FAQ
Does audio speed change too?
Yes, audio changes with speed. Faster playback generally means higher pitch.
What's the slowest speed?
0.25x (quarter speed) for dramatic slow-motion effects.
What's the fastest speed?
3x. Higher speeds may cause audio distortion depending on the source.
Can I keep the original audio pitch?
Pitch-preserved speed change requires more complex processing and isn't included here.
Will slow-motion look smooth?
Results depend on the original frame rate. 60fps footage looks smoother in slow motion than 30fps.
