I need to convert image and audio into avi video files for use with a video mixing tool that only accepts avi video.
How do I:
- convert mp3 audio to avi without video channel
- convert jpg image to avi without sound
Without unnecessary re-encoding, if possible. Also, I think I can use black background image as an input, but I'd rather do without video channel altogether, if possible.
I would prefer a simple command-line solution, if possible.
