occasional (really) bad quality video encoding

[perthmetro]

I'm using autogk to mass convert all my home digital camera mjpeg(.avi) movies to xvid. I occasionally get a real shocker as far as the video quality goes, whilst most are fine.... any ideas why?

Hi,

1 or 2 pass?
Contains lots of dark scenes or fast movements?
Average bitrate?
Eventually post the logfile of one of the problematic encodes...

the standard autogk encoding for xvid on 80% quality ... so no idea passes, and bit rate... it encodes fine if i do it manually with VD

When you do it manually with VirtuaDubMod, do you encode with multi-pass? AutoGK percentage quality is single-pass, which will create artifacts in higher-motion scenes.

single with VD... I just use the normal encoding with autogk, so whatever they are i dont know... there appears to be no common theme to the ones that encode badly... are you aure autogk is only single pass?

[manono]

The Target Quality (Percentage) is 1-pass. The default where you choose the final size (700 MB, 1/4 DVDR, etc.) is 2-pass.

any other suggestions as to why it is going wrong?

whats a log file and where is it?

A log file is a recording of what AGK finds, figures out, anticipates, and does. You can find it in the working directory, look for a file named <Movie Name>_agk.log
