sticky fades

Even though this kinda relates to all editing software, I use premiere so I thought this might be a good place for it.

Have you ever noticed that on a cross fade near the end of the fade there's often a frame or two that's outline kinda hangs on the new scene instead of dying quietly like it should?
This used to happen a lot to me when I had some orphan frames (or frames from and adjoining scene) on the tail end of the cross disolve. That's easy to fix as it's just sloppy editing on my part. But I've noticed (mostly with PAL sources converted to NTSC if that makes any difference) that the partial scene outline hangs there a bit on cross fades, about 80% of the time swapping to key framing the opacity manually (instead of being lazy) fixes it.
But on my most recent video the little buggers are like termites although I'm over fixing it after 20+ hours of stuffing about. I thought it would be interesting to find out what's causing it for future vids. Unfortunately there's no screen cap to help illustrate my point.
Is it an uneven/error during the render of the transition or keyframes? or something or my DLP(DPL whichever order it goes in) playing up? as I can often see the colours that make up an image/text as my eyes/brain works faster then the refresh rate of monitors (projectors are so slow I end up with headaches, yay for being in that 5% of the population :\ ) i.e just my quirky genes? or do others have this problem too?

I know what you are talking about, no clue how to fix it, but you can only see it on playback for some reason so there is no way to effectively "screencap" it cause going through it frame by frame, theres no way to see it...

This has cost me many hours from having to go back, fix and then rerender everything. I've taken to prerendering all my fade spots beforehand.

I tend to get them in both play back and on exported files... I also rarely pre render the timeline (since I edit with losses and get almost no lag on playback I usually dont bother) eh maybe I'll try doing it a bit more and see if it helps deal with the sticky fades.

Yes, I've dealt with the problem immensely!!

Here's how to fix crossfades without getting the little frames at the beginning or end.

Instead of using the crossfade transition, just clip the pieces that you want and layer them at the ends in an upper or lower timeline. So clip A will go in timeline 1 and clip B will go in timeline 2 (above it). Clip A will slightly extend into B, so just use the fade out on the tail end of A. You will never get bits of frames you want.

Unfortunately there isn't a way I know of to fix the cross fade. Hope that made sense and hope it fixes the problem : )
