VR Fractal Noise smooth in editor, stutters after export

I'm a Premiere Pro newbie creating a standard (non-VR) 1080p video using static images. I've added a layer of color in the timeline which I animate using the VR Fractal Noise effect (I love the string fractals!).

The issue is that while the fractal animation is smooth in the editor, once I export it to video it seems choppy, like the frame rate of the fractal effect has dropped to one or two frames per second. Maybe I'm just seeing the results of the video codec? (Animated gradients that look smooth in the editor display serious banding once exported.)

Again, I'm not trying to create a VR video, rather I just like the effect of the VR Fractal Noise. Any suggestions? Thanks.

Export settings: H.264/YouTube 1080p Full HD
