nPlay

nPlay

nPlay is a desktop video player built around subtitles. A video opens on its own preparation screen and plays once its subtitles are ready: nPlay finds or writes them, translates them and lines them up with the speech, each step shown with its progress. It looks for subtitles in the file itself, in files beside it, in its own saved copies and on the subtitle sites you connect, cheapest first. Subtitles from another release are lined up with where people actually speak, including the stretch between 25 and 23.976 frames a second, and subtitles that belong to a different film are refused rather than "fixed". Translation into about 80 languages, Sinhala and Tamil included, runs on your computer with an open model you download once, so nothing you watch leaves it, and both languages can be shown at once. When a film has no subtitles anywhere, nPlay writes them from its speech, also on your computer. Click any word for its meaning and save it to My words.

Anyone who watches films and series in a language they are still learning, or wants subtitles in their own language — Sinhala and Tamil included.

What you need

• Windows 10 or 11 (64-bit), macOS 13.3 or newer on an Apple Silicon Mac (M1 or later), or 64-bit Linux with GTK 3 and libmpv
• On Windows, the free Microsoft Edge WebView2 Runtime (already in Windows 11) for the sign-in; on Linux, WebKitGTK (Debian and Ubuntu: sudo apt install libwebkit2gtk-4.1-0)
• On Windows and Linux, a processor with AVX2 (Intel from 2013 on, every AMD Ryzen)
• 8 GB of memory recommended for translating and writing subtitles
• Disk space for the models you choose: from 60 MB (the smallest speech model) to about 2 GB (the translation model)
• Internet to sign in, to check a monthly or yearly plan on its payment day, to download models and to search the subtitle sites — playing, translating and writing subtitles work offline
• Your own free account or key for each subtitle site you want to use (optional)

What it does

Setting it up

1. Download

   Pick the download for your computer above. Each one is the whole player, with its three engines inside.

2. Unpack and start

   Windows: unzip and start nplay.exe. Mac: unzip and drag nPlay to Applications. Linux: unpack and run ./nplay. The note under each download says what the first start asks.

3. Sign in

   The Nugezza ID sign-in is the first thing you see: sign in or create your account. Your 30 free days start by themselves, with everything. No card is needed.

4. Download the models

   Open Models, let nPlay test your computer, and press Download: it fetches the speech, voice and translation models that suit it, each one checked before it is used.

5. Connect subtitle sites (optional)

   In Accounts, add your own free OpenSubtitles, SubDL, SubSource or Jimaku key. Gestdown needs none.

6. Keep it

   Choose a plan on this page whenever you like, and nPlay carries on by itself.

Licensing

A free 30-day trial, then 2.99 euro a month, 19.99 euro a year, or 39.99 euro once to keep it for good. A monthly or yearly plan works until its next payment, offline too. On that day nPlay needs the internet to check the payment, then carries on by itself until the next one. Bought once, it works offline for good. One licence covers one computer. You can cancel a subscription at any time. To move your licence to a new computer, ask us in the chat. Versions before 0.3 keep working as they are. nPlay is made only from open-source parts — Flutter, mpv, whisper.cpp, llama.cpp and Tesseract — and every model it downloads has an open licence.
