I'm trying to figure out how to recode High Def (non-encrypted) transport streams to H264 using ffmpegX. I'm hoping H264's efficiency will let me squeeze more episodes onto my drive than just keeping the raw HD TS.

I can use MPEG StreamClip to trim out the adverts and end up with an advert-free show.

But what I can't figure out is how to transcode/convert the resulting TS file to H264 at 1080i

Using 10.4.7 and DP G5 2.5.

Suggestions as to how to proceed would be greatly appreciated

thx
