Subtitles don’t sync in VLC? Here’s what you need to do
It happens sometimes that you download subtitles separately then plug them in in VLC and BOOM, it doesn’t sync correctly with the video. The first thought that often comes into mind is that: You need to download another subtitles file. But that’s not true. In VLC Media Player, you can actually speed up/slow down the subtitles so they run in tow with the video being played.
How to Speed Up Subtitles in VLC
If the subtitles are behind the video, you need to speed them up. To do that, press H on your keyboard while on the video screen. Tapping on the G button once will speed up the subtitles by 50ms hence the message “Subtitle Delay -50 ms.”
In-case the subtitles still lags behind, continue pressing the G key until they are in sync.
How to Slow Down Subtitles in VLC
Another circumstance is when the subtitles are ahead of the video. This happens when you see the subtitles first then the audio comes out later. In order to slow down the subtitles, press the H button while on the video screen and your video is playing. You will know it worked by seeing a “Subtitle Delay 50 ms” message somewhere on the bottom right of the video.
Doing that once will slow down the subtitles by 50ms(milliseconds). Continue to tap on it until it’s in sync. In our tests, we had to repeatedly do that a couple of times before the video and subtitles were in sync, but that depends. Every scenario is unique in its own way.
