Canon 5D Mark II footage Workflow?
Does anyone know the best way to import and edit this camera’s HD footage? This camera shoots 1080p at true 30fps in Quicktime H.264 format. I’m running Avid v.3.1.2. In creating a new project, the settings do not offer these exact specs, only 23.976, 24, & 25fps for 1080p. Footage pulled into 23.98 naturally looks stuttery.
Any insight into this dilemma would be appreciated.

Import the .mov files and transcode them to DNxHD. There should be no degredation, and the Avid codec will stand up to layers, effects, playback, etc. much better than other options.

Hey Joe
Thanks for the quick response, but it does not address my frame rate problem. I agree the DNX_HD wrapper works wonders but this footage is 1080p 30fps. Avid doesn’t give you an option to set up a new project as 1080p/30fps, thus the Canon footage is wonky in any other 1080p project.Still stumped in stinky town.

You have to go into the console, and enter
IgnoreQTrate = True
this will force Avid to import a frame as a frame.
(effectively slowing it down to 29.97)
Now this works great, but your audio will be out of sync.
To compensate for that, export the audio as wave files, and set a 48.048 sample rate on it. (there are free tools to do so)Another option would be to use my QTchange application.
This can batch add timecode to the clips, and do a speed change.
The timecode is nice to have, but won’t come across on your sytem.
(qt tc on import / export came to MC on version 4)
Michael Philips got the speed change to work with Avid, but i don’t trust it very well. (and it works destructive)
So if you do toy with it, work on copies of the original.Bouke

Sorry I have been out of pocket…
See Bouke’s post. We just had the same discussion on the Avid-L2 with Bouke and Michael Phillips chiming in, and all agreed that the videotoolshed solutions are tried and true.
I trust Avid will have its own solution via AMA at some point, but for now, Vahl-hala is only a third-party application away…

CORRECTION.
The Canon records audio at 44.1,
So first upsample to 48K, THEN change the SR to 48048Bouke

Hey Guys
Thank you so much for the detailed response. I can’t wait to try these solutions. This is why I love the Cow.
Much appreciated!!!! -
Hey Bouke
Where do I access console to enter IgnoreQTrate = True ?
Thanks -
Hit Ctrl+6 on a PC or Cmd+6 on a Mac and it will open the console. Type it in the little box at the bottom and hit Enter.

Hello there.
This is Giulio from italy, sitting in front of Avid MC 3.0.5 (no AMA).
Importing a native h264 CanonMarkII file.
Importing it both in 1:1 and/or 1:1x codec.
Importing it both in RGB and/or RGB “dither colors”.
Immediately re-exporting the file from source into either 1:1 or 1:1x or uncompressed or no-compression(none) mov files.The result should be absolutely NO difference between this export and the original file, right?
lossles in.
lossless out.
Truth is that the exported file has noticeable differences:
1) output file color is poorer… meaning the output file is desaturated. Specially on reds.
2) the output is slightly darker maybe 4/5% than the original, let’s say…
3) I can definitely see compressionShould we consider I did something wrong which is possible even if I’ve been an avid editor for 10 years, now…
Or should we finally state once and forever that avid 1:1
IS NOT LOSSLES AT ALL?Another consideration:
Canon MarkII files run around 45 mb/s.
Importing them into a dnxhd 120 codec should give them range enough (dnxhd120 is 120 mb/s which is almost 3 times what needed to deal the native canon bitrate…)
But once exported… into uncompressed quicktime… the file is soooo damn shitty compaired to the original.Please someone help me
