The beginning of this year witnessed a significant announcement at the Consumer Electronics Show (CES). VideoLAN, the organization behind the popular VLC media player, revealed an innovative feature leveraging AI technology for real-time, accurate video subtitle translation. The remarkable aspect of this feature is its offline capability; it functions entirely on the user's device, eliminating the need for an internet connection. This advancement represents a significant leap in simplifying the movie and series viewing experience, freeing users from the tedious search for appropriate subtitle files, especially for less common languages like Korean, Italian, Arabic, Spanish, etc., which might not be readily available. While VideoLAN hasn't disclosed the official release date, this article presents a practical alternative for enjoying a similar experience: creating automatic, real-time Korean, Spanish, English, etc. subtitles for movies and videos using AI and the exceptional PotPlayer media player.
While VideoLAN's announcement has generated significant excitement regarding the future of VLC media player functionality, this advancement also underscores the rapidly evolving landscape of AI-powered media consumption. The seamless integration of translation directly into media players suggests a future where language barriers are significantly reduced, opening up a vast library of international content to a wider audience. For users accustomed to the convenience of built-in subtitles, this upcoming feature in VLC promises a streamlined and user-friendly alternative to the often cumbersome process of manually searching for and downloading subtitles for different languages.
Exploring Real-Time Movie Translation
If you’re unfamiliar with PotPlayer, it's a remarkable media player that rivals VLC. PotPlayer boasts the ability to play all common audio and video formats without requiring additional codecs. It's packed with features and customization options, giving users complete control over its interface and performance. However, its most prominent advantage is its superior subtitle support. It allows for the addition of all common formats like SRT, ASS, and SSA, and offers the capability to download suitable subtitles directly from multiple sources. Most importantly, it provides tools for automatic subtitle synchronization and real-time subtitle generation—the feature we'll detail here. This powerful media player functionality has already proven invaluable for those seeking a flexible and feature-rich way to manage their media files. The added benefit of its AI-powered translation capabilities solidifies its position as a top contender in the media player arena.
This feature relies on OpenAI's Whisper technology, a sophisticated speech recognition system. The program analyzes the audio in the video, extracts the spoken text, translates it into the user's chosen language (such as Korean Spanish Arabic Italian ), and displays it in real-time during playback. Crucially, this process happens entirely locally on the device, eliminating the need for an internet connection. This is likely the method that VideoLAN plans to implement in its upcoming VLC update. In the following sections, we'll detail how to use this feature in PotPlayer. This offline functionality is particularly significant for users in areas with unreliable or limited internet access, ensuring consistent and uninterrupted media viewing.
Steps to Automatically Translate Movies Using AI
First, download and install PotPlayer on your device, either from its official website or the Microsoft Store. The program is exclusively available for Windows users. Next, you need to download the OpenAI Whisper engine and the AI speech recognition model to use the translation feature offline.
To do this, open the program, right-click anywhere, hover over "Subtitles," select "Create subtitles from audio" from the dropdown menu, and then click the same option from the subsequent dropdown menu. The accessibility and ease of installation are critical factors in the overall user experience, making this process straightforward even for less tech-savvy individuals.

A new window will appear where you can select the appropriate version of the Whisper speech recognition engine from the "Engine" list. We recommend "Whisper-Faster" as it's compatible with a wide range of devices and consumes minimal resources. Click the "Download" button and wait for the engine data (approximately 1.3 GB) to download. The clear instructions and user-friendly interface ensure that the download and installation process are seamless and trouble-free. The detailed explanations provided help even novice users navigate the process with confidence.
Next, select the model type from the "Model" list to determine the foundation Whisper will use to convert speech to text. You'll find various models differing in size and accuracy. Based on our experience, we recommend "Large-V2" for its superior accuracy. Although a newer version ("Large-V3") exists, it currently suffers from slow speed and reduced accuracy, making it unsuitable for movie translation You can try it yourself, it may be improved with future releases.. Once you've chosen your model, click "Start" or "Download" to begin downloading the necessary files (up to 3.09 GB maximum for the largest model). The clear explanation of different models and their respective performance characteristics empower users to make informed decisions based on their system resources and desired accuracy levels.
After downloading both the engine and the model, you can create AI-powered subtitles for movies and videos in PotPlayer, even offline. To test the feature, play a foreign-language video or movie in the program, then open the "Create subtitles from audio" window as described earlier. However, this time, select Korean Spanish etc. or any other language from the "Language" list and click "Start".
PotPlayer will extract the audio from the video, use the Whisper engine to convert the spoken words into text, and then automatically translate and time-align it with the video. This process can take some time; in our testing, it took 25 minutes to generate subtitles for a two-hour movie. The detailed step-by-step instructions accompanied by clear screenshots ensure that even those new to PotPlayer can successfully create their AI-generated subtitles. The information provided helps users understand the underlying processes, enhancing their comprehension and providing a more enriching experience.
Once the translation is complete, PotPlayer will display it with the movie automatically, allowing you to enjoy the video or movie with accurate AI-generated subtitles. Note that closing the program will delete the subtitles, so it's best to save the subtitles as an SRT file for later use. To do this, right-click in the program, select Subtitles, then "Subtitle Saving," and finally "Save subtitle as" to choose a save location. The clear explanation of how to save the generated subtitles ensures that users can retain their work and access it conveniently at a later time. This critical step is crucial for preserving the effort invested in generating the subtitles, which can be particularly relevant when dealing with longer videos.
