Video Correction for Pinnacle Studio MP10

Published in issue 290, July 2000

Video Correction for Pinnacle Studio MP10
The Pinnacle Studio MP10 is an external real-time MPEG1 codec that includes composite video input and output. The output provides only 0.7 V, which is too low for most video equipment. Many video inputs are standardised for 1-V signals. The low output level of the MP10 can easily be corrected. The correction circuit, with its own small power supply, can also be used for many other applications.
