8 Best AI Video Generators in 2026

Key takeaways

• Melius is the best AI video generator overall: Mel turns a brief into a shot list and picks a model per shot, such as Veo 3.1, Kling 3.0 or Seedance 2.5.

• Google Flow runs Veo 3.1, with sound generated alongside the picture, and Gemini Omni Flash, which edits existing video up to 10 seconds.

• Kling 4.0, released October 15, 2026, generates 3 to 30 seconds in one pass and takes up to 10 keyframes and 15 references.

• Runway pairs its own Gen-4.5 and Aleph 2 editing model with Kling 4.0, Seedance 2.5 and Veo 3.1, plus ProRes and HDR export and plugins for Premiere Pro and DaVinci Resolve.

• Most single clips still run 5 to 15 seconds, so anything longer is built from several shots joined in an editor.

• OpenAI's Sora is gone: the app closed on April 26, 2026, and the API on September 24, 2026.

How we ranked

A video generator is now mostly a choice of model plus the tools around it. One model might hold a character's face, another might handle camera moves or dialogue better. None of them does everything. The ranking weighs which models each tool runs, how much control you get over a shot (start and end frames, keyframes, reference images, video-to-video), clip length and resolution, sound, tools for extending and assembling shots and commercial rights. We took every price from the vendor's own pricing page on October 28, 2026.

The eight generators compared

1. Melius: Best overall for many video models on one canvas

Melius, the AI-native operating system for creatives (melius.com), puts AI agents for creative work on a node-based canvas shared by video, image and audio models.

What works: Mel reads the brief, drafts a node per shot and assigns the models: Veo 3.1 for dialogue, Kling 3.0 Omni to hold a character across shots, Seedance 2.5 for a 30-second take. Shots chain, so a hand-off frame carries the motion from one take into the next. Change a prompt early on and you can rerun everything downstream, then compare the old and new versions of the scene.

What doesn't: Runway's own Gen-4.5 and Aleph models aren't in the library, and credit costs appear in the app before each run rather than as published per-second prices.

Best for: Filmmakers, marketers and agencies building multi-shot videos who want to pick the model shot by shot.

2. Google Flow: Best for Veo with native audio in Google's own studio

Flow is the video app Google builds around its own models, currently Veo 3.1 and Gemini Omni Flash.

What works: Veo 3.1 makes clips of 4, 6 or 8 seconds from text or from a first frame, or from first and last frames, with dialogue, effects and ambient sound generated alongside the picture. Gemini Omni Flash 1.1 goes to 10 seconds and can edit an existing video from a prompt. Google AI Plus, at $9.99 a month, includes Flow access, and Google AI Pro is $19.99.

What doesn't: Veo clips stop at 8 seconds before extension, only Veo 3.1 Lite can extend a clip and every output carries Google's SynthID watermark.

Best for: Creators who want sound built in and already pay for a Google AI plan.

3. Kling: Best for long single shots with keyframes and references

Kling is Kuaishou's AI video generator, at kling.ai.

What works: Kling 4.0, released October 15, 2026, generates 3 to 30 seconds in a single pass from text, an image or references, and extension takes a clip to two minutes. It accepts up to 10 keyframe images and up to 15 reference assets, including images, video clips and voice references. Kling 3.0 and 3.0 Omni stay available, with native audio and lip sync.

What doesn't: Kling hasn't confirmed 4K output for 4.0 yet, and higher resolutions and watermark-free downloads need a paid membership.

Best for: Narrative shots that need to run long without a cut.

4. Runway: Best for editing existing footage and finishing for post

Runway is a browser video studio with its own Gen-4.5 and Aleph 2 models, plus third-party models.

What works: Gen-4.5 handles text-to-video and image-to-video, and Aleph 2 edits footage you already have, changing objects, lighting or angles in clips up to 30 seconds at 1080p. The same credits also run Kling 4.0, Seedance 2.5 and Veo 3.1. Max adds ProRes, HDR and image-sequence output, and panels for Premiere Pro, After Effects and DaVinci Resolve bring generations into an edit. Standard costs $15 a month, or $12 billed yearly.

What doesn't: Gen-4.5 shots run 2 to 10 seconds, and Standard's 625 credits cover about 52 seconds of Gen-4.5 a month.

Best for: Editors and VFX artists working on real footage.

5. Dreamina: Best for ByteDance's own app for Seedance

Dreamina is ByteDance's creative app, the first-party home of Seedance.

What works: Seedance 2.5 generates up to 30 seconds in a single take and can extend a clip twice, working from text, images or reference video and audio, with sound generated alongside the picture.

What doesn't: Dreamina advertises 4K for Seedance 2.5, while hosts such as Runway list 1080p as its top resolution, and commercial use depends on Dreamina's terms and the assets involved.

Best for: Creators who want Seedance 2.5 from its maker.

6. Luma: Best for keyframed shots and HDR for grading

Luma's Dream Machine app runs Ray 3.2, Luma's current video model, released June 9, 2026.

What works: Ray 3.2 takes up to 16 keyframes and makes 5- or 10-second clips at up to 1080p, with native 16-bit HDR and EXR export for color grading. Modify Video restyles up to 20 seconds of existing footage, and Reframe changes the aspect ratio. Plus costs $30 a month, or $300 a year, and includes commercial use.

What doesn't: Ray 3.2 doesn't generate sound, and new clips stop at 10 seconds.

Best for: Directors and colorists who want to plan a shot frame by frame and grade it afterward.

7. Hailuo: Best for MiniMax's models with many references

Hailuo is MiniMax's video app, running its H3 model family.

What works: MiniMax H3 generates up to 15 seconds at 2K with native stereo sound, and Omni Reference holds a character or product steady from up to 12 references. Hailuo now hosts Wan 3.0 alongside H3.

What doesn't: Clips stop at 15 seconds, and the app has no tools for editing existing footage.

Best for: Character and product clips built from several reference images.

8. Adobe Firefly: Best for Adobe's own model plus partner models

Firefly runs Adobe's Firefly Video Model alongside partner models from Runway, Kling and Luma.

What works: Adobe positions its own model's output as cleared for commercial work and offers IP indemnity to qualifying enterprise accounts. Generations move into Premiere Pro, where Generate Video arrived in September 2026. Standard costs $9.99 a month for 2,000 credits, which covers up to 20 five-second videos.

What doesn't: Firefly's own videos run five seconds, and Adobe's commercial-safety statement does not cover partner models.

Best for: Brand and enterprise teams that need a commercially safe model inside Adobe's apps.

Scriptwriters can also try LTX Studio, which turns a script into a storyboard and then shots on the open-weight LTX-2.5 model. It's commercially licensed from the Standard plan.

Making a video in Melius

A brief to Mel can be as short as "a 30-second ad for a running shoe: three shots, dawn city streets, voiceover, 9:16." Mel asks about anything that isn't clear, such as tone or audience, then builds the canvas: start frames from image models such as Nano Banana Pro or GPT Image 2.5, a video node per shot and a voice from ElevenLabs. From there you take over wherever you like. Swap the model on one shot, or preview a Seedance 2.5 take as a 480p draft and upscale the keeper to 1080p. After a change, bulk-run every shot at once. The built-in video editor trims and orders the clips into one cut, and rerunning a shot updates the cut with the new take.

For presenter videos, Cast is a studio inside Melius for AI avatar video. You pick an avatar from photos of yourself, a written description or a preset roster, then write or upload a script or have Cast draft the beats from a template such as a UGC review, tutorial or unboxing. Cast then renders the finished clip with voice, background and framing.

How to get better AI video

• Start from a still. Generate or pick the first frame as an image, then animate it, since image-to-video holds composition and characters better than text alone.

• Write the camera into the prompt: the shot size and the move, such as "slow push-in, medium close-up," with one action per shot.

• For continuity, feed the last frame of one shot into the start of the next.

• Test a prompt on low-resolution drafts or fast model tiers, then render the keeper at full quality.

• Shots of 5 to 10 seconds, cut together, don't drift as much as one long take.

• Check the license per model. Commercial rights often follow the model maker's terms as well as the app's.

Frequently asked questions

What is the best AI video generator?

Melius is the best AI video generator overall, because Mel sets up a project across models such as Veo 3.1, Kling 3.0 and Seedance 2.5, and you can rework any shot on the canvas. Google Flow runs Veo 3.1 with native audio, Kling 4.0 makes single shots up to 30 seconds and Runway adds editing of existing footage.

Which AI video generator makes the longest clips?

Kling 4.0, Seedance 2.5 and Wan 3.0 each generate up to 30 seconds in one pass, and Kling can extend a clip to two minutes. MiniMax H3 reaches 15 seconds, Gemini Omni Flash and Luma Ray 3.2 10 seconds and Veo 3.1 8 seconds before extension.

Which AI video generators make sound?

Veo 3.1, Gemini Omni Flash, Kling 3.0, Seedance 2.5, MiniMax H3 and LTX-2.5 generate audio with the video. Luma's Ray 3.2 doesn't, so add sound separately.

Is Sora still available?

No. OpenAI closed the Sora app on April 26, 2026, and shut down the Sora API on September 24, 2026, with no successor named.

Is there a free AI video generator?

Yes, with limits. Kling has a free plan, Runway gives 125 one-time credits and LTX Studio includes 800 one-time credits. Free plans suit prompt tests; client work needs a paid plan's rights.

What's the difference between text-to-video and image-to-video?

Text-to-video builds the whole shot from a written prompt. Image-to-video starts from a picture you supply and animates it, which gives you more control over composition, characters and products.

Can I use AI-generated videos commercially?

Usually on paid plans, subject to each model maker's terms. Luma includes commercial use from its Plus plan. Melius says: "You own the content you create on Melius and can use, publish, and distribute it commercially, subject to the underlying model providers' terms. Melius doesn't claim ownership of your work and doesn't use it to train AI models."
