How Can You Slow Down Footage Without Ghosting?
Hey everyone, I have a new question, everytime I go to the edge of a clip and i hold shift to either speed it up or slow it down and view the clip frame by frame I get the ghosting effect.
I was wondering, is there any real way to slow down footage without getting this effect?
I ask because I am going to get old film reels transferred by Pro8mm and they do it to 24 Frames per second 1080P, but I assume that those reels were recorded in 18 frames or maybe even less…
So the guy told me regardless of the frame rate if they convert it to 24 frames I wouldnt be missing any frames all of them would still be there(would it though?) and so he told me this will result in everything moving very fast if it was indeed shot at a lower frame rate, so he told me all I would have to do is slow it down in vegas!
I immediately knew I would probably get the ghosting effect because thats what happens when you slow something down!
I dont want this to happen to these old tapes I will be paying lots of money to get if the end result comes out with ghost effect frames, does anyone know if there is a way to slow something down without the ghosting and if not, what do you think I should do?
Thanks

Right click on the video event on your timeline and click “Disable Resampling”, which makes Vegas drop frames instead of trying to blend them to create slow motion.
Though I haven’t used it, a plugin like Twixtor is supposed to smooth out slow motion footage.

Angelo is correct, I disable resampling in all my work.
It softens the quality of your final renders, (that isnt good).Steve Rhoden

I have a copy of twixtor and am getting my head around getting good slow motion as well.
Twixtor does a fantastic job of producing intermediate frames for slow motion, provided that the footage meets the design criteria for Twixtor. It is a pixel vector mapping application which tries to determine where the pixels are traveling from frame to frame and then positions them accordingly.
If you have footage which doesn’t meet some fairly strict guidelines, it will produce a very horrible output (lots of warping artifacts). To produce good “Twixtor” slow-motion shots, you need to lock the camera position, so that you get minimum movement of background elements, you need to ensure that most of the movement stays within the frame and a number of other strict guidelines. So I would recommend that you trial the software before trying to use it on your specific project.
As many other people have pointed out, Sony’s frame blending solution does not work for blending “double speed” frames, ie, 60fps in a 30fps project, or 50fps in a 25fps project, etc. It ghosts the frames for no apparent reason and looking back in the forums, has always had this behaviour. So it back to “No Blending” I’m afraid.
