Performance comparison for Godot 4.0's Movie Maker mode, depending on the MJPEG quality chosen.

• Godot version: 4.0.alpha14
• OS: Fedora 36
• CPU: Intel Core i7-6700K
• GPU: NVIDIA GeForce GTX 1080
• SSD: Samsung 850 EVO (1 TB)

In this project, the output generated by Godot's Movie Maker mode is a 1-second video at 60 FPS (therefore, with 60 frames). The resolution is 1024×600, and all frames are identical. Since MJPEG does not feature inter-frame compression (only intra-frame compression), the file size is identical regardless of how much motion is present in the recorded video.

A WAV audio channel is also saved by Godot in the AVI file, as this can't be disabled in the engine.

The time taken to save the video (in seconds). A save time of 1 second means that the video could be saved exactly in real-time speed. Lower values than 1 second mean the video was recorded faster than real-time, and higher values than 1 second mean the video was recorded slower than real-time.

Lower is better.

The perceptual quality of the video's first frame. A value of 0 indicates perfectly lossless output, with higher values being increasingly different from the lossless reference image.
