What's wrong with WMV-files?!

[FallenAngelII]

Depending on which media player I use, the length of the WMV-file will vary!

The same video file played in different players:
Zoom Player - 03:09
Media Player Classic - 03:09
Winamp - 03:09
Imported into Virtualdub via .avs: 03:09
Windows Media Player - 03:10
Imported into Adobe Premiere Pro: 03:11
VLC Player: 03:14

OK, what gives?!

I also imported a WMV into Virtualdub by way of fake .avs (an .avs specifying the WMV-file) and re-encoded it into DivX-AVI.

I then imported the original WMV and the new DivX-Avi into Adobe Premiere Pro. The new DivX-Avi was 13 frames longer than the original, but it turns out this is the length is should be as this particular WMV shows up as 02:59 on all players (besides the ones showing it longer) but in Adobe Premiere Pro, the original WMV was only 02:58 (and 16 frames).

When I read this post I thought "variable framerate" maybe? If I'm not mistaken WMV can support this which is a pain in the a**. Maybe different apps read VFR with a slight difference. I'm sure someone with tons more knowledge will post.

Yes! Variable Frame Rate.

TMPGEnc works best for me.

Also, some players get their timings via counted audio samples, but if audio is VBR, it'll throw them way out of whack!

Why do people screw things up with crap like Variable Frame Rates?! That's gotta be the stupidest thing I've ever heard.

Makes it a pain in the ass to re-encode.
