FCP blanking issues
Anyone out there heard of programmes finished on FCP failing BBC technical reviews due to half line blanking issues at the top of the frame?
I’ve noticed this with AJA IO, Kona 3 and Blackmagic cards.
Anyone found a fix for this (apart from zooming up by 101% or croping the half line)?

I’ve had quite a bit of stuff on the BBC through my Blackmagic cards no problem.
What codec are you using?

I’ve used Blackmagic and AJA 10 Bit codecs. We’ve also had programmes pass successfully for the BBC and ITV no problem, however the half line issue is very noticeable at the top of the frame whatever 10 Bit codec or card is used.
I heard through the grapevine that the BBC were failing beacause of this. I’ve found very little on this issue on forums which is surprising because it is so noticeable.

So you haven’t had a programme fail?

“Extra” half lines at top and bottom are completely normal and expected in NTSC; I didn’t think PAL was any different in that regard. Knowing BBC is sticky on the details, I can imagine one getting in trouble for _not_ having them.

The reason for this post is that this issue was flagged by a potential client who has worked with Avid for many years where this certainly isn’t an issue.

Technically having them there (i.e. not blacked out) shouldn’t be a problem – speaking from NTSC experience. As mentioned above, there’s the possibility that a lack thereof might be a technical infringement.
And it should have little to do with the editing system but more to do with how it was used. If they use a DV format, those lines are stripped out – they aren’t available in those formats. Also stripped out is other potentially important information such as VITC and (in the US) closed captioning.
The Beeb is not only well known for their standards, but for their well-written white papers on what is and isn’t acceptable – in technical, content, and grey areas. I’d suggest looking around BBC website.
