FR peace of mind

I hope I don't bother anyone with this question but even after all I have read and all I have thought about it I'm still confuse about this subject and for once wish to have some peace of mind if that's possible at all...



footage shot at 24fps will look like film and footage shot at 30fps will look like video....

will that be the case if they both are using same settings?
will 30fps make the footage look like video or is it just the cadence?
if its just cadence...will this 2 cadences look that different?
doesn't 24fps gets converted to 30fps when played by DVD player anyways?
will still keep the film look with DVD player added pulldown?

I wish to understand this part for once so I can make a more secure decision when choosing what FR to shoot with.

I don't mind doing 24fps but we know we loose frames for any slow motion later....


thanks a lot and have a wonderful day..

DVD's and players can in fact do 24fps, and this has a couple advantages.

1. more available space on the DVD
2. film look

Don't be too prepared for a revolutionary new look when going to 24 though, as many other factors play in to the "film" look. Lighting and shallow depth of field, for example, help alot to acheiving a more professional film look...not to say that these are the only factors though.
 
No 24fps does not get converted to 30. What happens is that the frames get duplicated to acomodate and keep the 24fps action happening.

Like say for example (let me use an even number) if you record at 30fps and you broadcast at what's called "over 60" then each frame would get duplicated to fill the empty spaces. So your eyes would still see the action at 30fps when in fact you are watching 60 frames pass by, but each one is being duplicated to fool your eye and keep the 24fps action.

Do you understand?

so if you record at 24fps and are playing back at 29.97 (or rounded to 30) then the ratio of frame duplication is different. Maybe like 1 and a1/2 or so But it's still playing the action at 24fps and streaming it at 30 duplicating what ever frames it needs to in order to fill in the spaces and fool the eye.

Do you get it?

no you guys

24 never gets converted to 30


24fps either gets pulled down into 60i or 60p, with 2-3 pulldown
 
thanks for making my confusion more confused..

1-so, 24fps doesn't make the picture look like film but has the same cadence as film...right?
2- so, 24fps with pulldown still looks more the cadence of film than 30fps?


I know about the pulldowns and how it all works...and I know the fisical difference between 24p,30p,60i......what I'm trying to understand is if the frame rate affects the look of a picture besides giving more or less frames to the video....and how...

thanks to all for feed back..

1. 24fps does make the picture look like film. I would say that 24fps has the same cadence as film when shot in "native"

2. yes

adding or subracting frames in most cases does not change the look as long as it accomodates correctly.
it depends on the editing and / or plug-ins that people use to convert frame rates and stuff.

the timeline, method, or settings that you use to edit the footage can make a difference on the look of the final product.
 
there are many framerates


24p
30p
60i

ect


60i looks alot more like 60p, but with half the spatial resolution...

60i means 60 interlaced fields per second...the camera captured one interlaced field every 60th of a second, so the cadence feels like 60p, which feels very lifelike and video-ish, if I could put it that way


24p of course IS the cadence of film, so the motion is more filmic.


30p has 6 more frames per second than 24p, and the change is noticeable

when 24p footage, or 30p, is pulled down into 60, the motion is, for all intents and purposes, exactly the same.
 
Yes, I just shot a job at 30P at the client's request and am now editing it. It looks kind of like a cross between 24p and 60i. It looks more "live" than 24p but nicer than 60i. Not a bad compromise if you are positive you are never going out to film.
