What's the difference between "Performance Videos" and "Live Performances"?

Quote from bethesda

What is MR and AR, and what's the difference between "Performance Videos" and "Dance Practice"?

MR = music recorded, basically just instruments and no voice

AR = all recorded, so music and voice

Performance videos can use both MR and AR, with AR sometimes being lip-synced. Or with cuts in it to allow for live vocals. But, there are very few that can do it.

Dance practice is usually just MR and them dancing. Then you have fixed camera, or moved camera.

I know it sounds complicated, but its not. It depends on the capabilities of the group and the company.

There are companies that focus more on performance than voice, some who focus more on voice and so forth.

But dance practice (used to be) them actually practicing. Now its all polished.
