Black Glitching on Render; Project View Works

Hey gang—I am having an issue on my renders (see attached image). I know this has to do with the technique I'm using, but this is a new issue and I suspect some sort of setting got messed up during an update. 

I'm taking jpg sequences, and the shots are kind of related, also kind of not; I change the frame blending to pixel motion, enable time remapping and stretch the length to about 1000%. The effect is quite dreamy and strange, which I like, and it works perfectly in the comp viewer, but when I render it out, I get the attached image. 

I've tried using Animation and all the ProRes varients.
