Strategies for Screen Reader Encoding and Uploading

We are using Kaltura integrated in Moodle. When a user goes to My Media to do a Screen Recording, the encoding and uploading process takes a little longer than the original length of the recording. While this is processing, we cannot start another screen recording on that machine, and the user needs to wait for this lengthy process to complete before leaving the computer. Is there a better way to deal with this post recording encoding and uploading process?
