How to shoot Sonya72 upgrade depends on whether it is upgraded or not.

Canon 5D3 can achieve 60 beats of 720p! Determine your target frame rate first. For example, if you are a 24P project, first set up a 24P sequence, and then drag the 60P material directly to the time, and adjust the speed and duration with attributes. For AE, you can use Time Warp, which is advanced and can be stretched infinitely. You can stretch the 60fps material to 1000fps by inserting frames, which is also very smooth.
