MeGui video length problem

[killerteengohan]

ok I ripped an FLV file from a website that streams videos. I used FLV Extract and extracted an h.264 video file and an aac audio file from the FLV.

now if I just take both of those files and mux them together in mkvmerge I get a 20:52 long video that works perfectly. The audio is in sync and it plays fine.

The video quality looks like crap though so im trying to use MeGui and AVISynth to improve the quality of the video. so I use the file indexer in megui and select the h.264 video file and it creates a .dga file. Once I have the .dga file I use the avisynth script creator part of the MeGui program.

ok now here is where the problem is. I havent even done anything to the video yet or added anything to the script yet and MeGui is saying my video file is 25:01 in length in the preview window when its not. Somehow the preview is playing it just fine and saying its 25:01 but its not. The original h.264 file is only 20:52 in length.

The audio file is only 20:52 in length and MeGui is trying to make the video 25:01 for some reason. I cant get it to keep the video the same length of the original video or audio for some reason and it wants to make a 25:01 long video file where the audio stops playing at 20:52

I have my script all written out and the video fixed perfectly but that length thing is an issue.

I tried adding AssumeFPS(30000,1001) to the script and the length in the preview changes the video length to 41:44. I tried changing it to AssumeFPS(24000,1001) and the video length in the preview window goes up to 52:10.

whats up with that?

I tried adding SRestore(23.976) so it was like this

SRestore (23976)
AssumeFPS(24000,1001)

and the video length goes back to 25:01 again like it was before I even added anything to the script.

I tried this

SRestore (23976)
AssumeFPS(30000,1001)

and the video length went down to 20:00 in the video preview. Thats 52 seconds too short now.

no matter what I try or attempt to change the script to I cant get this damn thing to show up in MeGui preview at its original video length.

Whats my problem here?

The h.264 file can be downloaded here if you need it to tell me.

I just tried

SRestore(25)
AssumeFPS(30000,1001)

and it went to the exact length its supposed to be in the video preview. I guess I needed SRestore to be 25FPS because thats what the h.264 file was originally?

FLVExtract says the FPS was 29.97 and when I mux it in mkvmerge and tell it 29.97 so it doesnt assume 25 and it works perfectly. mediainfo says 25FPS though even though I told it the video was 29.97. thats where I got the guess from SRestore(25)
