Common Questions

How good are the subtitles?

Very good for dialogue and conversation. The translation model is specifically trained on Mandarin→English and produces natural, readable text. It handles casual speech, slang, and context well. It won't catch every poetic nuance a human translator would, but it's easily good enough to follow along and enjoy.

How long does processing take?

With a GPU (10GB+ VRAM): ~8-15 minutes for a 2-hour video. CPU only: ~45-90 minutes depending on your hardware. You can queue multiple videos and walk away.

Is it really 100% offline?

Yes. After the one-time setup (downloading AI models), everything runs locally. You can disconnect your internet and it works exactly the same. Zero network calls during processing.

What if it doesn't work for me?

30-day money-back guarantee, no questions asked. Email support@chinesesubs.app and you'll get a full refund.

What are the system requirements?

Minimum: Windows or Linux, 10 GB free RAM, 15 GB free disk space, Python 3.8+.
Recommended: GPU with 10GB+ free VRAM — NVIDIA, AMD, or Intel (for much faster processing).

Why not just find fan-subs?

Most Chinese content outside mainstream C-dramas never gets subtitled. Variety shows, indie dramas, YouTube creators, live events — none of it. ChineseSubs generates subtitles for any Chinese video, on demand — no searching forums, no dead links, no waiting for someone else to translate it.

What if my computer is slow?

It'll still work — just takes longer. On CPU-only, expect about 45-90 minutes per 2-hour video. Queue your videos, let it run in the background, and come back later. A GPU with 10GB+ VRAM speeds things up 3-5x.

What types of Chinese content does it work with?

Any Chinese video — C-dramas, variety shows, movies, Bilibili content, YouTube videos, live streams, interviews, cooking shows, and more. If it has Mandarin audio, ChineseSubs can subtitle it.
