DubDuck vs Vidby

DubDuck is a web service for translating and dubbing video dialogue. It transcribes and translates speech, clones speakers’ voices, and lip-syncs dubbed video into 40+ languages. Its editor provides dialogue and translation workspaces, speaker controls, a frame-accurate timeline, and segment-level re-dubbing. The documented workflow covers upload, source and target language selection, transcription and editing, calibration, dubbing, preview, and export. New accounts start with $10 in free credits, while videos dubbed before payment show a visible DubDuck.com watermark. Beta documentation limits uploads to 3.5 minutes and 50 MB, although the homepage describes uploads as any format and length. Dubbing costs $1.95 / min per minute of dubbed dialogue, billed by the second; only dialogue is charged, and calibration is billed the same way during the first dub. Top-ups cost $5.00 per once, $10.00 per once, or $25.00 per once. Credits do not expire while the account remains active. Voice characteristics are used for the project and discarded shortly after rendering.

Vidby is web-based software for translating videos and documents, creating subtitles, and dubbing content.

The Free plan costs nothing and includes 30 credits, 70 languages, a watermark, and original and subtitle downloads. Basic costs $9.95 a month; the listed higher tiers are Starter at $35 a month and Pro at $75 a month. Credits apply only to Full AI video orders and unused credits expire at the end of the monthly period. Document translation accepts DOC, DOCX, PPT, PPTX, XLS, XLSX, and PDF files; after Free plan credits are used, it costs USD 0.25 per page.
