After fresh windows install, "blocky" capture

kk5551 wrote on 1/24/2006, 8:22 AM

I just took my pc into a local shop and had a fresh windows XP install as I was having some Window's issues. When I reinstalled Vegas and tried to capture approx 1 hr of DV footage it came back "blocky." About 5 across and 5 down blocks. Preview looked fine... I uninstalled and reinstalled but same problem..

Also, when I did a couple of quick test captures, 1or 2 minutes long, it captured just fine, but any long captures are blocky again.

I checked my settings and can't see anything... Any help?

Do you have DMA enabled for your drives? Are you sure the footage isn't blocky on the tape? Could you have had a dirty head spot that hit during the intial capture?

Also check to see if the add on cards have been replaced into different slots. I have a dual boot PC running Windows XP. Both boots were set up identically initially as ACPI Uniprocessor PC and yet internally the first time they ran they configured the hardware in radically different ways of distributing IRQs etc.

One boot handled complex audio far better so that boot became the DAW the other boot became the game and business machine.

But as Spot mentioned, the first culprit to look at is the DMA setting.

Yes DMA is enabled. Footage is fine and I captured using simply Microsoft Movie Maker and it captured just fine, crysal clear. I think it is strange that it will capture 1 or 2 minuted just fine, but when I try longer captures everything looks great on preview but when I stop capture it looks terrible and same when it is placed on timeline, like a checkerboard.

Been using Vegas for 3 years and never an issue w/ capture..

I had a similar problem once (maybe the same as yours, maybe not) - the capture program thought I was capturing PAL when it was actually NTSC. It only happened when I captured analog (VHS), and it was caused by a few frames of "snow" that confused the capture app. I started capturing a few seconds after the picture cleared itself up, and the problem went away.

If you're capturing from DV, then that's not the same issue, although maybe there's a setting for NTSC vs. PAL capture that's not set correctly?

After another install of Vegas I still have the same capture result. I searched other posts and it looks like I will give Scenalyzer a try. If there are any other suggestions please let me know..

I don't know if this will apply in your case, but it's solved some similar problems.

XP SP2 introduced a problem with some 1394 hardware. I'm assuming the\at the PC shop installed al the latest and greatest XP upgrades.

Do a search in Microsoft's knowledgebase. There is a hotfix and a registry hack that cures slow, nonresponsive or problematic 1394 devices. I don't know if this is affecting your capture problems, but it's worth a shot.
