View Full Version : 24p

Anyone know of a way to get rid of the blur that you get when filming in 24p with the HV20? I filmed a dance class of 2 and around the people you can see a blur around their legs and parts of their image when they more. They're not even moving that fast. Is that something that I'm gonna have to get use to or can I fix it in post or during the shooting?

Did you actually remove the pulldown, or are you talking about how the video looks like straight out of the tape? If you have removed the pulldown, then make sure you used an application that knows how to do that correctly, and also, to get better results, change the shutter speed.

No I don't mean the effect you get when with interlaced video. I mean like an actual softness blur. I converted the video to 29.97 mpeg to record on a dvd.
It's like a slight motion blur.

Well, if you filmed in 24f and then you re-converted it in 30fps, that can be the culprit... You could have created the DVD in 24p mode, after having removed pulldown. Also, it's kind of natural to get motion blur on 24p, because it has fewer frames than 30fps.
So the question still stands: after you shot in 24f mode, did you remove pulldown?

It could be a few things, if you don't do the 24p pulldown completely correctly then you can have some ghosting, or perhaps if you did do it right, it's because you put it back up to 29.97fps, but I dunno bout that.
Thing is, it is really dependent on what shutter speed you filmed at for motion blurs. I find 1/48 is best because 1/24 gives too much blurring and 1/60+ tends to be too dark for my tastes...so if you had it on cinematic mode without locking the exposure or something, it could have gone to 1/24 or 1/12 without you knowing.

I'm thinking it may have to do with the shutter speed, I had it in TV mode. I captured in 24p, which is really 60i with pull down. Then I converted that to mpeg2 720x480, so when I exported it to a DVD using 29.97fps it took care of the interlacing.

Yeah, I guess then you need to either remove the pulldown before you edit or burn a DVD, or the blame was on the shutter speed.

BTW, if you upload somewhere an *unmodified* straight from the camera .m2t clip that ain't bigger than 60-70 MB and shows the blur problem from that dance event, i can try removing the pulldown for you and see if that helps at all with easing the motion blur.
