Script observations:

Online video editing has to be done on the fly. Batch processing the frames and streaming the images for video clipping takes up a lot of disk/node space and easily presses the limits of the server.

We were fortunate in the demo to use underwater videos with no sound. To sync audio I would manually mark audio with periodic frame numbers and adjust if audio wasn't keeping pace. I've had some success with Perl and ImageMagick, but I think a customized server side C application is going to be more effective.


Please contact me if I can provide additional information.
