I think I'm drowning in an inch of water: do you remember the union of two images with a gradient? (The web is full of tutorials, example



)
I'm trying to do this in after effects, or rather, having two video / two compositions I would like to merge them into one, the attached picture will be much more clarifying what I mean.

Not having the tools of photoshop how can I get it?
Thanks so much!

The attached picture I have worked in two seconds (with photoshop! I can not do it in AE), is not very precise and quite unpleasant, however I would like to get a clean job, with a real shade, avoiding the horrible line is formed in the middle.



PS For made attached picture I used two different frames found on youtube.


-Sorry for my little english-

Hi Gigi,

*Position your two video layers side by side in After effects. You need to make sure that there is plenty of overlap to accommodate the size of gradient you want.
*In the timeline/layer view select the layer on top.
*Click the Rectangle tool in the tool panel at the top of the UI (it should be just to the left of the Pen tool)
*Then click and drag a big box around your video in the composition view to create a mask that completely covers it with plenty of extra space on all sides except the side where you want the gradient. On this side, position the mask edge at the center of where the gradient should be.
*You will now see in the layer view, that the top layer has expanded and now shows “Mask 1”. Expand mask 1 then increase “Mask feather” until you get the gradient width needed.
*You might see some unwanted transparency on some of the other sides with a really big feather, so just increase the mask size in those areas to compensate.
