Fade weirdness
Occasionally I’ll get just a freakout flickering effect (a still grab is the image below) when I do a simple fade from one video clip to another. It renders that way, too, so I don’t know what’s causing it or how to avoid it.
Any ideas?

Which version of Vegas are you using, and what format is the clip? Is this in the render or preview? I don’t have an answer, though this might help someone else answer you. The only problems I’ve had with fades are when Vegas 9 would take a frame from a clip immediately before a fade in, so I had to move it further down the timeline.

I’m on Vegas Pro 10e, format is AVI captured from DVCAM tape, and the glitch happens both on preview and render.

Only in fades? Does the footage play normally in the same spot without a fade?
I’ve had lots of problems with avi on Vegas (currently I still use Vegas 10e after Vegas 11 was horribly buggy), though it was Cineform avi, so I don’t know if that makes a difference. Vegas would crash and lock up constantly.

Yep, only in fades. Looks fine, otherwise.
And, I thought AVI was the “favored” filetype of Windows/Vegas, no?

The problem of transitions and fades being intermittently wrong still exists in Vegas 11 (build 511) as well. My problems have almost always occurred if the clip is stretched and then put in a transition or has a fade. The horrible thing about this problem is that it is not consistent. It will render as a problem if the preview shows it (most times the clip will just change to one color channel and not break up as you have shown) but reopening the project or even just playing the preview again later on it will be clean. This makes it impossible to know when and where these transition anomalies will show up unless you preview the entire project before rendering.
What I have found trying to fix these problems is this. It happens almost exclusively in 32 bit color format. Unfortunately switching to 8 bit color mid project is an impossibility. Are you working in 32 bit color? By deleting a frame here and there or just changing the transition cross points the anomaly will go away. I have yet to find a reason for the anomaly in the first place as most of the time the transitions are put on the same video clip (so codec issues are not the problem.)

Kelly, the only times this has happened to me (and it makes no sense whatsoever) is when I’m using footage that was shot on a brand of tape that I don’t regularly use (i.e. client supplied).
The capture appears to be normal and the footage plays fine in the timeline UNTIL I apply any FX to the footage.
Most of the time, a re-capture solves my problems. -
Don’t ask me, because I can never seem to get a straight answer from Sony about what my problem with avi footage is. I don’t know if it’s all avi or just Cineform avi.
