Re: Import numbered image sequence, want to export same numbering

What has already been suggested sounds good.

Another option (if that doesn't work out) is to simply rename the files after rendering. This could be a bit of a pain if you need to keep revising the renders you are doing, but if you keep working until you are happy and then just need to deliver the final files, you COULD just rename them at the end. There are batch renaming techniques for both Mac and PC (on Mac, look into Automator, which is very useful for this).

But I agree it would be best to address it from within AE so you don't need to add the extra step and chase which files pertain to which sequence, and so on.
