Media plates video frame size limit

Development Asset Creation

Hi,
I’ve added multiple media plates to my level (Unreal 5.3)
1920x1080, 4096x2000, 5000x2000, 6000x1080, 7600x2000

with Play in Editor, they all work fine (though, I found that bigger than 7600 wide does not work)

However, after packaging, only the 1920x1080 works. The rest are blank.

Is this intended behaviour, a bug, something I’m not doing?

Note: ALL video files are loaded into UE from “Content\Movies”
This dir is also added in the ‘addition non-asset directories to package’ (from project settings)

Any help, massively appreciated! :slight_smile:
Thanks,
Graham

After many many more package tests, I’ve transitioned to testing via “standalone game” to increase iteration speed (instead of packaging every time)
“standalone game” mode also exhibits the non working video.

I’ve been tweaking every parameter I thought might make a difference in the mediaPlateComponent.
Nothing seems to make the video play.

However, in roughly 1 in every 10 plays, miraculously the video works!!!

I then hit escape to close gameplay, and without changing anything, play again. Now it doesn’t work.
So, it seems to work randomly!!!
