understanding subtitles

hello
i need subtitles ffor a star trek movie, being as i dont speak kingon or vulcan.....I found ones that display english all the time, what i need is subtitles that only display when non english is spoken....is there an easy way to find these

thanks

If the original movie did not put a translation on screen for the alien speech, then you're not supposed to know what they're saying or you're supposed to get it based on context.

but the srt shows english subtitles plus klingon and vulcan....so its all there just want a forced subtitle as far as i know

Often, when that's the case, you then see the alien speech text on screen twice. But if that's not happening, I guess the alien translation was not baked into the original film, but was overlayed (easy enough with digital projection but not something I would expect with film). Anyhow, it seems you already know to look for the keyword "forced". Did you already check the tracks in the video using something like VLC?

Thought I saw a reply mentioning winmerge, possibly to edit the srt for my needs, maybe the post was deleted

You'll need to edit the subtitle file manually to only include the desired lines. Players of course don't know what lines are in what language, so can't filter them out manually. Other than finding an appropriate subtitle, you'll need to do it yourself.

Open the .srt file with notepad and edit out the extra lines you don't want. The srt format is simple enough for notepad to understand and it's easy to grasp the basics of it. There are also dedicated editors for the task if you want something more complex.
