Short Circutz was a series of short computer animated videos that were played on YTV. Most videos were 30 to 120 seconds long, often played between other computer animated shows, such as ReBoot and Beasties. The videos were all sampled from three film collections: The Mind's Eye, its sequel Beyond the Mind's Eye and Imaginaria. Some of the films were re-edited with alternate music and sometimes songs, in order to appeal to children.
The YTV Viewer Relations Department had this to say, in regards to the reason behind these shorts:
In the past, YTV had only 8 commercial minutes per hour all day, compared to the conventional standard of 12. Often, programs that were acquired for broadcast on YTV had been formatted for the additional commercial time and therefore required interstitials, such as 'Short Circutz', Public Service Announcements or promos to fill left over air time. With the use of 12 commercial minutes per hour, we are now able to air programs as they are formatted without the use of additional fillers.
Here is an official list of the 32 shorts, from the YTV Viewer Relations Department.
