File Size and Kaltura

It is suggested that you do not shoot video in high definition (HD) or the highest resolution setting of your recording device. Doing so usually results in a video that takes too long to upload. Also, a reliable/strong internet connection is required for video uploads.

Although it is possible to upload a video file that is as large as 2GB, it will take a long time to upload and is more likely to fail during the process. In turn, it is a good idea to reduce large video files prior to uploading them to Blackboard. You can try using one of the methods below to reduce the file’s size. Another option is to record videos in shorter 5-10 minute segments instead of hour-long videos.

Converting Video Files with Handbrake
