View Full Version : Encoding MPEGs?

I have some movies in MPEG format that I would like to shrink down by re-encoding them.

The encoder I've used for all of my DVD movies is HC Enc with DVD-RB, in order to compress them down to fit onto a single DVD-R. But I don't plan on putting these MPEG movies on a DVD-R, I merely want to store them on my harddrive and playback on the computer alone. I'd like to shrink them down as much as I possibly can while preserving quality in order to save the harddrive space.

How could I setup HC Encoder to 'compress' it a custom %? Normally DVD-RB handles that for me by calculating how much is necessary to fit on a DVD-R, but seeing as how the files are only around 300mb, I think I need to do it manually to make this work.

ps: Since I don't intend on playing this on a TV, would reducing the frames per second from the usual 29~ or so a TV uses to a modest 25~ also cause the movie's size to be reduced? Is it even possible to do that?

Thanks.

old bitrate * percent/100 = new bitrate :)

to find the old bitrate you can use bitrateview or something similar (though bitrateview free edition gives wrong numbers, so you have to multiply by 1.024 to get the real rate).

Have you considered DIVX or XVID for low bitrate movies?

For storing to and playing back from your HD, using only your computer to view, I agree Xvid would be the way to go.

Check out the Xvid forum here at doom9.
