vegas and avi video

[jsgogeta]

I was wondering what filter is better to recompress a avi video output because I am trying to render one of my videos and I lose quality and also the audio goes 2 to 6 seconds offset and I want to know what am I doing wrong.

Thanks in advantage!!!!!!!!!!!

Audio: 124 kBit/s, 48,000 Hz, Stereo, 01:09:16;26' MPEG Layer -3

Hope this helps!!!!!!!!!!

I don't think your probelm involves your coice of DirectShow video filter. I've downloaded the occaional divx avi from the net, and the way I've always found of avoiding audio sync problems is to first run VirtualDub or Soun Forge or Cool Edit Pro and extract the audio track to a straight 48 khz WAV file. Then I fire up VDub and use the avi divx elementary video stream as the video source and output to a type 2 DV avi, either using the Microsoft DV codec in Adobe Premiere, or using the MainConcept DV codec via VirtualDub.
Then once the elementary video stream has been converted to Type 2 DV avi and the elementary audio stream has been saved as a 48 khz linear PCM wav file, piont a good mpeg-2 encoder like Mainconcept or TMPGenc or Procoder or CCE at the video + audio streams and generate an mpeg-2 file from it.
In my experience this eliminates all audio sync issues.

As for poor video quality, I'm afraid that's the nature of the divx beast. Downloaded avis look like crap, because they're always encoded at an inadequate bitrate. THe only workaround invovles using a lot of vdub filters, which can chew up to 11 hours of 2.4 Ghz P4 CPU time per 45 minutes of divx file. The results look okay, but not fabulous. Downloaded video just looksmediocre on anything other than a computer monitor. It looks semi-OK on a computer monitor, but it's never going to look very good no matter what you do. The bitrate just wasn't there in encoding.

Vegas hates VBR MP3 audio, so follow SpectroElectro's advice re: stripping off the audio as uncompressed wav. I wouldn't convert the video, though as Vegas should be able to load it. Certainly, converting to DV will reduce quality because you are pushing through yet another conversion. If you must use Vegas, output directly to mpeg-2 using the built-in Mainconcept encoder.

Personally, I wouldn't bother trying to join them. There is nothing to be gained, and just audio problems to be had from this. Encode each as a seperate episode, then author then correctly to do what you want. If you have a standalone mpeg-2 encoder, I woulf use VDub to do the resizing, then frameserve to the encoder.

Can I suggest you do something? Download and install a codec named Huffyuv (go to TOOLS and search for it). It's terrific. No loss of quality at all ( at least that your eyes can see).
