Video with separate video mask

I have a video shot on green screen with a matching mask sequence as a separate file. Is there a way to do get the video mask to mask the correlating video?

Or are these my only options:

1. Go to AE

2. Render out the two mp4 videos to create an alpha channel and re-import to Ps as one video file

Thanks!

You seem to already know that After Effects is the appropriate Adobe application to edit greenscreen video so why do you want to do it in Photoshop?

What do you mean by

matching mask sequence

exactly?

Could you please post screenshots?

Because it's a 360 image that will be rendered as a video. So it'll be static, just with people moving in it.

Skipping AE would just save a little time as the image will be edited in PS (and easier to match colors/lighting with composited people).

Doesn't look like there's a way around AE, which is fine, I just wanted to save some time, if possible.

Thanks!

MP4 can't have an Alpha channel, so this makes no sense to begin with. If at all it would have to be a CoDec that supports Alpha channels like Quicktime Animation or an image sequence in a suitable format. And yes, you have to do it in AE. PS has no way of using an external matte unless you plan on making your life difficult with the Frames mode in the timeline and mucking around with tons of layers and layer masks.
