Slow, Fast, Reverse, and Freeze Motion in Sony Vegas Pro

Speed ramping is a snap in Sony Vegas Pro
Using reverse creates a new subclip in the Project Media pool and also makes this subclip the Active Take on the Timeline. The original media will be Take 2 and also remain in the Project Media, too.

Velocity Envelope
What if you want to change the playback speed of a clip over time? Vegas fully supports this effect, often called 'speed ramping.' You apply this to an individual video clip as an event-based effect using a breakpoint style envelope. Right-click the Event and choose Insert/Remove Envelope > Velocity from the pop-up. Using the Velocity envelope opens up a wide-range of interesting video effects.

This places a green line that runs through the video. The line defaults to 100% velocity or the normal playback speed. Double-click on the line to add a point. Move the segment up to play faster (up to 300%) or down to 0% (a freeze frame). With the Velocity envelope controlling the playback rate you can move below 0% to negative values (up to -100%) which plays from slow to normal motion in reverse!



If you right-click a Velocity Envelope point, the pop-up menu offers a bevy of tools and shortcuts including the ability to change the fade shapes from point to point. Experiment with the fade shapes to achieve the precise look you want. To input a specific value instead of moving the point, use the 'Set to' option.

Freeze Frame
As mentioned earlier, you can set a video's Velocity Envelope to 0% to create a freeze frame. There is another method, too.

Park the cursor where you want the freeze frame and split off the single frame. Right-click this single frame and choose Create subclip from the pop-up menu. Right-click the newly created subclip and choose Switches > Loop and turn that off. There should be no checkmark next to the word 'Loop.' Now drag the subclip out for as long as you need the still frame to be.

For an alternative way to create and use freeze frames, see my other DMN article "Taking a Snapshot Inside Sony Vegas" at:

There you have it, several ways to control the speed your videos playback using Sony Vegas Pro. I'm sure you will find plenty of creative ways to apply this effect. I'll be watching.

A special shout out to Artbeats (www.artbeats.com) for their kind permission to use clips from their Environmental Impact collection for this tutorial.
