6.2 Technical information of pictures and video

Topic Progress:

When you upload pictures to the learning environment, make sure they are either JPG or PNG files. You should also pay attention to the size of the picture before using it – if the size of the raw photo in pixels is in the thousands, it’s recommended to reduce it. It’s recommended to use pictures at least 1,400 pixels wide (unless you’ve decided to use the picture in a significantly smaller size) so that you can place them in the learning material in different ways. The height of the picture doesn’t matter.

When uploading videos, make sure the file format is MP4. That’s because all file formats (e.g. MOV) either don’t work or result in too big file sizes. It’s recommended to use videos with a 16:9 aspect ratio and 720p quality (1280 x 720 pixels).

NB! Remember to add a preview image for all your training videos!

Naming media files

Media files should be uniformly named, especially if there are multiple courses or content producers. This clarifies the course creation and management.

Example of naming:
coursename_5_1_mediafiledescription.jpg

The logic behind the above example is that the file name first contains the name of the course, followed by the numbers of the LESSON (in example: 5) or TOPIC (in example: 5_1 i.e. the first sub-topic of Lesson 5) and finally a description of the media file. In practice, this could be guideforcontentproducers_7_naming.jpg. If possible, the file name should be as short as possible, which means you can use commonly known abbreviations. The media file descriptions should not be too long.

Things to note about naming conventions

  • No special symbols (!,.? etc.)
  • No special letters (e.g. ä, ö, å)
  • No spaces, which should be replaced with underscores ( _ )

The notions above are common conventions of file naming. Special letters, spaces and special symbols are omitted because the web environment doesn’t necessarily understand them and transforms them into incoherent strings of characters. This may confuse the user, so it’s recommended to name the files in an online-friendly format.
