Frequently asked questions
How do I make a slow-motion video?
Pick 0.5× for half speed or 0.25× for very slow. Videos shot at 60 fps look smoothest in slow motion.
Will the voices sound strange?
No. The pitch stays natural; only the speed changes. At very high speeds speech is hard to follow, so you may prefer Remove sound.
How do I make a timelapse?
Pick 3× or 4×. For an even faster timelapse, run the result through again.
Does it change the file size?
Faster videos are shorter, so the file is usually smaller. Slow motion makes the video longer and bigger.
