Generate Sup Manually

You can use Subtitle Edit to convert BDN(xml+png) to Blu-ray Sup(.sup).

1. Tools - Batch convert..., then drag the .xml to input listbox.

2. Check Save in source file folder, and then change Format to Blu-ray sup.

3. IMPORTANT!! Open Settings dialog, set correct Video res and Frame rate, otherwise Subtitle Edit will output 24fps and 1080p by default. And set Bottom margin and Left/right margin to 0

Thanks
