Timelapse/Slow Motion effects, also known as Speed Up/Slow Down effects in video production, which make the video clips play faster or slower than original speed.

Double click in the section of video you want to change the speed on. It will bring up the edit page. on the page if you look down at the 6th line down its says speed. You can move the slider from normal (Center position) to the left and slow down to .1X or slide it all the way to the right and go as high as 10X. Its a complets slider and as you move it, it shows the speed. Its EASY to use and very useful. PS I have used quite a few video editors and FIlmora is one of the easiest ans efficient i have used.

There is no function for speeding up or slowing down your video clip on Filmora. I have been messing with this for an hour and the only advanced feature for editing the clip are "Mask" and "Affect". Both useless. There is a function to adjust sound but no function to adjust speed.

There is no window that comes up on clicking on the video that allows you to adjust the speed. Just other visual affects. I tried a variety of way to get it to open and it doesn't work.

I'm really angry about not being able to speed up my video clips...

I am fairly new to filmora and I'm loving it so far. Only thing is I would like to be able to customize the speed of clips. I would highly recommend enabling a custom preference to the speed, speeding up especially. Going from x1 to x2 is far too great of a gap. See what you guys can do.

I haven't really tried this myself, but would it be possible to get, say, 1.25x in two steps? First make a fast 5x case, then make a (slow) 0.25x version of the fast 5x version?

I agree 100%.. doing a 2 hour timelapse of a sunset will be like 5min on 10x.. i need it to be like 30 seconds..

I too am new with Filmora. Man was I confused at first (don't have instructions), it was trial and error. My last video editing software was Windows dvd maker; it is so basic even a chimpanzee with ADD can learn it. When I discovered Filmora, it was a big step up to editing home videos. Now I use it to edit wedding and party videos from other people. I won't lie, it took me some three weeks to find out how to use Filmora, but it is worth it. Yet, I remain perplexed with some of the features and hesitate experimenting too greatly for fear of damaging the hours upon hours and days and weeks of edited videos. If win the Lotto I'll purchase a better version of Filmora, and a newer high-quality videocam. My ancient Panasonic PV GS320 (12 years and still running) remains working flawlessly but the quality of videos clearly shows its age.
