Hi,I have this problem sometimes and I don't know why.I record some programs from TV and in these clips I make cuts to erase the parts that I don't need to final video.I cut then I put the parts next to each others.In the timeline all seems good,one clip ends and starts other without problems.When I export timeline sometimes between clips i see a black screen,I hear the sound but when the image comes back i don't see the start of the clip because instead of seeing the start of clip I see the black Screen.I use 2 video tracks,one with the title and another with the video.The track that have the title in transparency is set to Multiply,so I can see the title and video.I use also the Divx 6 codec.What could be the problem?
