Below is the Slow Motion Frame Conversion Chart referenced in the article How To Create Extreme Slow Motion Using Apple Motion.
The below chart has two important purposes.
- Determining the correct speed to set your footage to try to achieve a particular Frames Per Second “look”.
- OR, determining your final simulated frame rate after setting your custom clip speed.
Use the Chart below like a multiplication table to understand and choose your frame rate as you create your slow motion video. If you were shooting at 60FPS and wanted to do some tests of 6000 FPS you could see from the chart that you will have to reduce the original video speed to 2.5%.
- The top row of numbers in the grey represent the frame rate that your camera is shooting on.
- The row of numbers in the grey boxes down the side represent common speeds you may choose to slow your footage down to in Apple Motion.
- The numbers in the blue boxes represent the final frame rate simulated once in FCP and after being conformed to 24FPS.
Please Click the chart for a pinter friendly/ high res. version.
The chart above is only applicable assuming you are conforming your final video to 24p ( or shooting 24p to begin with).
Numbers with Asterisks ( *) are rounded to the nearest whole number.
For best results, shoot in 60 FPS at shutter speeds of 1/1,000 or higher.
