You should convert all your gifs to videos. Otherwise a lot of people will drop cause their browsers crash. And don't think about people from mobile devices. Sometimes they're about 50% of the traffic.
I completely agree. This was a struggle for me -- I wanted to show off features on the homepage, but adding a Gif slideshow added a crap ton of load to the page.
I wanted to create a video, but my video editing skills are pretty poor and I wanted the experience to be great (even my gifs have a few bugs in them if you look closely). I'll work on this for sure.
