This is a good opportunity for me to share this. Facebook tends to refresh the feed if I go idle too long or just to mess with me, making me lose the source entirely so I can't find it again.
I was making a gif of this Snowy trying to grab its dinner, but just getting a mouth full of leaves instead. The look of disappointment into the camera was great. But since I lost the source I didn't feature it.
Since it is related to today's photo and I don't want it to go to waste, here it is.
CloudConvert is the easiest I use. It is good if the MP4 is about 10 seconds or less. You can select codec.and frame rate, but that's about it. Any longer than that and I have to cut the frames to get it to around 10MB, there seems to be a cap on .World upload size.
EZgif has more features like start and stop point, resize, reduce file size, etc
Nothing that advanced. There's just an occasional video worth sharing, but it's on Facebook, which everyone here is pretty rightly opposed to visiting, so I convert it to an image so I can upload it here.
