Is there another way to get to MXF? Indeed the DNxHD encoded files I have made require re-rendering. The files I encoded with FFMpeg import into Avid (which re-renders them), but then crash when I press 'L' (forward/play track). No audio tracks are imported either in avid. Just "V1" without A1 or A2. I've encoded with and without audio in FFMpeg (-an), and get the same result.

I'm trying to find a way to get 1080i30fps or 720p24fps into the highest DNxHD bitrate files and import them into Avid without re-rendering so I can create the files in batch while I sleep.

BTW, FFMpeg lists mxf as a "format", but I'm not sure if that is import only or if it's not will support the criteria I need. I've asked around on other sites, this doesn't seem to be a common approach to what I'm wanting to do. I'm new, so this might be the wrong path, but it seems correct.

im building on such a AVC intermediate workflow (10 Generations) currently as my tests with Cineform and Canopus HQ where destructing both but i didn't test DNXHD yet

PS: My tests where done in the 80 mbit range reaching 51 dB for 1440x1080 30p (tough with compresed Mpeg-2 source)
Results= http://cruncher.mufflastig.com/hdtv/hdv/intermediate/
Did you use highiest HQ settings or the one which gives about 100Mbit bitrate?
If you have your results up to 4 digits than you should have xx.3450 not xx.345 - heheheehe

Hmmm....Canopus HQ is great codec- extreamly fast and quality is also very good. Cineform is better (depends on quality settings), but slower. I'm supprised (or maybe not), that AVC-I is so good, but of course not as fast as 2 others.
AVC-I in Edius works briliantly- RT playback with no problems even with few tracks. Very fast encoding also (2x faster than RT for 1920x1080 60i, with 95% on 8 cores machine)- Edius is one of the best multithreaded application I've seen.

DNxHD is not going to be better than Cineform at the same bitrate, maybe slightly better than Canopus HQ, but way slower on Windows.

Any advancements in bringing ProRes support to FFMPEG? It's been 2 years

x264 can achieve ~2x realtime with 1080p50 on a q6600 ~100fps thats only 4 cores

These are 2 different porducts- h264 is not even a product- just a "core".
Did you test I frames only at 100Mbit?
