4 different IODATA GV-USB2's tested with samples. Line-TBC-Like-Activity?

Oh, the delicious irony. @Sharc, with his detailed analysis over recent times, has done more than @Lollo or I to promote the GV-USB2 as a good, modern digitiser.

To clarify: These "wiggle comparison tests" alone do not disqualify the GV-USB2 models at all. At least your clips also confirm that the GV-USB2 captures well into the full (.....254) luma range and do not hard clip at Y=235

Enough drama. Crack it open and show us if it still contains the Techwell TW9910 chip, or something different. If it's the same, then we're all just arguing about minor performance variations in the same hardware.

TW9910 produced by Techwell, Renesas or Intersil ....... oh well .....

- GV-USB2 in AmaRecTV does not properly report insert/dropped frames. That's because the internal mechanics of broadcast software is about continuity, not signal integrity. Dropping/inserting frames is an expected action of broadcast/streaming software. While AmaRecTV does some reporting, the exact reporting done, and why, is not clearly understood by anyone.

AmarecTV doesn't seem to report dropped frames correctly with any capture device, so it shouldn't even be used for testing.

What does this have to do with the topic of this thread? Why do so many threads derail badly and end up with a sometimes childish debate of Vdub version xy vs AmarecTV? Everyone make his own experience. Finish.

False.

Since the topic has been raised, I'm not interested in all the VirtualDub vs AmarecTV wars. I correct the claim that AmarecTV drops frames with I-O Data -- apparently, it drops with everything. That's why I ran my own tests, which no one can refute :P (being convinced that AmarecTV will be better)

That claim is from lordsmurf in post #19 is from that charlatan of lordsmurf, who does not know what is talking about, nor provide any fact about it.

False.

Not confirmed by anyone, while tests from others including myself show the opposite.

[rgr]

Open to other suggestions for specific tests as well as it might be a while before I get to these.

I suggest numbering all the frames. This way you'll know if 10,000 frames will actually result in 10,000 frames.
