Alright, I know that this is the new the whole transcoding thing, and I personally have not put a whole lot of time into it but I was curious, if I could choose to have one of these programs transcode all my extras down to basically nothing and leave teh main movie alone, then I would theortically have all the extra's reduced to basically nothing, and then I could rip apart the main movie and work with that in CCE and DIF4U?? Kind of curious if anyone else has touched on this type of integration...b/c personally I'm not a quality perfectionist with extras as Iam with the main movie.

I do a mix on the 'challenging' titles that have lots of extras. I like InstantCopy because it also crunches down the 0*_0.VOB files (typically menus) easily- one of the only programs that I am aware of that does this.

I basically setup InstantCopy to crunch the menus down to 40%, the extras that I want InstantCopy to crunch, and whatever is left for the movie- don't care on that.

Then, I will often redo several of the VTS's with CCE- IC's (and DVD2ONE's) big downfall is it has no way to InverseTelecide any material that clearly is a candidate for this process. I find MANY extras that can be safely IVTC'd, and this REALLY saves some space. CCE at Quantization Factor of 80-90 will often beat the pants off IC at 40%, and often with smaller files yet because of the IVTC. These redone extras I author one at a time with Scenarist, and IFOUpdate them back in using the InstantCopy IFO's as the 'original'.

Then, of course I go to work on the main feature, and use CCE.

Yes, this process is time consuming, but absolutely necessary for some films if you want to keep extras and have good quality. I tried to do 'The Patriot' with InstantCopy- YUCKKK. My final result is far better. Most of the time, my computer is doing all the work, while I am off watching other movies.

Is there anyway of just using it to reduce the menus? i'm tired of sacrificing bitrate for the movie and extras to have 1GB wasted on menus.

If IC can work on the menus and not try to recompress the movie and extras itself it would sound very nice,that way i could do the rest of the work on CCE and some authoring program.

@Calypso,

Are you sure there is a need for inverse telecining in IC or DVD2one in most cases? In transcoding the two MPEG-2 streams should be identical (except for compression size) before and after. That means a progressive stream should remain progressive after transcoding. The telecining normally takes place at playback -- although I suppose there may be instances where material was actually recorded after telecining.
