The whole licensing thing vaguely reminds me of the MP3 patent. With the format becoming widely-used in both players and encoders, then Fraunhofer comes to demand and collect licensing fees and royalties. Forcing companies at the time either to cough up for it, or try to develop their own replacement.
Yeah, it was a mess. CompuServe themselves got sued for using a compression algorithm that they didn’t know had been patented. They created GIF based on a published academic paper about the LZW compression algorithm, and the paper didn’t mention that the author was trying to patent it. Once then-owner (Unisys) found out GIF used their algorithm, they wanted licensing fees for all subsequent uses of GIFs, except display on websites of GIFs that had been made using licensed software. Unisys’s fees were very reasonable for software licensing fees at the time, but after GIF had been free for so long and was embedded in everything, it was basically legalized extortion. “Give us money or your entire graphics library will become unreadable.”
Since CompuServe had to pay Unisys after that for licensing their own GIF format, they stopped making GIF-capable viewers available except to their own paying ISP customers, and wouldn’t allow third party developers to support it without paying them and Unisys. (Not that there weren’t millions of cracked copies of CompuShow available for the asking, and all sorts of other freeware that just wasn’t licensed.) PNG was created entirely because of that. JPG also became popular in large part because of that too, although its superiority at handling screencaps was probably a bigger factor there. Also uncompressed GIF (it still compressed the palette to 256 colors and the lines to line lengths), which is supported but never caught on for obvious reasons. For the most part the format just remained widely “pirated” until the last of the international patents expired.
must be outdated. I can see the frames but it’s not animating.
@Vinyl Fluff
Yeah I loved Equum’s so much I had to give them a try. Also, I use most of his (and some of mine) as wallpapers using VideoWallpaper. lots of supported file types and neat features like playlists and loop duration.
gfycat saves both the gif and converts to a WebM version
Unfortunately you would have to link though…
Hey, nice work on these, BTW. I set one of the Luna ones as an image in my profile the other day simply because I loved it so much. It took an already awesome image, and made it even better.
Yeah, as I said earlier, the file sizes are completely understandable given the image size and complexity of the animation. It was a “man, it would be nice if they could be smaller without affecting the quality” thing. Pretty much because I’d love to post these in a few places, but it would just kill the bandwidth for so many people.
They said they talked to the developer on Twitter and the developer is unable to fix it due to a Chrome Update…
Here you go
For some reason the extension isn’t working for me… it used to…
Edited
I must not have that chrome plugin XD
But of course gifs are still the most widely used… even though they are limited to 256 colors… sigh
Edited
APNGs are png animations… but the support is very limited
If you’re using Chrome and aren’t using an extension that allows you to view APNGs, then these will just show the first frame of the animation
Really gif is the way to go… it’s extremely inefficient, but… that’s really your only option
You could upload the gif to Gfycat and link to it in the deviantart description… but that’s really the only way you can do WebM
So the best I can do at the moment is try to keep them as close to 25Mbs as I can (typical upload size limit).
Thanks!
Beat headphones, not the best but pretty good
Well, they were over 400 dollars… extremely overpriced for the quality.. I got the studio kind or whatever…
I mean they sound good, but not over 400 dollars good…
An equally-important piece in the equation for distinguishing higher bitrates is high enough quality gear, as with lower-end speakers/headphones you’re not going to get the clarity required for it. But I’m assuming we’re working with higher-quality gear to begin with, and not stuff like crappy OEM USB-powered speakers or iPod earbuds.
Yeah, unless you’re under 13 years old then most likely you can’t hear above 20khz
At 20 years old that number is about 17khz
50 years old 12-13khz
90 years old 4khz
Okay, I think I made the point
Anyway, I can only tell up to about a 192 mp3, 256 if I realllllllly listen.. after that, it’s extremely hard
Edited
I’m fine with files taking up say, 14MB each. Taking up 35MB each and running by battery down 30% faster? No thanks.
As far as frequencies go, human hearing maxes out at 20khz. for all but a few exceptional individuals. And many are lower than that. Plus our top-end lowers as we age.
Edited
I still don’t understand why people like to convert to mp3 so much more than mp4
I understand posting the mp3 version online, since it might cause problems with some people… but if your device supports mp4 then why not just use mp4?
Eh, at 320 I guess it doesn’t matter too much
I did look at a spectrogram with a 320 mp3 versus a 320 mp4 and the only difference was about 0.5khz more at the top and the sound levels were more accurate (maybe LAME just turns down the sound by like -1db or something)?
a 320 mp4 goes up to about 24khz in a spectrogram, while a 320 mp3 only goes up to about 21.5 or so
Plenty, I can only hear up to about 16.5khz
I’ve got an MP3 player with a microSD slot, and a 64GB microSD card. I’ve got my entire music collection on it, and still have a ton of room to spare.
By no means does it sound good, but it’s at least listenable to some extent
The guitar sounds really off but besides that I don’t think it’s terrible
Although, the whole song sounds altered… just “off” Apple’s AAC is better at keeping that intact… but at really low bit rates it kind of “skips” and there’s other glitches.. I forgot what but I just prefer Nero if the bit rate is going to be 40 or lower
Also with Apple you can only go down to 32… Nero you can go all the way down to 12 (but it sounds extremely choppy at that amount… if you look at a spectrogram… oh boy..

I’m stupid…
Well, I tend to like Apple’s version of their AAC but at lower bit rates (I mean really low bit rates… 40kbps and lower) I tend to like Nero’s better because it’s less glitchy…
Apple’s AAC starts to become really glitchy below 48kbps
Of course there’s really no reason you should need to compress that much… Although, I was able to go down to 22 with it at least sounding somewhat listenable… When I tried 21 it cut the frequency down about 3khz… that’s just how the codec was set up, I guess
At 22kbps it sounded really distorted and some of the sounds literally just disappeared… but it sounded somewhat crisp, the frequency cut-off was about 15.5khz

As far as JPG/PNG, it’s true that a 100% quality-setting JPG will be nearly identical to a PNG at normal viewing distances (not zoomed in), PNG still has advantages. Every time a JPG is worked on and saved it’s recompressed, slowly degrading it more and more each time. It also introduces compression artifacts which you may not even see. If I’m working with an image with lots of white space, and I’m doing flood-fills for some of those areas, and it’s saved as a PNG, it will remain pretty much perfect no matter how many times I open and resave it. Just like a BMP file. But a JPG may introduce compression artifacts which aren’t as obvious until you try to flood-fill, and you end up with a bunch of specks.

mp4 is better
Have you compared the two?
Try a 96 mp3 and then try a 96 mp4.. there’s a huge difference
160 to me sounds decent… I can still tell the difference, but it’s not NEARLY as bad as 128
160 mp4 or 192 mp3 is about as low as you can go before it really starts degrading the quality
Opus is better at lower bit rates than vorbis (below 96) down to about 64
You can just do ALAC for apple devices… it takes about 5x longer to compress (still like maybe 10 seconds for a 5 minute song) but is only about 1% higher file size than FLAC… it still reduces the file size by about 30% from wav
Also… jpegs are actually really awesome and sometimes don’t reduce the quality that much at all
PNG is 7.9mb
Maximum compression with TruePNG and advpng 6.4mb
99 quality jpeg 1.5mb
Sure, you can tell a SLIGHT difference when you zoom in…. but it cut the file size by over a quarter, even after maximum lossless compression
I remember this. Do you remember when CompuServe announced that people using the gif format would have to pay a licensing fee, despite originally releasing it as an open and free format?
I think it’s funny with the resurgence of gif animations people today thinking the format is new, when in reality it’s ancient.
The patent for it expired in 2003. I wonder if that’s the reason you suddenly saw them explode everywhere again.

GIF encodes images by lossless compression. It was made for simpler graphics without subtle color variations. In other words, it does better with the actual show characters (large fields of one color) than screencaps (NTSC-induced variances in color within what were originally fields of one color) or detailed artwork (actual variances in color). To over-simplify, the majority of its compression is turning long lines of one color into, basically, the length of that line. In other words, instead of specifying the RGB value of purple 1000 times (or even saying that it’s purple 1000 times) for a 1000-pixel-long section of Twilight’s body, you’d define purple once for the whole image, then when you get to that spot you’d say only (purple, 1000). So say a line of Twilight’s body on a white background would be something like (white, 500)(dark purple, 10)(purple, 1000)(dark purple, 10)(white, 500). GIF is still the best format for that kind of graphics. For this, not so much.
Unfortunately, PNG may not be better, because while it compresses subtle color changes better, it also allows more of them, and greater depth of colors. You’d need to force your graphics to 8 bit color and select only 256 colors (no mixing) as your entire palette before you even start painting, to probably achieve better compression than GIF. If you painted and then encoded, you’d be looking at make the animated GIF, decompose it to individual frames, re-save each frame as PNG, then put them back together as an animated PNG. And you’d lose quality significantly compared to the original animated GIF due to encoding mismatches. Really what you want is the raw file for whatever program you used to make this animation, but Derpibooru and a browser can’t possibly display that. Nobody without that program (whatever it is) could. Maybe a still here and a link to the full image looped for a few minutes on YouTube, or to the raw file on some other file storage site? I don’t know of a perfect solution.
P.S., I hope the jellyfish doesn’t sting her.
Completely different formats for different things. MP4 is not a successor to MP3. MP3 stands for MPEG-1 Layer 3, which is meant for audio. MP4 is MPEG-4 Part 14, which is a container format for video and audio.
I still prefer using MP3, but other formats like OGG Vorbis and FLAC are becoming nearly universally-supported now (excluding Apple devices) and offer better quality-to-bitrate. Especially FLAC, which is lossless and audibly transparent to the original source (in fact, you can even use FLAC files to recreate the original CD 1:1.) But the trade-off is the filesize is much, much larger than MP3 or OGG.
I can’t stand 128Kbps MP3s either. When the format took off, dial-up was still the primary internet access people had, and large file sizes (10MB was fairly large on dial-up) sucked, combined with more limited storage space at the time, 128Kbps was settled on as the “standard” for “CD-quality” (which it wasn’t) and most people couldn’t tell the difference, especially with crappy speakers/headphones. Even today you’ve got people who don’t care if they’re playing a track back in crappy ripped-from-YouTube quality.
I rip all my MP3s in 320Kbps, which is the max the format officially supports. That’s the quality level I prefer. And I’m one of those people who can tell the difference in higher bitrates, and have the hardware to take advantage of it. 128Kbps-160Kbps is really noticeable. 160Kbps-192Kbps slightly less so, but still noticeable. 256Kbps-320Kbps is where it starts to get a little murky. It also depends on the track due to the way MP3 compresses things.
