Hi,
Thanks for reaching out to us.
Photoshop elements is a photo editor and you can not process videos here.
And, yes, you can create GIF using images here as follows:
Save a file in GIF format
Specify a filename and location, and choose CompuServe GIF Format from the format list.
Your image is saved as a copy in the specified directory (unless it's already in indexed-color mode).
If you are creating an animated GIF, select the Layers As Frames option. Each layer in the final file will play as a single frame in the animated GIF.
Click Save. If your original image is RGB, the Indexed Color dialog box appears.
If necessary, specify indexed color options in the Indexed Color dialog box and click OK.
In the GIF Options dialog box, select a row order for the GIF file and click OK:
NormalDisplays the image in a browser only when the image is fully downloaded. InterlacedDisplays a series of low-resolution versions of the image while the full image file is downloaded to the browser. Interlacing can make downloading time seem shorter and assures viewers that downloading is in progress. However, interlacing also increases file size
Thanks,
Arshla
