The video is decoded by your browser and never uploaded, so nothing here depends on a server — but it also means only formats your browser can play will open. A MOV with certain codecs may show a black frame even though the file is fine; if that happens, an exported still from your editor works as the input. YouTube accepts thumbnails up to 2 MB, so the JPEG option is there for when a detailed frame pushes the PNG over.
