I've been moving TV shows from my TiVo to my computer for a few months. 1hr of HD is about 3.3gb and I'm trying to get that cut in half. Just so you guys know the workflow so you can properly help me let me layout the path. TiVo -> iTivo (takes the .tivo package off and puts it in mp4) -> MPEG StreamClip (remove commercials) this program doesn't touch the file format at all that I can tell because it's really fast at re-saving my file as an mp4. After that I have a perfect TV show with NO issues. It's just a big file. Now I'm sticking it in HandBrake to "shrink" it. After it comes out of HB the audio is fine for a little while and then it's off by 1 sec then it's back in sync, then it may go out again by 3 sec all in the same video. My HB settings are Format: MP4 Video Codec: H.264 (x264) FPS: Same as Source Quality: I just chose Average bitrate set at 4000 Picture Size is kept same as source. Some are 720p some 1080p No picture cropping Audio: Unknown (AAC) | Stereo Mix | Auto Samplerate | Bitrate 128kbps So am I correct in assuming that HB (my incorrect settings) are causing my problem? I stole a few settings off the HB forum but they all are discussing DVD rips. I didn't see a thread discussing how to shrink an existing mp4 file. I have found another program called QT Sync that can fix my screwed up HB file. But I'd rather have you guys tell me I'm setting something up wrong so I can just Queue up some vids and let it run. Thank you very much for your help.
