5D to FCP conversion issues
we are transcoding a bunch of footage for a doc shot on the 5D. our plan was to go to ProRes LT but we have been getting a weird gamma shift and some issues with the saturation. the machine we first tried this on is running snow leopard and the latest quicktime and final cut studio 3. we took the original test clip and converted clips to a machine that is running leopard and quicktime 7.6.2 and the differences between the original clip and the test clips were less noticeable. has anyone noticed this ?

OK, how are you transcoding?
-
well our original route was through MPEG Streamclip but when our editor noticed the gamma shift he started trying Compressor but Compressor was so crushingly slow that we gave up and started this posting process. i am not sure if he got clips out of Compressor or not to compare with MPEG Streamclip.

You should try the Canon Log and Transfer PlugIn.

i have never used it – it transcodes to other codecs too ?
the only problem with that is we have 2 TB of footage already in on the drives for this project.

Yeah, but if it’s transcoded improperly, is it any good?
the Canon plugin is easy. It allows transcoding to ProRes of all flavors.
and
it’s free.

i hear you but ( forgive my lack of knowledge about it ) can we take clips that were pulled directly off the SD cards and onto drives, and still run them through the Canon tool ?
-
You need the full card structure, not just the .movs.

thanks for your help on this jeremy. i guess we are a bit hooped then for this method as the cards have been wiped dozens of times since we captured the first footage. great for next time though.

Yes, it’s convenient.
You don’t have to make the DMGs as Canon suggests, you can simply make a new folder per SD card and drag and drop the entire contents in to that folder. Also, look in to shotput pro to automate and verify this process.
Do you still have the orig h264s at least?
How do you know there’s a gamma shift, i.e. how are you monitoring?

DUDE! You didn’t back up the cards? You just imported and then wiped them? Do you capture from tape and then record over it again? Sorry, that was a poor choice to make. You MUST back up the cards, the original card structure. To a hard drive. This is your master tape that you then import from and work with.
What happens if you lose your media drive? All the media will be gone. What if you imported wrong and need to redo things? Oh, yeah…that’s what happened now.
Now…where are you judging this gamma shift? If you don’t have the original files, what are you comparing with? What you saw on the LCD display? That’ll be different. And when you convert from one codec to another, there will be a slight shift too. But all you need to do is color correct it after you are done editing…that’s normal.
The Canon plugin is a good choice. As is Magic Bullet Grinder (https://www.redgiantsoftware.com). That software uses ALL the processors to speed up the process. Great app.
Well, you can’t convert what you already have converted…gotta live with that. In the future, back up and try the other options.
