Last Updated on December 30, 2020 by Leo Standy

A friend of my wife introduced “parasite” to her and gave it a lot of praise which interested us. We did some search and found that it is a great movie with good artistic quality. People said “A film that always has two thoughts in its head at once, a spectacular epic and tightly wound chamber piece, chicly sophisticated, brutal as a hammer.” about it.

We could not wait to watch this movie so I searched online and downloaded a Blu-way version in MKV and put it in my portable hard drive. Unfortunately, these are no English subtitle embedded. So I found one English subtitle in .srt for parasite and open it with VLC and add this third-party subtitle. And the subtitle got a 10 second delay. MAN!

At this moment, I think I have to a tool in this chaos. If you are suffering from similar problems, please keep reading this article, I will show you how to add subtitle to MKV and adjust the subtitle timing if you need it.

The first thing you need to do is to get the exact time span between the subtitle and the movie. To get the precise time, You can open the time counter on your phone and tap the record button at the point of the voice occur and the text display.

Then, open subtitle-sync-shifter and upload your subtitle file, srt, ass, ssa, smi, and webvtt are support. Then enter the offset time into the text field with label Shift (in milliseconds). If the audio is before the subtitle text, then enter the time in negative. If the audio is after the subtitle text, then enter the time in positive. Please note that 1 second = 1000 milliseconds. Click Shift button and you will be redirected to a page with ads, be patient, you will get a button to download the synced subtitle file.
