Did a really small video with a friend this Weekend with 1280x720, 24fps.
It really does not Showcase the RAW abilities too well, but well ist something

I recorded a lot more and will edit and upload that too, as soon as I get to it.
But my short tests (Nightly build 1st June, 31.05 RAW module) had the following results:
960x544 constant recording, no dropped Frames 'til about 7400 Frames.
1280x720 about 13 seconds recording times.
All in all the Image Quality is really awesome and the post flexibility is incredible. But the post workflow is a nightmare (maybe only cause I used the 0.9 Version of Raw2DNG, where you have to drop every RAW file in there at once)...but still, this is incredible!
One question though: I can only record cropped, so I have the window in there which would equal the 1280x720 Pixels. Is there any way to record the whole imageframe?
Thanks a lot to the whole ML Team and all other devs!
