Video playback at accelerated speed

[ChibiBoi]

I'm trying to play a .avi file that's encoded with DivX 3.1alpha with Nandub v1.0rc2 and should playback fine, but when opened in MPC-HC, the video plays at super speed, while the audio remains at a normal speed. When I played with VLC Player, the video was fine but the audio was stuttering and hardly playing. When I played with DivX Player Plus, the video was fine but the audio was player at a slower rate and not synced properly.

I'll try to upload a sample when I get the chance to, but do you guys have any idea why it's like this? Maybe it was improperly encoded?

When I open it in Nandub, at the bottom where it tells me the duration of the video, it says [K][4x] but sometimes it'll jump to 7x or 2x.

Have you checked the video headers with mediainfo? Especially the framerate.

You can try remux it with virtualdub (and maybe set the exact frame rate). Open video, under video and audio choose direct stream copy. File->Save as new avi. If still same problem then try set a frame rate under Video->frame rate and save again.

I think I found the problem. I opened it with VirtualDub and it said the audio was improperly encoded (64kb/s ABR Stereo), I got rid of the audio and the video played just fine

I've had that happen before. I think it's something to do with the player not getting the audio sample correct which causes it to play the file at the wrong speed..... or something like that. I recall one occasion where it'd happen even if the audio wasn't muxed into the AVI, but both the video and audio would play correctly on their own. I extracted the audio and resaved the AVI without it, which played fine, then I gave the audio the same name as the AVI and put it in the same folder, and opened the AVI with MPC-HC again. As MPC-HC was set to auto-load external audio, that'd cause the problem to return.

It was a long time ago, but I'm sure it was something to do with the audio sample rate being displayed, which seemed fairly unusual and I assumed was incorrect.... but I can't remember exactly..... I probably just gave up and re-encoded the audio.
