Best AI video generation tools in 2027 and what each can do

An AI video generator is software that makes video clips from text, images or reference footage. As of 11 November 2026 Google's current one is Gemini Omni, and OpenAI has discontinued Sora. Runway, Kling AI, Luma and Adobe Firefly also generate clips, CapCut and Descript edit, and HeyGen, Synthesia and ElevenLabs cover avatars and dubbing.

Which AI video generators make clips from text or images?

Five tools generate clips. "Best" here means the job each is built for, checked on the vendor's own pages on 11 November 2026. Clip length or resolution is stated only where a vendor page gives it.

Gemini Omni

Gemini Omni is Google's video model for the Gemini app, Google Flow and YouTube Shorts. Google introduced Gemini Omni Flash on 19 May 2026 as a model that creates from any input, starting with video, and released Gemini Omni 1.2 Flash on 5 November 2026. A creator can upload a clip and ask for a change in plain language. Google's help page states the limits in the Gemini app: clips run 3 to 10 seconds, or up to 15 seconds for AI Ultra users, and a personal account needs a Google AI plan. Every Omni video carries Google's invisible SynthID watermark.

Runway

Runway is a cloud creative platform to generate and edit video, images and audio in one workspace. Its help page says Runway Agent can make text-to-video or image-to-video, single shots or multi-shot sequences, and restyle an existing clip. An ad team can turn one product shot into several scenes. The limit is in Runway's own wording: audio is native "depending on the model". Runway says users retain ownership of what they generate as between the user and Runway, and that it adds C2PA provenance signals, which it calls not a complete solution to misuse.

Kling AI

Kling AI is a video and image generator whose home page announces Kling 4.0 and a Canvas where an agent helps write scripts and generate images, videos and storyboards. A short-film maker can plan shots as storyboards before generating them. The address changed: klingai.com now redirects to kling.ai. The page does not state clip length, so check it in the app. The terms of service say users may not impersonate any person or entity.

Luma

Luma is a creative platform; the address that used to serve its Dream Machine product now redirects to a page titled "Creative agents for creative professionals". The page says Luma unifies specialised multimodal models into one workflow and lists short-form video ads, localising a video into several languages and turning a podcast clip into a video. A small brand can make a social ad from a brief. The limit is that the page states no clip length or resolution, and the product now emphasises agents over a single text box.

Adobe Firefly

Adobe Firefly is Adobe's creative studio for images, video and audio. Adobe's page says its free AI video generator turns a prompt or an image into a clip using the Firefly Video Model and partner models, and that videos from the Firefly model are safe for commercial use. A marketer can generate a product video for a campaign. The limit is that this statement covers Adobe's own model: for partner models, an Adobe Stock guide says Adobe cannot verify the training data or whether outputs contain third-party IP, so their terms must be read.

Which AI tools edit video and add captions or voices?

Two tools are editors first, with generation added.

CapCut

CapCut is an editing app whose site lists Video Studio, a timeline video editor, auto captions and EditPilot, which turns a creator's direction into edits on the timeline. A student can caption and trim a short video in one place. CapCut says it informs users when AI features are used and works to provide labels or watermarks. Its March 2026 post on the Dreamina Seedance 2.0 model says AI content gets visible watermarks and C2PA Content Credentials, and that the first rollout restricted videos made from images containing real faces.

Descript

Descript is an AI video and audio editor that makes editing as easy as editing text: it records, transcribes, edits and publishes in one tool. A podcaster can cut a recording by deleting words in the transcript. The limit is a consent step: Descript's Help Center says a custom voice clone is created by recording a consent statement, which must be in English even for other-language audio, and a clone for someone else needs that person's recorded consent.

Which AI tools make avatars and dub videos?

Three tools replace filming or translate existing footage, which brings consent into the picture.

HeyGen

HeyGen is a tool for AI videos with a Personal Avatar, described on its home page as a person's face and voice without filming every video. A trainer can send a monthly update without a camera setup. The limit is consent: HeyGen's Help Center says every video-based Digital Twin needs a short consent video recorded before the avatar is created, and a person making an avatar of someone else needs that person to record their own. The help centre uses the name Digital Twin while the home page says Personal Avatar.

Synthesia

Synthesia is an AI video platform whose site lists avatars, a video generator, dubbing and translation. A company can turn a training script into an avatar video. Its documentation says a personal avatar needs a consent video recorded live, which cannot be uploaded even when pre-recorded footage is used, and which must show the same person as the avatar footage. That live step is the limit: the person in the avatar has to record the consent themselves.

ElevenLabs

ElevenLabs is a voice company whose dubbing studio localises content across 90+ languages. Its page says each translation arrives in a voice clone of the original speaker, preserving identity, pitch and tone, and that phrasing is adapted for each target language. A lecturer can dub an English recording for a Hindi audience. The limit is permission: because cloning is automatic according to the page, the user must have the speaker's agreement before dubbing.

How do the ten AI video tools compare?

The table gives each tool's best use, its main limit and the provenance or consent step its vendor documents.

What happened to Sora and Veo?

OpenAI's Help Center says the Sora web and app experiences were discontinued on 26 April 2026 and the Sora API on 24 September 2026, so Sora is not a current option. Older lists still include it.

Veo has a similar naming problem. Google's Gemini API documentation says the Veo 3.1 Preview models in the Gemini API were shut down on 22 October 2026, and directs developers to Gemini Omni Flash. Veo 3.1 Fast still appears as a partner model inside Adobe Firefly's video picker, and Pika's home page lists Seedance 2.5, Kling 4.0, Veo 3.1 and Wan 3.0 in one platform. A tool name and the model underneath it are therefore different things, and the model named inside a tool can change.

Which AI video tool should you choose?

Choose by the job and the proof you need to give. One line per situation:

• A first clip from a prompt or photo, inside tools already used: Gemini Omni in the Gemini app, or Adobe Firefly.
• Several connected shots or a restyled clip: Runway.
• Storyboards before generation: Kling AI.
• Captions, trimming and timeline edits: CapCut or Descript.
• A presenter video without filming: HeyGen or Synthesia, with the person's own consent video.
• A recording in more languages: ElevenLabs, with the speaker's agreement.

Can AI video tools make a full movie?

Not from one prompt. The clip lengths on vendor pages are short: Google states 3 to 10 seconds in the Gemini app and up to 15 seconds for AI Ultra users and in the API. Runway describes multi-shot sequences and Kling AI a storyboard canvas, but a longer film still means planning shots, keeping characters consistent and editing the clips together in an editor such as CapCut or Descript.

Do AI videos have to be labelled, and what about consent?

There is no single global rule, and what follows describes what published rules and vendors say, not legal advice. India's Information Technology (Intermediary Guidelines and Digital Media Ethics Code) Rules, 2021, as updated by the Ministry of Electronics and Information Technology on 10 February 2026, define "synthetically generated information" as audio, visual or audio-visual content created or altered so that it appears real and depicts a person or event indistinguishably from the real thing, and exclude routine editing such as colour adjustment or noise reduction.

The duties sit on intermediaries. Under rule 3(3), a tool that lets users create such content must label it prominently and embed permanent metadata or other provenance markers where technically feasible. Under rule 4(1A), a significant social media intermediary must ask users to declare whether content is synthetic and label it once confirmed. A MeitY notice of 21 April 2026 shows draft changes proposing a continuous visible label on video, so the current text should be checked.

Platforms add their own rules. YouTube Help says creators must disclose realistic AI-generated or altered content, such as making a real person appear to say or do something they did not, through the "AI use" setting at upload. On consent, Descript, HeyGen and Synthesia each require a recorded consent step for a person's voice or avatar, and Kling AI's terms bar impersonation. For Descript, HeyGen and Synthesia, the person's own recorded consent is the minimum.

Where does the MIT Open Learning programme fit?

AI video tools are an application of multimodal models, and knowing how those models work helps a user judge their limits. The Universal AI Program by MIT Open Learning is a self-paced online programme from MIT Open Learning, delivered in India in cooperation with Masai on the MIT Learn platform, that builds AI fluency without needing a coding background, with modules on Python, machine learning, deep learning, large language models, generative AI and ethics, plus industry-specific modules. Its modules include Multimodal AI and Deep Learning and Computer Vision.

Frequently asked questions

Which AI video generator is best?

No generator is best for every job. Gemini Omni suits conversational edits inside Google's apps, Runway suits multi-shot work, Adobe Firefly states that its own model's videos are safe for commercial use, and CapCut and Descript suit editing. The criterion is the job, the clip length the vendor states and the rights or consent step it documents.

Can AI video tools make a full movie?

Not in one step. Vendor pages describe short clips: Google states 3 to 10 seconds in the Gemini app and up to 15 seconds for AI Ultra users. Tools such as Runway and Kling AI add multi-shot sequences and storyboards, but a film still needs planning, consistent characters and editing in a tool such as CapCut or Descript.

Do AI videos have to be labelled?

It depends on the tool and the platform. India's IT Rules, updated on 10 February 2026, require intermediaries that offer generation tools to label synthetic content and add provenance metadata, and require large social media platforms to ask users to declare it. YouTube requires disclosure of realistic AI content at upload. This is a description of rules, not legal advice.

Is OpenAI Sora still available?

No. OpenAI's Help Center says the Sora web and app experiences were discontinued on 26 April 2026 and the Sora API on 24 September 2026. The same page says Sora content can still be exported at sora.chatgpt.com/sunset. Older lists that still include Sora are out of date, and Google's video model in its apps is now Gemini Omni.

Did Gemini Omni replace Veo?

In the Gemini API, Veo 3.1 Preview was replaced: Google's documentation says those models were shut down on 22 October 2026 and directs developers to Gemini Omni Flash. In consumer products, Google introduced Gemini Omni on 19 May 2026 for the Gemini app, Google Flow and YouTube Shorts. Veo 3.1 Fast still appears as a partner model inside Adobe Firefly.

Is it legal to make an AI video of a real person?

Rules depend on the country, the purpose and consent, and this is not legal advice. Several vendors documented here require consent: Descript, HeyGen and Synthesia each ask for a recorded consent step, and Kling AI's terms bar impersonation. India's IT Rules ask tool providers to use technical measures against synthetic content that falsely depicts a person.

Next step

Take one short script, generate a clip in two of the tools above, and compare what each one labels, restricts and asks for in consent. To understand the multimodal models behind these tools, the Universal AI Program by MIT Open Learning page lists the modules and how the programme is delivered.
