How do I convert audio to video?
Upload your audio file and ZinAIStudio does the rest automatically: it transcribes the speech, matches every sentence to relevant stock footage, burns in timed subtitles, and exports a finished MP4 with your original audio on top — no video editor needed.
What is an audio to video converter?
An audio to video converter turns a sound-only file like MP3 or WAV into a video file (MP4) that platforms like YouTube, Instagram, and TikTok can actually play, since none of them accept audio-only uploads. ZinAIStudio goes further than a basic wrapper — it adds matching stock footage and burned-in subtitles instead of a static image.
Welche Audioformate werden unterstützt?
MP3-, WAV- und M4A-Dateien werden unterstützt. Die maximale Dateigröße beträgt 50 MB.
Does converting audio to video reduce audio quality?
No. Your original audio track is preserved and layered onto the final MP4 without extra lossy re-encoding, so there is no audible quality loss — the same voice recording, just wrapped in a video file with visuals and subtitles.
Wie genau ist die Transkription?
Accuracy is typically 90%+ for clear English audio. You can edit the transcript before generating the video.
How much stock footage is available?
We pull from a library of over 3 million free, commercially-licensed clips.
Kann ich das Video nach der Erstellung noch bearbeiten?
Ja. Nach der Erstellung können Sie einzelne Szenenclips austauschen, neu rendern und das aktualisierte Video herunterladen.
Can I post the video on YouTube, Instagram, or TikTok?
Yes. The exported MP4 has no watermark and all stock footage is licensed for commercial use, so you can publish it on any platform or use it in ads.
Ist es wirklich kostenlos?
Ja — erstellen Sie ein Konto und generieren Sie Videos kostenlos.
