Hi Rafael, This is real interesting to hear. I think I have the possibility to output uncompressed 1440x1080i50 as 4:2:2 digital data from my Sony FX7E camera/EIP via HDMI. Therefore also I plan to buy a BM Intensity Pro, and have a handful related questions:
Q1 Are there other hardware requirements (CPU, RAM etc) to "work with" (capture, playback, edit, encode, decode) uncompressed 1080i50 YCbCr 4:2:2 (UYVY) video? Q2 Any especial BM driver setup on Linux to get this to work? What more features will become available with the next BM Media Express 2.0 software on Linux? Q3 To compare with compressed 1080i50 HDV (1440x1080, 4:2:0, 25Mbit/s) which like DV25 needs disk space about 13GB/hour included audio, what disk space pr hour is required for uncompressed 1440x1080i50 YCbCr 4:2:2 (UYVY)? Q4 Is uncompressed 1440x1080i50 YCbCr 4:2:2 (UYVY) a suitable or even native format to edit/render in Cinelerra, and better than using compressed 1080i50 HDV? Q5 Encoding uncompressed 1440x1080i50 YCbCr 4:2:2 (UYVY) with the more effective x264 compression at a high data rate up to max 40 Mbit/s for Blu-Ray disks, I expect this should make it possible to get a considerable higher video quality (especial colors) distribution format than possible from usual HDV (M2T) (?)
