Bitrate End result

[hhache]

I have some medium quality Avi files I want to put on SVCD. The AVI is exactly 700MB and fits as data, but obviously can't play on DVD player. Need to convert to mpg..ok, no prob, but always get a 1.5+gig file...Two questions:

1. Any way to convert the AVI 2 MPG and keep same size? Will quality be affected?

2. The AVI bitrates are video is 900 KBs + audio 192 KBs. In converting to a SVCD (or DVD), will quality improve if I reencode to MPG at, say, 2200KBs or higher? Or would I get same quality as AVI at say 1200 KBs?

Thank you for reading and your help!

how long is the video

[hhache]

Timewise itis about 1 hour :40 min...

no quality improvement converting- the opposite if anything. If your material is 100min long you're going to need at least 2 cd's.

By my calculations you'd need to re-encode the video at 888kbps which would be really stretching it quality-wise IMO. If you wanted to give it a go anyway, you could try this guide.

Quality doesn't/can't improve ... significantly, that is ... with the exception on occasion of filters, which may appear to improve the appearance to the eye slightly. Garbage in = garbage out.

You're AVI is probably Divx or Xvid (MPEG 4) video. They are 2 to 3 times more efficient than MPEG 2. So you'll need 2 to 3 times more bitrate if you convert them MPEG 2 (at the same frame size).

use a dvd mate, MUCH more space and can use a lot higher bitrate
