24FPS vs 30FPS Motion Test

This video is created with the motive of checking the flow difference between 24FPS and 30FPS videos.

As shown in the video; flow difference between pure 24p feed and Motion 2 60p feed can easily be noticed; unlike many other claims.

Movie: Tron Legacy Bluray 1080p

EDIT: Actual FPS of the original video is 60p (60FPS). Unfortunately I learned after uploading the video, due to Youtube restrictions any video is limited to play at 30FPS. So the 60FPS scenes are played as 30FPS and the video compares 24p and 30p.

@salam14111 They only ever record higher than 24p in cinema if they know that for a specific scene they will be doing time re-mapping.

@nexus1g Some colegues have just been at one of the big media shows at RIA amsterdam and yeah apparently the manufacturers of flat screen are big on the idea of 4k(ish) screens so HD is now old hat and we must prepair for more resolution.

The 4k spec seems a bit flexible I think most manufacturers were talking about 3800x(somthing that makes 16:9)will ask if they remember better

I did see a 12megapixal screen from hitachi or panasonic(iirc) at IBC about 3 years ago that was awsome.

@stu0things0and0stuff We'll see how it looks with the Hobbit in December. I don't remember the other films off hand that are doing 48 FPS. I honestly didn't know they still used celluloid at all to worry about it. I want to visit something you said earlier that I meant to address but didn't: They're coming out with 4k+ vertical resolution? Or did you mean something different?

[stu0things0and0stuff]

@nexus1g ahh , humm , I kind of like motion to blur, like when you look out a train window and its all a blur :-)

Post costs could go up double data and all that. Lucky their not intending to do that with actual film (or are they?) as I know that (afaik) 70mm film dosn't use cogs to move the film it actualy blows compressed air onto the sprocket holes to move it as the teath on the cogs tended to just rip it appart at that speed (70mm frame v.big lots of strain starting and stopping)

[nexus1g]

@stu0things0and0stuff The goal of 48 FPS (as is my understanding) is to make fast-paced action more "visible" (e.g. less blurry). They're doing the Hobbit and a couple of other films this year at 48 FPS. Peter Jackson stated that 3-D at 48 FPS reduces eye strain significantly. But I have to figure that increasing to 48 FPS greatly increases post-production time/cost too.

@nexus1g is the 48 fps thing so they can do stereoscopic on the cheep with one projector I wonder ? (have a poloriser on the projector and change it each frame)

[stu0things0and0stuff]

@nexus1g havn't been keeping up with the times , didn't know they are trying to put it up to 48fps , although I dobut they will now theirs a load of 4k(ish) displays on the way they probably need the bandwhidth for the extra picture data(probably still a year or 3 before their common).

Interestingly the chaplin films that we see looking rough are normaly the result of a bad 16mm print(copy) as he was obsesed with lovely looking 35mm although I think his silent movies are 18fps

[nexus1g]

@stu0things0and0stuff I didn't know about the change from 18 FPS to 24 FPS. That explains the "feel" of silent movies like the Thief of Bagdad or Chaplin classics. I knew about the projectors actually projecting the same frame twice because of the recent talk of upping the standard to 48 FPS. All-in-all good info. Thanks!

[stu0things0and0stuff]

@nexus1g also I would just like to second your use of more correct terminology ;-)

the following terms, speed (recording and showing fps match)

over kranked (slow mo) shooting fps exceeds playback fps

under kranked (fast motion / timelapse) shooting fps is less than playback fps

[stu0things0and0stuff]

@nexus1g true but the whole percistance of vission thing is used a lot , film projectors project double frame rate (flash the same frame twice) i.e. 18fps video projects 36 flashes/s , we only went from 18fps to 24fps motion picture to support sound ;-).

As you say the choppyness people get with lower frame rates is due to the shutter speeds mostly. (or they are panning too fast)
