Rendered a .MP4 from Camtasia Studio 7, audio format most likely PCM (its what I recorded it with).
When I put the .MP4 into my one-click encoder set to x264 (MP4) and Nero AAC, it got past "Muxing MKV" (first step) and then the worker closed suddenly and there was a red x on the tray icon. Log file (included) said "Error Code: 1" near the bottom.
tried making a AVS script, which was successful, and hit AutoEncode. It went all the way through but the source video, (filename)_muxed it was named, had no audio. Changing audio settings did nothing.
I then got an old build (2153 x86), did the same one-click encoding settings and it worked and created a working video.
I then also got an .avi file and ran it through 2418, that also completed and gave me a working file.
Apparently, 2418 is having problems handling audio files from Camtasia Studio 7 in PCM format.
Please upload such a file.
Does this problem still exist?
