Recompression

[wannabepvr]

For those of you that recompress your video.

What do you use - and how do you find it?

And does it then play OK through GBPVR?

I used to be a TMPEGenc mpeg2 man but I am finding audio out of sync problems with high data rate digital broadcast.

virtualdub is an excellent free app for avi, if you're not married to mpeg

What sort of size (gig) per hour do find gives acceptable quality?

Not sure what you mean. If I want to keep shows (like stuff for my son), I do xvid, w/ a bitrate of 775

I've also had sync problems when compressing large files with TMPEGenc. I found a tutorial at videohelp.com that gets around the problem by using VirtualDub to extract the audio to a Wav file and then using that as your audio source in TMPEGenc.

Virtualdubmod is as fast as any, and allows for filtering and editing much easier than most.
The original virtualdub won't open mpg files, so make sure you download virtualdubmod, virtualdub-mpg, virtualdub-mp3, virtualdub-ac3.
Yes, there are at least 5 different virtualdubs.

Thanks Widman, I quickly tried this but didn't get a menu to separate the audio out. I'll keep trying.

Really I was hoping for a one step process. I look at how nicely DVDshrink transcodes and I would just love to apply this to broadcast Mpeg2. (As far as I see it DVD shring will only work on VOBs within a DVD structure?)

3.2Gb per hour is murder on HDD space!

Give it another shot and make sure you are using VirtualDub-MPEG2. Like reboot mentioned, the standard Vdub won't process an MPEG2 file.

I've heard good things about AutoGK...think that's free, too.

Virtual confusion! :eek: I will try again....
..... this looks more promising....at least I see an audio menu....yes can export a .wav file...but TMEPGenc can't read the source video.

hmmm....keep trying....
