Supported Video Formats in LearnWorlds

Incorporating videos into your courses is essential for achieving optimal learning outcomes, as they have a significant impact on learning. Video allows for more effective processing of information and memory retention than text or any other type of visual or non-visual content. 

In this article, we will go through the supported video formats in LearnWorlds, including the video file type, resolution, and size

Video File Type

Uploading a video in LearnWorlds is not as much a question of file formats, but rather of video codecs used in the specific files. We do support most major codecs, but for best results, we recommend H.264 or Apple ProRes 422.

Some major video file extensions supported are:


If this is getting too technical for you, then just make sure that you are uploading a .mp4 or .MOV video file!

Video Resolution

We support videos up to 4K resolution, however, ultra high definition video may be slow on users with slower internet speed. The recommended video resolution is 720p (1280 x 720px) and the recommended frame rate is 24-30 frames per second (fps).


  • The auto-choose video resolution depends on various factors like:

1. The speed of your internet connection.

2. Video player/screen size: Higher-quality videos generally play better on larger screens.

3. Quality of the originally uploaded video: If the video was recorded in standard definition, it won’t be available in high definition.

  • The suggested aspect ratio is 16:9.
  • Constant quality RF value ranges from 51 to 0. A higher RF number produces higher-quality video, and a lower RF number produces lower-quality video. The recommended values per definition are:

1. For standard definition (480p/576p), set RF to 18-22.

2. For high definition (720p), set RF to RF 19-23.

3. For full high definition (1080p), set RF to 20-24.

4. For 4K ultra-high-definition, set RF to 22-28.

Video size

We suggest uploading video files up to 1 GB to avoid any loading/buffering issues that may affect the user experience. Nevertheless, in the majority of scenarios, you don't require such a large file size, and your high-definition videos can be significantly more compact. We recommend you compress your files as much as possible, especially if you are using 720p or 1080p. This will save you a lot of time from uploading and encoding these videos.

To compress your videos without losing the quality you can use a tool like Handbrake.
