Hi Lin & others... Just wanted to report back that I had at least some success with this. Thinking about the idea of a resource issue, it occurred to me that all my photos were 12 MP, and here I was trying to generate a 1920x1080 video. Since I had zoomed in 118% on most of my slides in order to fill a 16:9 frame, I batch resized my photos to be 2265x1504. Lo and behold -- the resulting 2-pass, max bitrate video worked! Clearly, there was no particular photo or audio file that was borking the video, but simply reducing the overall data size of the entire project did the trick. Interestingly, the max "24000" bitrate file was reported by my various players as peaking far higher than that, and I wish I knew what the setting really meant. Now, the other part of my goal was to be using the 7.0 beta to append a brief HD video clip to the end of my show. Unfortunately, while I can build an h264 video file of just that video file alone, when I append it to the show, then my resulting video again quits halfway or 2/3 of the way through. Once again, there appears to be a "resource issue" and/or the software simply isn't doing a good job of managing too much data, particularly since it seems to be able to handle one-pass, 10000 bitrate, but craps out on 2-pass, max bitrate. However, until I'm able replicate these issues on a different computer, I suppose I shouldn't point the finger... Brent
