MP3 to Video for audio your audience should be able to watch
Start with the recording where the voice or story already exists. Add relevant visuals, accurate captions, and brand, then adapt the project for YouTube, social, training, or internal communication.

How it works
Four steps from an audio file to a video that holds attention.
No timeline project, no exporting a single cover image, no manual scene-by-scene work. Upload the .mp3, approve the storyboard, ship the branded MP4.
Upload your .mp3
Drop the MP3 you already have, up to 500 MB. WAV, M4A, AAC, OGG, and FLAC work too, and you can paste a transcript if the recording lives somewhere else.
AssemblyAI transcribes the track
The spoken audio comes back as a timestamped transcript with topic shifts and quotable lines marked. That transcript becomes the script the storyboard hangs off.
ngram plans a scene per segment
The agent maps each section of the audio to its own scene, AI imagery, motion text, B-roll, or a speaker card, and stamps your brand kit on every frame and caption.
Render and publish
Review the MP3-based 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 for an audio file. Real controls when you want them.
Transcript-driven scenes
Every scene is pinned to a range of the MP3's transcript. Edit the script and the visuals follow, so you never drag clips on a timeline to keep audio and picture in sync.
Burned-in branded captions
Captions sit on every export by default, styled by the brand kit: font, weight, position, accent color. Switch to .srt or turn them off per render.
Scene art per topic
AI imagery, B-roll, lower-thirds, and pull-quote cards change when the audio moves to a new topic. The result reads as a video, not an mp3 parked behind one static image.
Prepare each channel edit separately
Set the intended channel and aspect ratio for the MP3-based video, then review the crop, caption placement, and CTA before exporting one MP4. Prepare another channel version as a separate edit.
A music bed under the voice
Choose a licensed background track from the library, set it under the spoken audio, and adjust its level before export.
Clip out the highlights
Pick a quotable 30 to 90 second chunk of the MP3 and export it as a standalone vertical clip with the same brand and captions.
Translate the voiceover
Regenerate the spoken track in any ElevenLabs-supported language and re-render the captions and on-screen text to match, turning one MP3 into video for several markets.
The rest of ngram
Converting the MP3 is step one. These run the rest of the pipeline.
AI Visuals
An MP3 has no picture, so the agent generates a distinct visual for each topic in the audio instead of leaving you with a flat cover image for the whole runtime.
Learn moreCaptions
Burned-in branded captions are frame-aligned to the original MP3 audio. They carry the message when the video plays muted in a YouTube or social feed.
Learn moreAI Voiceover
If you only have a script and no MP3 yet, ngram generates the spoken track first, then runs the same transcribe-and-storyboard path you'd use for an uploaded file.
Learn moreBrand Kit
Logo, fonts, colors, intro, and outro land on every scene, so a video built from a raw MP3 matches the rest of your channel rather than looking like a stock converter.
Learn moreConvert the finished MP3-driven video
The MP3-driven video leaves Studio as a single MP4. Use Video Converter afterward to make one MOV, WebM, or MKV file; it is a separate one-file, one-output step.
Learn moreTranslation
Translate the transcript, regenerate the voiceover, and re-render captions to turn one English MP3 into localized video for every market you sell into.
Learn moreUse cases
Where an MP3 turned into video earns its place.
Podcast episode MP3s into shareable clips
Take the .mp3 export from your podcast host and let ngram cut the strongest 60 to 90 second moments into captioned vertical videos for the feed.
See use caseTalk recordings into a branded recap
A 30-minute talk you only have as an MP3 becomes a tight visual recap with quote callouts and brand-aligned scenes, ready to share before the event wraps.
See use caseRecorded call audio into visual proof
Sync a customer voice memo or call MP3 to a branded scene with their company logo and ship a testimonial card without filming anyone.
See use caseOne webinar MP3, a month of marketing
Use one audio export as source material for a launch teaser, a long-form recap, or a social clip. Prepare and review each branded cut separately.
See use caseFounder voice notes into LinkedIn posts
Record a take on your phone, export the MP3, and ship a captioned LinkedIn video that reads like a post but earns the algorithm's video boost.
See use caseVoice memos into demand-gen posts
A sales lead drops an MP3 about a customer win and ngram returns a captioned, brand-colored social video before the standup ends.
See use caseRecorded SME audio into onboarding video
Subject-matter-expert interview MP3s and recorded SOP audio become structured onboarding videos with captions, callouts, and section dividers.
See use caseAudio newsletters into embeddable video
Turn the MP3 version of your newsletter into a captioned branded video readers watch in the inbox instead of opening a podcast app.
See use caseOther converters
Started somewhere other than an MP3? There's a converter for that.
Same transcribe-then-storyboard pipeline, different starting file. MP3 to video shares the brand kit, security model, and render stack with every other converter.
Tools that pair with this converter
Clean up the audio. Edit the video.
Polishing the source audio
Fix the MP3 before the storyboard runs
Background Noise from Audio
Strip room tone and hum from a phone-recorded or downloaded MP3 so the transcript reads clean and the rendered audio sits well under the visuals.
Open toolAudio to Text
Run the MP3 through AssemblyAI on its own when you want to review and edit the transcript first, then drop it back in as the script.
Open toolAI Voice Dubber
Re-voice a non-English MP3 into English, or the other direction, before you convert it into branded video for a new audience.
Open toolAudio to Video
Plan a captioned MP3 story from an approved show-notes or transcript-page URL and cover art. Direct audio upload is not available on that page yet.
Open toolEditing the rendered video
Take the rendered MP4 further
Video Editor
Open the MP3-to-video render on a real timeline to trim scenes, shift captions, and swap visuals before you publish.
Open toolVideo Cutter
Trim by transcript, not timecode. Pull the 60-second quote from the audio and export it as a standalone short.
Open toolAdd Subtitles to Video
Burn in or export .srt subtitles in any language for the MP4 before it heads to a muted-autoplay feed or an international audience.
Open toolAdd Music to Video
Swap the background bed sitting under the spoken track. Pick a different mood or upload a licensed track of your own.
Open toolGenerating from scratch
When you don't have an MP3 yet
Text to Speech Video
Type the script and ngram generates the voiceover and the video together, the same downstream pipeline an uploaded MP3 runs through.
Open toolAI Avatar Video Generator
Pair the generated voiceover with an avatar host so the result feels like a presented segment instead of faceless narration over an MP3.
Open toolVideo Script Generator
Draft the spoken script before you record, so the MP3 you hand to the converter already has a hook, a body, and a CTA.
Open toolText to Video
Skip recording altogether. Type the talking points and let ngram script, voice, and visualize, with the same look as an MP3-driven render.

How it compares
If you've been using a free converter to turn an MP3 into video.
Most online MP3-to-video converters drop a single still image or a waveform behind the audio and call it done. ngram reads the MP3, plans a scene for each topic, applies your brand, and renders the captioned video in one pass.
