I'm not sure of what I'll rewrite the script in. I know a lot more about transcode now then when I threw together this one. I pretty much wrote it as a proof of concept. Like most hacks it became to useful and it did the job well enough for me to be happy with. I've though about redoing it in perl or C but bash seems to work just as well and most people can understand it to hack the script when they need to.
I don't remember why I disabled the frame rate stuff. I do know that I was confused be cause of the output differences that tcscan and tcprobe would give me. Tcprobe would give me a frame rate of 23 and tcscan would give a frame rate 29. I never was sure which one to use so I just figured I would let transcode figure it out. Awk was a hack. It was the first thing I though of when I realized that I couldn't get bash to the required math right. I hacked together this script at about 1 am and was probably flying on one wing and a few cups of coffee. Anyway, I figure out how to do what I need to do with bc but the awk code works well and I'm to lazy to replace it. I need to tighten up the size part of the code anyway. AutoGK on windows will nail the proper size with in a few meg. Mine gets close, as in tactical nuclear weapon close. I just looked through last nights work and I had set the -s to 650 MB. Most of the files are 649mb to 651mb but a few where 550mb and 620mb. Funny thing is they look perfect despite the size differences. I'm just chalking it up that transcode knows more about what is doing than I do. One of the things about using the batch queue is it will also mail you a copy of the stdout and stderr when each file is done. That way you can dig through them and look for errors.

Thanks for this contribute, I'll upload to wiki ASAP unless of course take care more quickly.

(I'm an awk enthusiast even if not so expert ;) ) Maybe bc can be useful here?
