मैंने एक लंबी SRT फ़ाइल अपलोड की और कुछ ही सेकंड में पूरा अनुवाद तैयार हो गया। सबसे अच्छी बात यह रही कि टाइमिंग बिल्कुल वैसी ही रही, मुझे कुछ भी ठीक नहीं करना पड़ा।

我每周都要给视频加字幕，以前真的很费时间。RelaySub 直接在浏览器里就能翻译，速度很快，导出的文件也很干净，省了我不少功夫。

書き出す前に翻訳された一行ずつを自分で直せるのが本当に助かります。タイムコードがずれないので、安心して仕事に使えています。

خیلی ساده و سریع است. فایل را می‌اندازی، زبان را انتخاب می‌کنی و چند ثانیه بعد ترجمه آماده است. دیگر لازم نیست هیچ برنامه‌ای روی سیستم نصب کنم.

I've tried a bunch of subtitle tools over the years and this is the one I keep coming back to. It just works, and the file it gives me is always ready to upload.
