Hey, the site's not working for me. Possibly because the source video is long?
I'm trying to create a 10-second gif starting at 71:16 of https://gifs.com/watch?v=LW6hPl6zx5Q.
I get "Your Gif could not be created at this time.". I hope you're able to fix it, gifs.com looks fantastic. If/when it works, I'll use it a lot!
