Hard line instead of a feather.

I'm trying to get a feather on the top of a solid that has a gradient applied to it. I scaled the solid down and I applied a mask to it to feather the solid/gradient, but it's leaving a hard line at the top. I need the top to be softer and not a straight line. I think I have a step or two wrong but, I just can't figure it out. Screen shot below.

    Gutterfish - You said I did one thing, yet I didn't, and the video shows that. Sorry you're choosing to see a one sided view of things.

    I know what you did.  What you did was constrain the feather to the top of the layer just like I said you would have to.

    All I said is that you you're wasting your time trying to prove it to me.  I never accused you of lying.

    The difference between you and everyone else on this page is that you're the only who does not know WHY  you couldn't get a simple feather to work. 

    As Rick & myself and DJ all told you....your workflow is incorrect and inefficient.  

    You got this to work, yes.  But you're crummy workflow is going to cause other problems

    in the future when trying to do other things completely unrelated to masking.

    Look at me...still trying to help you out.  I must be an idiot.

     


    Inefficient means more steps to complete than is necessary and more rendering time. Sorry, your method is not what I would have chosen because it involves a lot more monkeying around than is necessary and frankly, will take longer to render. It was also inefficient because you did not understand how feathering works or take time to look at the results you were getting. We are just trying to help. To fix the problem you just repositioned the mask so that the feathering did not extend past the edge of the layer.

    If all you needed was a feathered gradient then create a solid, set the comp panel magnification factor to about 25%, use the rectangle tool to draw a mask at the bottom of your frame about 1/2 way through the center of the faded transparency you want to create and extend it beyond the bottom of the frame a sufficient distance to allow for the feathering, press the f key to reveal the feather property, set the feather, add Gradient to your layer, adjust the start position for the gradient to match the top of the feathered edge, adjust the colors.

    No scaling, no extra time calculating and rendering the scaled pixels, no other problems and done in about 2 minutes.

    An even more efficient approach would be to use the rectangle tool to draw a gradient filled rectangle exactly the size you want at the bottom of the frame, press the U key twice to reveal all modified properties of the shape layer, edit the start and end color of the gradient and the opacity of the gradient and the start and end points of the linear gradient. One layer, no extra calculations, perfect numerical control over the size of the soft edge at the bottom of the frame. I did this in under a minute by simply double-clicking the rectangle tool with a gradient fill applied, pressing the U key twice to reveal all modified properties, clicking once on the Transform Rectangle > to expand the properties and tabbing through the values and entering numbers. Then I clicked on the edit gradient tool to create my transparent gradient with a lot more control. This method also imposes almost no rendering hit to your project.

    Tells us we offered no suggestionsd, then follows our suggestion to use a trkMatt and then gives himself the credit for the correct answer.   A real pip.

    Here you go Gutterfish, more proof, just in case you want/need it.

    How about letting us know how you fixed it?  You might actually help someone with a similar issue in a way we were not able to help you.

    Nevermind. I see you applied a trkMat

    If you'd look a little deeper into that layer, you'd see that it's hidden. I TRIED applying a track matte as suggested, but it didn't work. The way I did it worked just fine. I'm about to head to class, but when I get home later tonight, I'll post how I did it .

    With the limited time I have now, I'll explain as much as I can. I made a solid and applied a gradient map to that solid. Then I scaled the solid down to the size I neeeded it for my project. After that I applied a mask to the top of my gradient/solid that I scaled down. I then selected subtract for the blending modes for my mask and set the mask to 300. Gave me a nice feather on the top which is exactly what I wanted.

    Even with the feather constrain unlocked it's going to be impossible to get a nice feather only on the top with your layer that narrow.

    The bottom is going to feather too.  If you want full opacity at the bottom and feather at the top you're going to have to increase the scale alot or constrain the feather to the top edge only.  You could do that with the mask feather tool or with another gradient layer used as a trakMat

    OK, you both have made some comments, but haven't really offered a solution. The bottom isn't going to feather too Gutterfish, because of where I applied the mask, I just want the top line to be soft and feathered instead of having a straight edge.

    I'd put a mask on a solid, feather it, and use the solid as a track matte.

    Not sure why your not getting a feather.   But the built in feather feathers all sides equally so your mask would need to be far beyond the sides and bottom of the comp so that the feather didn't show up there. 

    You're likely better served using the mask feather tool.

    It's a little weird to use.  You sort of have to pin the areas you want to hold.

    I have a habit of not providing enough information. I AM getting a feather, but it's leaving a hard line at the top. I made a little video to show what's going on. I want the top of the solid to be soft like I said previously. Also, you can turn off constrain proportions for feathering when you make a mask, so you can only do vertical or horizontal feathering.

    Your feather is HUGE - 1k in a Comp that is probably 1080 tall. It should be closer to 50.
