Vegas 10c has artifacts in transitions
Hey guys, thanks in advance for any help. So here’s my issue, every once in a while (it’s not consistent) when I overlap two clips (of the same resolution and bit rate) the dissolve between is completely messed up. It looks like artifacts, but more so it looks like that instead of fading, its flashing between the frames of the two clips and it’s very unsightly. This is a new problem I’m having, too. I’ve been rendering and editing with these settings for a few months now and this problem only cropped up last week when I started editing in 720p with videos from my DSLR (Pentax K-r, if you needed to know). It happens in vegas and in the rendered video. As a background, I’m not new to video editing and have been using vegas for about a year, so I’m pretty familiar with it, but this has got me stumped. Any help would be greatly appreciated!
Below is a link to an unlisted youtube video where you can see the problem in action (it’s at about 1:30 in the video, I didn’t feel like editing down the whole thing). You’ll notice, if you watch more, that the rest of the transitions are fine, even at different play speeds (I record at 1/2 speed to emulate 60fps, so slowed down clips are actually at 1x and normal speed is actually at 2x). As an aside, I’m rendering WMV at 720x480p at 30fps, 4MB/s.

Set dynamic ram to 0.
Prerender that section.
It’ll probably go away. This appears to be a codec issue.FWIW, I watched this thinking you’d shot it with HDSLR. Might be a good idea to render out problem areas vs the longer view of a videogame (which suggests you used Camtasia or similar, so it’s already a challenged codec, thus suggesting a buffer problem).

Setting DRAM to 0 did the trick! And I record with a dazzle through pinnacle studio, and it outputs uncompressed AVI files (35MB/s). It was the same with the DSLR that saves uncompressed AVIs (26MB/s), so I don’t think it was the codec. Do have an idea why this would just start out of no where?
Thanks again!!

I’m still having this issue, even with DRAM set to 0. This time with footage from my DSLR. The source file is uncompressed AVI at 26MB/s bit rate. i linked an unlisted video with the transition in question. Any help would be awesome!

Hi! Did you ever find out what caused this? I’m having the identical problem when overlapping footage recorded on a Sony MRU and other footage… footage looks fine when not overlapping, but when it overlaps for standard crossfade it shows artifacts with frames jumping between the two clips.
This happens in the preview.
It also happens rendering out to MPEG2, or DV AVI.Changing Dynamic RAM setting did nothing but slow things down…
HELP!

I have not. But, I upgraded to Vegas 11 and fresh installed the problem seems to have fixed itself. I’m sorry I don’t have a solution :/. Try a fresh install with no plugins.
