Learn How to Translate YouTube Videos Using ChatGPT!

1. What is ChatGPT? What Can You Do with It?

1-1. What is ChatGPT?

ChatGPT is a very large language model developed by OpenAI. This model utilizes artificial intelligence to communicate with users in a chat format. ChatGPT learns mainly from a large amount of the text data available on the internet, and its ability to generate natural-sounding sentences, similar to those written by humans, is its main feature.

1-2. What can you do with ChatGPT?

ChatGPT can converse like a human, create emails, blogs, and scenarios, generate ideas, summarize long texts, and translate, depending on the instructions given (called prompts). It can also be used for information retrieval, proofreading of text and code, creating proposals, creating templates for presentation materials, and generating programming code.

2-1. Translating with ChatGPT

ChatGPT was trained on multilingual data from the internet and is capable of translating between languages. In addition to English, it supports Japanese, Spanish, French, German, Italian, Portuguese, Dutch, Russian, Chinese (simplified and traditional), Korean, Thai, Indonesian, and more. While there is no official information from OpenAI regarding which languages are supported, estimates range from 50 to 100 total.

To translate, write a prompt such as "Translate to [target language]," and then enter the text to be translated. ChatGPT will automatically detect the language in the prompt, so there is no need to specify the language of the original text. For example, when ChatGPT was asked to translate the prior paragraph from its original Japanese, here's what it came up with:

You can use ChatGPT to translate videos. There are two ways to go about this: either translate the subtitles included in a video or transcribe video's audio and then translate the transcribed text. Both methods are explained below.

3. How to Translate Video Subtitles with ChatGPT

The following steps will explain how to translate video subtitles with ChatGPT from English to Japanese and add the Japanese subtitles to your video. For this, we will use YouTube Studio. YouTube Studio is a free analysis and management tool provided by Google for your own YouTube channel.
To use it, access https://studio.youtube.com/ in your web browser.

1. To download the subtitles from a video, click "Subtitles" in the left-hand menu of YouTube Studio and then click on the desired video.

You can choose from the following formats: .vtt, .srt, or .sbv.

4. Copy the output of ChatGPT. Create a new file in your text editor, paste the text, and save it. The file extension you use must be the same as the downloaded subtitles file. If you downloaded an .srt file, the extension of the saved file should also be .srt.

5. Back in YouTube Studio, click the "Add language" button, click "Japanese", and then click "Add" (the pen icon). Click on "Upload file", "With timing", and then "Continue," and select the file created in Step 4 to upload. Finally, click "PUBLISH" to make the subtitles public.
