[modsyn]

okay, i have attatched an error message i got from
virtualdubmod. it's probably the funniest error
message i've ever gotten. computers hate me, i swear.

may the float be with you.

If he doesn't know what floating point numbers are, that comment won't help him. If he did know what floating point numbers are, the error message wouldn't be so surprising.

modsyn:
The short answer: the frame-rates are inexact. The frame-rate to one of the segments may be 29.9700000001 and the frame-rate to the other may be 29.97000000002.

I recommend using AviSynth instead to join clips together.
seg1 = AVISource("foo.avi")
seg2 = AVISource("bar.avi").AssumeFPS(seg1)

seg1 ++ seg2

When the difference in framerates is that small it's better (no recompression) to set framerate with AVI [FR] changer (http://www.divx.howto.pl/modules.php?name=Forums&file=viewtopic&t=2578).

i've tried loading with avisynth, but i didn't know that
you could pass assumeFPS another clip as an argument.
if that works that would solve my problem.

and the error message was funny, not surprising. naturally, i
thought that if vdubmod could handle numbers that exact that
it would actually display them fully in the error message.
poo!

using AVIsynth should be avoided...

The framerate in AVI is calculated by deviding two integers (dwRate and dwScale), so more than often there a certain frame rate can be expressed in many different ways. (100/4 = 25/1). i think VirtualDub still thinks these are different frame rates though...

try to set the frame rate to 29.97 in the frame rate conversion menu and save with DSC for both files. then try to join the new files.

Well, the framerate is off by a miniscule amount that can be easily fixed by changing the file headers. Why would you reencode the video and thus lower the quality if it's not neccessary?

[stickboy]

Oh, right. I assumed modsyn would be doing some kind of processing on the video.
