.i hope somebody can help

I want to be able to (via obs) MacBook Pro 2019 64 ram

Play a media source with video and audio

Use a usb camera to record myself on a green screen dancing to the media source track

The important part-
I need to be seen dancing to the track without any delay as I would be off beat. So I also need to hear the track

This is would the be using ndi to take into a zoom call via obs, into virtual input and then capturing audio and video ndi in zoom.

On other occasions I would be recording this and on others I would be streaming into YouTube

I do have loopback if this helps too

I have been testing for 2 days and cannot work out the secret sauce.
I have search and you are the only guys who come. Close to helping but my scenario is slightly different to those I can find.

So the overall plan is to be able to stream acts into zoom. Some will be on green screen so i would have a virtual background changing to music and my moves would need to be to time. Also if o was to spark or sing that would also need to be to music

My mic is a usb mic if that helps



On one final test yesterday I have a media source with audio playing with my video from usb capture, and my usb mic

All into loopback and zoom audio input was loopback

Media source music And video perfectly in sync anytime

I monitored sound from loopback into EarPods (but ideas would be to a speaker in the room when I don’t need to use the mic
Then
My video cam and mic via obs-loopback -zoom
—Mic out of sync with me speaking
—when I clap to the beat my video out it sync with the media source music

If I then take my mic direct into loopback then my mic and video (cam) are in perfect sync
But doesn’t solve the problem my can video being out I’d sync with the media source video and audio
