Adding GIF/MP4 as boot screen

Question

so im in a lenovo legion laptop, ive succeed changing the windows startup screen as custom using hackbgrt, but hackbgrt only supports bmp file, while i want a custom gif/mp4 for the startup screen, is there any way i can inject a gif/mp4 as the startup screen? i know alot of you will answer using vlc in task scheduler as startup BUT that wont work as it only plays after the logging in screen, so, any workarounds?

Answer 1

Sadly it is not possible to add a gif or any video file format to the PC boot process, even if you use HackBGRT, it is only possible to add an image file.

The BGRT (Boot Graphics Resource Table), only supports a single, static image, it relies on basic UEFI graphics drivers.
