I have never used my IP4K for capturing before, but since I am in the spirit of playing around with capture devices and comparing them, I thought I would upload a quick comparison.
This is a follow up to an earlier thread:
1. Canopus ADVC-300 to DV-AVI 4:1:1I had read somewhere people poo-pooing the IP4K as an NTSC capture device. TBH, I think it does a great job. And unlike the I-O Data device, you can adjust the gain. Speaking of which, the IP4K gain needs to be reduced slightly, but I just used default settings.
2. I-O Data GV-USB2 to lossless YUY2 4:2:2 which I transcoded (losslessly) to UYVY 4:2:2
3. Blackmagic Design Intensity Pro 4K to lossless UYVY 4:2:2

I processed hundreds of hours through my trusty ADVC110, but I've moved on to lossless capture. There is a kind of pastel, bleeding quality to DV that my eye, trained by those hundreds of hours, no longer tolerates when converting a high-quality NTSC source.
Vaporeon800 has a thread about capturing VHS with the Intensity Pro 4K which he created not long after it came out. He said it only had a 2D comb filter, which made it less than ideal for capturing composite video sources, that its built-in TBC was not very effective, and that the device drivers were buggy. That being said, he was not completely dissatisfied with it for S-Video capture, although he saw interference patterns with every S-Video cable he tried. Maybe the buggy drivers have been fixed, but the other problems still remain.

I did not have any driver issues with the IP4K. BMD is on version 10.7 now, so whatever issues vaporeon had back then are very likely resolved. With that said I did notice that they only support Win7 and up. So anyone running XP is out of luck. But honestly I would not recommend buying it for capturing. I highly recommend it as one of the cheapest devices for color managed workflow. To me the capture capability is just icing on the cake.
Your IP4K sample has similar cropping + letterboxing as my captures with the card. Thanks for providing this confirmation. Yours actually has 4+3 empty "video black" lines rather than 3+3.
No one on Blackmagic's forum confirmed or denied this error, and their Support was ultimately useless. The person who responded was under the impression that analog video, even from a DVD player, is inherently unstable. Meanwhile, someone else who works for them apparently believes that US LaserDisc players put out some exotic format rather than standard video.
I guess the combination of them being Australian (PAL) and not caring about SD analog explains why they never noticed that their card can't capture a proper 486i video.
