Avid workflow for Canon 5d Footage
Hi All,
I have been fishing around for existing posts that will answer my questions regarding a 5d Workflow for avid, but questions still abound. In the past, my experience with 5d footage has been misc. broll and “beauty/hero” shots that do not need grouping. However, this current project will require that some of the canon footage be grouped in with my tape footage. In the past, I would simply import clips at DNX220, string out clips by tape name, layoff to tape and use the tape as my source.
This time around, rather than laying the DNX220 to tape, I have been running some test with offline (20:1) and online (DNX220) media files to see if there are any relinking issues… which there are. Clips are relinking to different and wrong media.
If anyone has any suggestions on a solid workflow that I can utilize, it would be greatly appreciated.
Thanks!!

The 5D and 7D do not have time code, so doing an offline/online is treacherous, to say the least.
Just use AMA to open the clips, then transcode to DNX 220 (or 145…220 might be overkill for it). Throw storage at it and work at online quality.

There are also programs out there that will add the time of day shoot timecode to the canon files. (the information is always there, its just a matter of making it legible to the edit programs.)
Once you have individual timecodes for clips, it will make it easier to relink. check out Grinder and QTChange.
Run the clips through one of these before you do anything else, and it is (almost) like laying to tape.

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

but then again… considering I’m not even able to delete the double accidental post above… maybe it’s just me not working, huh?
cheers

Ha! I appreciate the thoughts. I ended up just importing at DNX220 and laying off to tape and will use the tapes as the reference now instead. Bit of a time consuming work around, but I cannot afford the possibility of relinking issues by keeping it tapeless when we go to online. Canon footage looks amazing, but not quite ready for smooth multi cam use, in my opinion. And my opinion, has been flawed, or lets say uninformed, on more than one occasion.
