Convert an mp3 into a video.

Requirements:

• Bash for the scripting (should come with and be default on most distros)

• cat for merging the mp3s (should come with most distros)

  • I’d love to replace this with cp, but I don’t see how that’s possible.
  • I could (should?) replace it with mp3wrap for better audio quality.

• LAME for working with mp3s

  • I tried replacing lame with FFmpeg, but it doesn’t get things right.
• ExifTool for learning the duration of an mp3.
• xxd for dumping binary into text and back
• FFmpeg for working with videos

• See:

  • Convert an image into a video, using FFmpeg
  • Determining mp3 duration
  • Merging mp3s
  • Resize a video for YouTube, using FFmpeg

The script: merge-mp3s-into-a-video.sh

Todo ∞

• merge my ffmpeg commands together..

• Can I just use ffmpeg to merge multiple mp3s into the video?

  • Should be possible, maybe if I specify multiple -map or delay or whatever commands somehow?

• followup: get the length and filename of every mp3. Ignore the first three characters of the filenames. Build a subtitles file which shows each filename for the appropriate length of time. Then hard-code that subtitle into the video.
