Strobing Effect with GordianKnot

[happycase]

I'm sure there is an easy answer to this issue I'm having.

I'm new to GordianKnot, and am having trouble with turning VOBs into an AVI. With DGIndex, if the VOBs are 29.97 fps and 95% Film, I forcefilm it, demux audio, and save the file. I suspect my next issue is in Gordian Knot. I made an effort to create an avi according to the guides here, but must have failed somewhere. The resulting avi has strobing, and by that I mean there are grey frames inserted into the movie that have a strobing effect many times per second. I suspect that it's a fps issue that I'm not doing right somewhere. Mine is set at 23.976 fps, so perhaps change it? I would try changing it to 29.97 fps to see if that works, but the guide instructs me not to, so I assume it would not be worth my effort. BTW, I'm using the x264 codec, if that helps. Thanks in advance.

I'll get on that uploading, too.

Yes, that's the log.

I don't see anything terribly wrong: I see no functional errors, and nothing related to your particular problem.

I do see, however, that no compression test was run, your bits/pixels*frames value is relatively low, and you are incorrectly using the size of your .ac3 soundtrack for your initial bitrate calculation, rather than its estimated size when 128kbps mp3. This latter gets corrected for you, but if you ever pay attention to b/p*f values or do compression testing, you'll want to be sure to estimate soundtrack size correctly.

[happycase]

I just tried the encode again, except this time setting the bitrate higher and changing fps from 23 to 29.97 fps. Anyhow, the new file plays back perfectly. I guess it really (probably) was a fps issue. Thanks a lot for the feedback, jggimi.
