“Slow motion is fascinating because mundane objects take on a completely different aspect when you observe them outside the bounds of normal perception,”
-Filmmaker Lawson Deming
Do you want to include a really neat slow motion effect/technique that makes your video clips stand out more? Speed Ramping is a popular premiere pro effect tool that initially allows video clips to quickly shift from slow to fast over a period of time, vice versa.
One example where this effect was implemented was in the movie : “ 300” As King Leonidas bursts out of the battle formation, the movie slows down before and during every attack he does. This allows the viewer to focus on the most significant parts of the video and helps highlight the critical moments. The main purpose of speed ramping is to allow the viewer to be more observant to a specific part of the film giving us a wider understanding of the directors main intentions.
Speed Ramp a Clip
Step 1: Expand your video track in order to be able to see a white line in the video clip.
Step 2 : Right-click the top left ‘FX’ square that opens a drop down menu and click over ‘Time Remapping’ → ‘Speed’
Step 3 : Hold the ‘control’ key and click on the white line where you want to start your speed ramping. This will bring a speed marker to the clip.
Step 4 : Click, hold and drag the white line after your speed marker vertically to adjust and set the speed for your desired ramp. (Up increased speed, Down decreased speed)
Step 5 : To create the ramp click & drag the second half of the marker to the right. (Depending on how far you drag the marker will control the speed of your speed change.)
Step 6 : To smoothen out the ramp, select on one of the markers to see a small square point in the middle of the markers. Since our ramp began on the right, drag the point towards the right to form an ‘S’ shape with the white line.
Step 7 : Do the same steps to where you want to end your slow motion effect to your clip.
Heads up..
Using slow motion with a low frame rate clip will make the clip look choppy and far less like slow motion. Therefore the solution to this problem is to add ‘optical flow’ to your clip.
Step 8 : Right click on the clip, select ‘Time interpolation’ → ‘optical flow ‘
Step 9 : Head over to sequence on the top left bar of the screen and select ‘Render selection’
Quick Warning…
It should be mentioned that optical flow can be a bit difficult to compute on your computer’s hardware. Choosing ‘render selection’ will also allow you to smoothly playback the clip.
