Features of audio to video
Universal audio file format support
The free audio-to-video converter supports MP3, WAV, M4A, FLAC, AAC, OGG, AIFF, and most audio formats. JPG, PNG, GIF, and BMP work as thumbnail layers. The built-in engine checks compatibility and locks timing on a canvas the full length of your track.
AI Avatar narrators for your podcast
Pair your audio file with an Avatar V presenter that lip-syncs to every word. Pick a stock avatar or clone your own from a 15-second clip. Your podcast or voice-over becomes a face-forward video viewers will engage with.
Script-driven visual animation
Already have a script paired with the audio? Run it through the text to video tool and the AI builds matching scenes, B-roll, custom motion graphics, and animation. Output a finished video ready for YouTube, LinkedIn, or your LMS in one pass.
Animated captions and subtitles
Captions turn audio-only content into engaging, high-quality video for sound-off social media feeds. The subtitle generatortranscribes every word, styles it on-brand, and keeps captions synced to your audio. Burn captions in or export an SRT file to easily share elsewhere.
Multilingual audio conversion 175+
Translate the same audio into 175+ languages with native voice cloning and lip-synced delivery. One podcast, one recording, one announcement reaches global audiences in hours. No re-takes, no second voice actor, no scheduling a separate edit pass per market.
Use cases
Long podcasts sit in an audio feed and never travel beyond loyal listeners. Convert each episode into a polished video, add captions and an avatar of the host, then clip highlights for YouTube, Reels, and TikTok in minutes.
Music needs a visual home to stream on socials and platforms. Select a static image, AI-generated visuals, or branded animated backdrop. The result is a music video or voiceover clip ready for any output format and platform.
Voice recordings and team sessions waste time as raw audio. Convert them into structured training videos using a text-to-speech generator backup voice, captions, and an on-brand presenter. Advantive cut content creation time 50%.
Your audio probably exists in one language. Translate it into 175+ with AI lip sync, keep the host's tone, and ship localized versions in one afternoon. Reach audiences your current podcast can't touch.
Audiobook samples and course intros need video format support to convert audio listeners into viewers. Drop in audio files, generate visuals or an avatar narrator, and turn each chapter teaser into a shareable AI video explainer.
Quick voice memos from execs or product managers stay buried in Slack threads. Convert your audio into video with captions, slide visuals, and brand colors, then refine in the AI video editor. Polished updates ship the same day.
How it works
Turn any audio file into video in four steps. Upload the file, shape the visuals, generate the output, and download.
Drop in an MP3, WAV, M4A, FLAC, or AAC file. The platform reads the timing and length automatically.
Choose a static image, an AI-generated background, an avatar narrator, or a branded template.
The AI builds a scene track, syncs captions, and lip-syncs any avatar to your audio.
Preview the video, adjust any element, and export it as a high-resolution MP4 ready for any platform.
It pairs an audio file with a visual layer and exports a playable video file. You pick a static image, an avatar, or AI-generated visuals to match the sound, then download an MP4 you can share anywhere.
Both. Pick a single static image for a quick MP3 to MP4 conversion, or let AI generate matching B-roll, motion graphics, and an avatar narrator. The audio file drives the timing for either option.
Upload your MP3, select a visual style, and the platform locks the visuals to the audio timeline. For talking content, add an avatar that lip-syncs the words using the video script generator. Download the MP4 video file in one click.
The tool supports MP3, WAV, M4A, FLAC, AAC, OGG, and most common audio formats. Output covers MP4, MOV, AVI, and other video formats, sized for the platform you select: square for Instagram, vertical for TikTok and Reels, 16:9 for YouTube and LMS.
