Streaming services automatically provide subtitles, but their quality isn't always guaranteed. At the same time, there's a classic problem for those who prefer offline playback: subtitles can lose synchronization. The simplest shortcut is to look for alternatives with better timing, but if you need to advance subtitles or sync their content by just a few milliseconds, one of these tools might be helpful.
Synchronizing Subs: Art and Patience
If translating dialogues in a series or movie is already a titanic task on its own, generating and setting the correct timestamps to synchronize subtitles is a real nightmare. When a subtitle is out of sync, you notice it almost immediately, and it destroys the experience from start to finish. The first recommendation in those cases will always be to look for an alternative subtitle, and we have previously shared some of the best sites to download Spanish subtitles.
However, sometimes we don't have that luxury. If there is only one subtitle on the web and it is completely out of sync, we have to work with it whether we like it or not. The good news is that there are several free tools to advance subtitles, delay subtitles, perform advanced editing of their timestamps, or apply small adjustments "on the fly" to get out of trouble.
How to Advance Subtitles, Synchronize Dialogues, and Not Lose Your Mind
SubShifter
The most positive aspect of synchronizing subtitles with SubShifter is that you don't need to download anything. The entire process is reduced to loading the subtitle in .SRT format (the only compatible format) in the Shift section, setting the desired offset, and clicking Resync!. For example: If the subtitles are three seconds ahead of the movie, the resync is with a positive symbol (+3.0). Otherwise, if they arrive three seconds late, the offset is negative (-3.0). The linear correction section is more complex, and not entirely recommended. For advanced edits, we have something better.
Subtitle Edit
Subtitle Edit is the nuclear option. At the time, we dedicated a full article to it, and the general instructions there remain perfectly valid. The visual synchronizer stands out as its most robust feature, as it provides precise control over subtitles, with steps of 100 milliseconds. On the other hand, you can use Subtitle Edit to translate subtitles, automatically repair common errors, or convert subtitles from one format to another.
MPC-HC
What if I don't want to edit anything? In that case, don't worry: The main media players on the market have on-the-fly resync functions to advance or delay subtitles. In Media Player Classic Home Cinema it's called "Subresync", and you activate it with Ctrl+6. Choose the line to synchronize, locate the video at the correct place, and press F5 or choose the Current option from the context menu. You might need more than one adjustment during playback, but it's preferable to re-syncing everything.
VLC Player
On the VLC Player side, once you have opened the video and the subtitle file, go to the Tools menu and click on Track Synchronization. This player uses the same menu to advance or delay subtitles, and to adjust audio.
In Summary
Advance subtitles, edit their content, translate dialogues, repair format errors, convert formats, or simply apply small adjustments during playback. No matter what you want to do, one of these tools will help. Don't hesitate to try them, and good luck!
