Captions to Video for campaign copy that already has a voice
Start with the caption lines or on-screen copy your team has already approved. Build the supporting visuals, voice, and pacing around them, then keep the full project ready for new formats and audiences.

How it works
Four steps from a caption file to a video you'd actually publish.
No timeline scrubbing, no manual scene-by-scene cutting, no pasting subtitles into a slide builder. The caption text you already have becomes the script, and the script becomes a storyboard you can edit before anything renders.
Paste the caption body or drop a file URL
Paste an SRT or VTT block straight from your editor, or link to a hosted caption file. ngram strips the timestamps and cue numbers, keeps the spoken lines, and stitches fragmented cues back into full sentences.
Caption lines become a paced video script
ngram reads the cue text as a running narration, finds the hook, the body, and the close, and groups adjacent lines into scenes instead of one slide per subtitle. Your wording survives where it carries the message.
Review the storyboard before render
Each scene shows the caption lines it covers, the visual direction, and the duration. Merge two cues into one beat, drop a filler line, or rewrite a hook in plain language, and the script and scene plan re-flow together.
Export with captions burned in
Review the captioned video for its intended channel, including the crop and caption placement, then export one MP4 from Studio. Prepare and review another aspect ratio as a separate edit.
Output controls
Smart defaults from the caption text. Real knobs when you need them.
Reads SRT and VTT bodies
Paste the raw file body and ngram parses the cue index, the timestamp range, and the text. Numbered cues, blank-line separators, and WebVTT headers are handled; plain caption lines with no timing convert too.
Cue-line-to-scene mapping
Short cues that belong to one thought get merged into a single scene; a long monologue cue gets split across beats. You see exactly which caption lines map to which scene in the storyboard before render.
Script-first review
Read the full narration assembled from your captions before any visual generates. Cut a line, fix a typo a hand-typed caption left behind, or tighten the open. Each edit re-paces the scenes downstream.
AI Visuals per caption beat
Each scene gets a brand-matched image or short generative clip tied to what that caption line actually says. No keyword-matched stock footage that turns a captioned explainer generic.
Voiceover that reads the captions
A default ngram voice, your cloned founder voice, or a multilingual ElevenLabs voice reads the caption text aloud. The spoken track and the on-screen captions stay in sync line for line.
Caption styling from your Brand Kit
Logo, fonts, colors, motion, intro, and outro pulled from your saved Brand Kit. The burned-in captions use your brand's caption preset, so the 50th captions-to-video looks as on-brand as the first.
Re-render in another language
Translate the caption-driven script and re-burn the captions in the target language without rebuilding the storyboard. One caption source ships a localized cut per market.
Prepare each channel edit separately
Set the intended channel and aspect ratio for the captioned video, then review the crop, caption placement, and CTA before exporting one MP4. Prepare another channel version as a separate edit.
The rest of ngram
What ngram does to a caption file that a subtitle tool doesn't.
Captions
Your source captions are re-styled to your Brand Kit and burned back into every export, so muted feeds still read the same lines you pasted in. The caption text drives the video and rides on top of it.
Learn moreScript Generation
Reads your caption cues and assembles them into a hook-body-CTA narration. Not a slide-per-subtitle echo, but a paced script you'd recognize as the same lines, restitched for video.
Learn moreAI Visuals
Each scene of the captions-to-video gets a brand-matched image or generative clip tied to that cue's meaning. The visuals follow what the caption line says, not a stock-clip keyword table.
Learn moreAI Voiceover
Narrate the caption lines in an ElevenLabs voice, your cloned voice, or a supported language. The voiceover reads the exact cue text you approved in the storyboard, kept in step with the burned-in captions.
Learn moreBrand Kit
Logo, fonts, colors, motion, intro and outro applied to every scene built from your captions. The same kit drives the caption preset, so every future captions-to-video stays on-brand at scale.
Learn moreConvert the finished caption-led video
Finish the caption-led video in Studio and download one MP4. When a site, player, or handoff requires MOV, WebM, or MKV, convert that file separately in Video Converter, one input and one output per job.

Source is a file, a transcript, or plain text? Pick the converter that matches the input.
Captions to video is one node on ngram's script-and-storyboard pipeline. Every text-source converter here shares the same scene planner, Brand Kit, and review step. Choose the aspect ratio for the current edit, then prepare other channel versions separately.
When your captions are a clean .srt file. ngram parses the numbered cues and timestamp ranges, then runs the same line-to-scene flow you use here for any caption block.
Open converterWhen the source is a full transcript instead of timed caption cues. Same scene planner, with extra parsing for speaker turns and long unbroken paragraphs.
Open converterWhen you have raw script or copy with no caption timing at all. Paste any chunk of writing and the same engine turns it into a storyboarded branded video.

How it compares
If you've been using something else to go from captions to video.
VEED, Kapwing, and Pictory all start from a finished video and add or restyle captions on top of it. ngram works the other way: the caption text is the input. It reads each cue as a beat, plans a storyboard you can argue with before render, generates the visuals per scene, and burns the captions back in on the way out.
