On my 5D, I could start a batch using MPEG Streamclip or Compressor, and churn out proxies for a producer very quickly. With the FS100, I have not discovered a quick and easy way to do this yet. A one-step process is really what I'm seeking here - something that I can set to transcode files to something like 480x270 1500kbps h.264, and put it in a dropbox folder I can tell the producer to start watching as they populate.

Any suggestions?

ClipWrap will do what you want.

Sorta. I'm using ClipWrap to make them full-rez h264 movies, then streamclip to compress them to tiny h264 movies. It's a two-step process. I'm halfway there. :-)

I'm pretty sure you could use ffmpeg command line to do it all in one step, and you could also batch them.

ClipWrap will not automatically join long files - you have to do it manually. FYI, for those reading this in the archives someday.
