Mr. Transcription: Supported Files & Easy Conversion Guide

I want to transcribe a 3-hour file, but how can I do it?

You just need to convert it to a file format and audio length that Mr. Transcription supports!

Supported Files for Mr. Transcription

Mr. Transcription supports the following file types. Uploading any other type will result in an error.

*Uploading multiple files is not supported. Please upload one file at a time.

If you upload a file in an unsupported format, an upload error will occur.

Audio and video files that exceed the supported duration are not rejected; the part from the beginning up to the time limit of your plan is transcribed.

What happens if you upload an unsupported file?

If you try to upload a file that is not supported, errors such as the upload not completing will occur.

Example: WAV file, file size 40GB, audio duration 1 hour

Unsupported files cannot be transcribed, no matter how many times you try to upload them.

Also, unexpected operations might consume transcription time even if transcription is not possible.

Please be careful.

How to Transcribe Unsupported Files

When you want to transcribe files that are too large or too long, we recommend:

• Converting them to a supported file format
• Splitting them to match the supported file duration

By changing the file format or splitting the file, the file size will naturally decrease.

Example: Converting an M4A file (video) to an MP3 file (audio only)

Example: Splitting a 3-hour MP3 file into three 1-hour files

1. Convert to a compatible file format (with automatic video conversion)

The video file is too large to upload...

Mr. Transcription can handle such situations!

If you select a large video file on the Mr. Transcription homepage, it will automatically convert it to an audio file and transcribe it!

Split MP3 Files

Splitting MP3 files is easy with online tools or free installable software.

For online tools, MP3 Cutter is convenient and user-friendly.

※When splitting by time, if you split at 90 minutes, transcription can take longer, and file sizes tend to become large. Therefore, it's recommended to split into segments of 1 hour or less.

3. Upload to Mr. Transcription

Once you've split the audio files or converted them to a compatible format, upload them to Mr. Transcription.

Select the language and then choose the audio file, and uploading and transcription start automatically.

If you split the audio file to fit the supported duration, you can transcribe it all the way to the end.

4. Transcription Complete

Once the upload is complete, wait a little and the transcription will be completed.

By splitting the audio according to the remaining time, we were able to transcribe everything without missing a beat!

Please give it a try.
