I'm trying to use Ubuntu Linux 19.04 to convert an OpenShot video into a more efficient file-size.

The video only contains two still images, and 20 minutes of audio, but for each file-type I save-as, the output-file is larger than 600MB.

Apparently I'm choosing the wrong lossless output file-type; you'd think a video like this would only be 10MB, since almost all the frames, in the entire video, are one of two frames.

Using ffmpeg, how can I convert this video to a format that understands how to compress all the duplicate frames efficiently?

Your question is answered in the ffmpeg examples. You can use something like this:

ffmpeg -loop 1 -framerate 1 -i banner.png -i audio.wav -map 0 -map 1 -c:v libx264 -crf 16 -c:a aac -b:a 92k -shortest -movflags +faststart ready_to_upload.mp4

Detailed explanation:

• 
  -loop 1 repeat image potentially forever


• 
  -framerate 1 have a low frame-rate


• 
  -i banner.png -i audio.wav input image and audio


• 
  -map 0 -map 1 use both stream


• 
  -c:v libx264 -crf 16 have high-quality image


• 
  -c:a libfdk_aac -b:a 92k have high-quality


• 
  -shortest stop repeating banner image when audio is finished


• 
  -movflags +faststart include index at beginning of MP4 container for early start

It compresses to approximately 1 MB per minute.

Note: YouTube is likely (but not guaranteed) to re-encode your video. Image quality will degrade.

  Sorry, my mistake, there are actually two images in the video. The image changes near the end.
