## 概览

Checksub 是一套以字幕为核心构建的视频本地化平台。上传视频后，服务会自动转录语音、生成与原语言同步的字幕，并允许你用数十种预设重新设定样式或添加动画，其中包括一键卡拉 OK 效果。以此为基础，它可以把整段脚本翻译成 200 多种语言，并针对字幕的阅读节奏调整行长度与断句，而不是直接套用通用机器翻译。

除字幕之外，Checksub 也处理 AI 配音：它会把原始人声与音乐、环境噪音分离，再用逼真的 AI 声音重新生成对白，同时保留其余的音频氛围。声音克隆功能可以让你在约 30 种语言中用克隆的本人声音进行替换，而

## 定价与套餐

Checksub offers a free trial that includes credits covering roughly one hour of video and access to every feature. 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.

## 关键功能与能力

- **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.

## 主要用例

- **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.

## 优势

- 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

## 局限

- 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

## 常见问题

### 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.
