Monitoring progressive Pal project
Hello,
I have a doubt. I´m working in a Pal progressive project and monitoring through a Sony Hvr M15E, this deck outputs video signal to a Sony Bravia KDL-32w4000 LCD via components connectors. When Avid playbacks timeline I see in Bravia monitor characteristic interleaced flickering. In the computer monitor don´t appears this problem during the playaback but I can see fields when image is stopped.1)What´s happen??
I understand Avid always works in interleaced mode regardless project type and during the playback shows fields or not depending project type.
2) Why I can´t see a real progressive image in Bravia monitor like computer monitor?Thanks!

There is no such thing as progressive PAL. You can have a progressive image stored in a PAL signal. But a PAL signal (so the signal going to a PAL monitor) will always be 620/50i.
Inside, the Avid will treat the images as being progressive. It’s the output boxes that need to interlace.In HD, it’s different, as HD has 23.976p, 24.00p and 25.00p modes, that most HD-capable monitors understand. Even then, if you use HD-SDI connections, it will be PsF.

Thanks Job,
I assume that it isn´t possible monitoring a progressive Pal signal through lcd monitor and all I can do is “Make up” artifacts in posproduction. -
Depends on your monitor. Some will convert the two fields into a progressive frame. If it’s 24p-over-PAL, it will be tricky for the monitor, as the field order changes every half second. If it’s 25p-over-PAL, it should be very easy for the monitor.
If you choose Full Frame playback mode, I think you can set that to display the progressive picture (but do mind the monitor’s refresh rate then).

I understand….. Probably I need a pro monitor…..
Very useful to me to know how LCD HD monitors interprets interleaced PAL signal.
Thanks again Job.
