in the past on my G4dual I had an alchemyDVR card and recorded analog TV with sorensen3 to 320x240 files.
I edited them and then saved them as 3ivx files that ended up about 150MB for 20 minutes of TV
this worked for me as I used QTPro to get rid of what I didn't want and then Batch Export Utility to do the final 3ivx conversion in a batch, unassited.

now with my MiniHD I get initial file sizes of about 900mb for 680 TV and 3gb for 1080 HDTV for 28 min.

using SClip I can batch a lot of them over night but need help in selecting the initial codec of choice for a final 150mb 329 x 240 file size.

I can edit with QTPro after the streamclip to QT, then use BEU to go to the 3ivx.

im just unfamiliar with all the Streamclip to QT codec choices

thanks
