How to automatically add subtitles to videos and translate them through AI?

With the advent of the digital age, video has become an important medium for information dissemination. However, for a global audience, language barriers often become a bottleneck in accessing information. Fortunately, with the help of artificial intelligence technology, we can easily add subtitles to videos and translate them into multiple languages. This article will detail how to use AI technology to achieve this goal.

First, we need to choose the right tool to handle video subtitle generation and translation. A very efficient option is to use Aegisub software. Aegisub is a free and open source subtitle editing software that supports multiple subtitle formats and can easily import and export subtitle files. In addition, Aegisub also provides powerful timeline editing functions, making it easy and fast to adjust the subtitle display time.

Next, we can add subtitles to the video in Aegisub by following these steps:

1. Open the Aegisub software.

2. Click the "File" menu, select "Open Video", and then select the video file to which you want to add subtitles.

3. Using the "auto-sync player" function, Aegisub will automatically create subtitles based on the audio content.

4. Enter text in the subtitle window and manually adjust the time point of each subtitle.

5. Save the subtitle file, you can choose srt, ass and other formats.

After completing the above steps, the original subtitles of the video have been added. But in order to make the video content understandable to more people, we will further translate it into other languages. At this time, we can use online translation tools such as Deepl Translator to help us complete this task.

The steps for translation using Deepl Translator are as follows:

2. Copy and paste the subtitle text that needs to be translated into the input box on the left.

3. Select the source and target languages ​​from the drop-down menus.

4. Click the "Translate" button and the translated text will be displayed on the right.

5. Copy and paste the translation results back to the corresponding time point in Aegisub.

Finally, save the modified subtitle file, making sure it is in the same directory as the original video file. At this point, you can use video editing software (such as Adobe Premiere Pro) to embed the generated subtitle file into the video. In this way, you can get a video file that contains both the original language subtitles and the target language version.

In short, with AI technology and some professional software tools, adding subtitles to videos and translating them is no longer a problem. This not only helps break down language barriers but also allows video content to reach a wider audience. I hope the methods introduced in this article can help everyone better use videos to share knowledge and information.
