Blackmagic Design Developement recently replied me that Media Express
can capture uncompressed & MJPEG on linux.
My other question to them was about the new Intensity Shuttle, as an
flexible A/V video converter and capture box for powerful laptops/mobile
workstations. I wondered why only Windows is said to be supported, when
Linux kernel 2.6.31 was the first OS that got USB 3.0 support.

They replied: Despite getting in early with basic USB3, Linux doesn't
yet support USB3 isochronous
transfers which are required to stream at high bandwidth.
Does somebody know if 'USB3 isochronous transfers' is included in the
latest kernel 2.6.34?
Thanks,

Using BM cards, If you don't need 4:2:2, just convert the input video to planar
yuv 4:2:0 at capture time, in realtime using ffmpeg.
I posted some time ago a capture software for BM I did.
The blackmagic card is not HDV it's for uncompressed full 2k capture.
I have had no luck getting bm output into cinelerra. I belive the
problem has to do with planar vs. non planar and colorspace. it's not
YUV 4:2:2. Not sure. If anyone wants to try I'll post some footage.
