Gaming Steam Video Overlay

I am launching a stream on Facebook Gaming using Streamlabs OBS called Attic Gaming.

I need a stream starting introduction animation / video that will be played through StreamLabs OBS before each stream along with an intermission screen.

Some examples I like can be found by watching a video on the below:

I already have a logo made which makes the A look like a ladder. I wish to carry this on in the animation, with the logo being displayed and then the animation of climbing up a ladder. It should be on a continuous loop.

The intermission screen should follow the same theme and then also have space for camera, notifications and video screen.

I'm unsure on what the file format needs to be to be able to upload it to Streamlabs, hoping you can check this out.

Any questions just let me know.
