1. determine if it’s a timescale difference, or a simple “timing” offsync. (here we talk about the more problematic timescale difference)
2. sync 1st line in SRT, to the video’s first line, save this new SRT as “VIDEONAME.srt”, take note of the time (FIRSTTIME)
3. find the last line in the SRT file, take note of the time. (LASTSRTTIME)
4. find the last line in the VIDEO, take note of the time as well. (LASTVIDEOTIME)
5. head to: https://subshifter.bitsnbites.eu/
6. use Linear correction
7. choose the “VIDEONAME.srt”
8. Time #1 = FIRSTTIME –> FIRSTTIME
9. Time #2 = LASTSRTTIME –> LASTVIDEOTIME
10. Hit Resync! that’s it!
