Can you share with us your project settings. Did you edit this on a 60i or 30p timeline.

Then maybe you did something wrong during the recording process. What was your shutter speed. You should use high shutter speeds.

Look at this video. This is one of the best examples of how HV20 handles slow mo. No ghosting what so ever.

What editing software are you using, and what procedure are you following to make it slomo?

Don't use auto mode for specific purposes. It is for general use. If you switch to P mode, lock your exposure and use TV mode which lets you set the shutter speed, you can achieve much better results.

For slow mo yes, the higher the better. In 60i mode, at least make sure it is not less than 60. But the catch is higher shutter speeds require more light, so it may not be suitable for indoors. But in your case I don't see if this is going to be a problem. I am not familiar with Ulead video studio so I cannot comment on that.

For those of us who don't have or use this software, can you detail what those are? Hard to help you if we don't know what you're doing.

As an example, when I'm using Premiere, there are several different ways to get slomo, and according to the experts they all have differing results, quality-wise.

From the look of your clip, it appears you may have a frame blending or field reversal issue, but hard to know for sure.

While some people say to use higher shutter speeds for better slomo, others say never to shoot at anything other than 1/60. I'm not sure who's right. I shoot all my footage at 1/60 and don't have the issues you have with slomo. For sure at higher shutter speeds your video will have that stuttery look, because you actually want that motion blur to make your video look smoother at normal speed.

im sorry i cant be of more help but my program just says playbback speed with a little bar that you can drag back and forth to set the speed you want and thats all it says, but your saying its debatable as to if higher shutter speeds will take away the ghosting? im not sure what you are saying

You meant frame rate I guess not shutter speed. 60i is the frame rate.

i did few slomo tests at 24, 48, 60, 100, 250 etc and it almost seems once you get past 100 it gets choppier, it seems like 48 or 60 is the best speed

Use 48 for 24p mode and 60 for 60i mode. You will get better results.
