ProRes422 effecting my external monitor?
on Sep 7, 2010 at 6:59:45 pm

Hi Good Folks

I'm using an 800 x 600 Pro Res 422 seq output from FCP and trying to get my VGA external monitor to show me the canvas. I have tried all the permutations of A/V device output - here's what happens: my canvas is playing a clip which is 800 x 600 in origin. When it is not playing back, the image on my external monitor is correctly seen. When I hit playback, it shrinks vertically about 40% or so... can't figure out why! The external monitor is set to 800 x 600. This worked before with a different version of FCP. It seems to be my seq preset as non-PR presets work OK. Driving me crazy! Same thing happens with my 7" JVC crt monitor.

Any advice appreciated --

To add some information to my question: I have been researching!

I am doing a video art installation in a large gallery and I "map" my video parts onto walls or areas which need to be tweaked with distort parameters or other modifications while in place. I hook up a video projector via VGA to my laptop and finish the video in the gallery. My video projectors work fine at 800 x 600. For video projection 800 x 600 _is_ a standard video resolution. This is a problem with FCS3 as I have used this technique last year w/ FCP6. Motion 4 outputs the correct image and does QT7 & 10. I must have screwed up my sequence settings somehow? I followed another's advice and made an 800 x 600 ProRes422 seq. setting. When I drag a clip into the timeline a pop up window implies that External Video is not optimized, asks Yes or No - advice was No. FCP still says clip doesn't match my sequence settings and crushes the vertical height when playing back even if I drag a full 800 x 600 ProRes clip into my sequence, or say Yes change the seq settings to match.

Thanks for any advice... here's my seq settings -

btw, I will use the program Isadora outputting 3 video streams (AIC @ 800x600) through a Matrox TH2Go into the three projectors each set at 800x600. The Matrox only does a 2400 x 600 output on my MBP thus the resolution.
