INDEXDSLR footage jumpy when panning
10 years, 4 months ago - Kyri Saphiris
I recorded some footage which involved panning. When I view the footage, the shot during panning is very jumpy and not smooth at all.
I had set my camera up at 24fps and used a shutter speed setting of 1/50s.
If anyone can advise why my pans are not smooth and what I can do about it that would be really helpful.
Thanks.

"Many advanced shooters welcome the inclusion of the 24p mode, which has pretty much become a standard feature for video-capable interchangeable lens cameras. This frame rate comes from the days of motion picture film cameras, as the de facto standard frame rate for cinema and as such, this is the frame rate movies have been shot in for many decades. Nowadays with video, the 24p frame rate gives videos the "film look and feel" that many filmmakers and video shooters want. It can be tricky to shoot in 24p however, as the lower frame rate can look choppy, particularly when shooting with fast shutter speeds or when panning quickly."
Watch a movie on the big screen - pans are generally slow (or choppy!) - it's a hallmark of 24fps progressive shooting, especially with a short exposure (which limits your motion blur).

The one constant in your tastes is the shooting rate.
Could it be that the frame rate you shoot at and the frame rate on your editing program are not matching?
Make sure you set your editing program to match other ways it will ad repeat frames automatically. In all likelihood your editing program will be set up to run at 25 fps (PAL) repeating a frame every second to make up for the missing frame you are feeding it as 24fps footage. This can come across as as choppy. Set your camera to run as PAL or your editing program to match your shooting rate ... or ... could it be that your tripod head is giving you trouble?

It's called rolling shutter and you need a serious camera with a global shutter to get rid of the issue. Slower movement will definitely help though.
Keep shooting!!

Sometimes firmware update can solve those though tilting and panning was never a good idea on dslrs.

Thanks for that. Very interesting. And you even remembered that I had a Nikon D5200! Thanks so much for taking the time to be extra helpful.
I tried several tests. In fact, I've done six tests so far, all with choppy movement. I tried two pans at ultra slow panning, took about 15 seconds to pan one side of the view to the other. And two pans at "normal" panning speed, still slow-ish, and two at slightly faster. All were choppy/ jerky.
Tried with 24fps and 1/50 shutter speed, 24fps and 1/100. Also tried 60fps at 1/60, 1/125 and 1/250. All were choppy.
Upshot is, it doesn't seem to matter what frame rate I use, what shutter speed I choose (even at the rule of fps=1/double for shutter speed) or how slowly I pan.
I must be doing something very wrong somewhere!?

Forgot to mention; I also tried 24fps with a slower shutter speed of 1/30s, which was the slowest the camera would allow for that frame rate. Did it make a difference? Hell no! It was just as choppy as 24fps at 1/50 and 1/100!
Most peculiar!
