PAL Broadcast Colours

Hello All,

I am trying to get my head around the best working practice for PAL.

Been searching the web and finding loads of stuff but a lot of the information is far too in depth or not in depth enough for editing guidelines.

What is the best practice for working in PAL land.

Happy that colour clamps are not a requirement for web media but how about PAL DVD as the destination format or is it a non issue for DVD as well?

Should I be using the broadcast filter FX on a video bus and unchecking the 7.5 IRE setup option (am I right in saying this is for NTSC whilst PAL is 0 IRE) and work from there?

Any guideance appreciated.

The use of broadcast limited colors only is necessary if your product is meant for broadcasting.

PAL has no setup so leave the 7.5 checkbox unchecked.

Just been down this path myslef!

The legal range for video that's going out to TVs or broadcast is from 16:16:16 to 235:235:235.

VVs generated media will exceed these limits which MAY cause problems. You also have to consider possible illegal colors also but VV does throw up a warning.

Apart from the last one I found the simplest thing is to ignore the issue and apply the Broadcast Color filter to the video bus, much easier than trying to fiddle with each and every clip. Even captured video from my camera and other bits of gear seems to exceed the allowed levels.

I do find if I'm coming out of DVD players the issue is not quite as critical, particularly if they are feeding RGB to the TV or monitor.

Hope this helps.

Marco,
not entirely true. You can drive a TV nuts feeding it blacks below sync level.

Believe me I've done it and spent ages trying to work out what the hell was wrong, answer was black generated media at 0:0:0 as VV generates by default. It will not spin all TVs out so be very careful.
