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
I solved my problem by changing the Audio Codec to
I am looking for:
- Explanation of why with
WAVsound is missing but the
AACsound is audible
- Understanding the differences between selections in
H.264since these seem to be the most common. Other formats are welcome :) (
- Explanation of
Encoding > Formatand
Encoding > Codecoptions, in relation to point 2. For example, why are you able to choose
non-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
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
This one gives one choice that is working, but no explanation: Rendering Sound In Video Sequencer (duplicate https://blender.stackexchange.com/questions/47816/how-do-i-render-intros-in-blender-with-sound )
This one reports a problem when converting
MP3. It could be related to my initial problem, since both
WAV are lossless https://blender.stackexchange.com/questions/38850/script-for-audio-encoding
Maybe: No sound in VSE
