View Full Version : Mask not trasparent enough

Hi
I created some masks in the corner of the frame (to hide a microphone poking in) but whatever I do, I can't get it completely transparent.
The background is red, and although there's no microphone anymore, there is a whitish rectangular which is very apparent in the forefront of the red background. I tried using the brush application to make it more transparent but no luck.
Anyone know of any good methods to tackle the problem?
Thanks
Either make a clean plate/portion of a plate and track it in or if it's only a couple frames paint it out with PS.

Yes, it's only a couple of frames, but what does PS mean?
For that matter, how do you make a clean plate and track it? I know what tracking is but that's as far as it goes.
Sorry, I'm fairly new at this.
Photoshop. Just export the two individual frames, paint the mic out, then import the frames back into your editor.

PS means Photoshop. And don't sweat the fairly new part, we all were once.
Firstly, the mask should have worked and would be the route to go, so you were right to try that as your number one solution. It should not be leaving a whiteish rectangle. I can't think of why that would happen. What is going on in the layer underneath? Maybe something is bleeding through from the layer underneath?
If is is just a couple of frames, you have a few options:
try creating a new layer and put the video on it and then, put that directly under your layer that is the main layer, drag the bottom layer as many frames as you need to the left or right to offset the time, and then mask the main layer. Even if your camera is panning, you can still do it, you just have to move the entire bottom layer a few pixels to the left or right so it lines up with the main layer.
I would try that route first, because you will have the video noise still there, and since it is so close in time to the part where the mic peeks through, the lighting will be pretty close, if not identicle.
if that doesnt work, you can try the clone stamp for just those frames, and then put a new layer of main video on top with the left brackety looking thingy that indicates where a track becomes visible drug just to the right for those few frames.
Or, you can export a frame of video and open it in Photoshop, use the clone tool and healing brush to fix it, put that new still on top, mask the still so that only the llittle part you need is shown, and then end it when the mic is out of frame again. If the shot is moving, you'll have to motion track just as tmnt said.
I would use the Photoshop method as a last case scenerio only because it would require the most work, and would also require the most skill to blend in with the footage.

Thanks, Matt.
This stuff is a little advanced for me, but I'll give it my best shot.
