It is a fact that videos have an effect on learning and can offer the most effective learning outcomes. Consequently, integrating videos into your courses becomes a crucial endeavor, requiring nothing more than access to a quality camera and microphone.
In this article, we will go through the supported video formats in LearnWorlds, including the video file type, video 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. In most cases, if you have a .mp4 or .mov video file you will be just fine.
You shouldn’t have any problems uploading videos with other major video file extensions like:
MOV, MP4, 3GP, DIVX, AVI, FLV, MPEG, MPG, WMV, MKV
If this is getting too technical for you, then just make sure that you are uploading an 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).
Notes:
- The auto-choose video resolution depends on various factors such as:
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
LearnWorlds supports file sizes up to 1 GB. 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 really compress your videos without losing the quality you can use a tool like Handbrake.
