I'm stumped and I hope you can help; my client needs a looping video for display on a kiosk at a franchise meeting. The file format I've decided on will be a 1280x720 .mp4 video that will loop in Quicktime on a PC connected to the 50" LCD display. Here's the problem I'm running into; the assets were given to me as .m4v files that were ripped from some DVDs using Handbrake. (Note: the source files were created internally by employees using a variety of video cameras and smart phones). The file size is actually less than SD (652x376) so I cannot size them up to 1280x720 without it looking like total crap. Since there is an "art" theme for the event, I came up with a simple solution; I found a stock image of a painter's canvas for the background, and a gilded picture frame that creates a smaller "window" for display of the video. I dropped the .m4v files into the timeline, used Pan/Crop to size them to the window, and I thought I was done. WRONG ...
There are some sync or display issues with these files that show up in the preview window and also in the final render. First, if I shrink the size of my preview window, the image disappears. This is annoying because I have 4-5 different video and audio tracks in the timeline, and I can't view them all and the preview at the same time. Second, when I render the file I get intermittent "flash frames" of diagonal lines of static garbage in a rainbow of colors. It happens usually near transitions in the video clips with sharp contrast, like a fade to black or up from black. One section that is supposed to be in black and white gets completely scrambled.
Could anyone shed some light on what's happening here?
