So you hear it too. I think it has become a worldwide standard reply.
Before jumping splices it was colour grading: everything had to be
It seems that the German industry, quite correctly, sets very high
technical standards, and programmers, distributors, producers, and
everyone else in the line finds they are forced to live by them. There
are even people who earn their living as finishing agents, who undertake
to supervise telecine mastering up to German standards. The rest of us
live in fear of faxes in a foreign language that we are told are
technical rejection reports.
Of course we should all aim for the highest possible standards: who
would dare argue for less? If your product is OK, why would you argue
away your advantage?: if your product fails to meet the standard, who'll
take you seriously?
But there's a good and a not-so-good way to apply standards:-
If it takes a frame-by-frame analysis on telecine to detect frame jumps,
the response, ideally, shoud be: "hey, there's a problem that should be
tackled before it gets worse". If it isn't tackled, probably the next
production will have a bigger problem that can be seen at normal speed,
and rejected totally. That way, the viewing public sees perfectly good
technical standards, the industry aims for better than that, and we
don't waste innumerable resources chasing invisible (and all to often
Does anyone have a simple way of explaining this two-teir QC approach
(green=OK, yellow=OK this time but check your equipment, red=reject this
time) to non-technical people? Auf Deutsch? It's a real problem, and
not just with distorted splices.
Comments, arguments, anyone?
