Thanks for pointing this out! After looking at your functions and reading the headers, i think i will use Trim3.

You really like Assert, i had to go look it up.

So reworking my first example it should be something like this

function CutFrames(clip c, int start, int end)
{
	return c.trim3(0, start) + c.trim3(end, c.Framecount())
}
