Yep the dip on the Canopus was the first thing I set even before connecting it. My monitor auto switches when it's fed NTSC and PAL signals. I even checked the status menu on my monitor while running the PAL footage....indeed it said "PAL 50i" I'm wondering if it's 1.Vegas 2. The ADVC100 or 3.My monitor

1. Is very unlikely- I'm using the default PAL template..I didn't change any perameters. Lower fields first is set by default- that's correct right?

2. It very well might be the ADVC100- despite the fact my NTSC signal looks fine- I see animated bars of interference when checking the calibration in "Blue Only" mode. Looks like some sort of interference eitehr affecting the ADVC100 or the s-video cable. Oddly enough I don't see the scrolling iterference bars when I'm using my cheap TRV-33 to transmit the signal to the monitor.

3. This would be the biggest nightmare for me. It would cost so much freight to send back to B&H. And how do I ever find out if it's the monitor. As I said the NTSC signals look perfect.

Have you ever heard of such a thing? Personally I've never seen anything like it...well, short of the analogy I used about CRT monitors with extremely low refresh rates. It looks absolutly identical to a low refresh rate flicker.

Try turning the lights off. If you're in the USA then the 120Hz flicker of the lights my be causing strobing with the 50Hx refresh of the monitor.
I've got the ADVC-300 and if you feed it NTSC when it's in PAL it just plain doesn't work so I doubt it's anything wrong there.
Do you have PAL footage in a PAL project? If it's NTSC footage in a PAL project then Vegas is doing an on the fly conversion which will not playout very well until it's rendered.

No it's all set right- PAL project, PAL footage. Dip switch on the ADVC100 set to PAL.

What do you mean turn off the lights? How would that physically effect my monitor? Also is the refresh on PAL footage different than NTSC if so which has a higher refresh?

I think, Bob is referring to the freq of your actual electrical supply to the lighting in the room you are viewing the PAL footage - I've never heard of this, but nonetheless a rather intriguing possibility. Here in the UK AC supply gets delivered to my house at 50hz and in the US it is 120hz. This gives a mismatch, which in turn somehow makes for a "phasing" effect .. I think I got that right. Try watching the PAL with the lights off OR during daylight . . see if you get strobing? . . If I've got Bob correct I've never heard of this BUT will store this away as a genuine issue . .interesting though - thanks Bob!

Grazie

Hi Grazie. The US mains supply is 60 Hz. The lights flicker at 120 Hz because they go bright for every positive and negative peak in the waveform. Since you get one of each peak every cycle, that's effectively double the supply frequency.

I live in Singapore, and do a lot of work with NTSC and PAL video. The only display problem we see due to supply/video frequency difference is when there is a camera involved. For example if we are using an NTSC camera indoors with (50 Hz) fluorescent lighting, there is often a pulsating effect on the NTSC video monitor that is not very pleasant. Haven't tried it the other way round though (PAL video in a 60 Hz environment) so don't know how that would look.
