For macOS on Apple silicon

Slow motion,
only where it matters.

Mark the moment. Slowframes generates the frames that were never filmed, right on your Mac, and leaves the rest of the clip exactly as it was.

Slow down a moment, not the whole clip

Set an in and out point, pick a speed, and shape the ramp with ease handles. Everything outside the region plays at normal speed.

Slowframes uses RIFE frame interpolation to create the in-between frames, so slowed footage moves smoothly instead of stuttering.

Built on Apple's MLX and the media engine in Apple silicon. Your footage is never uploaded anywhere.

Preview timing in real time while you edit. Export decodes and encodes in a single pass, so untouched footage loses nothing.

Drop in a stack of clips and slow them all down end to end. Same engine, no timeline needed.

Opens H.264, HEVC and ProRes from your files or Photos. Exports H.264, HEVC or ProRes, hardware accelerated.

Slowframes is almost ready. It will be free to download.

Requires macOS 14 or later on a Mac with Apple silicon.
