is there any intuitive way that can do insert edits with no recompression in mov files? I am delivering Avid DNxHD mov files for broadcast and this would save me much time. Ahhh... and I am looking for something with graphical GUI.
I don't know anything about the Avid DNxHD codec, but if you have the codec installed and QuickTime Pro can open the files, I would use that to identify your edit points (GUI). Then, assuming FFMPEG can decode/encode that codec, you could use that to do the actual editing (no GUI).
Ultimately, if you went the Lossless H.264 route, you'd eventually have to encode it back to non-lossless so it could be read by other programs. I've found "-crf 18" is a great-looking libx264 encoding option.
In theory, you can chop up itra-frame codecs (such as DNxHD) and splice them together without re-encoding. Codecs with I-P-B frames can only get cut on an intra frame. (a.k.a. key frame) In practise it's more complicated than that since video frame timestamps have to be updated. So the ability to do that depends on the capability of the software. You should be able to do that with ffmpeg. However, if you're looking for something with a GUI, you're in the wrong place.
