How to convert your video to the right format for faster upload?

Before uploading videos to the platform, convert large video files to mp4 format with the following settings:

  • Video encoder: H.264 or AVC codec

  • Audio encoder: AAC or mp4a codec

  • Maximum resolution: 1280 x 720 pixels

Handbrake is a tool you can use to convert your videos:

Download and install the converter from the Handbrake website

 

 


Video files uploaded to OpenLearning are checked to ensure that the video and audio is encoded in a way that is suitable to be delivered over the internet. 

It is recommended that video files fit the following criteria prior to upload:

  • Videos are exported as mp4 files
  • The H.264/AVC codec is used for video compression

  • The AAC/mp4a codec is used for audio compression

  • The video has a maximum resolution of 1280 pixels in width and 720 pixels in height

A video file meeting these criteria will be uploaded to OpenLearning as quickly as possible without incurring any further processing delay. 

In some parts of the platform where learners are prompted to share video files, the learner can still choose to continue the upload by selecting "Convert my video". However, this may involve a slow upload of an unnecessarily large file (if your video is unoptimised) and the video will not be made available immediately, as further processing (transcoding) is required after the file upload has completed.

To avoid slow uploads and transcoding delays, video files can be prepared in the recommended format prior to upload. This can be done by:

  • exporting the video from your video editing software in the appropriate format, or

  • using a desktop application (such as the free tool “Handbrake”) to convert the video.

  • Download Handbrake from https://handbrake.fr/ and install.

  • Open Handbrake, and immediately you would be prompted to choose the video to convert (otherwise select the “Open Source” button on the toolbar).

  • Select the video file to convert.

  • Choose the “General > Fast 720p30” as the preset.

  • Choose “MP4 File” as the format.

  • In the “Save As” field, type file name for the converted video file. For example: “output.mp4”. (Select the “Browse” button to choose a different location to save the converted video file.)

  • Press the “Start” button to begin conversion.

  • Upload the converted mp4 file to OpenLearning.
