4k + Alpha channel = very big size

Hello there,
I’m having a very large size when making video with 4k resolution and alpha channel. 4.5 GB for 30 seconds.

Is there a way to compress this more?

Render the alpha channel as a separate black and white matte.

Can this method be used to upload to VideoHive?
Is not it difficult for the person who uses the video?

A bit, but that’s the only option aside from reducing the resolution, shortening the duration, or not having an alpha channel at all.

I will have to explain how to use matte video in the description part, right?

Yeah that’s the way to go.
