Why render this way?

[#1]

I need someone in the house to help me please.

Why do my final rendering output always have a wave line whenever i render with h.264 format, and how do i correct that? How do i make a smooth rendering?

Zoom in this picture below to see what i mean.

Post a screenshot of your export settings.

I can't figure out what the 'wavy line' is? Is it just the natural lack of definition of everything?

Your source and sequence settings are both for basically SD, like the old TV standards, so if you then 'blow them up' to say fullscreen / HD 1920x1080 the scaling that involves will make for the jaggies you are seeing.

Why is your source footage so small?
