• Troubleshooting Closed Caption Upload Errors

    This article outlines the error notifications instructors might encounter while attempting to add closed captions to your course lectures, and how can you resolve the issue.

    For steps on how to add closed captions to your course videos, please click here.

    Incorrectly Formatted Timing Information

    If your caption entry includes timing information the system cannot read, then you will see an error notification reporting one or more of the entries has incorrectly formatted timing info.

    In order for your .vtt closed caption entry to be accepted, it must be formatted with one of the timing formations below:

    00:00:00 (HH:MM:SS)

    00:00 (MM:SS)

    00 (SS)

    00:00:00.000 (HH:MM:SS.mmm)

    00:00.000 (MM:SS.mmm)

    00.000 (SS.mmm)

    Please note: ‘m’ stands for microseconds

    In addition, caption entries must have a start time that is earlier than the end time that’s been entered, in order for it to upload successfully. Accordingly, the caption entries also require a start time that is later than the previous entry’s start time.

    If you receive an error sign indicating this is not the case, then you will need to edit the entry’s times.

    Missing Timing Information

    If the .vtt file has a correct header, but doesn’t have any timing information, or it can’t be recognised due to incorrect formatting, you will see an error sign reporting that one or more of the caption entries has text but no times.

    The correct formatting for the timing information looks like “00:03:00.000 --> 00:05:00.00”. Please note that the separating arrow must have one or two space or tab characters on each side.

    missing_times.png

    Missing WEBVTT Header

    If the caption entry is missing the WEBVTT header, which is required for valid vtt files, you will see an error warning indicating this. Please add WEBVTT to the first line of the file in order to resolve the issue, as shown below:

    missing_WEBVTT.png

    Missing Track Text

    If one of the caption entries has timing information but no text, you will be notified via an error sign. Each caption entry should have a start time, end time and some text in the following format:

    missing_text.png

    No Caption Entries

    Each caption entry should have a start time, end time and some text, and each caption entry must be separated from another with at least two line breaks. If the entry doesn’t, an error sign will appear indicating that there are no recognisable caption entries in the file.

    Caption entries should be created with the following format:

  • Mobile Course Inclusion FAQ

    When is my course added to the mobile apps?

    On the day that your course is published, it will be automatically submitted to our iOS and Android apps. Please note, it may take between 3-6 weeks for Apple to approve a course and add it to the iOS marketplace. Also in the case of the iOS app, once approved the course will receive a 30 day trial. After 30 days have passed, your course will be subject to certain requirements, which will need to be met in order to keep the course in the iOS app store.

    What are the mobile app requirements after 30 days? Why is my course not appearing in the iOS app marketplace?

    Currently, Apple restricts the number of course that can be featured on the iOS mobile app, and as a result, courses must meet certain requirements in order to remain in them. 

    The most important requirement from Udemy is the monthly revenue for the course: it will need to exceed over $30 dollars per month. The revenue requirement is for the total sales of the course that occur via any Udemy platform (Udemy.com, iOS app etc).

    If after 30 days of your course being published on Udemy, you search for your course on the iOS app and it doesn’t appear, the course revenue likely did not reach the requirement.

    In the case of the Android app, however, all public and approved courses will be available for purchase on the Android app. There are no revenue requirements for a course to remain on that marketplace.

    How do you get back on our iOS app?

    Your course has a chance to be featured every month on our iOS app so long as you are generating > $30 of revenue. So if for some reason your course did not reach the revenue requirement for a particular month, the course will have the opportunity to be added to the iOS app next month, provided your course fulfills the requirement.

    In order to return your course to Apple mobile app store, your course will need to generate over $30 in revenue in a proceeding month. Once the course earns this amount in sales, please email instructorsupport@udemy.com to be added back into our app stores. 

    Here are some things you can do to boost your course revenue:

    https://teach.udemy.com/your-first-30-day-promotions-plan-on-udemy/
    https://teach.udemy.com/course-promotion-carnivale-optimize-your-youtube-channel/
    https://teach.udemy.com/ultimate-guide-to-becoming-a-bestseller/

    If you have more questions around this, or would like to dispute your course’s mobile inclusion status, please email instructorsupport@udemy.com.

  • Supported File Types

    The Udemy platform supports several different types of files for lectures, and many types of files for additional resources, if you wish to include more content that students can download.

    Supported Files for Lectures

    Udemy courses can include article, video and mashup lectures, and these can be created using several different types of files.

    • Article lectures can be created using the platform’s built in, text editor, and .JPG, .PNG .BMP and .GIF files can be inserted into the article using the add image option. Please note that the image files must be smaller than 1 MB.
    • Video lectures can be built by uploading .AVI, .MGP, .MPEG, .FLV, .M2V, .M4V, .MP4, .WMV, .OGV, .WEBM and .MOV files. We recommend using MP4 files if possible, however, as we have found the uploading process works best with these.
    • Mashup lectures combine videos and slides to create a compelling lecture. The video files must be in a .MP4 or .MOV format. The slides, on the other hand, must be in .PDF format. So, if you’re using software like Powerpoint or Keynote to create the slides, you will need to export them as PDFs.

    Supported Files for Additional Resources

    Adding additional resources can be a great way to enhance the lecture, and provide students with a more comprehensive learning experience. Please note: these resources must be available for free, related to the lecture topic, and not promotional in any manner.

    The additional resources section features nearly any kind of file type, including .JPG, .PDF, .ZIP, .XLS, .MOV, .MP3, .PPT, and .DOC, among others. 

    Source code like .HTML, .JS, etc., however, cannot be uploaded directly, but these files can be uploaded in a .ZIP file. 

    Source Code for Development Courses

    Only Python and Ruby files can be uploaded at this time.

    Uploading the Files

    Files can be uploaded to the lecture by using the browser uploader, or by adding them from your library using the bulk file uploader. 

    Please note: .MP3 files for additional resources must be uploaded using the browser uploader. 

    If you have any other questions regarding the type of files the platform supports, please contact us here.
