SLOW MOTION TRANSITION QUESTION

[Tim Morris]

I HAVE A QUESTION REGARDING SHOOTING A SLOW MOTION SCENE. I UNDERSTAND THAT THE HIGHER THE FRAME RATE...... THE SLOWER THE CLIP WILL BE.
FOR EXAMPLE, IF YOU SHOOT A 300FPS IN 2K...THE SHOT WILL BE VERY SLOW. HOW DO YOU SHOOT A CLIP THAT STARTS OUT IN 24 FPS AND TRANSITIONS TO 300 FPS. IS THIS TYPICALLY DONE IN POST.

Look into the camera manual for 'speed ramp'

Speed Ramping is a special recording mode that let's you set up to 4 different frame rates and transition from one to the other in a given duration (A->B->C->D)

You can choose what to do depending on how you want to work. You could shoot the whole thing overcranked and then drop frames in post to do your speed ramp, or you can do an in-camera ramp.

An in-camera ramp will cause an exposure shift which you'll have to figure out how to compensate for, but on the plus side you could retain "normal" motion blur at the lower end of your frame rate ramp (depending on how you deal with shutter angle / exposure time).

Shooting everything overcranked will keep a continual exposure but will also give you a "narrow shutter" motion blur look on everything no matter what your final framerate is in your edited piece. You can add motion blur in post, to a degree.

Also, please refrain from typing in all caps in this forum. It's extremely obnoxious.
