Extend any video. Fit every screen.
aivideoextend continues your footage with natural AI frames and reframes it into 9:16, 1:1, and 16:9 — your subject stays centered in all of them.
See a 6-second clip become a 30-second cut — made with aivideoextend
A good clip should not die at the edge of the frame. aivideoextend extends your footage and reframes it for every platform — thousands of generated frames, each one checked, so the motion stays believable and your subject never drifts out of shot.
Built for the frames that get cut
Most tools crop and hope. aivideoextend is engineered for the part that keeps your subject in shot and your motion believable, on every screen.
01
Extend, don't loop
New footage that continues the motion, light, and grain of your clip. No hard cut, no obvious loop — just more of the shot you already have.
02
Reframed, subject-locked
Every ratio is recomposed around what matters. Faces and action stay centered in 9:16, 1:1, and 16:9 — never cropped to the edge.
03
Every platform, one upload
Reels, Shorts, TikTok, feed, and banner from a single source. Export the full set in the sizes each channel actually asks for.
04
Up to 4K, in minutes
Renders run in the cloud and land at full resolution. Drop a clip, get a platform-ready set back in minutes — nothing to install.
From upload to a full set
The whole pipeline is one flow — extend the shot, reframe it for every screen, and export the pack. No desktop editor, no manual crops.
01
Drop your clip
Upload a video from any source. aivideoextend reads its motion, lighting, and grain before it touches a single frame.
02
Extend the shot
Pick how much longer you need. New footage is generated to continue the scene, seamlessly joined to your original.
03
Reframe every ratio
Choose your targets — 9:16, 1:1, 16:9. Each one is recomposed to hold your subject in frame, not just center-cropped.
04
Export the set
Approved cuts render up to 4K and download as a platform-ready pack. No watermarks on paid plans, nothing to clean up.

Editors stopped reframing by hand
Video editors, social teams, and motion designers use aivideoextend where the reframe has to hold up on every screen.
“I used to reframe every cut by hand for three platforms. Now one upload gives me all three, and the subject is always centered.”
Lena Ortiz
Video editor
“The extend is the part I didn't believe until I used it. It continues the shot so cleanly my clients can't find the seam.”
Theo Marchetti
Content creator
“Our social team was drowning in re-crops. aivideoextend gave us Reels, Shorts, and feed from one master in minutes.”
Amara Diallo
Social media lead
“It holds the subject in frame when it reframes. That single thing saves me an afternoon of keyframing per campaign.”
Jonas Lindqvist
Motion designer
“I stretched a six-second product clip to a thirty-second cut on the train to a pitch. Nobody could tell where the original ended.”
Priya Raman
Agency producer
“Fewer exports to babysit, every one already the right size. My camera roll finally matches what each platform wants.”
Marcus Cole
Filmmaker
