DubDuck vs VideoLingo

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.

VideoLingo uses AI to produce bilingual subtitles and dubbed video. Its documented subtitle workflow applies NLP and LLM segmentation, context-aware translation, then a process of translation, reflection, and paraphrasing. Qwen3-ASR and Qwen3-ForcedAligner provide word-level subtitle timing. Users can supply a YouTube video or upload local video and audio files. Listed dubbing options include edge-tts, OpenAI TTS, SiliconFlow FishTTS, and GPT-SoVITS. The Free plan accepts English and Chinese videos, processes 15 minutes, and outputs 480p with a watermark. Starter costs $5 a month and provides 60 minutes of processing, eight input languages, and 1080p output. Pro costs $30 a month and includes 360 minutes, Fish Audio voice cloning, voice separation enhancement, and Open API access; an active Pro account receives an API key. VideoLingo is available on the web and supports Windows, macOS, and Linux, with source installation and Docker deployment described. Uploaded videos and subtitles are deleted after 30 days. The privacy policy says there are no cookies or tracking, and names Cloudflare and Together AI as service providers.
