HD Waveform via downconversion

Anyone using a downconverted signal to monitor waveform? (as an aid to exposure)

Has it worked?

I did it once with an F900 shooting 60i into a Textronix WFM90. I just used the luminance. It was O.K. for checking levels because I checked the level of the

color bars with it. It just looked a little funky though - like it was coming from a non timebased source. :)

Why do you need to downconvert your signal to view it on a waveform monitor?

I just took the Y component out of the back of the monitor loop thru. Now that I think of it, I guess there was no downcoversion.

Is not SDI to components a "down conversion" ?

I consider it is.

I believe the F900 has hi def component outputs. I consider a down conversion something like hi def to std def. I don't think SDI hi def to component hi def is a down conversion although it does degrade the picture slightly. :)

Let me rephrase the question,

TO SAVE MONEY have I got your attention:) is anyone regularly using a downconverted HDSDI signal ie SDI (not HDSDI) into a cheap SDI waveform?

Saves renting buying an expensive HDSDI waveform.

For use for monitoring exposure only, no vector scope use.
