Built around one job: a flawless carousel.

Stop trimming clips by hand and guessing how your cover will crop. SliceReel does the tedious part so you can just post.

Smart auto-split
Split one video into carousel-ready clips.

Drop in a 60–90 second video and SliceReel cuts it into clean, equal clips. Choose the number of clips or the seconds per clip — it keeps you inside Instagram's limits automatically (up to 20 items, 3–60 seconds each), so the carousel reads as one continuous video.

First-frame cover
Design a cover on the first frame.

Add a text band or import your own cover photo, placed on clip 01's first frame — the exact frame Instagram uses as your carousel thumbnail. Bring a vertical cover to a landscape video and SliceReel keeps its shape, filling the sides with black. No Canva round-trip.

Live grid preview
Know exactly how your grid will crop.

Instagram crops your profile grid to 3:4 — so a beautiful cover can lose its top and bottom the moment you post. SliceReel shows the precise crop and a safe-zone overlay while you design, so your cover always lands. This is the part you can't do anywhere else.

Ordered export
Export every clip in the right order.

Clips save to a dated album named 01…NN so they upload in sequence — no more shuffling files. Every clip keeps your video's native aspect ratio, so all slides match, and you can mute the audio on export with a single toggle.
