How to Make Short Videos With AI in 2026

July 2026 · 8 min read

Short-form video dominates social media in 2026. TikTok, YouTube Shorts, and Instagram Reels reward consistent posting — but making videos from scratch every day burns out even the most dedicated creators. AI tools now handle the heavy lifting: writing scripts, generating B-roll footage, adding captions, and even voicing over narration. Here's the full AI-powered short video workflow, step by step.

1. Generate Video Ideas and Scripts With ChatGPT

Open ChatGPT or Claude and describe your niche. A prompt like "Give me 20 short video ideas about productivity hacks for remote workers, each with a hook that grabs attention in the first 3 seconds" produces a goldmine of topics. Pick an idea, then ask: "Write a 60-second script for this idea in a fast-paced, conversational tone. Include visual cues in brackets." The AI delivers a ready-to-use script with timing suggestions and visual direction — no blank-page paralysis.

2. Generate B-Roll and Visuals With AI Image and Video Tools

Not everyone has a camera-ready setup, and stock footage fees add up fast. AI image generators like Midjourney and DALL-E create custom visuals from text prompts — product shots, scene illustrations, infographic backgrounds. For motion, tools like Runway and Pika generate short video clips from text descriptions. Even if you film yourself talking, AI-generated B-roll fills gaps and makes videos visually engaging.

3. Add AI Voiceover Narration

Not comfortable recording your own voice? ElevenLabs and Play.ht produce voiceovers that are nearly indistinguishable from human speech. Paste your script, pick a voice from the library, and generate professional narration in seconds. Adjust speed, tone, and emotion to match your content style. For faceless channels — which are huge in 2026 — AI voiceover combined with AI visuals creates complete videos without ever appearing on camera.

4. Auto-Captions and Editing With CapCut

CapCut is the go-to editor for short-form content, and its AI features save hours. Upload your clips and voiceover, then use auto-captions to generate accurate subtitles with one click — essential since most viewers watch without sound. CapCut's AI also trims silences, removes filler words, and suggests trending templates and effects. The free version covers virtually everything a short-form creator needs. Export directly to TikTok or Reels format.

5. Optimize Titles and Hashtags for Discovery

A great video with poor packaging gets ignored. Feed your video topic to ChatGPT and ask: "Write 5 attention-grabbing titles for a short video about [topic], each under 80 characters, with relevant hashtags." The AI generates platform-optimized copy that boosts click-through rates. Pair this with an eye-catching thumbnail — Canva's AI background remover and text overlays make thumbnail creation fast — and your content is ready for prime time.
