There are many benefits to a file-based workflow. One of those is the ability to automatically check video for a laundry list of errors and if the file meets compliance specifications. It is important to understand what can and cannot be properly measured in file-based content with today’s automatic QC and test-and-measurement tools.
In the fourth season of 'Bruce's Shorts', Bruce Devlin takes a look at the Interoperable Master Format (IMF). In this episode he answers the question, How do you QC IMF?.
IMF is made up of many components. But, how does one QC an IMF file in a file-based environment and why is it necessary? Is there an official checklist?
In Part 4 of his series about IMF, “How do you QC IMF?” Devlin walks readers through the primary QC processes.

Video and audio bring a new dimension to monitoring for the IT department. Not only are we concerned with how to measure aspects of the video and audio signals, we also must analyze the time it takes for an IP packet to arrive at a destination, and the variance of all other packets in the stream. If they take too long to be delivered, then the receiver will drop them from the decoding buffer, which causes signal corruption.
IT networks use packet analysis tools such as Wireshark to look closely at the packets, and IPerf is used to find absolute maximum data rates of network links. Learn more about this and the measurement process in Tony Orme’s tutorial, “Understanding IP Networks - Packet Delay Monitoring.”
Tony Orme has posted almost 30 additional tutorials in his on-going training series on The Broadcast Bridge website. They can be found by searching for “Tony Orme” in the homepage search box.
