Hi Community,

Is it possible to isolate a person rapping on stage? The reason for this task because the footage wasnt shot well and needing to isolate the person to keep her on a transparent background with her rapping audio.

 

Any good turtorials I can follow? The edit is on Premiere although I figured for the task is best done on after effects.

 

Many Thanks

Thank you, it is exactly what I am after.

I spoke to the director that I am working with, she doesnt want the actress cut out but shes in focus while the background is blurred.

I tried it with the new masking tool in premiere beta and it works, I love this tool as it works in seconds while the other tool in After Effects it takes hrs.

I'd start with rotobrush in After Effects.  You can draw around a person and then monitor as it updates frame by frame.  You'll probably have to stop it from time to time to adjust.  
The first part of this tutorial of mine covers rotobrush:

I also did a fun series where I talked my wife through using masks and rotobrush:

But you might also want to check out the new object mask feature in Premiere Pro that can cut people out from the background automatically
