Upload Speed

Even when Kaltura MediaSpace is running smoothly, other internet service providers may experience slower service, which could limit your upload speed. 

  • Upload speeds and Kaltura's upload performance varies, but an upload speed of 10 Mbps should be able to upload a 250 MB file to Kaltura in about 4.5 minutes.


The amount of time it takes Kaltura MediaSpace to process a file depends on file size, duration, quality, and usage.

Generally it takes about 2-3 times the video's duration for Kaltura MediaSpace to display your video in low definition (high definition versions take longer to process). For example, a 15 minute video will usually take about 30-45 minutes to process (in low-definition). When Kaltura MediaSpace is being heavily used, processing times will lengthen and could take up to 24 hours. 

If your video takes longer than 24 hours to process, please call the DoIT Help Desk. More detailed information is available in Kaltura's document involvingtranscoding times and quality of service.

Uploaded Media can be found under the My Media button on the title bar. You cannot preview or publish a video while it is being processed but can edit media information. After you've uploaded your media you may want to review Canvas - Upload and Embed a New Kaltura Mediaspace Video in a Canvas Page [UW-Madison].
