Capture with Vdub and Intensity Pro

I tried capturing uncompressed in VirtualDub with the BlackMagic Intensity Pro (HDMI).
Everything works fine, except without a Raid array, I can't maintain the 120 megabyte rate for very long.

So tried to capture with Huffy, but it doesn't show up in the compression list.
I then installed the Huffy with the CCESP Patch v0.2.5
It worked fine.

Or so I thought until I checked the color.
I output color bars from my Canon HF S10 video camera.
The output format is 1920 x 1080.

Please follow along here: http://www.etfinder.net/capturepics/


The intensity Pro outputs yuv 16 to 235, why do I need to convert to anything to avoid the skewed color. Why can't I just capture what it gives to Huffy without a filter?

Does anyone have any ideas?


Thanks,

Chris

You can simply take the SDHC card from Canon and copy its content on the PC (I think Canon has a software helping you to join back the files).

Or you'd like a live capture?

The point is to capture live through HDMI and avoid the loss of quality that happens when the video is compressed inside the camera. With compression, you lose your 4:2:2 color and get 4:2:0 color, and you also get compression artifacts. By capturing live you get a much better image.

You're right about loosing the quality, however there are few hardware solutions to play natively 4:2:2 (as BD is 4:2:0 AFAIK). You probably want to edit them as 4:2.2 then downsample them to 4:2:0, which makes sense.

No idea for the colorspace...
