A few Devede questions

[eboven]

So I recently installed ubuntu Hardy on my older computer and I love everything about it except burning DVD's. I have been using Devede to convert avi files that I have on my hard drive to a disk image and then I use Brasero to burn the image to a DVD disk. The problem I'm having is that the result is of terrible quality. The original avi files are about 700-800 MB and I use a video rate of about 5000 Kbits/sec and an audio rate of 224 kbits/sec and I format it as NTSC. I burn these images, (which rarely exceed 3 GB, even though I specified to Devede that my disk is a 4.7GB DVD) to a DVD disk and put them in my upconvert DVD player. The quality is that of analog television, black gets are very blotchy; it doesn't even look as good as a normal DVD without the upconvert. Anyone have any ideas about what I'm doing wrong here, or have suggestions for a different method for burning avi files to DVD format?

Also, I noticed that on most of the DVD's I burn, the sound is spot on in the beginning, but as the movie continues, it gets progressively more and more out of sync; so bad that it's often times unwatchable. Any ideas here?

I can't help with the sound problem but for DVD's you can go up to about 9000 Kbits/sec. Try a higher bit rate. It will go nearer to the full DVD and will improve quality.

There are bit rate calculators on the web that allow you to put in the disc size, length of video etc and they give the best bit rate for the job. try a Google search on bit rate calculator. However I've been told not to go over about 4.4Gb on a DVD as there are other overheads that limit you to this as the approx max available.

Thanks for the reply, I will try a bitrate calculator out. Anyone else have any input on the sound issue?

I had the same sound issue. I got it solved but I am not sure anymore how. Either changing the frequecy (48000 to 44100 or dvd to audioCD format or vv) or I forgot to select PAL so the encoder encoded wrongly from PAL 25 fps footage to NTCS 30 fps footage). I think it was the last.
