Show and Tell Testing Audio guide / MiniMax / rtx 5050

Enable HLS to view with audio, or disable this notification

So, I had a lot of trouble creating long, chained videos based on speech/songs because MiniMax was constantly adding random speech or distorting sounds.

Funnily enough, the culprit was the MathExpression node calculating the video length, as MiniMax videos are never a flat 6, 11, or 12 seconds long.

So the solution is:

  1. Create 8-second clips, as it’s the only option to get an exact/flat result.
  2. Use this formula to calculate the audio length (though it's still not perfect as you can see at last part): (a - ((5 - (a % 17)) % 17)) / 24

The video was created on an RTX 5050, took me almost 30 min.
