Match the release name to your video file. The French files here cover releases such as The.Superdeep.2020.MULTi.1080p.HDLight.x264.AC3-EXTREME.French, Superdeep.2021.1080p.AMZN.WEB-DL.DDP2.0.H.264-EVO, Superdeep (Kolskaya sverhglubokaya / Кольская сверхглубокая). If none matches exactly, choose the one with the same source (WEB-DL, BluRay, HDTV) and resolution — those usually share the same timing.
Download the .srt and put it next to the video file with the same name, and most players load it automatically. In VLC use Subtitle - Add Subtitle File, in Plex and Jellyfin upload it from the item's subtitle menu, and in Stremio pick it from the subtitle button during playback.
A constant offset means the subtitle was timed to a different release: shift it with G and H in VLC, or J and K in MPV, until the first line matches. If the drift grows through the film, the frame rate differs and a file from the same release group is the better fix.
