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.

关于 Checksub

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.

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
