Web Videos via Watch Folders Transcode What I am looking to do is fairly simple, however seems complicated in theory.

What I need to do is be able to have a folder where all video files placed in the folder, are transcoded to all applicable web video formats (H264, OGG, WEBM, FLV) Then placed into another folder...

I can set this up to a certain extent using Adobe Media Encoder however I need to use source Frame Rate, and Frame Size, as these clips will vary in range from PAL to NTSC to HD...

I am open to using FFmpeg but cant seem to get it work in the Mac Environment correctly doing what I want.  Any software as long as it is mac based would work, but must be able to create all 4 of the above mentioned formats.
...FFMPEG worked, it was a steep learning curve in terms of getting it to work in my environment and, took me a few days to learn how to code in Bash Scripts Shell based, but in the end very happy with the results and it's integration with both Macs and my Unix server.
