This is one of the main gripes Post houses and Facilities have with the broadcasters. We have a UK broadcast standard (thanks to the DPP) that clearly states no blanking is permitted in HD content. (Actually it’s not blanking and hasn’t been since we moved from analogue. It’s just non active content which is normally black.) Plus a whole load of other requirements. Who gets to see content that hasn’t got burnout highlights nowadays? Tech spec clearly states content should be properly exposed.
I hate to blow up content to fix a 1 or 2 pixel non active content issue as it softens the image. (often a slightly bigger blow up will look better) But the better solution is to crop the non active content and the underneath the image have a blown up copy. So effectively you sort of clone that edge.
No loss of quality that way.
At VET I’ve been delivering a 3 day Broadcast QC course (shameless plug) http://vet.co.uk/training/courses/vet-technical/qc-quality-control/ (skillset funding available for this)
This is aimed more at tackling the more traditional QC techniques but has already started to evolve into the new file based delivery and QC issue.
A lot of bigger facilities use this course or a bespoke version to harmonise their QC staff and the way they report QC.
We hope to have a fully AS-11 file based QC course available soon (2 or 3 days not sure which yet) which will cover eyeball QC as well as AQC and workflows.
We already cover a whole range of loudness, AS-11 and DPP related half day courses and an ongoing issue raised by the technical people who attend is the widening gap between what broadcasters document as requirements and what they actually accept and broadcast.
It’s almost like the spec is so far off what’s being produced everything is a fail technically. Leaving Post Houses in a vulnerable position.
The DPP linkedin group is a useful place to raise issues like this as a number of senior Posthouse and facilities folks hang out there as well as some broadcast input.
I’m happy to discuss issues as well.
