How do I make a video slow motion with AI?

Upload your clip, choose how much to slow it down (2x, 4x, 6x, or 8x), and the AI generates new in-between frames with interpolation to produce smooth slow motion you can download.

Is the AI slow motion generator free?

Generation requires credits from a paid plan. Each slow-motion render uses credits based on the clip length and slow-mo factor. Paid plans include more credits.

Do I need a high frame rate camera?

No. That is the advantage of AI slow motion. It generates the missing frames for you, so even standard 24 or 30fps footage becomes smooth slow motion without special equipment.

You can slow footage up to 8x. Higher factors generate more frames, which is ideal for dramatic action, splashes, and detail shots.

Does it add motion blur?

No. AI interpolation keeps each generated frame sharp, so your slowed footage looks like it was filmed at a high frame rate rather than blurred.

Can I slow down AI-generated videos?

Yes. It works great on AI-generated clips, which often output at lower frame rates. Slowing them with interpolation gives a smoother, more cinematic result.

Can I use the slow-motion videos commercially?

Yes. Everything you create on Melies is yours to use commercially, with no watermark and no attribution required.

AI Slow Motion Video

Turn any clip into buttery-smooth slow motion. Instead of just stretching frames, Melies uses AI frame interpolation to generate new in-between frames, so even footage shot at 30fps becomes fluid, cinematic slow-mo.

Original frames + AI-generated in-between frames = fluid slow motion

How to make a slow motion video with AI

Upload your clip

Drop any video you want to slow down. It works on phone footage, AI-generated clips, and standard frame rates, no special camera needed.

Choose slow-motion speed

Pick 2x, 4x, or 8x slower. The AI calculates how many new frames to generate for smooth, natural motion.

Download your slow-mo

AI interpolation fills in the in-between frames and renders fluid slow motion you can download and share.

What makes this AI slow motion different

Normal slow motion just duplicates or stretches frames, which looks choppy. Melies generates brand-new frames with AI so motion stays smooth even at extreme speeds.

AI Frame Interpolation

The AI generates new in-between frames instead of duplicating existing ones, producing fluid motion with no stutter or judder.

Smooth At Any Speed

Slow footage 2x, 4x, or 8x and keep movement buttery smooth. Even fast action stays clear and natural-looking.

No Blur Or Ghosting

Unlike motion-blur tricks, AI interpolation keeps each frame sharp, so slowed footage looks like it was shot at high frame rate.

Works On Any Footage

Turn standard 24 or 30fps video into slow motion. No high-speed camera or special equipment required.

AI-Video Friendly

Perfect for smoothing and slowing AI-generated clips that output at lower frame rates, giving them a polished, cinematic feel.

Connected Workflow

Slow down, extend, and upscale clips in the same project. Build the whole shot without leaving Melies.

Slow-motion speeds

Choose how dramatic the slow motion should be. The AI generates the right number of frames for each.

Subtle slow-mo. Great for adding weight and drama to everyday motion.

Classic cinematic slow motion for highlights, reveals, and emotion.

Strong slow-mo for action beats and product hero shots.

Extreme slow motion for splashes, impacts, and dramatic detail.
