Can I change the audio track/song used in my music video?

You can of course, you simply need to create a new version (https://help.rotorvideos.com/hc/en-us/articles/360001841998-How-do-I-edit-a-video-before-purchase-)

You will then be asked asked to confirm you are happy with 3 items (which are carried over from your previous render)

1) Audio
2) Clips
3) Style

To change your song, you simply need to replace the audio track in step 1.

However, our AI uses the speed, tempo and intensity of your song to know when and where to make cuts. As long as the replacement song is 99% similar to the first version, the end result should be almost identical.

However, if there are significant deviations... you may notice deviation in how the new video looks/feels when compared to the original.

E.g. A live version of the same track, might create a video that looks and feels quite a bit different.
