    Anton's right, broadcast black usually looks very bright on a computer screen, but looks right on a broadcast monitor.

    please ignore the preview monitor behaviour, the milkiness on preview monitor is a focus/non focus overlay issue and has nothing to do with the result of the video or external monitor, trust your waveform monitor for blacks, Tektronix are great, I could not work without them

    do not trust the preview monitors for colour calibration of anything

    in your case, it sounds like you need to adjust your TV or replace it, not all TV can display true black (Sony PVM or BVM usually can)

    Plasma and LCD of any kind can't display true black unless you get the broadscast reference versions starting at $20k

    Here are the grabs...
    Screens with nr. 1 are when the right window is selected and nr.2 are with the left selected.

    Hope this helps..

    Can you post a screen grab of your time line with the wave form monitor open and selection set to ire?
    Cti on empty space .

    This is the first time I hear if this. Mind you that there are users here that produce Pal for broadcast which don't have this problem.

    First of all, thanks for the help.

    I am using the PAL DV50i 16:9 48Khz project.
    I'm not using an external monitor.
    While switching between 2 preview monitors (PLR/REC), while the right one is NOT selected I can clearly see the following:

    - timeline blank = 'grey'
    - black (0,0,0) matt on the timeline = 'black'
    - vitascene transition (fade in black) on the (0,0,0,) matt = 'grey' while transition is running and black from where it finishes

    At first I noticed when I leave a timeline blank, that it appears milky grey on TV.
    Then I found out that I can get a pure black on the TV if I put a black color matt - but only when pulled to the bottom (-7.3 IRE).
    I can see it in Edius. When I click on the right preview monitor- black is black, but when I click on the left- the right one goes to grey.
    But when I get a -7.3 black color matt on it, it stays black all the time.

    I haven't read anybody using this so I must me doing something wrong.
    I am aware that this -7.3 IRE is illegal when going to broadcast. My work won't go to TV stations, but how do they get that nice blacks.
    It dont' see movies having that kind of milky black. :-/

    I know I am missing something, so any information is more than welcome.

    Lately I have been using vitascene transitons and when using them to fade to black, I get that fade to 'grey'.

    This is freaking me out... I would like to have blacks as black as the TV can make them, so please HIT ON ME!
    Ok I have tried pal presets for the test and I can tell you that edius export blacks at zero from a Pal projects it makes no difference if I use the empty timeline space or a matte.

    So I think there is something wrong at your end. Maybe you are using a Ntsc preset with 7.5 for monitoring?

    Otherwise, EDIUS will treat all black areas with a "legal" 15, 15, 15 colour.
    If I am not wrong Pal is always 0 (zero)
    Ntsc has the option to go 0 or 7.5
    I can tell you that at 7.5 edius threats an empty space as 7.5 for out and 0 to digital. (that is with canopus hardware because the 7.5 is for analog out only)

    Where it gets skecthy is the option under ohci to go 7.5 for monitoring. (skecthy because ohci is digital)
    I could not find in the documentation if in ohci the 7.5 is brought down to zero when doing an export or if you have to adjust it to 0.
    I measured it and I found that it does but I advice people to bring it down to 0 because I have not seen what the "official" stands on this is and if the to 0 bring down happens on all export modules.

    I have been doing that, but now when using Vitascene's transitions it dips to 'grey' even if the matt is under.

    I thought my way of putting the matt under is not the right way of getting the blacks, since I heard no body talking about it.

    Any way of making Vitascene to dip to pure black?
