Having trouble uploading?

A.1: Oftentimes problems occur if you're uploading a file in the wrong format. Make sure you’re using a supported file type: MP4, FLV, MOV or WMV. (We suggest MP4.)

A.2: Make sure you’ve updated your browser to the latest version. Older browsers can oftentimes cause problems. Below are some of the browsers we recommend using to upload videos:
  • Google Chrome
  • Firefox
  • Safari

A.3: Try using Chrome incognito window or Firefox Private Browse to upload your video. This will temporarily disable browser extensions. Ad blocking extensions, for instance, are often responsible for these problems.

A.4: Temporarily disable anti-spyware, anti-virus, or similar software. These programs also usually cause problems.

A.5: Try plugging your computer directly into your modem with an ethernet cable, rather than connecting wirelessly through a router to improve your Internet connection.

A.6: TeacherTube Upload has a 300 MB maximum file size which, at typical video compression rates, should be around 15 minutes long or roughly 9 seconds per 1 MB. If your file is larger than 300MB and still under 15 minutes then you should open it in your video editing software and export it to a new, compressed file with one of our accepted formats and a higher compression setting. An example of this from a TeacherTube User experience that had a video file which started out at 3 gigabytes. After rendering in Final Cut Pro Software Program it was reduced down to 65 MB, and uploaded to TeacherTube with no problem. 

A.7: Often times if you upload your file from an external source such as an USB, external drive or network drive, errors will occur. Move the video file to your desktop or locally to your computer that you are uploading to TeacherTube.

Audio/Video problems

If you’re having problems with your audio or video, making some changes to your video will usually solve the issue.

Audio and video are out of sync

Make sure the duration of your audio and video tracks are the same. For example, if your audio is playing for 40 seconds but your video is playing for 50 seconds, that could be the cause of the problem.

You can use a third party video editor like Windows Movie Maker or iMovie to change the length of your audio and video tracks.

Other problems

Step 1: Open your file with a video editing tool like iMovie, Final Cut Pro, or Quicktime Pro.

  • In iMovie, select Share > Export Using QuickTime
  • In Finalcut Pro, select File > Export > Using Quicktime Conversion
  • In QuickTime Pro, select File > Export > Export: Movie to QuickTime Movie
