Choose one clear thought
For your trial, choose a clip of ten seconds or less with one speaker and an audible voice. A short introduction or a single instruction is a useful place to start. Dubverta checks the actual media duration; a longer file is never silently trimmed.
Listen before you upload
Background noise, music over speech and overlapping voices make recognition harder. Listen once at normal volume. If you struggle to understand a phrase, an automated transcript may struggle too.
Keep your source close
Use a video you own or have permission to process. Your source stays private to your account. The current checkpoint is English; other languages have not been validated for this pilot.
Leave the final word to yourself
Read the transcript against the original video. Names, numbers and technical terms deserve a second look. Save your corrections as a new revision, then download your subtitles.
