Captions vs Opus Clip (2026): Which Should You Use?
Captions and Opus Clip are both AI video tools aimed at creators, but they solve different problems. Captions is a full AI video studio for creating and editing content, complete with automatic subtitles, AI avatars and generative editing. Opus Clip is a repurposing engine that ingests long-form video, such as podcasts or webinars, and automatically produces short, captioned, social-ready clips.
The one-line answer: Pick Captions if you want to create and edit short videos (including AI avatar content) from scratch; pick Opus Clip if you already have long videos and want them chopped into shorts automatically.

What each tool actually does
The core distinction is creation versus repurposing. Captions is designed to produce and polish videos: it adds accurate animated subtitles in 100+ languages, offers AI editing styles, generates B-roll, music and sound effects, and can create AI actors through features like Mirage Studio, AI Creator and AI Twin (custom digital twins of yourself). It is a fit for creators who want to make talking-head or fully generated videos without filming much, or without filming at all.
Opus Clip works the other way around. You feed it a long recording, and its AI identifies the most engaging moments, cuts them into vertical shorts, adds animated captions with keyword and emoji highlighting, auto-reframes to portrait, and even scores clips for viral potential. It is built for podcasters, YouTubers and marketers who produce long content and need a steady stream of shorts without manual editing.
Pricing and limits
Captions offers a free $0 plan, then Pro at $9.99/month (captions, editing and watermark-free exports), Max at $24.99/month (adds generative features powered by 500 monthly credits), and higher Scale tiers reported at $69.99, $139.99 and $279.99 per month with progressively larger credit allowances, plus an Enterprise option. Generative features consume credits per use, and unused credits roll over up to 3x the monthly allowance. This structure means the entry Pro plan is cheap for captioning and basic editing, while the AI-generation features live on Max and above.
Opus Clip uses a credit system where 1 credit equals 1 minute of source video processed. Its Free plan gives 60 credits per month but adds a watermark, blocks editing, and expires clips after 3 days. Starter at $15/month removes the watermark and raises you to 150 credits (about 2.5 hours of source video), Pro at $29/month provides 300 credits per month (with annual billing reported around $174/year), and a quote-based Business tier adds priority processing, API access and more. Note that Opus Clip credits are consumed by input length, not output length, so processing long videos uses credits quickly.
Ease of use and workflow
Both tools are approachable, but they suit different habits. Captions is an editing and creation environment: you work shot by shot, apply styles, and generate avatar or B-roll content, which rewards creators who want hands-on control over the finished video. Opus Clip is closer to automation; upload once, and it returns a batch of ready-to-post clips with minimal input, which is ideal when volume and speed matter more than fine-grained control. Opus Clip does allow editing of its output on paid plans, but its strength is the hands-off first pass.
Best use cases
Captions is best for solo creators, marketers and educators who want to produce short-form or avatar-led videos from scratch, add professional captions, and generate supporting media without a full editing suite. Opus Clip is best for anyone sitting on a library of long recordings, such as podcasters, streamers, coaches and webinar hosts, who want to consistently mine that footage for shorts across TikTok, Reels and Shorts.
The verdict
Choose Captions if you need to create and edit videos, add multilingual captions, or generate AI avatar content, and you want a low entry price with generative features available as you scale.
Choose Opus Clip if you already record long-form content and want an automated way to turn it into captioned, reframed short clips, with pricing tied to how much source video you process. Many creators use both: Opus Clip to harvest clips, Captions to caption and enhance original videos.
