Izzy Video 108 – The 300 Effect aka Variable Speed Changes
Thanks to Amber Heckler from Norfolk, VA for requesting this week’s topic. She wrote me at izzy (at) izzyvideo (dot) com and asked:
I was wondering if you could do a tutorial on how to achieve the “300 Effect” in post production. To me the “300 Effect” is when a piece of video seems to speed up, and then slow down; mainly seen in fight sequences.
Izzy Video 108 answers this question.
Some of the topics I cover in this episode are:
- What is a variable speed change
- Time-Remapping
- Video Frame Rates
- Smoothing Keyframes
This is one of those techniques that can be a lot of fun. My children certainly enjoyed making this video!

Looking forward to using this technique. Currently I’ve discovered the SmoothCam optioin thanks to your tutorials. Really impressive results even with a handheld camera.

I am wondering what filters were used on this… It’s incredible but I can’t quite get my shot to look like this.

Hi Scott,
Inside of Apple’s Color, I created my own look by mixing several different things. It’s too hard to explain right here, but I’ll happily do a screencast on it for the members.
Thanks for watching!
All the best,
Izzy
