Answers
Frequently asked questions
- How do I add an AI voice to a video?
- Open Add AI Voice in oVideo, upload the video, type or paste the script and pick one of 96 ElevenLabs voices. Choose where the voice starts and whether the original sound is lowered or muted, then generate. You get an MP4 up to 1080p with the voice mixed in, and optional captions timed to the voice.
- Can I add AI voice over to a video I already recorded?
- Yes, that is exactly what this tool is for. Upload a video you recorded (MP4, MOV or WebM, up to 10 minutes and 1 GB) and oVideo puts the AI voice on it. The original sound drops to 15% while the voice speaks, or is muted if you prefer.
- How much does it cost?
- Standard (ElevenLabs v4 Turbo) costs 30 credits per minute of voice and Premium (ElevenLabs v4) 50, billed per started 30 seconds: a 20 second voice is 15 credits on Standard, a 2 minute voice is 60. Captions add 5, 10 or 20 credits by length. Starter costs $10 a month for 400 credits.
- Is there a free AI voice over for video?
- Not for this tool. Add AI Voice needs a paid plan, from Starter at $10 a month. Free accounts can still try 3 subtitle videos, 2 AI images and 3 split screen videos where the free plan is available.
- What is the difference between Standard and Premium?
- Standard uses ElevenLabs v4 Turbo: clear and quick, good for tutorials and product videos. Premium uses ElevenLabs v4, ElevenLabs' most natural model, with more emotion and natural pauses, good for ads and stories. The same 96 voices work with both.
- Which languages can the voice speak?
- The 96 voices are English, Spanish, German, French, Turkish, Russian and Arabic voices, and the voice reads the script in the language you write it in. To add captions in another language instead, Translate Subtitles covers 28 languages.
- What happens if my script is longer than the video?
- The page estimates the voice length as you type and warns you when it runs past the video. If the voice is longer, the last frame is held until it ends, so no word is cut. A script far longer than the video is blocked before you pay.
- Can I clone my own voice or upload an audio file?
- No. The voices come from oVideo's list of 96 ElevenLabs voices. Voice cloning, recording your own voice and uploading an audio file are not available.
- Can I use the video commercially?
- oVideo's Terms of Service allow commercial use of the videos you create, including monetized channels and client work; read the Terms for the exact conditions.
