I've always noticed that there is a massive difference between the output of PhotoView 360 (a SolidWorks' add-in) when rendering an animation vs when rendering a still image.
The image below shows both outputs side by side (click on it to see it in its full size):
The top-right part is the image, while the bottom-left part is a frame from the animation.
Notice how the animation's rendering is extremely noisy when compared to the image's clear rendering.
I also want to mention that both renderings were made with the same settings and dimensions, so that isn't the cause.
I'd like to hear your thoughts about this issue and whether you've found a workaround for it.
