Best way to translate subtitles?

If I have subtitles in .srt format in english and want to translate to spanish with help from ia, trying for the context of subtitles to remain the same (of course some will be lost given ia is not actually watching the movie, but hoping it will make better job than just a translator) what would be the most efficient way to go about it? I dont need a batch job, just translate a few .srt
