Convert Video to Text with AI Transcription

How Video Transcription Works

When you upload a video file, Exactum extracts the audio track and processes it through an enterprise-grade neural speech engine trusted by major media companies. The AI converts speech to text with word-level timestamps, allowing you to click any word and jump to that exact moment in the video. The extraction step handles any container format automatically, so you never need to pre-process your files.

Speaker diarization automatically identifies different voices in your video — perfect for interviews, panel discussions, podcasts, and meetings. Each speaker is labeled so you can follow who said what throughout the recording. The diarization model adapts to the number of speakers in real time, whether your video features two people or a large roundtable.

After transcription, the AI analysis layer generates three levels of summaries (short, medium, and detailed with 1,000-1,500 words), extracts 5-8 key points, creates 4-8 timestamped chapters, performs sentiment analysis, identifies topics and themes, and can even fact-check claims made in the video. All of this runs automatically, delivering a complete content brief alongside your raw transcript.

Creating Subtitles from Video

One of the most popular uses of video transcription is generating subtitle files. Exactum exports transcripts as SRT (SubRip Subtitle) and VTT (Web Video Text Tracks) files, which are the industry standards for video subtitles and closed captions. The timing precision is word-level, so captions align tightly with the spoken audio.

SRT files work with YouTube, Vimeo, Facebook, Instagram, LinkedIn, and virtually every video editing tool including Premiere Pro, Final Cut Pro, and DaVinci Resolve. VTT files are used for HTML5 web video players. Both formats include precise timestamps so subtitles appear in sync with the spoken words. You can download the files and upload them directly to any platform without manual adjustment.

Adding subtitles to your videos improves accessibility for deaf and hard-of-hearing viewers, boosts engagement (85% of Facebook videos are watched without sound), and helps with SEO since search engines can index subtitle text. Organizations subject to accessibility regulations such as ADA or WCAG can use Exactum to meet compliance requirements efficiently.

Subtitle and Caption Generation

Generating accurate subtitles manually is time-consuming — a skilled captioner spends four to eight hours per hour of video. Exactum automates the entire process, producing broadcast-quality SRT and VTT files in minutes. The AI segments speech into readable caption blocks of 8-10 words, keeping each line under 42 characters for comfortable on-screen reading.

Multi-language subtitle workflows are straightforward. Transcribe the video once, then translate the transcript into any of 80+ languages. Export each translation as a separate SRT file to create multi-language caption tracks for your video. This is invaluable for creators distributing content internationally or organizations with multilingual audiences.

Caption files generated by Exactum include proper line breaks, timing offsets, and sequence numbering that conform to the SRT and VTT specifications. You can import them directly into YouTube Studio, Vimeo, social media schedulers, or professional editing suites without post-processing. For burned-in captions, editors can use the SRT file as a reference layer in Premiere Pro or DaVinci Resolve.

Subtitle accuracy matters for viewer retention. Studies show that videos with captions see higher watch times and better engagement metrics. Exactum ensures your captions are accurate, properly timed, and formatted to industry standards so viewers stay engaged throughout.

Video Content Repurposing

A single video contains enough material for dozens of written content pieces. Exactum's repurposing engine transforms video transcripts into blog posts, social media threads, email newsletters, show notes, press releases, and more using 27 built-in templates. Each template is optimized for its target format, adjusting tone, length, and structure automatically.

Content marketers use video repurposing to maximize ROI from webinars, product demos, and interview recordings. Instead of spending hours rewriting, you select a template and receive polished output in seconds. The AI preserves the key messages and supporting details from the original video while adapting the language for the new medium.

Podcasters and YouTube creators benefit especially from repurposing. A 30-minute episode can generate a 1,500-word blog post, a Twitter thread highlighting five key takeaways, a LinkedIn article with professional framing, and a newsletter summary — all from the same transcript. This multiplied content output drives audience growth across channels without additional recording effort.

For teams, the combination of transcription and repurposing creates a scalable content pipeline. Record once, transcribe with AI, and distribute across every channel your audience uses. Integrate with Zapier or the Exactum API to automate the entire workflow from upload to publication.
