Good tool to compress Mpeg-ps

[vmadahar]

I record my shows using the firewire off my cable box and it records using mpeg-ts format. I use HDTVtoMpeg2 software to turn the transport stream to program stream but the file size is huge is there a program out there (preferably free but any will do) that can compress mpeg-ps to something smaller but still be an mpeg so I can burn the files to DVD.

A good tool that you already have is SageTVTranscoder.exe (just ffmpeg with a different name). I use the following cmd to compress HDTV shows into DVD complient mpegs with their original AC3 sound...

"C:\Program Files\SageTV\SageTV\SageTVTranscoder.exe" -i "J:\Sage Recordings\INPUT_HDTV.mpg" -y -acodec copy -intra_matrix 08,08,09,11,13,13,14,17,08,08,11,12,13,14,17,18,09,11,13,13,14,17,17,19,11,11,13,13,14,17,18,20,11,13,13,14,16,17,20,24,13,13,14,16,17,20,24,29,13,13,14,17,19,23,28,34,13,14,17,19,23,28,34,41 -inter_matrix 08,08,08,09,09,09,09,10,08,08,09,09,09,09,10,10,08,09,09,09,09,10,10,10,09,09,09,09,10,10,10,10,09,09,09,10,10,10,10,11,09,09,10,10,10,10,11,11,09,10,10,10,10,11,11,11,10,10,10,10,11,11,11,11 -r 30000/1001 -bf 2 -mbd 2 -qmin 1 -mblmin 1 -lmin 1 -qsquish 1 -rc_init_cplx 500 -padtop 0 -padbottom 0 -async 50 -flags2 +sgop -deinterlace -b 7800 "J:\DVD\OUTPUT_HDTV.mpg"

This will convert 1.5 hours of HDTV into ~4.7 gig, but if that's too big you can play around with the bitrate parameter (-b 7800 -> -b 4800) to get the size down even more.

Hey evilpenguin thanks for the tip but I cant seem to play this output file under Sagetv or windows media player. I can play it fine using windows classic media player and mplayer for windows. And I wanted to know where did you figure out the matrices that you are using here and also all the options.
