I have four mp4 recordings of a video conference feed. After the conference ends, the files are multiplexed into a single video with each of the original files displayed in a quadrant of the output window. This works as expected if all four videos are of the same duration.
If the primary user starts recording at time T0 and the other 3 join at X seconds later, I need the individual videos in the muxed file to start at T0 + X. I also need the primary user's video to continue even after a subsequent user leaves the conference and their video ends early. My first thought is to lengthen the shorter videos by concatenating a black screen to the beginning and/or end to make the shorter video the same length as the primary one and to offset the short video to the correct point in the conference recording. Is this the best way to go, or is there a more straightforward approach? Thanks!
