Case Study – Ravensbourne
Ravensbourne partners with root6 for Broadcast Deliverables course
“It was very useful for the students to learn from root6’s experience at the coal face”
Reseller and Systems Integrator root6 recently partnered with Ravensbourne to deliver a course on Broadcast Deliverables to students in The Department of Production. As an industry-focussed university sector college, Ravensbourne operates a state-of-the-art technical facility and places great emphasis on practical skills, resulting in a high level of graduate employment. Last year, with the aid of root6, the faculty revamped its Avid estate, installing a 128TB ISIS network with Interplay, Airspeed and MediaCentral, greatly streamlining its collaborative workflow in the key areas of broadcast and post.
The course provided by root6 and delivered by Chief Engineer Phil Crawley and Product Specialist Bill Baker forms part of a unit on post production technology. The topics covered included an overview of QC, a discussion on MXF and the AS-11 UK DPP delivery standard with specific reference to file-based QC.
“With close links to the broadcast, production and post communities, our courses are driven by industry standards,” explains Caroline Orme, Senior Lecturer in Broadcast Post Production at the faculty.
“Consequently it was very useful for the students to learn from root6’s experience at the coal face.”
Crawley outlined the importance of video levels with reference to EBU Technical Recommendation R103 concerning “Illegal” colours in television and described how colour is encoded and why gamut errors are problematic. Moving on to audio, he discussed the importance of levels and loudness and how they can be monitored in both baseband and file-based domains. Finally, Crawley addressed the issue of photosensitive epilepsy (PSE) and its measurement to ensure deliverables meet Ofcom regulations.
Having looked at the general principles of QC, Baker moved on to the practicalities of making compliant file-based deliverables. Following a resume of the DPP initiative the AVC-I 100Mbits MXF format was examined in detail. Typical Avid transcode workflows were described and how Vidchecker might be deployed for marshalling material and wrapping the associated metadata back into the MXF sidecar. Finally, typical delivery mechanisms were described including accelerated WAN services.
“Practice-based workshops such as those provided by root6, provide valuable insight for our students,” concludes Orme.”It keeps them thoroughly up to date with new industry standards such as the AS-11 UK DPP criteria for broadcast deliverables and the technologies available to implement them.”
root6 offer a range of training courses to meet particular requirements and, as a certified Avid Learning Partner – Professional, deliver accredited courses for Interplay and ISIS. More information here.
