Canopus ADVC as just Y/C separator?
Hi Lordsmurf,
I'm not sure in what thread to post it. Maybe it wouldn't even be legitimate thread. Anyway, as I mentioned in TBC thread I tried TBC AV Tool, but it didn't work well. However, I think I found something similar with my Philips card: the ability to select various recovery modes. I tried the capture yesterday from the VHS. I went 2 hours without any single dropped frame. The only problem now I have is capturing from composite sources as my Philps based tuner card's comb filter is simply the worst. But I was thinking to use Canopus ADVC-300 for just preview. Connect composite to ADVC, connect ADVC's S-Video to Philps Tuner card. Turn all the filters off other than Y/C separation. Canopus claims the preview undergoes ADC and then DAC, but in digital domain it doesn't compress to DV for preview. Do you know if I can use any test pattern to check whether I don't get compressed output for preview and that I don't get 4:1:1 color space for preview? The other option for me is to install 3d comb filter inside my LD player, but this maybe problematic. Thanks a lot. If you feel to post it in a thread, let me know what thread and I post it.

It would be a good additional test, but I'd still use VHS for testing, given how the ultimate end goal of the workflow is to convert videotapes (VHS, Betamax, Video8, etc). Several DVDs have hidden test patterns on the disc, such as Ice Age (a popular choice at Videohelp.com about 7 years ago, between a few of us). Avia (or Avia II) or any number of "test discs" are also good, for both test patterns and test clips.

My final goal workflow is to convert LaserDiscs outputting composite. But I understand that capturing has no test pattern to compare against. |
Laserdisc is close to S-VHS or Super Beta. ;)

Except that S-VHS has Y and C stored separately but LD not. :( That's the big problem. I got an email from Canopus Account Executive Distribution Sales North America today telling me that analog source is converted to DV first. Analog output is DV based. See different people at Canopus tell me different things. I guess I will have to have either my LD player tweaked to have 3d comb filter installed or to buy the middle man with 3d comb filter. Or try to use Compro Videomate Ultra that has NEC 3d comb filter.
