WAV to Video: turn a lossless track into captioned video for teams
Paste the transcript or words from your WAV session and ngram builds the video around it: a generated voiceover, a scene per topic, captions, and your brand kit, not a flat waveform pinned over one image. Dropping the .wav file in directly is coming soon.

How it works
Four steps from the words in your WAV to a watchable video.
No DAW re-open, no rendering a waveform clip in a video editor. Paste the transcript from your WAV session, accept the storyboard, ship a captioned branded video. Uploading the .wav file itself is coming soon.
Paste the transcript
Drop in the transcript or the words from your WAV session, a master voice-over, a podcast cut, or any spoken track. Already have the transcript from your DAW or a transcription tool? Paste it straight in as the script.
ngram reads the script
The agent splits the script into topic sections and pulls the quotable lines, then pairs it with a generated voiceover so the words become a narrated track without re-recording the session.
ngram plans the visuals
Each section gets its own scene: AI imagery, motion text, B-roll, or a speaker card. The brand kit stamps logo, fonts, and color on every frame, so the words from the WAV stop being audio-only.
Render and publish
Export an MP4 in 16:9, 1:1, and 9:16 from one render. Push it to a /watch/ link, post the cut to your channel, or open it in the timeline editor for a tighter pass.
Output controls
Smart defaults for studio WAV. Real knobs when you need them.
Transcript-driven scenes
Every scene binds to a range of the WAV. Trim the script and the visuals follow, so a 26-minute session stays in sync without dragging a single audio clip on a timeline.
Burned-in branded captions
A lossless voice track transcribes cleanly, so captions land accurate the first pass. They sit on every export by default, styled by the brand kit, and export to .srt or toggle off per render.
Scene art per segment
AI imagery, lower-thirds, and pull-quote cards swap as the topic shifts in the WAV. The single-image-behind-a-waveform look every other WAV converter ships is the one thing ngram skips.
Three ratios per render
16:9 for the long cut, 1:1 for the feed, 9:16 for vertical, smart-reframed from one storyboard. No re-rendering the WAV three times to hit three placements.
A bed under a spoken WAV
When the WAV is a voice session, the agent layers a licensed background track that matches the pacing. When it is already music, the track plays as-is and the visuals move to it.
Clip out the highlights
Pull a quotable 30 to 90 second range out of the WAV and export it as a standalone vertical clip, same brand, same scenes, sized for short-form.
Translate the voiceover
Regenerate the spoken track from the WAV in any ElevenLabs-supported language, with translated captions and on-screen text re-rendered to match.
Security and data handling
Your uploaded WAV and the renders stay in your workspace. Talk to sales about security, access controls, and data handling for your team.
The rest of ngram
The WAV upload is the front door. These run the rest of the pipeline.
Script Generation
Once the WAV is transcribed, the agent tightens the spoken track into a publishable script with a hook, body, and closing CTA, so a raw session export reads like it was written for video.
Learn moreAI Visuals
A WAV has no picture, so ngram generates scene-matched imagery from the transcript. Each topic in the track gets a distinct visual instead of the same waveform graphic looping for the whole runtime.
Learn moreCaptions
Lossless WAV audio transcribes with high accuracy, so the burned-in branded captions are clean from the first render, the key value when the video plays muted in a feed.
Learn moreBrand Kit
Logo, fonts, colors, intro and outro applied to every scene built from the WAV, so a podcast master and a launch voice session come out looking like the same brand.
Learn moreMulti-format Export
Smart-reframe the same WAV-driven storyboard to 16:9, 1:1, and 9:16 in a single render, instead of bouncing the audio to a new video file for each placement.
Learn moreTranslation
Translate the transcript pulled from the WAV, regenerate the voiceover, and re-render captions, turning one English session into localized video for every key market.

Coming from a different source? There's a converter for that.
WAV to video runs the same transcribe-then-storyboard pipeline as the rest of the audio family, just tuned for an uncompressed, often very large source file. Swap the input, keep the brand kit and render stack.
The broad audio entry point. If your source is a podcast clip, webinar audio, or any mixed format other than a raw WAV, start here and the same scene-planning pipeline takes over.
Open converterThe compressed cousin of this page. When the file you have is a lightweight .mp3 rather than a heavy lossless WAV, route through here for the identical scene-matched output.
Open converterThe reverse trip. Pull a clean WAV or MP3 back out of a finished video for a transcript, a podcast feed, or a translation pass.

Polishing the source WAV

Background Noise from Audio
A WAV preserves every detail, including the room tone and HVAC hum. Strip them out first so the transcript and the rendered voiceover both stay clean.
Open toolAudio to Text
Run the WAV through AssemblyAI on its own when you want the transcript first, then drop it back into the converter as the script for the video.
Open toolAI Voice Dubber
Re-voice a non-English WAV recording into English (or the other direction) before you convert the lossless track into a branded video for a new market.
Open toolAI Voice Generator
No recording yet? Generate the spoken audio in the brand voice from a script, then feed that into the WAV to video pipeline as the source track.
Open toolEditing the rendered video

Video Editor
Open the video built from your WAV on a real timeline: trim scenes, shift captions, and swap visuals before you publish.
Open toolVideo Cutter
Trim by transcript, not timecode. Pick the strongest 60 seconds of the WAV and export it as a standalone short.
Open toolAdd Subtitles to Video
Burn or export .srt subtitles in any language for the WAV-driven render before it heads to a muted-autoplay feed or an international audience.
Open toolAdd Music to Video
Swap the background bed under a spoken WAV. Pick a different mood from the library or upload a licensed track of your own.

If you don't have a WAV yet
Text to Speech Video
No session bounce? Type the script and ngram generates the voiceover and the video together, the same pipeline a WAV upload feeds downstream.
Open toolAI Avatar Video Generator
Pair a generated voiceover with an avatar host so the result feels like a hosted segment instead of the faceless narration a bare WAV produces.
Open toolVideo Script Generator
Draft the spoken script before you record, so the WAV you bounce already has structure and a CTA built in.
Open toolText to Video
Skip recording entirely. Type the talking points and let ngram script, voice, and visualize, with the same look a WAV upload produces.
