Did you consider adding "-shortest" to your command line again?

Another cosmetic nitpick:
> [0:a]apad[padded];[padded]atempo=(24/(24000/1001))[outa]

If [padded] is never used elsewhere, and used exactly once as sole
input and once as sole output, I would write it as such:


Let us know how it works.
