Question

Hello, everyone!

I played the lecture videos with .mp4 extension, but the subtitles didn’t work. The subtitles with .srt extension are included in the course materials by MIT OCW.

Then, I tried to edit the .srt file with SubRip, SubtitleEdit, which all failed.

Who can tell me how to use the subtitle file in the media player, so that the subtitle can display while the video (mp4 format) is playing?

By the way, I use VLC of VideoLan multimedia player.

Looking forward to your reply.

Thanks a lot!

Sorry, I've answered this, one minute before
Click on the Bump button was a mistake
Here's the answer
I think, The problem is that the correct syntax of a ".srt" file format is something like this:
"
Subtitle number
hours:minutes:seconds,milliseconds --> hours:minutes:seconds,milliseconds
Text of subtitle (one or more lines)
Blank line
"
and MIT OCW srt files does not have the milliseconds part.
So, to solve the problem, download notepad++ app, then open all of your MIT OCW srt files.
Go to Search menu, then select Replace, in the search mode, select "Regular expression".
Then, in Find box, put "(..:..:..)" (without quotations)
and in Replace box, put "\1,000" (for sure without quotations)
and push "Replace All in All Opened Documents".
Wait a few minutes...
You can use "Save All" button, up there.

Tada, You have your subtitles are fixed now
