The HD restriction is also a turn-off for me.
    Maybe a bit strong sure, but so is saying that the codec is a bad choice because it screws up colours/gamma, etc, when in fact, it doesn't. I guess my tone was strong so as to make an impression, but for the good. Sorry if I offended you.

    I had intended to edit native r3d. However, when I make changes in RedCineX, these changes are not accurately interpreted by Vegas. My r3d clips in Vegas look different to the grade that I've done in RedCineX, and I can't deal with that, and it's a mojoy problem with Vegas as far as I'm concerned.

    It's worth testing stuff like this, so you know for sure. Listening to us on here to make a decision like that is not the best move IMHO. Sure it might save you time, but why not install both codecs and compare the two? I did that and felt better with DNxHD over cineform. Paul makes a good point about HD res restrictions though.

    As for red cine x changes not displaying correctly in Vegas, it's because of two possible reasons. One, you are grading in red cine using a gamma space that is not supported in Vegas (maybe red gamma 3 for example) and two, bit depth. If both of those match, and the colour space is the same (rgb, not yuv) then the changes will look the same.

    True! Thanks for the clarification :) I wish QuickTime would die.... And same goes for codecs that are only truly supported on one system (lookong at you ProRes). It's almost 2014, with 6k video, how many stops of dynamic range, affordable media and lenses.....but wait....let's keep bending over for an ancient codec that isn't cross platform? And while I'm ranting.... Batteries! When will they get smaller....?

    So, I downloaded the GoPro software, and now I'm seeing the 'Go-Pro CineForm Codec' under Quicktime.

    Is this the correct CineForm codec for my Cineform vs DNxHD test?

    Will.

    Also, I don't seem to be able to output DNxHD at a 2.40:1 aspect ratio. The only options are 720 and 1080 16x9.

    Am I able to transcode to widescreen in DNxHD?

    DNxHD is a 16:9 only codec for 720 and 1080 formats. Any other ratio will be pillar/letterboxed within that aspect ratio.
