Are you using a DV camcorder and saving as an NTSC-DV AVI (or PAL-DV if you're in Europe)?

Also, when does the out-of-sync occur? After you output from Screenblast, while you're previewing in Screenblast or as soon as you import the video?

Also, do you see the same out-of-sync when you preview your captured video in Windows Media Player? And, if not, do you see the out-of-sync problem in Windows Media Player when you export an AVI to your hard drive from Screenblast?

Just trying to figure out at what point the problem is occuring, Reg.

Hi!
Yes, I am using a Canon DV camcorder, and saving as an NTSC - avi format, nothing changed there.
The out-of-synch happens while viewing during capture, and then when previewing/editing in Screenblast (V3.0)
I erased the file last night in a fit of pique but will capture a section again. By the way, there were two tapes from this particular shoot, and the second was just as bad when captured even though only 15 minutes compared to the 57 minute Tape !
I think my capture preferences have got messed up.
Will capture a bit more and view in Media Player,
Thanks Grisetti,
Reg

More information:
Now, I cannot capture from the camcorder, the beast wants to go back to my old Dazzle device, won't recognize that the DV is plugged in. I haven't used that device for many months.
Ugh!

Sorry another bug crept in while you were dealing with this one, Reg. But don't panic. One thing about working with microprocessors is the problems are always small. ;)

Anyway, one more test for you. Right after you capture, play the captured video in Windows Media Player. Is it out of sync?

Then, do a short piece in Screenblast (hoping it gets out of sync for our purposes) and export it as an AVI. Look at that in Media Player. Is it out of sync? (This way we can see if it's actually out of sync or if the preview you're watching in Screenblast just seems to be out of sync.)

Meantime, a couple technical questions, just to cover all our bases:

What speed is your computer? At least 1 ghz? (Not always the issue, but just in case.)

Is the sound on your camcorder set up for 16 bit at 44,100 rate?

Meantime, run Screenblast's installer again (Don't delete the program first) and let it run its repair utility. Sometimes that fixes little problems.

Microhumor??? Actually, that's pretty funny. Not panicking yet.
I'm spending a lot of time these days keeping three different sytems bug-free, what an age we live in. Back to the problem:
Mediaviewer: I haven't reinstalled or been able to capture yet, but i hauled some of the "bad" files out of the trashcan and sure enough, they look and sound OK in Mediaviewer, and the whole shoot looks and sounds good on the camcorder screen.
System: i am running a Pentium 4, @ 2Ghz, 512 RAM, 80G hard drive, 70% free, defragged, debugged just before capture.
Camcorder is set at 16 bit, 2 channel. 48Khz. Not sure what you mean about 44,100 rate?
I will run the installer now, try the capture and get back to you. I sure appreciate the help, Grisetti

I'm way out of my league with this speculation, but here's a thread that discusses audio capture. It appears some people have had trouble when the camcorder is set to 48k while the capture setting was set to 44,100. Maybe causing a problem. Maybe not. You'll have to ask somebody smarter than I.

Meantime, I hope that by now you've run the fix utility and capture is working fine.

Okay, maybe you should disregard what I said in the last posting about DV audio. I clearly don't know what I'm talking about.

Can someone more tech-savvy help us out here?

I'm much better at things like making sure the computer is plugged into the wall, etc.

Seriously, I'll continue to work with you, Reg, if you're still having problems.

Grisetti:
Sorry, I have been out of touch, had to work!
Anyway, I am trying to find out how to run the fix utility, can you help me there, please! I had a look at the program folders, but can't immediately see what to do.

Just put the CD in your drive and, when the install screen automatically shows up, choose INSTALL. The program will see that you already have Screenblast installed and the autofix program will automatically start.

Good luck!

Grisetti:
I have the downloaded version ov SB 3.0a, build 100, so i only have the disk for v3.0
I did run the repair utility straight from the file folder and it didn't seem to do anything. Still had the no capture problem. Then I deleted the default.sfvidcap file and got my capture capability back!
By the way, my Video Capture software is version 3.0, build 90, would that make a difference??
NOW, I need to set the proper audio capture frequency, where do I do that?
It sure is great having a helping hand out there, as I am in Mexico and there's not much help down here!

My apologies, Reg. I was hoping by now someone more experienced with your particular problem would have jumped in and helped us out.

I'm just speculating, based on similar problems I've had or read about.

But try this: Select New Project under the File menu and check each screen. Make sure that it is setting up to output back to DV and that the default settings are set for the chosen settings.

Meantime, did you ever check to see whether the out of sync problem was happening during capture or at some other point during editing or output?

Grisetti:
Project settings were OK.
Problem definitely happened during capture, never did get to editing.
I followed your other instructions, (fix files utility) recaptured the whole mess, and it is fine on synch now! I am partway through editing this wedding video.
One observation I made before this problem emerged, and which I see again now, is that when I use auto scene detection, there is a very small difference between the video and the audio clip lengths, audio being slightly longer.
I think when I have a few days spare, I am going to reinstall the whole thing and uninstall VF 2.0
I really appreciate your help, I gues I'll be more careful capturing in future,
Many thanks again,
Reg

Grisetti:
The edited video is about 40 minutes, synch OK, EXCEPT, when I applied the cookie cutter videofx to the bride's farewell speech, it jerked that clip only out of audio synch, but other clips were ok. Of course I removed the fx on that clip and it is fine.
Many of the other clips have had other fx's applied without problem, usually the brightness/contrast fx. I haven't rendered yet.
Just another factoid for the trouble inventory.

Hi, Reg. Glad things are working for you.

Not to beat a dead horse here but, when you say the cookie cutter knocked things out of sync, do you mean that it looked out of sync when you played it in MS3 or that what you output (as either videotape or AVI on your disk) was out of sync on the clip?

The reason I ask is that, when you apply an effect to an event or clip, it often plays back slower or more jiggly than a non-effected clip. But note that this is only the "soft render" preview that you're seeing. Once you output your project to AVI (or tape), the effect is permanently rendered and runs perfectly clean.

As a test, you can drag over just the portion of the project that seems out of sync and outputting SELECTED PORTION ONLY as an AVI. If it looks clean in Windows Media Player after it's output, then you'll have no problem. In fact, if you'd like, you can even replace the effected clip with the output clip and you're all set!

Take car.

Grisetti:
Thanks for that, you are exactly right, looked bad in SB, but rendered it looked perfect in MediaViewer.
I learned at least 3 useful tricks this time, thanks to you, good luck on your own work.
This is a fantastic forum thanks to people like you. This issue is closed for me!
