Context
My problem started with a partial lack of sound in my rendered file. The WAV
audio strips were missing from the output, while the AAC
audio from a .mp4
video file was present. Everything is audible when editing.
There are some related questions which taught me that it's a problem of codec selection. This one and its answer motivated my further investigation and my question: I can't render audio with my video
I had the following for the output settings because I thought MP3
is a good selection which would work on all computers (I am using Blender 2.77 on a Ubuntu 14.04 derivative (Mint) and I have libmp3lame
installed)
I solved my problem by changing the Audio Codec to AAC
.
I am looking for:
- Explanation of why with
MP3
output theWAV
sound is missing but theAAC
sound is audible - Understanding the differences between selections in
Output
section:MPEG
vsH.264
since these seem to be the most common. Other formats are welcome :) (Frame server
,XVid
,AVI Raw|JPEG
). - Explanation of
Encoding > Format
andEncoding > Codec
options, in relation to point 2. For example, why are you able to chooseMPEG
output andnon-MPEG
format andnon-MPEG-non-<format>
codec? This is VERY confusing.
I hope I won't be closed as being too broad, I tried to be as specific as possible.
I realise this may not be a blender specific question. Please advise where to look for additional information.

Some of these are experiencing problems similar to mine (lack of sound) and usually due to a misconfiguration of Output
and Encoding
sections. However, even those that are solved give a very specific answer and are of little help when you're problem is slightly different
