I've done mine via FFMPEG and the command line. Because I'm hardcore like that. And obviously no processing that way. It outputs a nice H264 encoded video though. But not necessarily great if you want to edit after due to it already being compressed.
What sort of processing would you like? You could make the timelapse then edit the outputted video in whatever you like for videos. I've found proper editors and whatever the Adobe editor is to be quite complex. Is it encore or premiere? Or both. Not initially easy to do simple editing. Certainly is after you've read around, but then it's forgotten easily when you come to play again a few months down the line.
Keep meaning to do some more timelapse videos. Need to get off my arse and actually do them. It's not like they're difficult. Set camera up, wait for x minutes, move on.
