Sony Vegas 6.0d - Playback is Slow and Glitchy

Postby RIPmyprsoul » Sun Feb 04, 2007 12:36 pm

I's so annoying, any format of clip I put in the video track it has gaps in playback. Especially when I add in effects, transitions, and etc. Is there anyway to fix this?

Are you trying to put in clips that are encoded with DivX or XviD on your timeline?

No I'm putting in clips with AVI format and MPG Format (Because I have the MPEG 1/2 MainConcept Codec)

Are you sure it's not just preview lag? This happens with every video editor; are you just letting the video play or are you building a dynamic RAM preview first?

Drag a loop around the portion of the video you want to preview and press Shift-B. If you want to be able to preview more of your video, go to Options>Preferences>Video and make the Dynamic RAM Preview max (MB) number higher.

Use VirtualDubMod to convert the clips to a lossless codec, like HuffYUV or Lagarith. Read this to learn how.

Thanks im tryin that but when i open video file in virtualdubmod it says. Virtualdub has detected an improper VBR audio encoding in the source avi file audio stream 1) The current prefrence is to rewwrite the audio header with standard CBR values during processing for better compatibility. This may introduce up to 15819ms of skew from the video stream. if this is unacceptable, decompress the entire stream to an uncompressed wav file and recompree with a constant bitrate encoder. bitrate: 135.9 +19.6kbps. Ok when i try to process says the file output for the video in virtualdubmod is like 20 something gigs. I already encoded this file using other program Nero Vision and it works but the mouths of the people in the show are fast and audio plays very odd thru the tv speakers for playback. maybe ill try the bitrate encoder for the audio. please if someone has more advice please help thanks. appreciate it alot.

Are you using the audio from the file? if not it doesn't matter. If so, do what it tells you to do.

If you're transcoding an entire episode of something and the setting is uncompressed, this will be perfectly natural. Even when encoded losslessly, you're files will be several GB each. That's why you make clips and only save those.

This last bit here suggests that you're doing something other than creating an AMV... especially if you're using the audio from the series for something... clarification is in order - are you making a video that needs sound clips in sections? Or are you not making an AMV at all and simply trying to burn fansubs to DVD?
