After Effects Flickering

Hi everyone. I've searched all over the net but can't find an answer and I'm hoping someone here can help. I'm trying to animate a png of a waveform across the screen from left to right. As I render I'm getting this weird flicker in the thinnest parts of the waveform, even though it's happening less after I output to to H264. Here is the rendered version. 30 fps at 1080. Any ideas on what might be going on? Thx!

That's going to happen with really thin horizontal or vertical likes. You can reduce it a tiny bit with a small amount of blur, but you can't eliminate it.
If you're willing to change the speed of the horizontal motion, that will help a lot, too.

Thanks, Dave! Speed it up or slow it down?

It sounds like Dave is being facetious, but it's good advice. It might look better faster, it might look better slower. You'll just have to experiment to see.

Turning motion blur on for your layer and composition might solve it without you having to do anything, by the way.

It also wouldn't hurt for you to look into judder.

Thanks, guys. I tried both speeding up and slowing down but no love. Digging the post on juddering so I'll look into that for sure. Thanks to you guys for your insight!
