Post subject:  Hi-Vision (& maybe Squeeze LD) captures

Just recently I have acquired a "Blackmagic Intensity Pro" video capture card, capable of accepting an analog-component high-definition input. I'm still struggling to make it work, but I have had at least a little success so far, with grabbing a still frame. So this is the test pattern from "The Test Disk", captured via Sony HIL-C2EX and MSC-3000.

This card could acquire native MUSE 1080+i signal at high bitrate?

Yes, if I could get it to work. But it consistently crashes my computer (even though I carefully selected a motherboard listed as compatible), so I'm going to try to return it to the seller. Anytime you have to resynchronize your RAID array, something is wrong.

This is an amazing capture card, but it can be picky. Haven't tried high-definition analog capture with it since I don't own a MUSE decoder, yet. Although it does perform extremely well with regular capture. So far laserdisc is the only analog source I've been able to capture with it. VHS has a lot of blackouts for some reason and old video game consoles and computers is out of the question. Had issues with the software, it would crash if I selected the wrong capture source and get jinxed until I completely removed the program and any stored settings. I use VirtualDub to capture the raw video and then process it with AviSynth. At least the blackout thing is a known problem, but BlackMagic Design does nothing about it.

Hope you manage to sort things out, would be cool to see some captured footage.

If you want to do VHS, I'd suggest running it through a frame-synchronizer first, to clean up the timing.
Why it was glitching (recognizing only about one frame out of 3) on MUSE I don't know, because there is an option specifically for 1080160 (as opposed to 59.94), which is correct for NHK Hi-Vision.
