Video decoding is resource intensive. We're used to it, we have hardware acceleration for some of it, but spewing something around 52 million pixels every second from a highly compressed data source is not cheap. I'm not sure how both compare, but small LLM models are not that costly to run if you don't factor their creation in.
All they’d need to do is generate thumbnails for every period on video load. Make that period adjustable. Might take a few extra seconds to load a video. Make it off by default if they’re worried about the performance hit.
There are other desktop video players that make this work.
