Sony Broadcast Safe FX

Sorry for setting up a new thread for this relatively trivial enquiry; I was considering to put it as a continuation of one of the other threads, but finally decided to set up a new thread of its own, counting more people will see it.

Some of you may remember difficulties I've had with the DVD menu button lettering masks, and particularly their colors - what looked great when previewing from DVDA on both my PC screen and the secondary DVI-HDMI, full HD 50" plasma - turned out awful after I burned the DVD, and played it back from high-end DVD player, hooked up to also not so bad, but SD, 42" plasma.

Well, to avoid having to burn a DVD each time I make changes, I thought that my new field/studio monitor (the 11" Manhattan LCD) could be connected using S-video, and thus emulating the "worst watching scenario". And so I did, and I have a direct monitoring of everything in SD.

But one thing worries/ surprises me: even on that monitor, there is NO difference whether I turn the broadcast Safe FX on or off !!!

The filter action IS visible on the scopes, though, which leads me to not quite trust the monitor as my SD monitoring device in both Vegas and DVDA, which is a pity...

Any comments on why this may be?

could be there's no visual difference in what you're doing. If it's a LCD monitor odds are it's not limited to 16-255 so it will look good, just like your PC screen. For a "worst case" scenario, you'd want a SD TV with RCA cables. Make sure there's nothing special about the set or else it could be correcting things for you. If there is a visual difference it should be showing up anyway (even on your PC).

but you can also use a DVDRW (+ or -) to make test disc's. Works great.

Your monitor is probably incapable of displaying the full legal range of video. Try feeding it bars with pluge to see this.
So it's already doing what the BC Fx does, clipping super whites and blacks.

S-Video provides more chroma bandwidth than composite i.e. pictures look better using it, especially graphics. If you really want to see how bad it can look use composite and use a CRT. LCDs can hide a lot of things.

If monitoring SD, I'm a huge fan of the CRT (especially a broadcast CRT and not consumer). LCDs have to scale the image and this introduces artifacs that don't exist in the original. Same thing with deinterlacing (there may be deinterlacing artifacts that don't exist in the original). And color on the cheaper stuff is wacky.

The LCD monitor may be clipping off illegal values. This can be a bad thing, as CRTs don't do this and will show a different image. You should clip the illegal values off anyays... color curves presets here:
