Vocnu for product and training videos
Upload a product demo, an onboarding clip or a training video and get it back with a voice-over and subtitles in another language. A two-minute demo in five languages costs €0.66 to €1.00 in Standard quality, or €1.32 to €2.00 in Premium. Our 22-second test clip on 10 November 2026 took 2 credits and came back as an MP4 with the voice-over, the original sound and subtitles in both languages.
Uploads run in the web app in your browser, with nothing to install.
How short clips are billed
Product videos are short, and Vocnu rounds each video's minutes up, so the seconds matter:
| Clip | Billed as | Credits in Premium |
|---|---|---|
| 22 seconds, our test on 10 November 2026 | 1 minute | 2 |
| 1 minute 1 second | 2 minutes | 4 |
Trim the silence at the end of a clip that runs just over a minute. Our 22-second clip went into Spanish and came back as an MP4 of 22.3 seconds, as long as the upload, with the Spanish voice-over as its main audio, the English original as a second track and subtitle tracks in both languages. With it came the voice-over audio on its own as M4A, the Spanish subtitles as SRT, VTT and ASS files, and the English transcript.
Subtitles for feeds that play without sound
Videos in social feeds often start muted. For a platform that shows no subtitle files, burn the subtitles into the picture for 1 more credit a minute: they are always visible and cannot be turned off. Where the platform takes an SRT or VTT file, upload that instead, so viewers can turn it off.
| Quality | A two-minute demo in five languages | With burned-in subtitles |
|---|---|---|
| Premium | €1.32 to €2.00 | €1.98 to €3.00 |
| Standard | €0.66 to €1.00 | €1.32 to €2.00 |
| Economy | €0.33 to €0.50 | €0.99 to €1.50 |
The prices run from the largest credit pack to the smallest. SDH subtitles, which also write out sounds and speaker names, add 1 credit a minute.
Screen recordings where nobody talks
If nobody speaks in a video, the app tells you before you start, and Vocnu voices the text on screen instead, word for word in its own language or translated. That suits a silent walkthrough with captions in the picture. We have not tried it on a product video yet, so start with a short one.
Training videos for teams
- Standard is enough for most internal training: clear voices and a good translation for half of Premium's credits.
- If the trainer's voice under the translation distracts, turn the original sound off; the file then holds the voice and silence between its lines.
- Before you translate a series, send one video's share link to a colleague who speaks the language. Anyone with the link can play it and download its files without an account, until you turn the link off or the files expire.
- Vocnu deletes uploads after 7 days and finished files after 30, so keep the results in your own system.
When Vocnu is not the right pick
- Your product's screens and slides are full of text that must read in the new language. Vocnu changes the sound and adds subtitles; the text in the picture stays as it was.
- A presenter on camera should keep their own voice, a cloned brand voice or matching lips. Vocnu does none of these; see Rask AI and ElevenLabs.
- Several people talk and each needs a voice of their own. One voice reads every speaker.
- The wording must be approved, as in safety or compliance training. Have a person translate it: Vocnu has no editor for fixing lines before they are voiced.
