Frequently asked questions
How do I make a video slow motion?
Choose 0.5× or 0.25× and the video plays at half or a quarter of its speed. For smooth slow motion, the original should be filmed at a high frame rate.
Is the pitch of the sound kept?
Yes. The sound is stretched or squeezed without changing its pitch, so voices do not turn into chipmunks or get deeper.
Can I speed up a video and keep the sound?
Yes. Choose 1.25×, 1.5×, 2×, 3× or 4×. The video gets shorter and the sound speeds up with it.
