How to Prototype a Video Progress Bar with Image Previews?

Has anyone come across a tutorial or know how to prototype a video progress bar similar to Netflix or Youtube, where dragging the bar shows an image preview of the video and as you drag the image changes to a preview matching the video time stamp? I’m looking for ideas on creating an interactive slider that displays images as you drag. I’ve found tutorials on sliders with changing numbers, but nothing so far that incorporates image previews. Any suggestions? Thanks!
