EffectsLab isn't really designed for this type of compositing. CompositeLab gives you much greater control and makes that type of effect easier.

But still, check out this tutorial by JT9 which does explain a way to clone in EffectsLab.

1. import the video.

2. trim it

3. delete the part u dont want add the part u do.

Your footage is brighter on the un-masked portion because of what is known as the "blend method". Any footage that is imported into EffectsLab using the "Import media" function will default to the "Screen" blend method, which results in the top layer appearing brighter.

As EffectsLab is not intended for complex compositing, any additional media (media imported using the import media function) can only make use of an "Add" or "Screen" blend method; both of which have a similar affect on your footage, making darker pixels translucent, and brighter pixels appear luminescent.

For this reason, Axeman suggests CompositeLab for this kind of task. The method JT9 describes in his tutorial, allows you to use a single piece of footage, eliminating the need to import any additional footage into the media browser.

Slicing this footage creates the required second layer on the timeline, and allows you to proceed as you would normally, using the blend method "Normal"". A "normal" blend method prevents the footage from becoming luminescent, or transparent.

In your case, if you copy the mask from the masked layer, and paste it on the un-masked layer, then select to invert the mask once again, the footage should no longer appear brighter then desired.

By copying the mask from the finished layer, you are copying any key frames that may have been created throughout the project. This is necessary, as the inverted mask you create on the other layer, must match the first masked layer for a seamless blend.

I hope that is clear.

Sorry I missed this thread. But Wizard got it covered. If you follow my tutorial correctly and follow Wizard's post it should come out fine. But if you want really good results for cloning methods use Compositelab or Visionlab.

Cheers.

am i getting this right.
1. Import media
2. Trim clip
3. overlay the 2nd clip ontop of the 1st.
4. create mask and invert

Well, thank you for the illustrations. I now believe I know where you are running into some of your complications. It may be best to start at the beginning, and go over the main concept of cloning, as I believe there may be some confusion on the matter.

What you are attempting in EffectsLab is essentially split screen cloning. In a basic split screen cloning example, it is necessary to record two separate actions, at different points in time. One action being on one side of the screen, and another action taking place on the other side of the screen. When I say screen, I am referring to the EffectsLab canvas.

You can film these two actions in different takes, or by simply filming continuously, and then separating them at a later point. The important thing to note is that you can not move the camera. It is also a good idea to watch out for differences in lighting when filming, for consistency concerns.

Once you have filmed what the "clones" are doing (acted out both of your parts), and have imported the clip(s) into EffectsLab, you now have to combine the two separate actions into one seamless shot, to make it appear as if there are two individuals standing next to one another, interacting with same environment.

This is where the mask comes in; once the two layers are directly over lapped, place a mask on the appropriate side of the top layer (the side without your actor). Or, you can place the mask over your actor, then animate the mask to follow the actors movements (if necessary), then invert the mask so that it is no longer removing the actor; some find this easier, but it may be confusing to some.

This effectively removes the area the mask covers, revealing the layer beneath; revealing your other clone. I noticed in one of your illustrations that you had moved the quad off center (moved the video to the right). This has the same affect as moving the camera, and makes the footage not line up.

Be sure that the video's stay perfectly aligned with the canvas, to avoid discrepancies. The background must be completely lined up for the effect to succeed. Once you have become familiar with the concept of cloning, you can begin to consider things such as clone interaction, or problems regarding shadows, etc.

Additionally, I noticed from the illustrations, that once you over lapped your footage, it became luminescent. This, to me, says that you are beginning your project as a blank time line, and then importing your footage using the import media function.

As I said above, this will result in your footage using a "Screen" blend method by default, which will make your footage brighter when layered on top of other footage. To avoid this, begin a new project by selecting "Select movie" from the welcome screen that appears when you start the program. Or, select "File">"New project - select movie...".

If you run into any complications, or would like me to explain a specific point in more detail, I would be more than happy to give it a try. Cloning can be quite the undertaking when you are beginning, so we would understand if you find you have more questions.

Good luck.
Wizard.
