The best free AI video extender going into 2027 depends on where your clip came from: Magic Hour adds 4 seconds to a phone clip with no account, the tool that made an AI clip extends it best, and a series built shot by shot is best continued from the last frame. The ground moved this month: Google took free extension out of Flow on November 5, 2026. We re-checked 14 tools on their own pages on November 9, 2026.
Find your clip on the left; the free pick is on the right.

Which video extender takes your clip? Start with where it came from
What a video extender accepts as input is the first thing to check before you upload.
A clip you filmed on your phone
You need a video extender that takes outside footage. Six tools on our list say they do: Magic Hour (up to 200 MB), ExtendAI Video (MP4, MOV or WebM up to 50 MB), PixVerse (MP4 or MOV, 50 MB, 30 seconds), ClipTrend (MP4 or MOV, 3 to 10 seconds, 100 MB), Picwand and the Gemini API. In Premiere, Generative Extend adds up to 2 seconds on your timeline.
A clip one AI tool already made
Go back to the tool that made it; its native video extender knows the model's motion and grain, so the join hides best there:
- Kling extends an AI-generated video 4 to 5 seconds at a time, "reaching a total length of up to 3 minutes".
- Midjourney videos start at 5 seconds and extend up to 4 times, to a 21-second maximum.
- Runway runs Seedance 2.5 with an Extend mode that continues "an existing video forwards or backwards from a prompt".
- Gemini Omni 1.2 extends its own clips, spoken lines included.
One shot of a series you are building shot by shot
Here a video extender is the wrong tool. A series needs each shot to start where the last one ended but go somewhere new: a new line, another character, a different camera. That is continuing from the last frame: the final frame of shot one becomes the first frame of shot two, and you write what happens next. Dreamina's own guide calls this "a separate continuation shot". On Movoa, 69 of the 110 subscribers whose prompts we read on November 3, 2026 were doing it by hand with screenshots, which is why every finished clip now has a Continue from this clip button.
A shot that has to be one long take
If you need one continuous 30-second shot, generate it in one pass instead of extending a shorter clip. Going into 2027, two models render 30 seconds in a single run:
| Model | Longest single clip | Where it runs |
|---|---|---|
| Kling 4.0 | 30 s | Kling (paid plans) |
| Seedance 2.5 | 30 s | Movoa (paid plans), Runway, Pika (paid plans) |
| Gemini Omni 1.2 Flash | 15 s | Google Vids (3 free a month), Flow, Gemini API |
| MiniMax H3 | 15 s (4 s on a free account) | Movoa |
| Grok Imagine Video 1.5 | 15 s | Movoa (paid plans) |
| Veo 3.1 Fast | 8 s | Movoa (paid plans) |
Lengths from each vendor's page and Movoa's generator, read November 9, 2026.
Not everything sold as a "video extender" generates new footage. When we checked on November 9, 2026, extend.video looped the clip, slowed it down or froze the last frame in your browser. That pads a beat, but nothing new moves.

The best free video extender for each kind of clip
Movoa: the best free video extender route for an AI series
Press Continue from this clip on any finished clip and its last frame drops in as the first photo of a new photo-to-video run, so shot two starts from the frame shot one ended on. Each step is a new clip made from that frame. On a free account each step is a 4-second MiniMax H3 clip at 480p, every step comes with its own sound, and you can keep pressing it with no cap on steps. Save each person once under Characters so their look is one tap away in the next prompt.
A free step carries one picture, the last frame. Adding a saved character's photos on top of it, or pinning the shot between a first and a last frame, comes with a plan: Starter is $14.90 a month and also brings 768p, H3 steps up to 15 seconds, and Grok Imagine, Veo 3.1 and Seedance 2.5 clips of up to 30 seconds, with commercial use.
For a series it is the best free route on this list, and the only one where a free account chains steps with no cap, each with its own sound.
Pick it if: your series runs on the same characters across many shots and each shot needs its own action and its own line. Make the first shot, then press Continue from this clip.
Magic Hour: best video extender for a phone clip, no account
The Magic Hour video extender page reads "Upload a video and extend it with AI, free, no sign up". The free tool adds 4 seconds automatically, up to 200 MB, and "extensions use the shared allowance of 3 free video generations per day". Signing up adds an optional prompt and audio guidance; Magic Hour's own guide says paid plans include commercial use and watermark-free exports.
Pick it if: you shot something that ends a beat too early and want to see 4 more seconds today.
ExtendAI Video: a video extender with no account, 5 or 10 seconds
This video extender gives you 3 free credits a month without an account, reset on the first day of each month. Five added seconds cost one credit and ten cost two, and a finished result can be continued by another 5 seconds. It also takes a JPG, PNG or WebP up to 10 MB as a first frame.
Pick it if: you want to choose the length yourself and three extensions a month is enough.
PixVerse: a video extender for uploads up to 30 seconds
PixVerse's documented Extend API accepts "a PixVerse-generated source video or an uploaded external video", with uploads of up to 50 MB and 30 seconds. Its free Basic plan lists 60 starting credits and 30 a day, renewed at 00:00 UTC; the page does not say what one extension costs. Standard adds watermark-free output up to 720p.
Pick it if: your source clip is longer than the 10 seconds ClipTrend allows.
Gemini Omni 1.2: extends uploads, through the API
Google's API docs let you extend "uploaded or model-generated videos (including 15-second clips) by 3 to 10 seconds per turn", up to 30 seconds in total, and the model reads the last 10 seconds as context. It cannot do two things. First, you "cannot extend an uploaded video where someone is talking to add additional dialogue"; speech is supported only when you extend a clip Omni made itself. Second, extending uploads is not available in the EEA, Switzerland or the UK.
Pick it if: you build with the API and your source clip has no dialogue.
Google Flow and Google Vids: paid extension, free long takes
Flow's help page now says: "On November 5, 2026, Veo Extend was retired. To extend a video, you must be a Google AI Plus, Pro, or Ultra subscriber and use Omni Flash 1.2." For free users, Google's better offer is a longer first take: "anyone with a Google account" can make "up to three 15-second videos per month in Vids at no cost".
Kling: the longest video extender chain, and now 30 seconds in one go
Kling's guide says an AI-generated video "can be further extended by 4-5 seconds and allows for multiple continuations, reaching a total length of up to 3 minutes". On its membership page, read November 9, 2026, Kling 4.0 is listed with "native 30s-generation", so a 30-second shot no longer needs a join at all. The $0 Basic plan has no monthly credits, and commercial use and brand watermark removal start at Standard ($6.99 the first month, then $8.80).
Pick it if: your clip is already a Kling clip and you want it to run for minutes.
Midjourney, Runway and Adobe Premiere
- Midjourney: video starts at 5 seconds; extend it up to 4 times, to 21 seconds. All Midjourney plans are subscriptions, so there is no free route.
- Runway: Seedance 2.5 Extend is one of the few video extender modes that goes backwards as well as forwards. Runway's help centre also suggests the other classic route: combining generated clips in an editor.
- Adobe Premiere: Generative Extend, the video extender inside Premiere, adds up to 2 seconds of video or 10 seconds of audio to a clip already on your timeline; video clips need to be at least 2 seconds long. Good for covering a cut, not for a new scene.
Pika, Dreamina, Picwand and ClipTrend
- Pika has a free plan whose exports carry no watermark; its pricing page does not describe a video extender, and Seedance 2.5 starts on paid plans from $10 a month.
- Dreamina gives US accounts 120 credits a day, with Seedance 2.0 among the free models, and describes both an extension mode and a separate continuation shot.
- Picwand's video extender adds 4 to 15 seconds and says it can generate new scenes "before or after your original clip".
- ClipTrend's video extender runs Kling Extend Beta on 3- to 10-second uploads at 21 credits a pass, from a $19.90 pack of 500 credits, with watermark-free MP4s on every tier.
Does a video extender keep the sound across the join?
Video extender pages talk about frames and rarely about sound, yet a broken line of dialogue is the first thing a viewer notices. Here is what each page actually says.
| Video extender | What happens to sound when you extend |
|---|---|
| Movoa | Every step is generated with its own sound track |
| Gemini Omni 1.2 API | Its own clips can gain new speech; uploads with someone talking cannot get new dialogue |
| Adobe Premiere | Audio can be extended separately, up to 10 seconds |
| Magic Hour | Audio guidance is available in the full tool after sign-up |
| ExtendAI Video, PixVerse, Kling, Picwand | Not stated |
For a cleaner cut with any video extender, do these three things:
- Never split a sentence across a join. End each step after a line lands, then start the next line in the next step.
- Leave half a beat of quiet at the end of a step. The cut point is easier to hide in a pause than mid-word or mid-note.
- Line up joins by ear. In the editor, put the cut where the sound sits right and let the repeated frame fall where it may.
Music is the exception: none of these pages promise to carry an existing song across an extension, so keep the track on its own layer in your editor and lay it over the joined clips at the end.
Keep faces from drifting when you use a video extender
These four fixes against drift come from the video extender guides of PixVerse, Google and Kling and from building series on Movoa.
End each step mid-motion
A video extender only sees the last moments. A walk, a pan or a turn in progress gives it something to carry on; a fade or a blurred subject gives it nothing. PixVerse's advice: ask for "a restrained continuation rather than adding a second event". A prompt in that spirit: "She keeps walking toward the door at the same pace, the camera follows, nothing else enters the frame." Our MiniMax H3 prompt guide covers how to write that next beat.
Keep the model, ratio and resolution the same
Switching models between steps changes the grain, the colour and how things move, and the join shows. Crop the source to its final ratio before the first step, not afterwards. To keep the background still, keep the camera move small and do not describe new scenery in the next prompt. Google says Omni 1.2 Flash shows "less visual drift or morphing across motion and camera transitions", and that characters stay consistent when you extend a clip into a longer sequence; that holds when the whole chain stays on one model.
Pin where the shot lands
If you know the last picture of a step, give it as an end frame. The Gemini API supports first- and last-frame interpolation from 3 to 10 seconds; on Movoa, H3 runs from a start frame to an end frame on every paid plan.
Join in an editor and trim the repeated frame
Last-frame chains give you one file per step. Put them in order in any editor (CapCut works on desktop and phone; its AI extension mode lives in Dreamina, its ByteDance sister app), trim the duplicated frame at each join, and play every join at normal speed before you make the next step.
Free vs paid video extender plans for 2027
Across these video extender plans, paying most often buys longer steps, higher resolution, files without a watermark, or the right to use the result commercially; the rows below show which plan says which.
| Tool | Free gets you | A paid plan adds |
|---|---|---|
| Movoa | H3 480p 4 s steps with sound, no cap on steps | 768p, H3 steps up to 15 s, several photos or an end frame per step, Grok, Veo and Seedance (30 s on Seedance 2.5), commercial use |
| Magic Hour | 4 s automatic extension, 3 a day | Prompted extensions, commercial use, watermark-free exports |
| PixVerse | 60 credits, then 30 a day | Watermark-free output up to 720p on Standard |
| Kling | Basic plan, no monthly credits | 660 credits a month on Standard, commercial use, watermark removal |
| Pika | Free plan, no watermark | Seedance 2.5 from $10 a month, commercial license on Creator |
| Google Flow | No extension | Omni extension on Google AI Plus, Pro or Ultra |

Video extender FAQ
What is the best free AI video extender for 2027?
For a clip you filmed, Magic Hour: 4 seconds per extension, 3 a day, no account. For a series with the same characters across many shots, Movoa's Continue from this clip makes each next shot as a new 4-second H3 clip from the last frame, with sound, free and with no cap on how many. For one long take with no join, Google Vids makes three new 15-second clips a month for free; that is generation, not extension.
Can I extend a video I filmed on my phone for free?
Yes. Magic Hour (200 MB) and ExtendAI Video (50 MB) take phone clips without an account, and PixVerse takes uploads up to 30 seconds, though its page does not say how many free credits an extension uses. On Movoa, upload a screenshot of the clip's last frame as the photo and write what happens next.
Is there an AI video extender with no sign-up and no limits?
Not both at once. Magic Hour allows 3 a day without an account and ExtendAI Video 3 credits a month. On Movoa you can make a clip without an account, and a free account chains steps with no cap.
How long does an extension take to generate?
ExtendAI Video says most short jobs finish in about one or two minutes, and ClipTrend says 60 to 120 seconds. The other pages do not give a time.
Does "no restrictions" mean no content rules?
No. Free, no sign-up and no limits describe how many clips you can make, not what you can make. Each tool has its own content rules.
How long can an AI video be in one go now?
Thirty seconds, on Kling 4.0 and Seedance 2.5. Gemini Omni 1.2 Flash, MiniMax H3 and Grok Imagine Video 1.5 go to 15 seconds.
Can a video extender add dialogue to my clip?
Sometimes. The Gemini API adds speech when extending its own clips, not uploads where someone is already talking. On Movoa each continued step is a new clip generated with its own sound, so write the next beat into the next step's prompt rather than stretching the old one.
Is there a video extender app, and is a mod APK safe?
Movoa, Magic Hour and ExtendAI Video run in a phone browser, no app needed. Skip modded APKs: that is code from someone you cannot check.
Does my own GPU affect the result?
Not with browser tools: Movoa, Magic Hour, PixVerse and the rest generate in the cloud, so your graphics card does not change the clip. Only local setups such as ComfyUI with open video models depend on your own GPU.
