Where can I find highspeed test footage?

[David Ghast]

Ive been looking for native 120fps sample footage that has not been slowed down or converted to another framerate but have had no luck with google, does anyone know where i can find this?

RED footage at 120fps has been posted here before. Look in the footage threads or search the threads. You can also look on vimeo or redrelay.net.

Checked vimeo, but all 120fps had been slowed down and/or converted to 24/30fps without any warning. Actually I cant seem to find any native 120fps on here either. Can you point me to a clip?

edit: also scoured redrelay, found three 120fps clips, but they had all been slowed down to 24fps. No luck yet...

Any shot taken on the RED camera at any frame rate will play back at a "time base". 23.98, 24, 29.97 or 30 fps. Most displays couldn't playback 120fps at 120fps anyway.

Come again? How are you supposed to edit and timewarp highspeed footage if what your suggesting, that the red does framerate conversion incamera, is true? That would mean that the red cant shoot at 120fps, it can just sample at 120 and shoot at, i dont know, 60 max? If thats true, thats rather sad.

No, it samples at 120 and records them to a 25fps file. You can run the file at 120fps if you like, but all 120 frames per second are in the 25fps file.

 

[David Ghast]

You mean that in a given second, the 25fps im seeing actual contains 95 frames that are present but hidden?

nevermind, i guess that wouldnt be true considering all the footage i have is slowed down, so i guess im seeing all the frames. God damn this is becoming confusing.

120 fps playback is not a supported display standard by anything. The camera shoots at up to 120 fps, if you play that back at 24fps you get slow motion. If you want it to play back with less slow mo, you would be discarding frames. It's exactly the same as shooting 120fps on film.

Not sure what you are getting at here. Hope that helps.

Look, no frame rate conversions. You shoot 120fps. The only reason 120fps gives you slow motion is that you then play it back at 24fps. You are stretching time.

So you now want to "remap" time. Speed it up. Speed it up as fast as you like. Go any where in between. Welcome to time remapping.

You're confusing recording rate and playback rate.

Normally, you record and playback at 24 in the cinema.

If you record at 48, and playback at 24, you will find it takes twice as long to watch your footage. This is how slow motion works.

So, if you record 120fps, one second of shooting creates 120 frames. When you play back those 120 frames at 24fps, it will take 5 seconds to watch, because you can only watch 24 frames a second on your playback device.

Not sure where you got sampling at 120 and shooting at 60.
