Speed Ramps- Blog Investigation & Work Log 12/5
In my film, I am planning on adding speed ramps in a few scenes in the montage. Speed ramping is the process of gradually adjusting the speed of a video clip over time. Mainly to slow a clip down to slow motion and then to speed it up again. Speed ramping, sometimes known as The Matrix effect, allows you to easily shift between rapid and slow motion. You can even customize the rate of transition between the two speeds, choosing between a smooth and gradual slowdown or a swift and instantaneous flip.
Frame Rate: If you want to produce a good-looking speed ramp, make sure your movie was taken at a high frame rate. You don't have to rent a high-speed camera like the Phantom Flex, but you should capture your photographs at a faster frame rate than your baseline (most likely 24 fps). Most cameras can record at 60 frames per second, 120 frames per second, or even 240 frames per second. The faster you can slow down your footage in post-production, the higher the frame rate. For me, the camera I used only went up to 60FPS, so in premiere pro, I could only change the speed down to around 40% before it became choppy.
Lighting: The faster your frame rate, the less light your sensor can capture, resulting in poorer photographs. As a result, make sure to supply sufficient illumination to compensate for the loss of light.
Camera Movement: When speed ramping, smooth and stable film yields the greatest results. Speed-ramping handheld film is still possible, but the problems of shaky, jittery imagery will be amplified by the change in speed. If you don't have stable hands, it's better to use a steadicam, stabilizer, or tripod to make your footage smooth. You can also stabilize your film in post-production prior to speed ramping.
