AI video generation went from "wow, that's weird" to "wait, I could actually use this" somewhere around mid-2024. Here in 2025, there are at least a dozen serious players, each one promising to turn your text prompts into professional-looking video. Some of them deliver on that promise.

The problem is, if you want to create something more than a meme or AI slop, generating a clip is only part of the job. Most tools do the generating, then leave you to figure out the rest—editing it, adding captions, fixing mistakes, and somehow getting it from "AI draft" to "thing you'd actually publish." That's where the real work lives, and that's where most AI video tools just shrug and point you toward the export button.

Plus, all the different generative AI models are good at different kinds of video. So you might need to go to one app to create a social clip and another to generate animated titles.

Quick answer:

• The AI video generation space exploded in 2025 — but most tools stop at "meme."
• You generate something, then you're stuck exporting and editing across multiple apps.
• Descript is the AI video generator that works with recorded video—so you can generate, refine, caption, and publish in a single workflow.
• There are dozens of generative video AI models, and more every day. They're all good for certain types of video and certain situations.
• Descript has all the best AI models and a model picker, so you can always pick the right one for the job.
• This guide ranks the top 10 AI video generators and shows why Descript is best for creators who need both speed and control.

The 10 best AI video generator tools

1. Descript — Best all-in-one AI video generator and editor

‎

Descript is an all-in-one AI video generator and editor that lets you create full videos from a text prompt or script, then instantly edit them by editing text — like you're working in a document. It combines AI video generation, editing, voiceover, and captioning into a single workspace, which means you're not constantly exporting and importing between five different apps just to get one video done.

You can generate video from a prompt or from an image using the latest models (Veo 3, Sora, Kling, and others). The AI Video Maker feature creates visuals, voiceover, and layouts from text.

‎But here's where it's different: once the video exists, you edit it by changing the transcript. Cut a sentence, and the video cuts. Rearrange a paragraph, and the footage rearranges with it. Add AI voice cloning with Overdub, apply Studio Sound to fix rough audio, remove filler words automatically, and pull from templates and stock media without leaving the app. With Underlord, Descript's AI editing assistant, you can describe changes in plain language and watch them happen. AI Clips automatically generates highlight reels from long content. You can export in 4K, use brand templates, and collaborate with your team in real time.

Descript is built for creators and marketers who want one platform to generate, edit, and publish videos quickly. It's ideal for explainers, social media content, and brand storytelling — especially when you need to move fast and maintain quality.

Pricing starts with a free plan (with watermark and limited transcription), a Creator plan at $24/month with annual billing, and a Business plan at $50/month that includes team features and AI avatar creation.

Benefits: Descript combines AI generation and editing in one interface, which means you're not stuck with whatever the generator spits out. You can add captions and subtitles automatically, polish the edit by changing text, fix mistakes with Overdub, and export in multiple formats. The collaboration and repurposing tools are excellent. 4K export and AI clip automation save hours.

Drawbacks: AI credit hours are limited on lower tiers, and if you're looking for advanced VFX or cinematic rendering tools like you'd find in a dedicated effects suite, you won't find them here.

Key differentiator: Unlike other tools that stop at generation, Descript is where you finish your videos — polish, caption, and publish without leaving the app.

2. Google Veo 3 — Best for end-to-end cinematic generation

‎Google Veo 3 is one of the most advanced AI video generators available right now. It produces cinematic-quality visuals with realistic motion, lifelike lighting, depth, and physics. If you've ever seen AI-generated video that actually looks like it could have been shot on a real camera, it was probably Veo. It's designed for filmmakers, advertisers, and creatives who need high-production-value footage without the high-production-value budget.

Veo does text-to-video and image-to-video generation, outputs in 4K with camera control, handles lip-synced character voice generation, and integrates with Google Flow editor for scene stitching. It's built for cinematic storytelling, ad creatives, and anything where visual polish matters. And here's the good news: Veo 3 is now available in Descript, which means you can generate stunning cinematic footage and immediately edit it by editing text — no switching between tools.

Pricing is part of Google AI Pro at $19.99/month with 1,000 credits, or the Ultra plan at $249.99/month for watermark-free output and 12,500 credits.

Benefits: The realism and camera effects are industry-leading. Long scene durations and cinematic detail are genuinely impressive. Built-in audio and lip-sync capabilities save steps.

Drawbacks: Watermark removal and per-second costs get expensive fast. Editing flexibility is limited — once it's generated, you're mostly stuck with it.

Key differentiator: 4K-quality cinematic rendering that rivals film production. It's perfect for premium creative assets, but you're paying for that quality.

3. Runway Gen-4 — Best for generative editing and visual FX

‎Runway's Gen-4 and Aleph models push creative boundaries by letting you generate, edit, and transform videos using text prompts. It's become a favorite among video professionals and agencies who want more control over the generative process. Runway doesn't just spit out a clip and wish you luck — it gives you tools to keep shaping it.

The Gen-4 Turbo model handles fast, dynamic generation. The Aleph model lets you edit angles, lighting, and objects. Act-Two gives you character and gesture control. There's even a chat interface for iterative prompt editing, which is surprisingly useful when you're trying to nail a specific look.

It's best for creative professionals, agencies, and visual artists who are experimenting with high-end generative effects and aren't afraid of a learning curve.

Pricing includes a free tier with 125 credits and a Standard plan at $15/month with 625 credits and no watermark.

Benefits: The visual editing and transformation controls are best-in-class. The feature set keeps evolving, and it's ideal for creative experimentation.

Drawbacks: There's a learning curve if you're not technical, and render queue delays under heavy use can be frustrating.

Key differentiator: Powerful post-generation editing that lets you literally "direct" your AI footage after it's created.

4. OpenAI Sora — Best for storyboard-style and community remixing

‎Sora by OpenAI generates videos from text, images, and existing clips, with a focus on visual coherence and remixing. It gives creators an easy way to chain scenes together and experiment with storytelling in a way that feels more iterative and playful than some of the more rigid tools.

Sora uses a storyboard-based generation approach with multiple scenes, includes community remix tools so you can build on other people's work (or let them build on yours), and integrates with ChatGPT for prompt design and iteration.

It's built for experimental storytellers, indie creators, and content remixers who want to play around without committing to a single vision upfront.

Pricing is available via ChatGPT Plus at $20/month, or a Pro plan at $200/month that includes 1080p video, longer clips, and watermark removal.

Benefits: The storyboard approach is intuitive. Remixing and collaboration features are fun. Visual consistency across scenes is solid.

Drawbacks: Access and duration limits on lower tiers are real constraints. Realism is still inconsistent, especially for human motion.

Key differentiator: Scene-by-scene creative control inside a community remix ecosystem, which makes it feel more like a creative playground than a production tool.

5. Synthesia — Best for professional avatar videos

‎Synthesia is the industry standard for AI avatar videos. It's used for training, localization, and corporate communications because it converts scripts into lifelike, multilingual presenter videos at scale. If you've ever sat through a corporate training video with a suspiciously perfect presenter, there's a good chance it was Synthesia.

It supports 140+ languages with realistic lip-sync, offers 125+ avatars plus custom avatar creation, and has script-to-video automation with stock templates. It's built for corporate training, onboarding, explainer videos, and localization at scale — especially when you need the same message delivered in 15 different languages without flying presenters around the world.

Pricing starts with a free plan (3 minutes per month with a watermark) and a Starter plan at $29/month that includes 125+ avatars and 120 minutes per year.

Benefits: High-quality, multilingual avatars. Consistent lip-sync accuracy. Fast turnaround.

Drawbacks: There's an uncanny valley effect at large screen sizes. Creative camera control is limited.

Key differentiator: The most mature, secure, and scalable avatar generator for enterprise use. It's boring in the best possible way.

6. HeyGen — Best for interactive and personalized avatar content

‎HeyGen goes beyond static avatar videos by enabling interactive AI avatars that respond in real time using custom knowledge bases. This isn't just a presenter reading a script — it's an avatar that can actually answer questions and hold conversations.

Features include interactive avatars powered by AI and user data, 175+ languages and dubbing options, and integration for websites, chat, and support flows.

It's best for sales, customer service, and interactive training content where you need the avatar to do more than just deliver information.

Pricing includes a free tier with 3 videos at 720p and a Creator plan at $29/month for 30-minute videos with 1080p export.

Benefits: Interactive, conversational avatars are genuinely impressive. Broad language and voice options. API and embed flexibility.

Drawbacks: Costs increase with volume. Render times for interactive videos can be longer.

Key differentiator: Real-time, knowledge-powered avatars that can interact with audiences dynamically — which is either the future or deeply unsettling, depending on your perspective.

7. InVideo — Best for fast social media videos

‎InVideo AI creates ready-to-publish marketing videos from prompts by combining stock footage, transitions, and voiceover in minutes. It's optimized for speed, which means it's not going to win any awards for artistic vision, but it will get you a decent-looking social video before your coffee gets cold.

Features include text-to-video with stock integration, built-in script generation and AI voiceover, and subtitles with aspect ratio presets for different platforms.

It's built for social media managers and marketers who need quick branded videos and don't have time to mess around.

Pricing includes a free plan with 10 minutes per week (with watermark) and a Plus plan at $35/month for 50 minutes per month with iStock media.

Benefits: Extremely fast output. Built-in stock and script generation. Multi-language support.

Drawbacks: The style is template-heavy, and customization options are limited.

Key differentiator: The fastest AI video generator for social content and short-form publishing. You trade creative control for speed, and sometimes that's the right trade.

8. Pictory — Best for repurposing long content

‎Pictory converts long-form content — blog posts, webinars, transcripts — into short, branded videos with captions and voiceovers. If you've ever stared at a 3,000-word blog post and thought "this should be a video," Pictory is built for that exact moment.

Features include URL-to-video and script-to-video conversion, automatic highlights from long videos, and brand kits, templates, and captions.

It's designed for marketers and content teams who are turning text or webinars into shareable clips at scale.

Pricing starts with a Starter plan at $25/month for 30 videos per month and a Premium plan at $49/month for 60 videos per month with 20 hours of transcription.

Benefits: Great for repurposing content. Simple and intuitive editor. Built-in caption and branding tools.

Drawbacks: Visuals feel templated. Limited control over generation style.

Key differentiator: The best repurposing-focused AI tool for turning text into video at scale. It's not trying to be cinematic — it's trying to be efficient.

9. Luma Dream Machine — Best for brainstorming and concept visualization

‎Luma Dream Machine focuses on creative ideation and stylized visuals. It helps creators visualize prompts and iterate quickly, which makes it great for the early stages of a project when you're still figuring out what you want.

Features include text-to-image and image-to-video modes, an interactive "board" system for iteration, and stylized rendering for 3D, cartoon, or concept art looks.

It's built for storyboarding, animation concepts, and idea exploration — the messy, fun part of the creative process before things have to look polished.

Pricing starts with a Lite plan at $9.99/month with 3,200 credits and 1080p output.

Benefits: The creative process is engaging and gamified. It's great for pre-visualization and animation teams.

Drawbacks: It's not designed for polished, realistic outputs. Render times can be slower during high traffic.

Key differentiator: The most creative-friendly AI tool for experimenting with styles and concepts. It's a sketchbook, not a printing press.

10. Vyond — Best for animated explainers

‎Vyond helps businesses generate animated character videos from scripts using AI. It's widely used for training and internal communications because it produces clean, professional animations quickly — even if those animations sometimes feel a little... corporate.

Features include text-to-scene and character animation, scene and voiceover automation, and a large library of business-themed templates.

It's built for HR teams, educators, and corporate trainers who need animated explainer videos that won't offend anyone or cause confusion.

Pricing starts with a Starter plan at $99/month (or $58/month with annual billing), plus Professional and Enterprise tiers with collaboration features.

Benefits: Rapid animated content creation. Business-ready templates. Enterprise-level compliance.

Drawbacks: Limited visual customization. The animation style can feel generic.

Key differentiator: The best business-focused animation generator for professional training videos. It's the sensible, reliable choice that won't surprise anyone.

Build a winning AI video workflow with Descript

Here's how to actually use AI video generation as part of a real workflow, not just as a party trick:

Generate initial clips or scripts using Descript's AI Video Generator

Start with a prompt or upload an image reference. Let the AI build the foundation.

Edit with text — cut, rearrange, and polish instantly

Once you have generated footage, edit it like a document. Delete a sentence in the transcript, and the corresponding video disappears. Rearrange paragraphs, and the clips move with them. This is where most other tools leave you stranded with an export button and a prayer.

Add branded captions, stock B-roll, and music

Layer in your brand kit, drop in stock footage, add a soundtrack. All without leaving the app or juggling multiple subscriptions.

Use Overdub to fix narration or add new voice lines

Recorded something wrong? Don't re-record. Just type the correction and generate it in your voice (or a stock voice) using AI.

Export multiple aspect ratios (square, vertical, widescreen) for social channels

One video, multiple formats. Descript handles the resizing and cropping so you're not manually adjusting layouts for every platform.

Repurpose long videos with AI Clips for shorts or teasers

Take a 20-minute video and let AI Clips find the best moments. Turn one piece of content into five.

Collaborate and share directly for feedback and version control

Share a link. Collect comments. Make revisions. No endless email chains with "FINAL_v7_ACTUAL_FINAL.mp4" attached.

The future of AI video generation

Most AI video tools stop at generation. You get a clip, you export it, and then you're on your own. Descript goes all the way to ready-to-publish. Whether you're creating ads, explainers, or podcasts with visuals, Descript's text-based editing makes video creation feel less like wrestling with software and more like writing.

The future of AI video isn't just about better generation — it's about smarter workflows. It's about tools that understand the whole job, not just one step. It's about speed without sacrificing control, and automation without losing your voice.

Sign up for Descript — generate, edit, and publish your next video all in one tool.

AI video editing FAQs

What is the best AI video generator in 2025?

It depends on what you need. For end-to-end workflow — generation, editing, captions, collaboration, and publishing — Descript is the best choice because it's the only tool that combines all of those steps. If you only care about cinematic quality and are willing to edit elsewhere, Veo 3 is stunning. If you want advanced post-generation editing controls, Runway Gen-4 is the move. For fast social videos, InVideo wins on speed.

What is the best free AI video generator?

Descript offers a free plan with watermark and limited transcription, which gives you access to the full editing suite. Runway has a free tier with 125 credits. Luma Dream Machine's Lite plan at $9.99/month is affordable for experimentation. Most free plans have significant limits, so expect watermarks, lower resolution, or restricted minutes.

How do AI video generation models work?

AI video generation models are trained on massive datasets of video footage. They learn patterns about motion, lighting, physics, and visual coherence. When you give them a text prompt, they generate video by predicting what pixels should appear frame by frame based on what they learned during training. The best models (Veo, Sora, Runway) use diffusion techniques and transformer architectures to produce increasingly realistic results. They're impressive, but they're still prone to weird artifacts, especially with hands, text, and complex motion.

Which AI tool is best for marketers?

Descript. Marketers need to move fast, maintain brand consistency, and publish across multiple platforms. Descript lets you generate, edit, add captions, apply brand templates, repurpose content into short clips, collaborate with teams, and export in multiple formats without app-hopping. InVideo is a close second if you only need fast social videos and don't care about deep editing control.

Can AI tools replace traditional editing?

Not yet. AI video generators are great at creating drafts, visualizing concepts, and speeding up production. But they can't replace the judgment, taste, and storytelling instincts that make editing an actual craft. They can handle the tedious parts — cutting filler words, generating captions, finding highlight moments. But the creative decisions? Still on you. The good news is that AI video editing tools for creators can handle a lot of the grunt work, which frees you up to focus on the parts that actually matter.
