Issues when recoding Fraps recodings in Avidemux 2.6

Hi everyone,

I've been using Avidemux for quite a while now to cut and recode my DVR recordings. Except from occasional crashes due to the OpenGL preview issue it has served me well so far.

This weekend I was going to recode a fraps recording which simply uses way too much space in its raw state. Since I hadn't updated for some time I started with Version 2.6.1 (64 Bit).

Compressing to MPEG4 AVC (x264)/AAC (FAAC) 192Kbit/MP4: I got the "Too short" error
Compressing the exact same footage to MPEG4 AVC (x264)/MP3(lame) 192 kbit/MKV: The recoding finished but completely messed up the audio track. It became noisy and very low pitced - it sounded as if it was slowed down by a factor of 2 or more during the recoding process.

Due to the issues I decided to update to the latest version 2.6.5 (64 Bit)
Now I do not receive the too short error anymore but Avidemux seems to completely ignore the bitrate limits producing a file that is basically as big as the raw footage, even if I set a constant bitrate of 2000 kbit/s I get average bitrates between 35000kbit/s and 200000 kbit/s. On some recordings the new version of Avidemux also just freezes once I try to save the file.

Since the Fraps recordings are _really_ big I've not yet provided a sample file because it will be just faster to download the fraps trial version (3.5.99 - Build 15618) and record like 5 or 10 seconds of anything. If required I will upload a sample create by me, but the upload will take quite some time I guess.

P.S.: Playing the raw footage in VLC works with no issues audio seems to be present, complete and sounds nice.

Hi mean,

I downloaded the file you linked here. VirusTotal is reporting a trojan inside and my virus scanner sandboxes it and says it's trying to perform suspicious operations. Could the file be contaminated somehow?

Okay sorry for the paranoia but being a Windows user you have to be careful with binaries linked inside a forum. I tested the 32Bit nightly build and its still the same issue, the average bitrate goes to the roof and the resulting recoded file are huge.
