Case study to video: the customer-story cut buyers actually watch
Upload a case study PDF and ngram reads the document, pulls the strongest quote and the results, drafts the script, builds the storyboard, and renders a branded customer-story video with voiceover and captions.

How it works
Four steps from a written case study to a customer-story video.
No shoot, no agency, no six-week production cycle. Upload the case study, approve the storyboard, render the MP4.
Drop the case study in
Upload the case study PDF, paste the published page link, or paste the text. We parse the layout and pull the customer name, the challenge, the solution, the results, and any pull-quotes off the page.
We write the story script
The agent shapes the case study into a story arc: the customer's problem, the turning point, the outcome, and the headline metric. It leads with the strongest quote and closes on a CTA.
Tune the storyboard
Every scene is visible before render. Swap a stat callout, shorten the narration, change the voice, or ask in chat for a sales-enablement cut versus a website-hero cut from the same case study.
Render and ship
Export 16:9 for the website, 1:1 for the feed, 9:16 for vertical. MP4, GIF, or WebM, plus a hosted /watch page, embed code, or direct download for the sales team.
Output controls
What you control between the case study and the final cut.
Quote-first story extraction
ngram reads the case study and surfaces the strongest customer quote, the before-state, and the headline result. The narration is built around that arc instead of reading the document top to bottom.
Script you edit in plain English
The generated story script appears scene-by-scene before any render. Trim a sentence, swap which metric leads, or paste an exact quote the customer approved. Pacing and captions update with the words.
Results as animated stat cards
The percentages, dollar figures, and time-saved numbers in the case study become animated stat callouts and lower-thirds, so the proof lands on screen instead of sitting in a paragraph.
Brand kit on every scene
Logo, colors, fonts, and your intro and outro are stamped on every scene. Each customer-story video comes out matching the rest of your marketing, not a stock template.
Voiceover from a library or your clone
Narrate with an ElevenLabs or MiniMax voice, or a cloned voice from /app/settings/voice. The voiceover is spoken narration generated from the script; it regenerates automatically when you change the words.
Burned-in captions, brand-styled
Captions are generated from the same script the voiceover reads, so they match exactly. Font and position follow the brand kit. Leave them on for muted feeds where most case study videos get watched.
16:9, 1:1, and 9:16 from one render
The storyboard reframes per aspect ratio. Ship a website-hero cut, a square for the feed, and a vertical for social from a single case study upload, with the same approved story.
Localized customer stories
Translate the script and regenerate the voiceover in another language via ElevenLabs. Useful when the same customer win needs to land with prospects in a different region.

Script Generation
Turns the case study into a story script: the customer's challenge, the turning point, the result, and a CTA. It leads with the strongest quote instead of summarizing the document in order.
Learn moreAI Voiceover
Narrates the story script in a brand-appropriate voice. Swap voices, clone a founder or CSM voice, or regenerate the same customer story in a second language for a regional prospect.
Learn moreMotion Graphics
Animates the proof from the case study. The headline ROI number, the time-saved stat, and the customer quote become animated callouts and lower-thirds instead of static lines of body copy.
Learn moreAI Visuals
Fills the gap when a case study is text-only. Generates branded backgrounds and B-roll so a written customer story becomes a watchable scene, not six slides of bullet points.
Learn moreCaptions
Burned-in captions generated from the script, exact to the narration. Essential for customer-story videos that autoplay muted in a LinkedIn feed or a sales email.
Learn moreBrand Kit
Applies your logo, colors, fonts, and intro/outro to every video built from a case study, so a whole library of customer stories renders in one consistent brand voice.

What teams ship after they convert the case study.
A written case study becomes a customer-story video
The case study PDF already has the quote, the challenge, and the numbers. ngram pulls them into a tight customer-story video with the headline result animated, ready for the website and the deal room.
See use caseTurn the case study quote into a testimonial cut
Lead with the customer's strongest line, layer in the result, and close on the logo. A short testimonial video carries proof in a prospecting email better than a five-page PDF attachment.
See use caseCase study videos reps can drop into a deal
Convert each customer case study into a branded video leave-behind. Send it after a discovery call or embed it in a proposal so the buyer watches the win instead of opening another document.
See use caseProof in the first line of a cold email
A 30-second case study video showing a similar customer's result earns more replies than a paragraph claiming it. Match the prospect's industry to the right customer story and lead with it.
See use caseCustomer wins as LinkedIn-native video
A written case study barely gets clicked on LinkedIn. ngram turns the headline result into a captioned vertical with a branded intro and a CTA back to the full case study for the gated download.
See use caseStock the brand library with customer proof
Run the whole case study back catalog through the converter and end up with a library of on-brand customer-story videos for the website, ad placements, and the next launch campaign.
See use caseCustomer proof inside an investor update
A standout customer case study becomes a 60-second segment in a board or investor update, with the retention and revenue numbers pulled straight from the document and animated on screen.
See use caseSwitch stories that show the before and after
A case study about a customer who moved off a competitor becomes a comparison-flavored video: the old pain, the switch, and the result, framed for prospects evaluating the same alternatives.

Got the source in a different format?
Case study is one of many converters that share the same script, storyboard, voiceover, and brand-kit pipeline. Same engine, different document going in.
If your case study lives in a deck, one-pager, or whitepaper PDF, this sibling runs the same page-aware extraction. Closest match when the source is any document, not just a customer story.
Open converterWhen the proof is a results report or a customer-impact study rather than a narrative case study, this converter is tuned for data-led documents and turns the findings into animated callouts.
Open converterIf the case study is still a working Google Doc or Word file, this sibling reads the outline directly so you can ship the video before the PDF version is even finalized.

Editing the video further
After the case study has become a draft cut
Video Editor
Open the case-study video on a real timeline. Re-order the proof beats, trim the intro, or cut a 15-second teaser and a 90-second full story from the same customer source.
Open toolAdd Subtitles to Video
Burn in or export .srt captions matching the story script. Frame-accurate and brand-styled, so the customer quote stays readable when the video autoplays muted.
Open toolVideo Cutter
Pull the single strongest moment out of the full customer-story render, the quote or the headline stat, by transcript rather than scrubbing a timeline. Drop it into a prospecting email.
Open toolAdd Music to Video
The agent picks a licensed library track that matches the pacing of the narration, so a case study video built on quiet voiceover gets the lift a customer story needs.
Open toolGenerating from scratch
If the case study is missing the visual half
AI Video Generator
When the case study is all text, the AI Video Generator drafts the establishing scenes the customer story never had, then drops them into the same storyboard as B-roll.
Open toolAI Avatar Video Generator
Pair the story script with a synthetic presenter when the customer can't be on camera. A consistent narrator introduces the win and frames the result between the proof scenes.
Open toolText to Speech Video
Skip the storyboard step for a quick cut. Paste a section of the case study, get spoken narration over branded scenes, ideal for a one-quote social clip.
Open toolVideo Script Generator
Want to shape the customer story as a script before rendering? The script generator returns the full hook, story beats, and CTA in plain text first.
Open toolPolishing the source

AI Image Generator
Generate the branded visuals a text-only case study is missing, like a clean customer-logo lockup or a result-themed background, before the conversion runs. Output flows into Image Lab.
Open toolAI Voice Generator
Audition narrator voices for the customer story before committing to a full render. Same TTS engine the conversion pipeline uses for the final voiceover.
Open toolVideo Translator
Translate the finished case study video into other languages with regenerated voiceover and translated on-screen text, so one customer win serves prospects in several regions.
Open toolVideo Caption Generator
Generate clean, brand-styled captions for the customer-story cut. The quote and the headline metric stay legible in feeds where the sound is off by default.
