Thank you for your question, but the translation is making it difficult to know if I am interpreting your question correctly.
What computer operating system are you using for your Premiere Elements 11?.
Are you referring to a "Split Screen Effect" where you can have the same person on 50% left on screen and at the same time 50% on the right of the
screen and each side is facing each other. That would be done with cropped images (fx Effects/Transform/Crop) for Video 1 and 2 and then using fx Effects/Transform/Horizontal Flip
on the Video 2 image.
What do you mean by "non-font text"? Something like cropping individual images and have each be a cropped piece to form a word?
Or do you mean creating text so that video or some image shows through the body of the text letters?
We can go into great detail on the above. But, I want to make sure of your question first. Please let us know if the above is close to your question.
If not, please give more details.
