Hey vichug, no… not my gifs. They are the creations of David Ope. He does great work. Not sure how he does it but I’m pretty sure any video clip can be converted to a gif so it’s mostly a matter of getting the first and last frames linked and keeping the file size down.
To convert video to gif, Photoshop has an ‘import video to layers’ option and a ‘timeline’ window for editing.
