Been asked many times before:
Alright! So the speed filter! Basically this can be used for speed up/slow down moments. Heres what it does. So it gets the previous “sections” speed and then the speed of the section currently being edited it and creates a tween. The only way to do this right now is to make a bunch of frames in-between the two frames and set them to different speeds but that can appear choppy and weird looking.
It can be used for videos only.
Really just one property… Speed or time. Similar to th…
At the moment, I’m slicing up a clip, adjusting the playback speed for each the clip repeating that until I go from 1.00x to 3.00x (OK, it’s motorcycles on meth, but I like it). Each step is initially the same number of frames. The change isn’t linear because each speeded up clip is shorter than the one before it. I’m too lazy to do the math to get the number of speeded up frames come out to the original duration (30 frames at 1.5x becomes 15 frames duration - the clip has to be doubled to equal…
Is there a way to fade-in with the playback speed. What I mean is to smoothly change the playback speed let say from 4x to 1x.
So for instance I am connecting a video where the previous cut is playing at 4x faster… and I would like to go down with this speed smoothly (from 4x) to the normal playback (1x).
How can I get this?
I would like to gradually speed up a small section of video that is located in the middle of the clip. Can someone point me in the right direction?
It’s a reasonable request, but it is unlikely variable playback speed will be implemented in Shotcut due to the complexity of the problem. Shotcut always needs to know the exact length of each clip. It is difficult to calculate the length of a clip if the speed changes multiple times throughout.
