It would be to nice for 5d2 users to have a raw file that is smaller than 1920x1080, being put on a 1920x1080 canvas before rendering to Prores. And then having a standard format with some black borders for editing.
Before having a 5d3, this was an extra step I needed to do before importing in final cut and having all material in the same 1920x1080 format.
Then, doing an online edit, say in 2:35 aspect ratio, you crop of the edges for final delivery. Or in my case, you can easily mix with material shot in 1920x1080, but framed for 2:35 (and being able to reframe a bit or to deliver 16:9 should the client need it).
Oh, and at least a daylight and tungsten preset.
Currently, my workflow relies on Ginger HDR, but it looks like the programmer will not be adding support for MLV. I use it to create proxies and then when doing an online, I use RawMagic to only convert the needed files to DNG sequences.
Not having DNG's of everything saves me a lot of space.
Is timecode possible? I use the creation date of the raw file now as timecode, but it's not very accurate.
I wouldn't mind paying for a solid solution, as long as you're allowed to run it on several boxes. But please don't be offended by this...
