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.
For me, x10 is often too slow, since I make speedpaints and I end up almost having to loop music tracks in order to fill the video.
I second that. I make tutorial videos, and sometimes I want to speed a step up just a little. 2x is often too fast. Completely custom values would be ideal, but even if there were settings for 1.25x and 1.5x, it would really be an improvement.
Hi guys! First of all love Filmora I am using it for every video I make and I am very satisfied with the software. But a little suggestion regarding this particular feature - can we get more options to slow down/fast up our videos (and sounds), preferably to add our own values, like 0.75, 0.85, sometimes videos need just a tad of adjustment rather than doubling the value and having values open to add custom numbers would be much appreciated!
hello im new in filmora my version in filmora is 7.8.0 and i want my video goes faster but the problem is that i cant find it i click the video and edit it..its only motion and audio..(help?) i really need it for our projects.. . ... THANKs
how do you speed up just one part within a vid clip not the entire clip?
