1/16th Review Recommendations for Computer Based systems.


1) A simple calculation can determine what the playback considerations should be.

1/16 = 0.0625 * 5 (seconds) = 0.3125

Now take the framerate you shoot with your camera:

29.97 * 0.3125 = 9.37 frames (round down to 9)

59.94 * 0.3125 = 18.73 frames (round up to 19)

***Thanks to Jeremy Olson for providing the formula!


2) So now you have the number of frames required to step through a review at 1/16th speed on a computer viewing program, like QuickTime.

We have tested the Mac QuickTime viewing accuracy by loading the same footage into QuickTime and Premiere Pro editing software and matched it for frame by frame accuracy following the above formula. It matched up perfectly.

Whatever review software you use you need to know how it handles video playback PER FRAME. This is important!


Some software programs will require double steps to cover one frame. Some, like the Mac QuickTime program (and I'm assuming Windows as well) covers one frame per step.

VERY IMPORTANT TO KNOW WHAT FRAMERATE YOUR CAMERA IS SHOOTING!!!! YOU WILL GET YOURSELF IN TROUBLE IF YOU DO NOT UNDERSTAND THAT! ALL VIDEOGRAPHERS MUST UNDERSTAND THEIR EQUIPMENT TO APPLY THESE CALCULATIONS AND PROCEDURES!!!!


Video shot at 60 frames would require 19 frame clicks to cover the 1/16 review process.

Video shot at 30 frames would require 9 frame clicks to cover the 1/16 review process.

To recap the process:

-Shoot to an SD card.

-Take the card to your review station computer.

-Activate QuickTime (or the program of your choice keeping in mind what I mentioned above) video review program.

-Within the movie review program, select the video movie file.

-Position the video playhead in the movie review timeline where the judge determines it needs to be to start the 5 second (1/16th) review process.

-Click 19 advancements (most likely using the Right Arrow key on the keyboard) for 60 frames a second video OR 9 advancements for 30 frames a second video.
