Just checked mine and 24f defaults to 1/24 as well

I edited the video in Vegas before I converted the video to 24p in MB and that helped me get the slow-mo effect I wanted later. Only after each scene was fully edit, then I converted it to 24p. |

I think Bob was talking about his GL2. Magic Bullet does a great job of deinterlacing and converting to 24p, but you still get some of the pulldown look, versus the smoother, steady motion of native 24p shooting. Magic Bullet and Nattress effects seem to do the conversion better than anything else (for the money), in what I've seen.

What you may be seeing is frame judder. This is a byproduct of 24 frames per second which is noticeable particularly during pan shots of exteriors. You see this in not only digital but film during pan shots.
I hate judder. To avoid it, when shooting a project in 24p, shoot your pan shots in 30p. My experience. |
The nature of 24F
I wast testing the capabilities of 24f the other day and I found out that even though I was using High shutter speeds (above 1/48) to avoid frame judder I still see some when the person moved, I was filming straight at a person without paning or moving the camera. I noticed this everytime the person made gestures or moved her head. My question is if this is the normal nature of 24f ?
Oh in case you guys need to know I shoot in sd mode 24f, I edited the video in vegas 6 using the 24p sd template for wide screen, reder out to the 24p mpeg setting for dvd architecht so I could watch it in my tv. Thanks |
Has anyone shot 1080 30fps with a high shutter speed to get that action look? It would be real nice to see what the results are for people like me who shoot more action shots in brightly lit conditions. I guess I'll have to invest in some ND filters to knock some light out. Can you fit any filters behind the lens hood? Thanks for your time.

To avoid jitter you will probably want a slower shutter speed, not faster... For most things you would probably want a little bit of motion blur... A high shutter speed creates a "stop motion" effect... That is what is partially creating some of the jitter... May try 1/24 1/48 1/60...

Going higher than 48/60 shutter speed will introduce a new type of judder even at 60i.

Alain, a shutter speed higher than 1/48 may cause some strangeness, just as does a speed higher than 1/60 for NTSC interlace video.

I shoot at different shutters speeds including 1/48 and I still notice it. It is not that noticeable like it bothers but is there. It's really hard to explain, I'm new to the 24f world so probably this motion is normal. I thought it would look smooth as a real movie made with a film camera. I just want to know if this is a characteristic of 24f and how smooth the movement or motion should look compared to film ?. Thanks |

You have shutter speed (1/12 sec) and 12 fps. At 1/12 sec shutter you get blur. At 12 fps you get high speed or if you duplicate every frame you get an stutter effect. Quote:
The trick to use a frame rate other than 60i is to keep your moving subject in the same spot on your lcd or viewfinder. If you concentrate on the background while seeing a movie you'll notice motion blur also. |
Any one else could explain how smooth 24f should look ?
Thanks. |
