I tried to save one of the "gifs" to share with a friend and was quite upset that I found myself with a png. Interesting technique. Do you think this was done to have better quality animated images? GIF compression isn't amazing (relative to WebM at least)
- capitainenemo 5y agoI mean, they could have used APNG at this point. https://caniuse.com/apng https://caniuse.com/apng Doesn't compress stuff like that super well but no worse than a sequence of PNGs. I feel if you're gonna use JS animation anyway, you could just use 2 jpegs, one for masking and a canvas. Hm. Webp is doing darn well these days too. https://caniuse.com/webp https://caniuse.com/webp Avif isn't an option yet.
- dylan604 5y agoProbably more along the line of they have some library that uses PNG sequences. Maybe even as simple as a slideshow with short durations. It's a newsy site. They don't have a lot of control over what their CMS/publishing platform can do. Someone probably had a clever idea on how to use something existing in a way not envisioned when created.
- jameshart 5y agoVery gratified they didn’t just post these as rendered gifs. Imagine the social media scare you could generate in a year or so after everyone has forgotten about this eruption by sharing a graphics.reuters.com URL for one of these animations that appears to show a satellite image sequence of a massive mushroom cloud obliterating the Korean Peninsula or the Sinai with a breathless ‘LOOK WHAT REUTERS JUST REPORTED!!!’ caption. It’s really important for reputable sources posting images to think about the fake news potential of them getting shared out of context.
