It looks like it's recording the full frames but is capturing a larger image than the game resolution so at the right and bottom, it just repeats the pixels. All you should have to do is crop the recorded output.
This is probably happening because you start Quicktime recording outside the game so it will capture your desktop resolution or maybe a preset size and when you enter the game, the resolution changes to a lower value.
You can try changing your desktop resolution before starting the game or increasing your in-game resolution to match the recorded resolution or just keep the same setup and crop the output.
