Awesome. Thanks for answering that.

HDMI does not support a 1440x1080 video format.
Good to know.

I am working on an update to our HDMI white paper with a compatibility chart for playback of Sony, Canon and JVC tapes in the variious camcorder and decks.
That would be very handy I'm sure.

I'll be honest I have zero experience with the Sheer codec. I just came across the website the other day and it claims on the homepage that you capture HD video using a two-disk SATA RAID, while encoding or decoding on the fly in real time. Do you have experience capturing with the Sheer? Did it not work for you? Seems like an inexpensive solution if it works.

Never used it for capture, only in AE for render when I was beta tester for the PC version a while back. I notice that they do now promote the codec for HD capture on a two drive array on their web site, as you say. That is exciting news given its lossless quality and price. It is hard to pin down the numbers but it seems to be a 55-60% space savings over uncompressed 4:2:2. This is still a fair sized chunk, but might now be the leading candidate for a home brew portable uncompressed capture PC. Which is what we all want isn't it?

I've done live SDI (raw) capture to the Sheer codec with a single SATA drive. I can only capture to the outer sectors of the disk for maybe up to 10 min. without dropping frames, but 2 drive SATA raid can definitely do it...and the quality is truly lossless compared to uncompressed.

Edit: btw, the codec is 50% off for a limited time right now. Well worth the $!
