how to make something like this?

hi i was wondering, how do you ‘‘sync’’ an audio to go with an song just like this; or where they make the audio go with the music, hope you understand my question and thanks in advance!

No, sorry, I don’t understand your question.

You don’t sync the audio to the video, obviously. The audio plays and you slide around various doggy clips until it looks like the dog is in sync…

You would need loads and loads of doggy video to start with. And then you need to take time to assemble it in a video editor.

There’s no magic wand in Audacity that can do that.

Slide around, but there appears to have been one clip i wasnt expecting a wand but rather the prosess
