Vectorscope 100% PAL
Hi There,
Just wondering if it’s possible to set the vectorscope to 100% instead of 75% in PAL. Can’t find it anywhere in Prefs.
Worked out they are set to 75% by default and the majority of broadcasters are wanting material with a 100% reference for PAL programmes.Would be nice if they actually defaulted to the proper PAL bars – in bars and tone>more bars and signals – could be confusing for a young editor.
Thanks,

That is not right. The vectorscope is adjusted to show 75% color bars in PAL because 100% bars in PAL are ILEGALl and you can not use an ilegal signal to adjust nothing.
The UER color bars are 75% intensity and 100% saturation, except for the White bar that is 100% intensity and 0% saturation (because is white, so it have not chroma information). Some times are used some 90% bars, but never 100%.

In a world of digital video, bars and tone are irrelevant. We only put them on the tape so that archaic international delivery specs are satisfied. I recently delivered HDCam masters to a Dutch distributor who complained that I had put the FCP default bars and -20db tone.
I invited them to drop any bars they liked onto the head of the tape once they had made the 29.97 HDCam master for US sales. They seemed horrified that I didn’t care less about what they did with reference on my master.

That’s right if you just keep in the digital domaine. Not if you go to the analog. The international delivery specs they still being valid in the 99% of the world. Had you ever experienced what happens when you broadcast a signal with ilegal levels?

Yes. I started as a telecine op, grading live to air in 1976. My point is that bars & tone on a digital tape are archaic as there is no playback calibration required. If they are dubbed to analog tapes then bars & tone can be inserted on the analog dub.

Your right Michael, the bars can be set when dubbing or can not set at all as is happening today in the most of the cases. The most part of the people don’t care about bars. The most of the people today they don’t know why they are for.But I’m still thinking that is a good habit for video editors to set proper bar, mostly because if you don’t set them in the beginning, nobody will do it . The people of our generation (I started a bit later than you, in 1982) should try to keep that habit mostly because the most of the stuff that is broadcasted all around the world, still being analog (dubbing to betacam or analoge output from digital desks), and without bars there is not way to set your player properly.
