Slomi: Slow Motion Video Maker

Make a slow motion video from any clip, or speed it up. Slomi is a slow mo editor with a speed slider from 0.25× to 4×, speed ramps, reverse, freeze frames and timelapse. A plain speed change copies the picture without re-compressing it, so quality stays the same.

▸ SPEED SLIDER, 0.25× TO 4×
• Set the exact speed, or use quick picks: 0.25×, 0.5×, 1.5×, 2×, 4×
• Change the speed of one part only; the rest stays normal
• Fit the clip to exactly 15, 30 or 60 seconds
• Trim the video first; trimming is lossless

▸ SMOOTH SLOW MOTION VIDEO
• Frame blending so slow motion doesn't stutter
• Clips shot at a high frame rate are detected for true slow motion
• Motion interpolation (Beta) builds in-between frames; pick Motion or Blend for each slow part
• Motion blur, LED flicker removal, and stabilize before slowing
• Record at a high frame rate on phones that support it (no sound)

▸ SPEED RAMP
• Presets: Hero, Velocity, Bullet time, Slow → fast, Fast → slow, Pulse
• Draw your own speed curve with easing and share it as a link
• Speed synced to the beat of a song; "Hit the drop" puts the slowest point on the drop
• Hold to slow: press on the preview where it should slow down
• "Find every moment" gives each action peak its own speed ramp
• Zoom punch, shake or pulse on impact; the zoom can follow a face or the movement
• Whoosh sound as the slow part starts

▸ REVERSE, BOOMERANG, FREEZE, LOOP
• Reverse a clip, or rewind it with a VHS look
• Boomerang around the moment
• Freeze frame (Plain, Snapshot, Polaroid) and save that frame as a photo
• "Freeze at the peak" picks the sharpest frame at the action peak
• Loop a clip; "Seamless loop" finds the end frame that best matches the first
• Stutter, motion trail, and a speed or clock label on the video

▸ FAST MOTION AND TIMELAPSE
• Timelapse from 8× to 64×, or hyperlapse that removes walking shake
• Smart fast-forward speeds up the waiting and keeps the action at 1×
• "Keep talking at 1×" leaves the parts where someone speaks alone
• Frame rate: smooth 60 fps, cinematic 24 fps, stop-motion, or fix a variable frame rate

▸ SOUND THAT FITS
• Keep the sound at natural pitch, or choose deep slow-mo, tape or off
• "Suggest sound for the slow part" listens for speech, music or noise
• Replace the sound with a song from your phone

▸ MORE IN THIS SLOW MO EDITOR
• Save as GIF or HD GIF (720p)
• Change the speed of several videos at once
• Compare the original and the slow version
• Trending recipes, and a sample clip to try first

▸ FAQ
Will my slow motion video lose quality? A plain speed change keeps the original picture; smoothing and effects re-encode it.
Does this slow mo editor add a watermark? No.
Very slow motion looks choppy? Turn on frame blending, or film at a higher frame rate.

▸ EXPORT FORMAT
Reads MP4, MOV, 3GP, MKV and WebM. Saves MP4, GIF, and JPEG for freeze photos.
