I have a video track and a video track over that with a small picture, and I want to soften the edges of the picture? Can I use some gradient blur on the edges?

This is not hard to do, but it needs to be done in 2 steps. You can use the 3D DVE to create the soft edge, and then you will use the DVE to scale & position the clip.

Your routing will look like this:

If you use the DVE to scale & position, it should look something like this:

If you try to position the clip with the 3D DVE, you'll get something like this:

Hi, I tried and it is not useful at all, the solution is worse than the problem.

No one knows if there is a better method for softening edges, image or video, in the proper way?

Check the user effects. Could be that you'll find something which meets your needs.

The answer of arniepix is 2 years old.
In the meantime a lot has changed.
In my test, only the 3D DVE effect was needed:

(Minimizing the foreground with "Position Z")

If you want more (for example, round corners, borders, etc.), you can use the user effect "Triple DVE" (the preset border can be removed, and replaced by edge softness).

If elliptical or diamond dimensions are desired, the user effect "DVE with vignette" would be very helpful.

There are a few other options with Lightworks standard effects and user effects.

Do you know if there's a way to put the soft edge on only one edge?

Hello,

If you are using a user DVE effect with edge softness, it could probably be reprogrammed to allow you to set the softness of the 4 edges separately. However, the border to the other edges may look unnatural, depending on how it is programmed and what your goal is.

Without reprogramming:

Maybe a Maskable Blur User Effect will help?

As a mask generator you could for example use the "Simple 2D Shape" effect.

It's easy to forget that wipes can be used as masks and crops.

So what's going on? You first set up your DVE to achieve the position and cropping that you need, then you apply a wipe to the entire clip. The simplest way to do that is to drag the wipe effect onto the timeline and drop it. The routing in the example that I've shown looked like this, but if the wrong edge is being wiped, right click on the wipe effect in the routing display and click on "Cycle inputs". It may be simpler to do that after you've set up the wipe - that's entirely up to you.

For the wipe to work this way you will need to turn off keyframing. The screen grab above shows you exactly what you need to see, but the stopwatch icon by default will be highlighted. Click on it once to reset it to off (unhighlighted). Also it helps when setting up the wipe to increase the size of the border from 0% to maybe 2% or so. That will make the wipe edge visible. Just don't forget to reset it to zero when you're done. Also, if you want a horizontal soft edge rather than a vertical one, choose "Bar 2" instead of "Bar 1" as your wipe pattern.

[EDIT] The DVE that I've used is a custom effect. You don't need that - just use a 3D DVE. In fact if you're not going to do any other cropping apart from the one soft edge with the wipe you could even use a 2D DVE.
