OpenClip adds word-level AI captions to your videos with 10 visual presets — and simultaneously creates Shorts-ready clips from your long-form content. content-creation starter ## Scenario YouTube creators and video marketers know that captions significantly increase average view duration, make content accessible to deaf and hard-of-hearing viewers, and are essential for the 85% of social video watched on mute. Manually writing or cleaning up auto-generated captions is time-consuming and often inaccurate. OpenClip automates the entire captioning process with word-level precision — while also detecting your best moments and producing vertical Shorts-ready clips in the same workflow, maximizing the return on every video you upload. ## Workflow 1 ### Upload your YouTube video Upload your long-form YouTube video file to OpenClip. This can be a finished video ready for captioning, a raw recording, or an existing YouTube export — any standard video format is accepted. 2 ### AI generates word-level captions OpenClip automatically transcribes your video and syncs captions to every individual spoken word — not just sentence-level chunks. This produces natural, accurate captions that track exactly with speech rhythm. 3 ### Choose a visual caption preset Select from 10 professionally designed caption presets — Default, Dan, Dan Reveal, Pop, Mozi, Kendrick, Sara, Lucy, Tayo, or Beast. Each preset includes its own typography, highlighting style, color scheme, and optional emoji injection. 4 ### AI detects your best moments for Shorts Simultaneously, OpenClip's AI moment detection identifies the 5-15 most clip-worthy segments from your video — giving you a full set of captioned YouTube Shorts candidates from the same upload. 5 ### Export captioned video and Shorts Download your full captioned video in and export all detected clips in 9:16 vertical format for YouTube Shorts — with captions already burned in and speakers dynamically framed. ## Benefits Word-level caption sync is more accurate and natural than sentence-level tools 10 visual presets let you match captions to your channel's brand identity Captions burned directly into exports — no separate subtitle file management Accessibility compliance for deaf and hard-of-hearing audiences Captures the 85% of viewers watching video on mute Same upload produces captioned long-form video AND YouTube Shorts candidates ## Key Metrics 10 Caption presets available Word-level Caption sync precision 5-15 per video Shorts clips generated Up to 40% Watch time improvement ## Features ### Word-Level Caption Sync Captions are synced to every individual spoken word — not sentence blocks — for natural, accurate timing that keeps viewers reading along in real time. ### 10 Visual Caption Presets Choose from Default, Dan, Pop, Mozi, Kendrick, Beast, and more — each with distinct typography, highlight colors, and emoji injection options to match your channel brand. ### AI Moment Detection for Shorts While captioning your video, OpenClip simultaneously identifies your best 5-15 clip moments — giving you a full YouTube Shorts content pipeline from one upload. ### Speaker Tracking for Shorts When your clips are cropped to 9:16 for YouTube Shorts, AI speaker tracking keeps the active speaker dynamically centered in every frame. ### Accessibility Compliance Burned-in captions ensure your content is accessible to deaf and hard-of-hearing audiences and fully viewable by the 85% of viewers watching on mute. ### Vertical Short-Form Export Export your captioned video in and get all Shorts in 9:16 vertical format — all with captions rendered directly into the video file. ## Frequently Asked Questions ### How accurate are OpenClip's AI-generated captions? OpenClip uses high-accuracy speech recognition to generate word-level captions. Accuracy is generally very high for clear spoken-word content in standard English. Accuracy can vary with strong accents, heavy background noise, or highly technical jargon — in those cases, you may want to review the transcript before finalizing. ### Are captions burned into the video or provided as a separate subtitle file? Captions are burned directly into the exported video file as part of the selected visual preset. This ensures they display correctly on every platform — including YouTube Shorts, TikTok, and Instagram — without relying on platform subtitle support. ### Can I customize the caption style to match my YouTube channel branding? Yes. OpenClip offers 10 caption presets — Default, Dan, Dan Reveal, Pop, Mozi, Kendrick, Sara, Lucy, Tayo, and Beast — each with distinct visual styles. These cover a range of aesthetics from clean and minimal to bold and high-energy, with options for word highlighting and emoji injection. ### Does adding captions also give me YouTube Shorts from the same video? Yes. When you upload a video to OpenClip for captioning, the AI simultaneously runs its viral moment detection on your transcript. You receive your captioned full-length video plus a set of ranked Shorts candidates — all with captions and speaker tracking — from the same upload. ### Do captions help with YouTube SEO? YouTube's algorithm indexes the auto-generated captions it creates from your video's audio. Having clean, accurate spoken content helps its indexing. The visual captions OpenClip adds are burned into the video file and don't directly affect YouTube's text indexing — but they significantly improve watch time and viewer retention, which are strong ranking signals. ### Is OpenClip good for creators who upload long videos like tutorials or vlogs? Absolutely. Long tutorial videos and vlogs are exactly the kind of content that benefits most from OpenClip — you get captioned versions of the full video for accessibility and watch time, plus a batch of Shorts automatically extracted for channel growth and cross-platform promotion. ### What plan do I need to add captions to my YouTube videos? The Starter plan is sufficient for creators who upload occasionally and need captioning plus Shorts extraction. If you publish frequently or want to process multiple videos in bulk, the Pro plan is recommended for its higher processing volume and batch capabilities. ### Can OpenClip handle videos with multiple speakers for captioning? Yes. OpenClip's speaker diarization identifies different speakers in the transcript, and the word-level captions track whoever is speaking at any given moment. Speaker tracking for visual framing also handles multiple on-screen speakers when generating Shorts clips. ## Give Every YouTube Video the Captions It Deserves Upload your video to OpenClip and get word-level AI captions, a branded visual preset, and a full set of YouTube Shorts — all from one upload.
