“QC has to work well with existing customer workflows” — Robert Millis, Harris Broadcast
Is faster than realtime truly efficient?
Ackroyd: File-based processes can operate at the fastest speed the software design can achieve, whether slower or faster than ingest/playout speed Devlin: Yes. I think the question should be ‘Is faster than realtime always needed?’ — in production the answer is probably yes, but in reality, the ‘dismantle the file at the end of the workflow’ approach to QC is ultimately doomed. Unless we learn from other industries that QC is a process relying on accurate measurements at key points within the workflow then we’ll never be able to crack the brute force realtime question. If you want realtime, the best way is to be smart about where, when and what QC you apply and then how you aggregate that data to mitigate business risk. Fabian: Again, this is a question that leads to
QC runs at 30-100x realtime, offering customers the ability to meet their increasingly tight deadlines for production or the requirement to QC large libraries of content in a timely manner.
Millis: Some workflows are based more on speed, such as transcode workflows or those related to live programming. It is always handy to get the automated QC done faster to either allow time for manual
review or potentially a resubmit of a QC job if some parameters are less than optimal. Singhal: The main objective
of ‘Automated QC’ is the improved workflow efficiency. If the same analysis task can be

done faster, the benefits are obvious. Pulsar Automated QC solution can process a HD file up to four times realtime speeds which allows tremendous amount of time and cost efficiency to its users.
Niklas Fabian: “While visual QC focusses on the actual impression, the technical QC takes all those aspects into account”
controversies in the industry. We believe that speed is essential to certain production fields, for example, in the news sector. Realtime-readiness or even more is truly important in this hectic environment. Other fields might not require this certain aspect and have more time in their workflow steps and define efficiency on another level. Kandell: Realtime is a
carryover from the tape-based world, but as applications and hardware continue to increase, we will see this benchmark to be less than acceptable. Nexidia
