whenver I use AAA in my script, the file comes out like this?

I'm not really sure why, does anybody know? I posted something about this once before I think. I decided to re-post it because I found out the problem came from the aaa filter in my script. Can it be fixed? The resize in my script is correct Spline36resize(720,540). Do I need to adjust the aaa script or settings or something? the filter is called aaa or animeantialiasing

Add AssumeFrameBased() after AAA().

Thank-you so much! This filter is exactly what I need for my source!

I don't know why it happens. But some encoders decide to double the frame height for some reason.
