Speed change isn't blurry in the canvas but it is blurry when exported

I have a video using all HDV footage at 29.97 fps and I've slowed it down to 58% and I've taken off Frame Blending. I'm familiar with how this is supposed to look, and It looks fine when I play it in the timeline, but when I export it out as a Quicktime movie it is very blurry, considerably more than on the canvas playback. Also, there's an extreme color correction effect applied to all the footage as well and it becomes extremely muted when I export the footage.
