d.ext" -i
"soundfile.wav" -vcodec libx264 -pix_fmt yuv420p -r 24 -vf
"scale=trunc((a*oh)/2)*2:720,setsar=1"-g 30 -b:v 2500k -vprofile high
-bf 0 -strict experimental -acodec aac -ab 160k -ar 44100 -ac 2 -y
/output.mp4

For some unknown reason, Nuke's ffmpegWriter doesn't support mjpeg,
which would probably be your best bet (it's identical to Photo JPEG
for all intents and purposes, and is recognized as such on OSX).
MotionJPEG (which I think Nuke does support) and mjpeg are *not* the
same though... that's an easy mistake to make.
In other words, you're still probably better off post-converting things.

If I recall correctly h264 showed up in my lists of available codecs.
I havn't compiled it myself, maybe ffmpeg included it because some
other application installed that codec?
Ubuntu 12.04 is what I'm using in this case.

I don't think our ffmpeg is compiled against x264 as it requires a
licensing fee for commercial use so I don't think there are any h264
codecs in our ffmpeg writer. Unfortunately I'm on a mac right this
sec so I can't check as there are lots of codecs in there.

Using the default in nuke does usually not cause a problem with
playback. Otherwise I usually go for h264 as a codec for mov
containers.
