add animated gif to jpg - Match layer across frames
I am new to PS (obviously), and I want to add an animated transparent gif to a static jpg photo so that the animation plays over the static background. I watched a non-Adobe YT tutorial and followed the steps but, when I tried to "Match layer across frames," none of the animation frames was populated by the selected jpg frame - they all stayed transparent except for the small animation itself and, when played, the selected frame was the only frame that showed the jpg and the static animation for that frame - the other frames were just the animation and the transparent (see attached screen capture.)
I am posting this question in the hope that someone with more expertise will be able to point out to me what I am doing wrong, or what I should be doing that I'm not.
Thank you in advance for your help!
