Also I don't see FPS limiter running when I launch with your script.

You wouldn't see it running in anything other than task manager, it's running hidden. If it's not showing up in task manager either, check what happens when you run the fps limiter exe directly.

I can't test at the moment, but I'm guessing this should work to combine the scripts:

Run,fpslimiter32.exe,,hide
Run,Valkyria.exe
Loop {
	Sleep,1
	PlayingMovie := 0
	Loop,Files,movie\*
		{
		FileMove,%A_LoopFileLongPath%,%A_LoopFileLongPath%
		if (ErrorLevel = 1)
			PlayingMovie := 1
		}
	if (PlayingMovie = 1)
		SendInput,^{Numpad0}
	if (PlayingMovie = 0)
		SendInput,^{Numpad1}
	Process,Exist,Valkyria.exe
	if (ErrorLevel = 0) {
		Process,Close,fpslimiter32.exe
		ExitApp
		}
	}
