Try updated version: https://github.com/Magisk-Modules-Alt-Repo/video-to-bootanimation/releases/tag/V8

• Make sure your /storage/emulated/0/cfg.txt is in this format

# video2boot configuration file
# Lines starting with # are ignored. Empty values = auto-detect.

# Optional custom video path
video=/sdcard/bootvideo.mp4

# Optional output resolution
width=1080
height=2400

# Optional frame rate
fps=60

# Include audio from video (on/off)
audio=off

# Target install location
