MP3 to video: the file you already have, ready for YouTube and social
Drop in the .mp3 you already have and ngram transcribes it, plans a scene for each topic, and renders a captioned branded MP4 instead of a waveform behind a single still.

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
Export 16:9, 1:1, and 9:16 in one render. Push to a /watch/ link, send it to YouTube or LinkedIn, or open it in the timeline editor for a final pass.
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.
Three ratios per render
16:9 for YouTube, 1:1 for the LinkedIn feed, 9:16 for Reels and Shorts, all smart-reframed from one storyboard so a single MP3 covers every channel.
A music bed under the voice
The agent picks a licensed background track from the library that matches the tone and pacing of your recording, sitting under the spoken audio.
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 moreMulti-format Export
Smart-reframe the same MP3-driven storyboard to 16:9 YouTube, 1:1 LinkedIn, and 9:16 Shorts in a single render, no re-cutting per platform.
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.

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.
The broader version of this page. Same pipeline, but it accepts WAV, M4A, AAC, and FLAC alongside MP3 when your recording isn't an .mp3.
Open converterThe reverse trip. Pull a clean MP3 or WAV out of a business video for a podcast feed, a transcript, or a translation pass.
Open converterClosest cousin when your MP3 is a long recording. Audio in, 8 to 12 standalone short-form clips out, captions and brand applied.

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 toolAI Voice Generator
No recording yet? Generate the spoken audio from a script with the brand voice, then feed it into the same MP3-to-video path.
Open toolEditing the rendered video

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.
