- Pick a video size.
- Make the video and download it.
What happens to the audio?
The uncompressed WAV is encoded to AAC at 192 kbps inside the MP4. That is the format YouTube and Instagram expect, and it keeps the file far smaller than the WAV while sounding the same.
Good to know
The video uses H.264 at 2 frames per second, which is all a still picture needs, with AAC audio at 192 kbps. The result is barely larger than the audio file and plays on every platform. The video ends exactly when the audio ends.
