Entree Rep: 0 Joined: 07 Feb 2005 Posts: 2 OFFLINE | OK someone please tell me why this won’t work. In VirtualDub, I call up my .avi file (video codec Xvid, audio is MP3) and I get this message:
VirtualDub has detected an improper VBR audio encoding in the source AVI file (audio stream 1). The current preference is to rewrite the audio header with standard CBR values during processing for better compatibility. This may introduce up to 7165 ms of skew from the video stream. If this is unacceptable, decrompress the *entire* audio stream to an uncompressed WAV file and recompress with a constant bitrate encoder. (bitrate: 127.9 +- 11.3kbps) Do you still want to rewrite the header?
Now the problem is, when I use RealPlayer to playback the .avi, the audio is ahead of the video but it gradually works itself behind the video over time. Even weirder is, within VirtualDub, the MP3 decoder that works fine in RealPlayer gives me no sound in VirtualDub, and I’m trying to preview the input playback to get an idea of the a/v offset. But the video behaves much differently in VirtualDub and by the end of it the sync is off by at least 10 seconds. In RealPlayer, it’s not that bad.
So it’s not apples and apples; therefore I have no idea how much I need to time-warp the audio stream in Goldwave. Do I just want to save the audio out of VD as a .wav and then re-encode as MP3? I assume Goldwave can do this re-compression since I have the option to save my WAV as a MP3 with a 128kBit/s rate.
Or maybe I’m just way off in this whole thing, since I’m completely new to this scene. I’d appreciate any comments that can help me get through this.
