all I want to do is encode an avi file

[moopsimoo]

ok here is my small yet hair raising issue. I am trying to rip some dvds that I have to encode at various bitrates. I used dvd decrypter and them vobtompg to make the avi file and that seems to be working fine. But the size of the file is huge(5gb) and I am trying to compress them for websize. The whole file plays well in all media players but when I try to encode it into a different bitrate via TMPGNC the audio dissappears. All i want to do is be able to have the whole movie output so that I can edit it with vegas..any queestions on my audio issue?

what you did was to take the vobs and convert them to mpg. not avi. all you need to do is to import the mpg into vegas to work with it and then you can encode to whatever it is you want. it may take a while for vegas to demux the mpg, so be patient.

aah i see..i will give it a whirl now. Would the audio disappear if the file was going from a mpeg2 stream into a mpeg1?

[aedipuss]

mpeg-1 and mpeg-2 are different standards and need different resolutions and different audio. you would need to re-encode both the video and audio to those standards to get it to work.

moopsimoo, how small do you want the file to be and in what format?

If you need, for example, a 700MB size, then a AVI type format like Xvid or Divx may be more suited. Those size files are common on the web, at least with P2P. Better quality is achieved at 1GB in those formats.

DVD or VCD formats may end up being at a much lesser quality at those sizes. For most full length videos, 2 or more VCDs may be required. A file that fits on a single DVD-5 can be up to 4.37GB with good quality, but that would be overly large for 'websize'.

If you want to try Xvid/Divx, AutoGK would be one program to look into. It can convert a ripped DVD directly to Xvid/Divx formats and you can adjust the desired filesize. Or for higher compression/smaller size, H264 is one option. But playback is more limited to just computers. Even WMV is one choice for high compression.

And welcome to our forums.

I would prefer the files be anywhere from 300 to 500 mb for 15 minute scenes. I just want a nice clean solution for these video files. Thank you all for the help so far. I think im getting closer with every post i read

the audio is still missing from the files in the video ts the audio file log is as such: 0x80 - Audio - AC3 / 2ch / 48kHz / DRC / English / LBA: 8 / PTS: 00:00:00.233 / Delay: 0ms

Do you have a AC3 decoder like AC3 Filter installed? If not, then they wouldn't play back. Check them with Gspot 2.70 to see if the file is missing. VLC can also play AC3 files.

Or you can decode the AC3 to MP3 or WAV, depending on what you want to do with it with AC3 ACM Decompressor and VirtualDub or TMPGEnc encoder can work with it.

A 15 minute video at 400MB would come out to about 3100Kbps bitrate. A little on the low side for MPEG-2 full D1 encoding, but OK. Or you could use 1/2 D1 and it might look better. It's too high for VCD format. You could probably cut that down to 200MB or a little less with Xvid/Divx. This is from the VideoHelp Bitrate calculator

WELL hot damn! downloading the AC3 filter is exactly what I needed to do.Now the audio plays just fine
