Download SRT File for Video Subtitles

Creating a video subtitle file with Mr. Transcription is very easy.

Just click "Download Subtitles" below the transcription results.

When you click the button, the latest AI automatically processes the transcription results and generates an SRT file.

You can download an SRT file that can be directly imported into video editing software or videos already uploaded to YouTube.

SRT files can also be saved from "Download Subtitles" on the history page.

When you open the saved SRT file, you'll see that its content is in the widely used SRT format for video subtitles, like this:

We will create English translated subtitles based on this subtitle file.

2. Translate SRT File to English with AI Service

Once the Japanese video subtitle SRT file is completed with Mr. Transcription, the next step is to create English translated subtitles.

The recommended method for creating English translated subtitles is:

• Upload and translate the SRT file to an AI service

You can directly upload the Japanese video subtitle SRT file to generative AI services like ChatGPT, Claude, or Gemini and translate it.

The advantage of this method is that you can create subtitle files that can be directly imported into video editing software.

An SRT file contains not only the content of the video subtitles but also information about the subtitle order and time codes that specify when to display the subtitles in the video.

Therefore, you cannot simply translate the content using an AI translation service like DeepL.

However, by using generative AI services such as ChatGPT, Claude, or Gemini, you can translate only the subtitle content while preserving other information in the SRT file.

Example of Instructions for Translating Subtitle SRT Files with AI Services

When translating a YouTube video subtitle SRT file on a generative AI service website, it is recommended to give instructions like this:

Please create an English translated subtitle file from the uploaded SRT file. Keep the time codes and subtitle information as they are.
Please make it available for download as an SRT file.

This allows you to translate only the text part from Japanese to English, while maintaining the SRT format.

Let's actually instruct a generative AI service (we'll use Claude this time).

When you upload the SRT file and give instructions, it translates the subtitles from Japanese to English like this:

The translation results can be downloaded as a file.

When you open the downloaded file, it is in SRT format, as shown here.

*Since it was downloaded as a text file (TXT) this time, we will change the file extension to SRT after downloading.

3. Edit Video Using English/Foreign Language SRT Subtitle File

Now we have created the English translated subtitle file.

All that's left is to import this video file into video editing software and create your video!

Let's actually import it into DaVinci Resolve, a video editing software.

As you can see, it was successfully imported as English subtitles.

Now, just edit the video and upload it to YouTube or social media!
