Can VLC Automatically Generate Subtitles?
If you are searching for “Kan VLC automatisch ondertitels genereren“, the core question you most want to know is actually just one: Does VLC have the ability to automatically generate subtitles? **
Here is a direct, authoritative and professional answer for you.
a. Can VLC generate subtitles automatically?
The conclusion is very clear: VLC cannot generate subtitles automatically. The reason is simple: VLC does not have ASR (Automatic Speech Recognition) technology. This means that VLC cannot automatically understand the sounds in the video or convert them into text. It can only handle subtitle files that you have prepared in advance.
b. Why do many users think that VLC can automatically generate subtitles?
Because VLC supports loading external subtitles. Users can manually load subtitle files such as .srt En .vtt. So many people mistakenly think that VLC “can generate subtitles automatically”, but in fact, it only “can load subtitles automatically”. This misunderstanding is very common. Especially when users see that VLC prompts “automatically search for subtitles”. But this function only grabs existing subtitles from the online subtitle library, rather than generating them by listening to the audio automatically.
c. What Can VLC Do? (But Not Generate Subtitles)
Although VLC cannot generate subtitles automatically, it is still very powerful in terms of subtitle playback functionality:
- Show subtitles Load an external subtitle file and display it.
- Synchronized subtitles You can manually adjust the subtitle timing to match the video.
- Switch subtitle track If there are multiple language subtitle tracks, you can switch freely.
- Modify Style Change the playback style such as font, size, position, color, etc.
All of these are “playback functions”. However, VLC has no “subtitle creation function” at all.
How to Use VLSub to Search and Add Subtitles in VLC
Although many users are looking forward to VLC offering a complete AI automatic subtitle generation feature, as of the latest update, VLC still lacks the ability of automatic speech recognition. This means it cannot “understand” the video content on its own and generate subtitles. Therefore, we still have to resort to the traditional method – using the VLSub extension plugin.
The following is the standard usage process of VLSub. The steps are short and clear, suitable for beginners and also meeting the needs of advanced users.
Step 1: Confirm that the VLSub extension is installed
Most VLC players come with VLSub by default. You can check it in the menu: “View” → “VLSub”. If you don’t see it, you can install it manually from the VLC plugin center.
Step 2: Open the video that needs subtitles added
After playing the target video, load the VLSub extension. Only in this way can the plugin correctly read the video file information and match the subtitles.
Step 3: Start VLSub
Click: View → VLSub and the plugin interface will pop up.
Step 4: Select Search Method
Step 5: Select Subtitle Language
Bijvoorbeeld:
Engels
Chinese
Spaans
Frans
Or any other language you need.
VLSub will filter the results based on the selected language.
Step 6: Click "Search" to start the search.
VLSub will automatically connect to the OpenSubtitles database. After a few seconds, you will see a list of multiple subtitle files, including:
Subtitle language
Release version
The possibility of matching video versions
Step 7: Select the subtitles and click "Download"
After the download is complete, VLC will automatically load and display the subtitles. You don’t need to add them manually, which is very convenient.
Step 8: If the subtitles are not synchronized, you can manually fine-tune them
VLC supports quick adjustment:
H key: Delay subtitles
G key: Advance subtitles
J key: Switch subtitle track
This makes the subtitle playback more accurate.

Q2. How do I generate subtitles automatically for VLC?
VLC itself cannot generate subtitles automatically. You need to use a third-party tool to generate the subtitles and then import them into VLC. Common practices include:
- Use online tools such as Easysub to automatically generate subtitles, and then download the SRT file.
- Use Whisper to generate subtitle files locally.
- Use YouTube’s automatic subtitles, and then export them.
Then, in VLC, select: Subtitle → Add Subtitle File to load it.
Q3. Does VLC support SRT and VTT formats?
Support. VLC supports the major subtitle formats, including:
- SRT (Most commonly used)
- VTT (Commonly used in web videos)
- ASS/SSA (With styled animations) – SUB / IDX
The loading method is very simple and the compatibility is stable.
Q4. Why is my VLC subtitle out of sync?
Common reasons include:
- The frame rate of the video does not match the subtitle file.
- There is a discrepancy in the subtitle production timeline.
- The source of the subtitles is incorrect (same name but different version).
- The video was re-encoded, resulting in a change in the time.
Solution: In VLC, click on: Tools → Track Synchronization and then fine-tune the “Subtitle Delay”. Usually, a few seconds of fine-tuning will solve the problem.
Q5. Which auto subtitle generator is most accurate for VLC?
Depending on the user’s requirements:
Fluisteren: It has the highest accuracy rate, but the operation is the most complicated.
