  • image won’t show up under another keyed green screen image

    Posted by Phillip Enriquez on April 15, 2009 at 7:26 pm

    Hello all. So I’m working with a green screen image sequence that I’ve keyed. Basically I’ve been trying to layer the keyed images on top of each other but the images aren’t showing up when placed underneath each other. I’m wondering if it has something to do with working with keyed images instead of movs and/or the format of the images being tiff files. Is there some way around this?

    I’ve provided a link below where you can download a zip of the ae file w/the keyed images. Thanks in advance!

    -Phillip

    you need to apply the keying effects directly to the footage that you want to key. then each will key separately and you can over lap them.

    by using an adjustment layer, the keying effect can only work with the visible layer… in this case the top most image.

    select your adjustment layer and hit ‘uu’ (that 2 letter ‘u’s) to reveal all modified properties in the time line. select all the modified properties (hold shift while selecting them). then select all of your tiff sequences and paste. this should paste the effects and settings from your adjustment layer onto all the tiff sequences, and you should see them layered on top of each other.

    Thank you so much Mr. Kevin Camp! Applying the keying effects directly to the footage instead of solely on an adjustment layer did the trick!

    Hey Mr. Kevin Camp would you be so kind as to give me your input on my other problem I have posted at the link below?

    i was able to render it out with the bezier mask… i didn’t change anything, just opened it up and rendered it out as lossless with alpha (best render settings), imported it back in and it looks just like the footage with the mask…

    did you try a reboot? sometimes ae just behaves badly and a reboot sets it straight…

    I believe Mr. Kevin Camp that you just helped me figure out what I was doing incorrectly. You see I’ve been rendering lossless with alpha UNMATTED. So I just rendered out lossless with alpha MATTED and that did the trick!

    2 for 2 for you today Mr. Kevin Camp! You are simply amazing and thank you again for everything!

    Genuinely,
    Phillip

    One last thing…sorry but you probably guessed by now that I’m a newbie to this. So I’ve put the rendered mask onto a clean plate but the mask appears darker than the plate. I’ve tried color correcting and adjusting levels but can’t seem to get the shades of the mask and plate to match. Is this a matter of just continually messing with levels and/or color correcting until I get it right? Or is there a trick to this?

    Thanks in advance!

    Genuinely,
    Phillip

    I’m not Mr.Camp nor have I looked directly at your project file, but if i understand correctly, you have rendered some keyed footage with alpha, and now want to put it on a clean background plate, but the colors/exposure/looks aren’t matching?

    It could be to do with the codec you rendered the footage in – for example, H2.64 has a gamma shift that makes things a bit lighter and washed out, I think mpg4 darkens a bit, etc. So if you are lining up your render with another plate shot at the same time, you might expect them to match but find that they don’t.

    One option is to use the comp in which you keyed the footage on top of the plate, rather than a render of that comp.
    Otherwise, yeah, you may need to color correct it manually… there are a few tricks that may help – if you push the exposure way up using the Adjust Exposure controls in the Comp viewer you can find the place where black first appears, and then match the two clips black levels like that. Also looking at individual color channels can help too (also in the comp viewer, the RGB circles icon, you can select a single channel).

    Hello Mr. Stuart Elith. Sorry for the confusion but it seems that you’ve summarized two separate problems I’m having into one issue. The problem I had with overlaying keyed footage on top of each other has been solved. Mr. Camp suggested that I apply the keying effects directly to the footage instead of an adjustment layer.

    The problem I’m still having that needs resolving has to do with trying to get a rendered mask to match a plate in terms of colors/exposure/looks. I’m guessing that your suggestions still stand regardless of whether I’m working with a masked or keyed footage. Here’s the link to the problem at hand:

    Thanks for your input Mr. Stuart Elith and should you have any other suggestions I’m definitely all for it!

    Genuinely,
    Phillip
