I'm editing a video with a separate MP3 audio track. Everything works fine when I preview playback within the video editor, but the rendered videos have no audio. They have an audio track with the proper settings, but no actual audio.
My render settings are configured for "FFmpeg Video", with h.264 video and AAC audio. These same settings worked with another video I rendered recently, but not for this one.
If I try to use Render > Render Audio..., Blender seems to work on it for a few seconds and then crashes. The output audio file ends up 0-bytes, no matter the container.
I tried dropping in a random OGG audio file, but to no avail. I don't know what I'm doing wrong.
