1T-TBC - How to determine version

[lordsmurf]

any additional device in the chain introduces a neglettable or significant image alteration

This isn't necessarily true. This is the concept of "transparency". It also leads into a discussion about proper alterations, such as legalizing. You don't necessarily want unaltered if the unaltered is bad.

As I often write, there are factors. Which is why I wrote several posts ago that simple A/B comparisons are often an incomplete summation. A/B can be a very low-knowledge way to approach complex topics, if/when done improperly. In this thread, A/B was just comparing variables without a constant. We have no idea what is the "proper" image recording, so false assumptions are/were made that one is "darker" (or the other "lighter").

What I see is either:
- Over-contrast in the "without TBC", and typical muddy VHS dark in the "with TBC". That suggests timing issues that have interfered with luma/chroma values (and that happens).
- Wrong/drifted proc amp settings on this exact TBC, leading to +1/+2 offset on contrast settings.

If you guys want to keep your TBC always on for convenience of usage, and do not care about potential loss of quality,

But the inverse is also true. Not having TBC also leads to "potential loss of quality", and that's actually more common than the inverse.

However, the second and major point in this topic, was the statement that "comparing videos is useless", which, as a man of science, I can't tolerate,

Simple A/B comparisons can be quite misleading, thus worthless. That's science too!

especially with the false motivations brought forward as a counterpoint.

What motivation? Are you strawman insisting that because I sometimes refurb+sell TBCs, my information is somehow invalid. Okay, what about the two decades prior, where I gave the same advice, and sold nothing (because refurb was not needed, the gear was sold new at B&H/etc). Hmmm?

Not at all.

It is true that you have a conflict of interest big like a house, but I don't care, nor I deny some (some) aspects of the capture process where we agree (I just point out to others that when you write that some modern cards are inferior to the Pinnacle USB 710 you sell is false; just as an example).

I referred to your desparate attempt to invalidate a comparison with silliness like "It's not as easy as random items cobbled together, and then compare it pseudo-scientifically" or "Pro users easily spot this nonsense, but casual/amateur users are fooled (and wrongly led to believe that methodology is correct)".

Next time think twice before writing.

The Pinnacle cards in the marketplace are nice. There was actually someone recently on dfaq that really like his and he has had his pick of basically any blackmagic gear he wants for a while because he’s friends with someone that works for Blackmagic. I guess that really shouldn’t be a surprise since Blackmagic isn’t suggested by here or dfaq. https://www.digitalfaq.com/forum/video-capture/15269-vhs-worth-capture.html

You are definitely the most outspoken proponent of the newer cards. What are your conclusions about the newer cards being on par with the Pinnacle cards or the ATI AIW line based on? I’m not trying to be rude in just wondering out of curiosity.
