I have a Motion Designer toolkit and I want the black paintstroke to be a mask to one of my video layers. I can not use mask because the black needs to be opaque? if I key it, the entire graphic goes away.
I'm not exactly sure what you're saying, but here's a few thoughts:
- first, did you set the alpha channel of your DJ animation? Right-click the event, select Properties (at bottom of list), select Media tab, then set Alpha Channel (near bottom) to "Straight (unmatted)".
- second, if the color of the DJ animation doesn't work right for a mask (black when you want white), then try throwing an "Invert" video FX on it to reverse the colors. If you just need to raise or lower the black/white levels (not black/white enough), then I think a "Levels" video FX will help that.
- third, if the DJ animation doesn't have an alpha channel built into it, I think you'll have to a "Mask Generator" video FX on it to construct an alpha channel based on that event's overall luminance, or the brightness of the individual red/blue/green channels.
I will review the tutorials but tis is specifically wheat I am trying to do:
There is a black (with transparency) paint stroke that I want to use for layer 4 of video. I drag the brush to layer 3 and apply mask mode for this layer. I see, I think that I have to threshold it so that the black becomes white and then I can use the mask, so that layer 4 shows as the DJ stroke.
For starters, you have set the alpha at premultiplied and if it is DJ media it needs to be Straight(unmatted). Then add the invert VFX to the black and white clip. Slide the blend slider all the way to the right.
You should be good to go with the rest of what you are showing.
There is something that I am not seeing then. Can you upload to somewhere or email me so that I can get a couple of seconds of the DJ piece you are using? Something is slipping through the cracks. You may need to use a mask generator, but for this I normally do not need to.
