I'm sorry if my post wasn't clear enough - the audio was fine. Some of the video tracks were missing. We had one audio track and a number of video tracks for each of the stills so that we could manipulate them individually. When we rendered the sequence to an MP4 the audio track was present but most of the video tracks were missing. We are using 8.82 (licensed version). The version that you linked to is 8.45. When I tried 8.45 on a different machine (unlicensed) it still wasn't perfect (some issues with aspect ratio/scaling) but it worked a lot better. But then I ran out of free exports... I upgraded the original (licensed) machine to the latest Windows version (8.91), and it seemed to fix all of these problems - I now have successfully exported an MP4 of our sequence that aligns with what I see in preview. Thanks for your help, @borate!

We are having similar issues to those described in this thread. We made a short 35s video out of a dozen stills. There are around 12 video tracks (corresponding to the stills) with some simple animations/transformations, and an audio track. When we preview, it plays how we want it to play. However, when we export to MP4 most of the video tracks are missing (the sound seems to be ok). Any insights would be appreciated.
