Video is the most demanding medium to produce, which is exactly why AI video tools have attracted so much attention. Some generate entirely new footage from a text prompt. Others take the drudgery out of editing, captioning and translating. The second group, less flashy, is where most creators get everyday value.
Updated September 2026: we removed OpenAI’s Sora, which has been discontinued, and added sources on AI video with sound and on YouTube’s disclosure rules.
Text-to-video generation
Models such as Google’s Veo, Runway, Kling, Luma and others can generate short video clips from text prompts or images. The quality has advanced rapidly, with more realistic motion, lighting and, in some models, synchronized sound: Google says its Veo 3.1 models generate native audio, from conversations to sound effects. The market also changes fast in the other direction. OpenAI shut down the Sora app in April 2026 and its API in September 2026, a reminder not to build a workflow around a single generator.
Good for: concept visualization, b-roll, social content, storyboards and creative experiments.
Limitations: clips are short, consistency of characters and objects across shots is still difficult, physics can break down, precise control is limited and generation can be costly on paid plans.
AI-assisted editing
This is where the practical gains are largest:
- Text-based editing. Tools like Descript let you edit video by editing its transcript: delete a sentence, and the footage is cut.
- Automatic captions in apps such as CapCut, Premiere Pro and many social platforms.
- Filler word and silence removal.
- Auto-reframing for vertical and square formats.
- Highlight clipping, which suggests short clips from long videos.
- Audio cleanup that reduces background noise and echo.
Translation and dubbing
AI dubbing can translate speech into other languages, sometimes in a voice resembling the original speaker, and adjust lip movements. This can open content to new audiences, but always have a fluent speaker review the result.
AI avatars
Services like Synthesia and HeyGen create videos with AI presenters from a script, popular for training and internal communications. They are efficient for updating content quickly, though audiences may find them less engaging than real people.
Consent and honesty Never clone someone’s voice or likeness without their explicit permission. Label realistic AI-generated video where platforms or context require it. YouTube, for example, has required creators since March 2024 to disclose realistic content made with altered or synthetic media. Our deepfakes guide explains why this matters.
Choosing tools
- Start with editing features built into software you already use.
- Match the tool to the output: a talking-head tutorial needs different tools from a product ad.
- Check commercial usage rights for generated footage, voices and music.
- Watch credit-based pricing, since generation costs add up quickly.
- Review everything before publishing, especially captions and translations.
Where AI video pays off today
AI video generation is impressive and improving fast, but for most creators the biggest wins today are in editing, captioning and repurposing. Use generation where it genuinely helps, keep humans in the loop and respect consent. For still images, see our photo editing guide.
