Motion Blur Skipping Frames and Some Objects

Hi there,

I did some test renders using the Level Sequencer’s Render Movie Settings.
I have a Post Process Volume with Unbound checked, and I enabled Motion Blur with its default setting of 0.5 for Amount.

I looked through the frames and noticed that on frame 13, motion blur was absent.
Here’s a link to three frames that I rendered. There was a total of 50 frames.

I also noticed that the motion blur wasn’t being applied to the hand throughout the entire sequence I rendered.

Is there anything I can do to fix these issues? How do I avoid frame skipping for motion blur? And how do I make sure all the moving objects have motion blur active?
