I follow this tutorial how to create writing FX with hitfilm pro

The same concept can be applied in motion graphics, which is great.

Problem here it create that dirty white line at the edges, I've set feathering to 0. How do I get

rid of it?

I'm using VEGAS Effects, but its the same software with Hitfilm Pro.
