    Supported file types and sizes for Mr. Transcription. How to make unsupported files compatible

    Mr. Transcription's Supported File Types and Sizes. How to Make Incompatible Files Work

    We'll guide you on Mr. Transcription's supported file types and what to do when your file isn't compatible.

    When using Mr. Transcription for transcription, you might occasionally encounter errors and be unable to transcribe, even with supported files.

    【Main causes include】

    1. Transcription gets stuck in "processing" due to timing or some other reason
    2. The transcription limit has been reached
    3. Upload failed
    4. An error occurred due to network environment or browser issues
    5. The file name contains emojis
    6. The file name is too long
    7. The file contains no recorded speech (e.g., prolonged noise, silence)

    etc.

    When you can't transcribe successfully due to these issues, there are very simple solutions.

    We will introduce each solution.

    If transcription is possible, but:

    • The transcription is not accurate
    • The transcription consists of repeated unknown characters like "aaaaa"
    • The transcription is incomplete or "gappy"

    To achieve highly accurate AI transcription, several recording techniques are crucial. This article introduces optimal recording tips for AI transcription. High-quality microphone Proper microphone placement Create a quiet recording environment Ensure clear speaker articulation Single...

    Reason 1: Transcription gets stuck in "processing" due to timing or other issues

    When you upload a file and start transcription, sometimes the transcription request communication gets stalled for some reason, and the transcription gets stuck in "processing".

    If it's stuck in "processing," your available transcription time will not be consumed.

    This error is less likely to occur with image files but more common with long audio files.

    If "processing" continues for more than twice the duration of the uploaded file, please try "Try transcribing again."

    If transcription is stuck in "processing"

    For example,

    • Remaining transcription time: 4 hours
    • Uploaded a 1-hour audio file and started transcription

    If your account is in this state and transcription hasn't completed even after twice the audio file's duration (2 hours in this case) has passed, it's an error.

    Solution 1: Retry / Try transcribing again

    If transcription doesn't complete after twice the audio file's length, you can retry.

    When you open the history, a "Retry" button will appear.

    Alternatively, clicking "Edit" for the target file will display a "Try transcribing again" button.

    Click either of these to attempt transcription.

    You can resubmit the transcription request without re-uploading the file or consuming additional transcription time.

    Solution 2: Delete the file

    Deleting the erroneous file will release the "processing" time that was locked.

    ※Please note that deleting a file after the renewal date will not restore the locked time. Avoid performing this action across renewal dates.

    If an error occurs,

    1. Try again
    2. If it still fails, delete it

    Please follow these steps.

    Precautions for retrying and deleting

    For files that do not contain transcribable speech (e.g., no human voice, or audio too noisy to be understood),

    pressing the "Transcribe again" button will consume transcription time.

    Also, deleting the file will not recover the transcription time.

    Please be careful not to upload audio that humans cannot clearly hear.

    【Audio that cannot be transcribed】

    • Music with lyrics, etc.
    • Audio with severe noise that drowns out speech
    • Audio with no sound
    • Audio where human speech is difficult for a person to hear

    For such audio, the AI cannot transcribe it, no matter how many times you try.

    Reason 2. Reached the transcription limit

    Mr. Transcription has a set transcription limit for each plan.

    If you reach this limit, you won't be able to transcribe any more for that month.

    • If you are not a member, register for a free membership.
    • If you are a free member, subscribe to a paid plan.
    • If you are a paid member, cancel your current plan once, then re-subscribe to your preferred plan to increase your transcription capacity.

    These steps can resolve the issue.

    The available "minutes" for audio transcription and "number of images" for image transcription are distributed monthly.

    Updates occur every 30 days.

    Details for each plan are as follows:

    • Non-member: Free
          1 minute of audio/month
          3 images/month
    • Free Member: Free

    Regarding Mr. Transcription's Paid Plan Payment Timing, How to Change Plans, and Important Notes

    This article explains the payment timing for Mr. Transcription's paid plans, how to change plans, and important considerations.

    Reason 3. Upload failed

    A common sign of a failed upload is when the progress bar repeatedly moves to the right and then returns to the beginning.

    Normally, once the upload is complete, the progress bar disappears, and you will see either:

    • "Transcribed content"

    or

    • "For files longer than 10 minutes, you will be notified by email upon completion of transcription."

    will be displayed.

    We will explain the causes and solutions when the bar repeatedly moves to the right and then returns to the beginning.

    There are cases where you might encounter an error and be unable to upload audio or image files to Mr. Transcription due to reasons such as unsupported file size or format, timing issues, or a slow internet connection.

    Additionally, for video files, Mr. Transcription's system first converts them into audio files before processing the transcription. Errors can occur if this internal conversion process fails.

    1. Incorrect File Size or Format

    This is the most common cause of errors when using Mr. Transcription.

    • 【Image Files】
      Supported file formats:  .jpg .jpeg .png .webp
      *If the text is sideways or upside down, transcription may not be possible. Please correct the orientation.
    • 【Audio Files】
      Audio duration: within 90 minutes
      Supported file formats:  .mp3 .wav .wma .mp4 .aifc .flac .aac .aiff .aifc
    • 【Video Files】
      Audio duration: within 90 minutes
      Supported file formats:  .mp4 .mov .avi /flv .mkv .webm .wmv .3gp

    File size: up to 1GB

    Many users overlook these specifications. Please double-check the file you are trying to upload to Mr. Transcription.

    Learn about Mr. Transcription's supported file types and sizes, and what to do if your file is not supported.

    2. Upload Failure Due to Timing Issues

    Sometimes, an upload might fail due to timing issues, leading to a timeout where the transcription process never starts.

    If you are in an environment with an internet upload speed of 80Mbps and the upload hasn't succeeded after 10 minutes, please try uploading again.

    When attempting to re-upload:

    • Reload (refresh) the Mr. Transcription page

    Please reload the page before trying again.

    3. Internet Connection is Too Slow

    • Large image file sizes
    • Audio files that are several hours long

    In such cases, a very slow internet connection can lead to errors.

    Even with smaller file sizes, a slow internet connection can cause uploads to time out or be canceled midway, resulting in an error.

    To prevent this, use a high-speed internet connection like fiber optics, or ensure you have a strong Wi-Fi signal if using wireless.

    When attempting to re-upload:

    • Reload (refresh) the Mr. Transcription page

    Please reload the page before trying again.

    4. Video File Conversion/Upload Failed

    For video files, Mr. Transcription internally converts them into audio files. Sometimes, this conversion process can fail, causing an error.

    If you're uploading a video file and encounter an error, converting the video to MP3 using an external site before uploading it to Mr. Transcription often resolves the issue.

    If you experience errors, try converting your video to MP3 first, then upload it.

    Cause 4. Browser-Related Errors

    Errors can also occur due to browser-related issues.

    Mr. Transcription's Recommended Browser

    If you're consistently unable to transcribe, checking your browser is a crucial step.

    What type of browser do you usually use when accessing Mr. Transcription?

    Mr. Transcription recommends Google Chrome as its primary browser.

    If you're encountering errors, please try the following:

    • Switch to Chrome
      (However, if you're already using Chrome, try a different browser)
    • Use Chrome's Incognito window

    Please give these a try.

    Download Google Chrome

    How to Open an Incognito Window

    What is an Incognito Window?

    It allows you to browse websites without saving your browsing history or information entered into forms.

    To use an Incognito window:

    1. Click "File" in the toolbar
    2. Select New Incognito Window

    Alternatively,

    1. Press [Ctrl] + [Shift] + [N] keys

    You can open it this way.

    Please try it once.

    Reason 5. Emoji in the File Name

    If your file name contains emojis, uploading will fail.

    Please do not include emojis or other special characters in file names.

    Reason 6. File Name is Too Long

    If the file name is excessively long, uploading will fail.

    We recommend keeping file names under 15 characters.

    Reason 7. No Voice Recorded in the File (Noise, Silence, or Extended Music)

    If you upload an audio file without checking its content, you might find:

    "Recording failed and it's silent" or "Microphone disconnected during recording, so only noise is audible, no voice."

    Additionally, there might be instances where "music, noise, or silence continues for several minutes at the beginning or in the middle."

    The image above shows the transcription result after uploading a file that contained only noise.

    Mr. Transcription uses AI for transcription. AI attempts to transcribe as much as possible, even in noisy or musical sections.

    This issue is particularly common when the file has more than one minute of noise or silence at the beginning.

    If you get strange transcription results like "aaaaaaaaaa" or "nnnnnnnnnn", or if the same phrase is repeated many times, please check the file's content.

    We cannot refund transcription time consumed by files like the ones described above.

    To successfully transcribe, you can use audio editing software like MP3 Cutter to cut out problematic sections before uploading.

    Splitting MP3s is easy with online tools or free installable software.

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

    Audio Files That AI Transcription Services Struggle With

    1. Audio that is too quiet, or where the microphone is too far away, making it hard to hear.
    2. Audio with excessive noise that drowns out the speech.
    3. Audio where indoor reverberation blurs the sound.
    4. Audio containing music, such as song lyrics.
    5. Audio with no speech or sound.
    6. Audio with strong dialects or accents.
    7. Audio where human listeners find the voices difficult to understand.

    AI transcription has strengths and weaknesses when it comes to the audio files it transcribes.
