Ongoing use is on paid subscription plans; exact tiers and per-minute limits are shown on the Checksub pricing page, and larger teams can book a demo for custom quotes. ## 關鍵功能與能力 - **Automatic subtitling and animation:** Generates accurate captions with AI, then lets you apply dozens of style presets and animations, including one-click karaoke effects, before exporting burned-in video or subtitle files. - **Translation into 200+ languages:** Machine translation built specifically for subtitles, so line lengths and timing stay readable instead of copying a generic document translator. - **AI dubbing with voice isolation:** Separates music and background noise from the original voices, then replaces only the speech with realistic AI dubbing so the audio atmosphere is preserved. - **Voice cloning in 30 languages:** Clone a speaker's voice from a sample and use it to replace the original voice-over across dozens of languages with a natural delivery. - **Advanced online editor:** Edit, re-time and regenerate any subtitle line or dubbed sentence directly in the browser, with script-to-subtitle alignment for pre-written content. ## 主要使用情境 - **Localize internal training videos (Training and L&D teams):** Produce one master training video and translate it into 200 languages for global staff instead of shooting a separate version per market. - **Boost reach with styled captions (Social media managers):** Add animated, on-brand subtitles to short-form clips so viewers keep watching with the sound off, then publish to each channel from the same workspace. - **Run multi-language channels (YouTubers and creators):** Dub and subtitle existing videos into other languages to grow audience, watch time and search visibility without recording new content. - **Speed up client deliverables (Agencies and localization vendors):** Handle bulk subtitle, translation and dubbing jobs in one editor and hand clients polished burned-in files or SRT/VTT captions. ## 優勢 - Subtitle, translation, dubbing and voice cloning live in one workspace - Purpose-built subtitle translation keeps line lengths readable - Voice isolation preserves music and ambient audio in dubs - Free trial credits cover about an hour of video, enough to test real workflows ## 限制 - Credits are consumed per language created, which adds up for multi-market projects - The free trial is short-lived and paid plans are subscription-based - The editor has many options, so new users need some time to learn the interface ## 常見問題 ### How does the Checksub free trial work? The trial gives you free credits covering roughly one hour of video. While credits remain you can test every feature, including translation, subtitles and AI dubbing. ### How does Checksub translate a video? It first transcribes and captions the audio in the original language, then translates that transcription. Finally it can generate a natural, synchronized replica of the speaking voices for dubbing. ### Why must subtitles be created from the audio first? Captions in the original language are needed before any automatic translation, because translating directly from audio produces lower quality. For that reason credits are debited for each language created. ### Can I export an editable subtitle file instead of burned-in video? Yes. Checksub can burn styled subtitles into the exported video, or you can export a subtitle file to use in another editing or publishing tool. ### Checksub 的每月流量與成長趨勢為何？ Checksub 目前每月有 10.35萬次造訪，月流量變化為 -3.55萬（成長率 -25.6%）。其主要來源市場為新加坡（佔比 9.9%），其中包含每月 5.44萬次直接造訪與每月 — 次自然搜尋造訪。 ### Checksub 是免費的嗎？其定價模式為何？ Checksub 採用免費試用、付費定價模式。Checksub offers a free trial that includes credits covering roughly one hour of video and access to every feature.
