I'm not sure if there is a FAQ for this already (I could not find one) or if it even needs a FAQ.
I'm posting this here so I don't get in the middle of your discussion with Rick on the other forum.
I've had this problem a number of times now and I think I may have an idea of what is happening now.
Working with MPEG (groan) source files, when rendered to dv avi, flashing appears at some cuts where no flashing appears in edit. I think it has something to do with MPEG files refering to before and after frames.
In all cases, the symptoms are the same. The source files appear fine, the problem just shows up in the dv avi files made from the edited source files.
The first time it happened to me I was working on a "music video" but did not have very much source material to work with. I was using the very first frame of each new clip quite often. After I discovered the flashing problem, I looked closely at the dv avi file first and found the flashing was actually a one frame clip of a totally different scene sometimes semi transparent over the first frame I wanted, sometimes you could hardly see the frame I wanted anymore (The frames were actually the frame, just before the frame I was trying to get in my source files). When I looked at the MPEG project at the first frame, it was what I wanted with just a slight ghosting or blurring on it, but not enough to make out what it was. Unfortunately, you could clearly see what it was in the avi file. To correct the problem I just avoided using the first frame of a new clip if I could.
The second way I ran into the problem was importing a studio created DVD that I had made (also a "music video") using mencoder. The source material (DVD) was fine (even in a frame by frame check) but the ripped DVD had 3 cases of "flashing". To fix this one I just took out the incorrect frames (one was of a friend playing saxophone...the DVD was a horse video ) and replaced it with a frame grab of the next frame.
The third instance was not a cut, but it makes sense anyways. Again it was a "music video", this time of my daughter's grade 8 camping trip and some still photos. The last bit of video I had before some stills was of a friend with a camera taking a picture. When I rendered it to avi, I had a flash there! Actually, it looked quite good, like I had intended it to happen that way so I left it in. When I looked at the source MPEG file the last frame I used was fine but if you looked really close you could see just a slight bit of blurring. The frame that I had cut out had the flash. The funny thing was, I never noticed the flash in the orginal files but it is very noticable in the final project.
