Best shutter speed for filmic look?
- Thread starter someday
- Start date
Hi guys,
Nice to see discussion on shutter speeds re pans and tilts.
Sometimes if I'm doing a slow pan around... say a large space with people, I have to nearly stop during the pan on different groups of people so that they are actually visible during the pan, otherwise they would be too blurred and with faster shutter there can be too much strobing.... that's using a nice pro tripod too.
On static or nearly static subjects, I often increase my recording frame rate to 60fps with playback set at 24fps - with a high shutter speed, then do my pans and tilts / movements which achieves a very smooth look and takes any flaws out of the movements when using zoomed in.... You may have to do your movements very fast to achieve the normal length of time required for the movement but it looks really smooth played back.

I have the same qestion.
I know guys that shoot snow boarding with film cameras that never have strobbing/scattering???
I also have a friend that shot film back in the day and he has never seen the sort of strobbing/scattering we get with our HVXs?
Maybe its just me but I dont get it. We are shooting a new doc that needs to be in HD, but the 24P thing is way to strobby. Even with the shutter at 24 its still strobbing a little?
Any advise???

shutter speed= (shutter angle/360) / frame rate
so
1/43 = (200/360) / 24
1/54 = (200/360) / 30
so
1/43 = (200/360) / 24
1/54 = (200/360) / 30

Correct me if I'm wrong, but if you're shooting snowboarders in the snow you're following the subject against a primarily white background so you wouldn't notice much strobing. The strobing issue doesn't seem to be much different from a standard film camera to me. Granted it's shocking going from 60 field video where there's virtually NO strobing to 24P.
Using a slower shutter speed helps, I guess, but the motion blur always seems to look a bit more digital with 24P video than film so maybe thats the difference, I dunno...

I appologise for not posting the footage. This seems to happen most of the time when I say I will post something. Doing replies is fast and takes me little time, but having to digitize, compress and finding a place to host footage is a pain in the *&s.
If you guys could find me a place to host this that doesn't require a whole day for registering and uploading, that would help...

While I haven't done much in the way of full-blown production yet on my HVX, I have found that the strobing effect is much less noticeable once footage has been put on a DVD and viewed on a TV monitor. I have both a 42" plasma and an HD front projector, and the strobing seems much more like film when the footage is viewed on them. Also it seems that strobing is less noticeable on my MXO equipped 23" ACD than in the main monitor's FCP windows.
My theory is that the effect is somehow exacerbated by the computer's handling of the footage, the (non MXO or equivalent) LCD monitor's or both. In any case, it's severity diminishes a to film-like state once it goes from the NLE environment to TV. As others have reported, evidently this is equally true in film-out projection. I'm still looking forward to seeing that for the first time.
I should add that I notice mild to severe strobing in feature films all the time now, whether in a theatre on on a TV screen, now that my radar is all up about it.
