virtualdub full processing mode cause lag voice and video

[ww_to_2003]

When I use full processing mode to convert the AVI (DV format) to AVI (DV format) with smooth deinterlace filter and avisynth, I get a lag video and audio. When use direct scream copy, there is no lag. I have try to different PC and get the same result.

Help Please.

If you are talking about previewing with the Output Playback button or via File - Preview Filtered -- VirtualDub is not designed as a media player. It certainly won't play smoothly with a bunch of filter applied.

If you are talking about playing the resulting AVI file -- what video and audio codecs did you use? If you saved as uncompressed RGB the file is probably just too big to play smoothly.

Why are you deinterlacing? Are you converting to Xvid or similar? If your final destination is MPEG, you don't generally want to deinterlace. Is the video shorter when deinterlaced?

And welcome to our forums.

Thanks guys,

It is the file size that causes the problem. After I convert to H264 AVI, the lag was gone. Thanks again.

The video codec is the panasonic one. I don't know what is the audio codec. I just use direct stream copy in virtualdub.

The purpose for deinterlacing is to convert the DV file to H264 for backup. I will keep two sets of copies, one will be interlaced DVD format, the other will be deinterlaced H264 AVI so I can play the movies on the computer screen.
