Understanding VMX Log Files

All VMX log files are stored in the following location:

vtaccess > VMX > ffmpeg_transcode

vtaccess is the home folder on the vmx machine. If you double-click your Macintosh HD icon, look for the house icon in the window that comes up.

NameOfProgram.audioextraction.wav.log.txt -- this file is the ffmpeg log file that extracts the aac audio from the downloaded MPEG-4 file and saves it as 'Audio.wav' in the 'MPEG2' folder

NameOfProgram.normalize.log.txt -- this is the log of the actual audio normalization. In this log file, you will see a line that starts with either 'Applying adjustment of' followed by the value it is adjusting, OR if the file is at -12db (like the bars and tone file) it will instead say 'Audio.wav already normalized, not adjusting...' at the bottom. This is where you will look to see what change gets made.

NameOfProgram.mpg.log.txt -- this is the ffmpeg log file of the transcode from MPEG-4 to MPEG-2. In the top section of the file, you can see what it's using for the video file and what it's using for the audio file.

NameOfProgram.mp4.log.txt -- thsi is the ffmpeg log file of the transcode from MPEG-2 to MPEG-4.
