Workflow for VHS capture?

[latreche34]

Black Magic devices generally are good for the digital ingest, Beyond SDI and USB/PCIe, They do suck most of the time in the analog to digital conversion, I've tried them. For that, stick to consumer stuff or go for the big boys, Snell & Wilcox, Grass Valley, Ensemble Designs and some of the Ajas.

Thankyou, yes, correct, with a capture, over 90 min. it also stays in lipsync, consumer devices mess up the the limited and full range values + IRE, also because you can't set them in their software, in post you can correct the colors to correct some of these errors, but still there's some loss from that, but will be minimal using PAL source material.
(you can set the correct settings with DIP switches on the BMD analog to SDI converter)

What are you talking about? For recommended comsumer capture cards (ATI 600 USB, Pinnacle 710 USB, I-O Data GV-USB, Hauppauge USB-Live 2)
this is not true.

All capture cards allow to "digitally" set levels, brightness, constrast, etc. The few having internal analog procamp (such as Canopus RX) of course
features better handling avoiding gaps, banding and so on (defects, however, fixable in post-processing).

What are you talking about? This is not true. What you cannot recover is what you lost during capturing. But with a proper post-processing, there
is no loss

As latreche34 pointed out, better use BMD to capture from SDI (leaving the AtoD conversion to something else), not from analog.

No.

lollo2 laid it out in detail, but I just wanted to reinterate and reinforce what he wrote.
