  crt Monitor for multibridge extreme

  Posted by Miles Blow on February 5, 2007 at 3:17 am

  Hi guys
  The multibridge can only do analogue down conversion monitoring with interlaced hd video..Right? So how would you do colour corection etc in 24p? We have got the dell 24″ set up but we want to also see our video on a crt monitor. Would you just have to chuck the progressive footage into a interlaced project and render it?

  Would this happen if using a proper hd sdi crt monitor like a jvc dt-v1710?

  thanks
  Miles

  Hi,

  If you use a 1080p23.98 clip, it has to be in a 1080p23.98->59.94 easy setup timeline. This pulls down the video to 59.94 before down converting to NTSC. your footage remains untouched but the down converted output will be interlaced.

  Hey It works great!!!! Am I the only one who didn’t know this?

  We have rended all our footage in 24 frames per sec hd mjpeg and it plays back perfectly in a 23.98 progressive project in premiere, we dont even need to re-render anything! Cool.

  Also is there any benifit or disadvantage to previewing hd in either ntsc or palon a crt monitor? We normally use pal(australia) But Our sony crt monitor only lets us adjust phase when it recieves an ntsc signal(its always been a a bit greenish)….so i think we will just set the decklink down conversion to output to ntsc. That way colour looks great!

  Well.. If your target is PAL than it has to look good in PAL. Actually the Phase adj. on NTSC Monitors is part of The “NTSC problem” Your Monitor have to be set up such way that you do not need ANY adjustment on it. I mean everything is in preset. As CRT Monitors get older the “green thing” comes about and you need to calibrate it with some test gear. You really can not do Color Correction without having a known good sort of reference Monitor.

  Hi, well our target isnt pal I dont think there is pal and ntsc in hd…in any case we are really offlineing in hd mjpeg…… the final edit will be in 3k..well hopefully. Yeah the monitor we have has actually always been abit greenish ever since we bought it brand new..yes we need to get it calibrated.
