i shot a short movie and i am getting trails when people make movements...

Just an idea. Lay down another video track, and copy paste that footage above it turn on your opacity to half. Then make the top track out of sync by a second.
 
i didnt really notice any trailing per say, but i saw something of the effect of using a shutter speed of 1/48. Try upping your shutter to 1/60 and see if that makes a difference. Using 24p also produces more of a motion blur than 30p or 60i but that gives it its effect i find.
 
A 1/48 shutter speed won't leave trails. It will be indistinguishable from a 1/50 shutter speed. I wonder if it's just how it's being viewed on your computer. Have you tried viewing a digital cut on a regular TV monitor? Or on a burned DVD on your TV? You might find the "blurring/trailing" is actually a function o fyour computer screen? Just a thought.
 
I noticed it on the close up of his head. I have no idea what is wrong. Like it has previously been said, a 1/48 shutter speed should be fine. Just as a test, try recreating a similar shot with varying shutters, both slower and faster. You never know what you'll find.
 
When I shoot footage at 24P (Normal) at 1/48 shutter, I get the strobing effect of course, but I notice trailing as well. You're not the only one. I edit with Vegas 6.0 (I'm no expert, I'm just getting into this) and I find that shooting 24PA with a shutter of 1/43 and captured into a 24P timeline, it looks a lot better. However, you should test your footage on a progressive scan TV (LCD or Plasma) to view optimal results. I don't really understand why it would "trail" viewed on a computer, though. Try changing your settings. I'm not quite sure how you'd fix this in post, I'm afraid.
 
Be aware that switching the shutter from 1/48 to 1/43 only "blurs" the strobing effect. I don't know if this would help any. Are you using focus assist?
 
..... My computer won't load your clip. (Yay, Dial-Up!) Well, I can't say for sure what the problem may be. Just experiment with it. With 24P, motion blur is inevitable. With proper lighting, the right shutter speed, and choosing between manual focus and focus assist, you should be able to achieve what you're going for. I'm interested to see if 1/60 is the way to go... I guess I'll have to grab my DVX and see! ;)
 
great..thanks!! i'll try different settings till i get it right. i really should get barry's book!
ive put it off for so long. just broke lately.

Your problem is simple. You have 24p footage rendered out as a 29.97 fps Qtime file. Now if this was shown on an interlaced television, you would not notice the trails, but since this is shown on a computer monitor, the trails are apparent. Simply output a 24p Q-time file, using the correct pulldown method, and your trails will dissapear.

Yes, and make sure your entire project is set up correctly... you may just be editing in a 29.97 timeline in which case you need to change that to 23.976. Which NLE are you using?

using FCP..but i thought if you shoot in 24p(regular)you just capture like normal..(29.97)
only if you shoot 24p(advanced)..then you change capture preset..

hmmm.
 
can you briefy describe this process?..sorry!

can you briefy describe this process?..sorry!

can you tell me the steps in FCP??
please..
 
Sorry, not a FCP guy, but if you are editing on a 24P timeline simply export to a quicktime codec and make the framerate 24fps.
