How to make Fast motion (Time Lapse) in your video editor with Kdenlive
- 7 years ago
want to create fast-motion for a section of a clip on the timeline.
The effect `Motion | speed' looks like it should do what I want, but the description says "Process audio using a SoX effect" (???), and on the Effect Stack there are zero controls to govern how much faster (or slower) it should go.
On `Project | Clip Properties | Advanced' there is a `Force frame rate' control, but that applies only to the entire clip. I cannot find a similar dialog for a portion of a clip.
Is there a means of effecting fast-motion (or slow-motion), and how?
Speed up or slow down a video clip
‘Motion’ is one of the many keyframable effects. Applying ‘motion’ to a clip allows you to to speed it up or slow it down. If you want slow motion on a clip you decrease the speed value from 100% And this is the end result: simulated slow motion.
To speed up the clip just set a value greater than 100. And there it is… a 4×4 faster than a jet. The stroboscope defines the the number of frames skipped on playback. If I set the value to 20, the effect will be applied every 20 frames but will extend the clip duration by 20 times, although the frame skipping will shorten it. Simplifying… this effect is an illusion of movement created by the overlap of the images in a logical sequence as demonstrated by the image on the ‘clip monitor’.
