Slow motion blur

I'm working with some clips that I have slowed down to about 50% speed and I am getting some major blur. The clip is of some realativly quick motion, which I'm sure is part of the problem.

I looked at the tutorial for encoding fast motion and that helped some, I'm going to continue tweaking it, but is there anything else I can do when working with slo-mo to keep this kind of thing from happening.

I thought I had seen a forum topic on this a while back, but can't seem to find it now.

I'm using MSP 8 with hot-fix, and the clip properties are Frame-base with the reduce jitter (or whatever its called) box checked. I had it on deinterlace before and it seemed to be worse then.

Thanks for any help you're all able to give.

No takers? Have I stumped the entire board?

If you tape a fast acting object at normal frame rates, each frame is blurry. Slowing it down will not decrease the blurr.

The only way to overcome this is some advanced planning. You'll need to tape the action with a lot faster shutter speed, not every cam out there allows for that.

However, if you then don't slow down these clips, the motion will look jerky and you will have to add some motion blurr to them. At a reduced speed, because the motion takes place slower, the clips will look ok.

It's purely physics, nothing anyone can do to change that.

Perhaps I wasn't clear...

I wasn't trying to slow them down to reduce the blur. The 50% speed was for dramatic effect. I also failed to mention, foolishly

, that I had added a Pan&Zoom filter to some of the clips.

However, I just found one of your earlier posts about adding the blur and that helped some of them, and I used a Moving Path instead of the P&Z filter and that helped as well.

THanks for the input.
