To get these subtitles working with your media player, follow these steps:

The version of Radioactive typically has a consistent frame rate (23.976 fps). If you try to use subtitles meant for a "BluRay" or "DVD" rip, they may drift out of sync over time because those sources sometimes have different runtimes or opening logos.

Rename the .srt (subtitle) file to match your video file exactly (e.g., Radioactive.2019.mp4 and Radioactive.2019.srt ). Same Folder: Keep both files in the same directory.
