comment FFMPEG: Why does the concat filter cause loss of a/v sync/lipsync?
Why use mp4box to split and concat? ffmpeg offers segment and concat options as well. Split using "-f segment -segment_time 10" and end with "360a-a%03d.mp4". Then create a text file with one entry on each line like "file '360a-a001.mp4", interleaving the entries in the correct order. Then join using -f concat -i text.txt and also with -flags +genpts -async 1

Can you post the commands you used? Both MP4Box and ffmpeg.

comment poor quality export of still images from premiere
Is the input source a set of PNGs? Any video footage involved? If not, try setting your sequence to 'Progressive'. As per the settings screencap, it's Upper field first right now.

comment Is it possible to encode video using the same codec and container but different parameters for different scenes?
Do you know of software that allows scene/regional parameters for MPEG-2 or AVC encoding? I have read that Hollywood DVDs are mastered by a 'compressionist' who uses tools which allow such fine-grained tweaking.

I haven't tested it. I just checked the syntax for glob @ jedit.org/users-guide/globs.html and it seems that %04d won't work. However, %?%?%?%?.png should work.

That would then select all the pngs present in the folder, besides 00xx.png, whereas the OP wants to queue only the %04d pngs without worrying about numbering continuity.

How about temporarily renaming them, making the AVI and then renaming them back to the (3x-2).png scheme? Bulk Rename Utility @ bulkrenameutility.co.uk/Main_Intro.php is a free, umm, bulk renamer.

Just check that your footage has been interpreted correctly in AE. Else a short snippet from before and after AE would be helpful.
