I guess the list is fine, but direct mail works, too.

I guess direct support for the video streams would be a little too special, but the extracted DNGs are definitely in scope. > A sample .dng extracted from the camera raw video output: > https://dl.dropboxusercontent.com/u/74780302/000000.dng , although > Rawtherapee and UFRaw will open theses .dng's DT crashes, I'm not really > surprised as I'm sure the .dngs are missing some fundamental header info > that trips DT up. > > Basically the 3rd party firmware outputs 14 bit raw bayer data packaged in > a ' .RAW ' container as a sequence of frames. > > The ' .RAW ' packaged file requires a simple C coded tool to open the > contents and write them to a sequence of ' .dngs '.

Thanks for the sample file, I already wanted to install ML on my 5d3 but I only have 8 GB cards which are a little small for this. :) I will definitely have a look into this and if it's possible to directly support the sequences. (Note to self: we would probably need a new column in the images table that stores an offset into the file or something like that and then import every frame with a different offset as an image or something like that) > Thanks to all DT developers for such a great tool and best wishes. On a mildly related note, today I pushed a new feature to git that might be interesting for video workflows: a new waveform histogram mode. Next step will be a lift/gamma/gain module, I am currently trying to figure out how to do the UI. Once these are done it should be possible to color grade your footage with a tool that many video editors already offer. :) Tobias PS: I am forwarding this mail to the devel list, I guess having input from others can help, so we should move the discussion to the public.
