>>>>>>>>> "Fluid video recordings without delays or distortions during live

>>>>>>>>> Transform high-quality video cameras into a high-resolution USB web camera".
>>>>>>>>>
>>>>>>>>> I have done a quick, first test using my Sony HDR-FX7E camera.

>>>>>>>>> tape 1440x1080, 50i25fps, 4:2:0 and MP2 stereo audio. Currently it's

>>>>>>>>>
>>>>>>>>> But according to Steve Mullen's V1 and FX7 handbook (not mentioned
>>>>>>>>> in the manual):
>>>>>>>>>
>>>>>>>>> 1. When the camera is operating, the EIP (Enhanced Image
>>>>>>>>> Processor) generates uncompressed 1440x1080i with a 4:2:2 color space. Digital
>>>>>>>>> 4:2:2 data are output via the HDMI port while 4:2:2 analog is output via
>>>>>>>>> component-out. Therefore, you can record 4:2:2 live HD video from the
>>>>>>>>> camera without MPEG-2 compression. V1 and FX7 provide an HDMI output port
>>>>>>>>> that carries uncompressed 4:2:2, 8-bit, digital video plus dual-channel,
>>>>>>>>> PCM, 16-bit, 48kHz audio When the camera is running.
>>>>>>>>>
>>>>>>>>> 2. If you are playing a 1080i50 or 1080i60 HDV tape. The 4:2:0
>>>>>>>>> MPEG-2 is decoded and chroma up-scaled to a 4:2:2. The HDMI
>>>>>>>>> chip downscales 1440 to 1280 while it up-scales 540 to 720. The
>>>>>>>>> result is 720p50 or 720p60, which is output via HDMI.
>>>>>>>>>
>>>>>>>>> That is, I have tested section 1 now, but see now that I didn't
>>>>>>>>> test 1440x1080 resolution. The only resolution I got to work at 25 fps was
>>>>>>>>> 720x576 (SD), while HD 1280x720 and FHD 1920x1080 were set down to 10 fps
