Exported AVI video has a corrupted header/metadata and cannot be played

[HaleyHalcyon]

Tested versions

• Always been reproducible ever since Godot first added movie writer

System information

Windows 10, Redot 4.3 stable

Issue description

When I try to export a video using Redot’s movie writer functionality, the resulting AVI file has a corrupted header and cannot be played. I’ve had to resort to writing a script to save a screenshot every render frame while movie writer is active, then deleting the resulting AVI file.

Steps to reproduce

1. use the movie writer functionalty to export a video

Minimal reproduction project (MRP)

This issue happens regardless of scene contents or complexity
