Choppy, slow (flickering) Crossfades
Hello,
I am using Sony Vegas 8 and I am having some problems with crossfades between video clips that are not smooth.
Please see the examples on this page–> http://www.mpn-ct.com/video
I have render 3 short clips, 2 of which do not have smooth transitions and one that does. All videos are from the same project, which makes it even more confusing as to why some transitions are smooth and others are not. I have tried rendering at both the highest quality and the lowest quality settings and get the same results.
I have use Sony’s Vegas Movie Studio Platinum in the past and have not experienced this. Since the version I was using was a bit out of date I thought I would upgrade to Vegas 8. And since I cannot import a Vegas 8 project into my old version I am kind of screwed. I have put together about 1 hour worth of footage with multiple transitions, fades and effects and I would really like this problem to be solved.
I am running an Intel Core2 Duo 2GHz processor with 3 gigs of ram.
Any ideas as to why this might be happening and any possible solutions would be appreciated. Thanks for your help!

I see this problem does not occur only when you play it in the preview monitor, but even after rendering. In that case, my tip probably won’t help, but it might:
pre-render.
Select one of the crossfades. Go “Tools” “Selectively Pre-render Video” “Render loop region only”. When finished, watch that section – is it smooth? Perhaps having done the pre-render, the render will work better. -
Michael, did you find the solution to your problem? I do encounter the same issue with Vegas 8c. I tried various projects settings and various type of transitions, each time the rendered file has these bad choppy transitions. On my side, all the sources are in 24p avi Cineform files(2 3 pulldown removal done with Cineform software). This could be the problem as when I try directly with the original 60i raw .m2t files from the camera and still output the final render at 24p, transitions are smooth as they should.
Thanks

I tried the pre-render method and the results were the same. I think it is probably my computer that is the weak link. When I was using Sony Vegas 6 Platinum to produce videos I was using a different computer that was a more powerful than the current one I am using. Unfortunately that old PC is not working. Maybe that is the problem, but I can’t 100% be sure of that.

Hi Michael, thanks for you answer.
concerning this issue, on my side it was related to using an old intermediate codec. Upgrading this codec fixed the problem. -
I think I have isolated the problem. The camera-unit that I used for filming was an all-in-one helmet camera that codes the video using XviD, for some reason that seems to cause the problem. I converted a clip, that was having problems, to an AVI and used that clip, and now the transition is smooth. I do not know enough about codec to explain why this is the case, all I know is that it worked.
