2 black frames upon capture

On my latest project, I captured using Vegas's capture rather than HDVSplit in order to get better Vegas timeline preview efficiency. I have noticed that in the captured clips, there are a couple of instances where there are sets of two black frames in the captured footage. In the past I have always captured HDV with HDVSplit. and while I have had problems with the "two black frame bug" during renders, but this is the first time I've ever seen it in the captured footage. I am in the process of recapturing everything with HDVSplit to see if I this will avoid the problem.

Usually I just use Cineform to avoid all these problems, but in this case, I have so much footage (16 tapes in all) that I want to use the more compact m2t method at least until I get a rough edit.

Has anyone else run into the 2 black frame bug on capture?

I have encountered the black frame problem, but on captures that were fine. The black frames did not appear until I start navigating in the TL. The captured files themselves don't contain the black frames (at least mine don't). The problem started with 7.0 and has been with us for several updates. Getting rid of this annoying glitch is my number one priority for 8.0.

That is what is so wierd. This is the first time I've seen the 2 black frames on capture. This should really be fixed in 7f rather than waiting for 8.0. I feel like I've been working wtih a beta quality version long enough.!

Yes, I would also like to see this fixed in 7.0f, but, alas, I'm no longer holding my breath. And, like I said, I've yet to see the black frames in captured files. BTW did you officially notify Sony about this?

I am still recapturing in HDVSplit. If the same clips don't have the sets of two black frames, I'll have something to report.

I don't THINK it's related to the capture program, but who knows...

On my latest project, I'll be using HDVSplit v.77 rather than v.75 that I used last fall.

I wish Sony would at least acknowledge that this is an issue for many of us.

I used Vegas capture for my last project instead of Neo and some of my clips were split in the middle of a performance ( wrong! ) and left a gap in the audio as well. I didn't get a visible black frame but a gap which of course reads as black when previewing.

Is this what you all mean by the "black frame" bug?

It sucks! and is a total pain to "patch"....
I got these in each of 6 tapes using the Vegas HDV capture.

I sent my 2-black-frame bug report to Sony on June 1 2007. They have heard about it, but as of June '07 had apparently never been able to reproduce it themselves. They asked if I could send an example file, but gnerally when I've seen it, the clip is too big to transfer and anyway it seems to be hardware-dependent at least in my case. Also, setting Options/Preferences/Video Tab/"Dynamic Ram Preview" to 0 MB and restarting Vegas sometimes (but not always) fixes the bug.

Reply from Matt K. at Sony (Madison WI) on 06/26/2007:
"[...] Since we do not reproduce this here, this becomes a difficult issue to test... So I am limited in being able to pin down what the problem is and cannot offer a concrete fix at the moment. However, we are looking at this issue and will examine it more closely going forward."

I recaptured eight tapes with HDVSplit .77 with the preview turned off. Amazingly, there was not one single error and all the clips were interpeted by Sony as having the correct preview efficient codec. This was with the same standard Sony Mini-DV tapes that gave me several errors per tape using the Vegas capture. It was my first capture with the latest version of HDVSplit and they seem to have got it right this time!
