  • PNG Transparency fine in RT, but renders like crap.

    Posted by Cory Caplan on June 23, 2009 at 1:09 am

    I have some absurdly small disclaim text which is using a PNG, and looks just fine in RT, but rendered in Prores422 (both HQ and non) looks like the edges go to 1-bit alpha. Or at least not “right”

    Any ideas?

    Could be the font. Where are you viewing this?

    It’s arial narrow, but that’s not so much a concern, it’s a rasterized “graphic” …does the font matter so much? I’m having a problem with a layer above it too, an animated qt.

    I just don’t understand how it’s processing the alpha differently in RT vs render SO DRASTICALLY. Might be a new QT bug or something, don’t know if anybody else is experiencing something similar.

    Tracks are like this:

    >V4 – Disclaimer PNG
    >V3 – QT Animation Codec w/ Alpha
    >V2 – Transparent PNG blue letterbox
    >V1 – Video/Solid PNG

    Time to panic.

    What format is this? Are you looking at a rendered output in playback on a video monitor? You can’t assess an interlaced format on a computer monitor, especially not with text that crappy.

    All the best,

    Yes, the results are the same on my Aja LHE. As a matter of fact, it plays perfectly fine on a monitor unrendered, and then, once rendered looks on the monitor like it does on the screen.

    Now I’m getting nervous…

    I only have this problem if I render in Prores422. (No difference between HQ ON/OFF)

    This must be a recent development or somebody surely would have noticed this, yes? Kind of a big deal..

    If Avid DV50 can do it, surely Prores can?

    Build your comp in Motion or Live Type.

    Hi Cory,
    Have a look in the Browser about the Field Order.
    I don’t know why many times they show up as Interlaced spoiling the rendering.

    Thanks for the suggestions.

    the PNG isn’t interlaced, and clearly isn’t the problem, as I can change the codec, and it works fine.

    As for the recommendation to do it in Motion on AE, yeah, I had to move a lot of the project to AE, but I still need to do the name/web super and the disclaim in FCP because of the 80 or so different versions I have to generate. Luckily (?) I can do the workaround with animation codec or whatever, if I don’t find a fix.

    This is clearly a Prores glitch..

    [Cory Caplan] “the PNG isn’t interlaced, and clearly isn’t the problem, as I can change the codec, and it works fine.”

    Cory, that could actually very well be the problem.

    being interlaced doesn’t matter. changing the codec doesn’t matter.

    in some instances not setting a field order of either a sequence or an item
    can cause this very problem your having.
