Uncompressed media (such as on Laserdiscs, Audio CDs, and WAV files) or losslessly compressed media (such as FLAC or PNG) do not suffer from compression artifacts. These compression artifacts appear when heavy compression is applied, and occur often in common digital media, such as DVDs, common computer file formats such as JPEG, MP3 and MPEG files, and some alternatives to the compact disc, such as Sony's MiniDisc format. The most common digital compression artifacts are DCT blocks, caused by the discrete cosine transform (DCT) compression algorithm used in many digital media standards, such as JPEG, MP3, and MPEG video file formats. The compression algorithm may not be intelligent enough to discriminate between distortions of little subjective importance and those objectionable to the user. If the compressor cannot store enough data in the compressed version, the result is a loss of quality, or introduction of artifacts. Lossy data compression involves discarding some of the media's data so that it becomes small enough to be stored within the desired disk space or transmitted ( streamed) within the available bandwidth (known as the data rate or bit rate). also take a look at the ffmpeg documentation.Loss of edge clarity and tone "fuzziness" in heavy JPEG compressionĪ compression artifact (or artefact) is a noticeable distortion of media (including images, audio, and video) caused by the application of lossy compression. I just got silver for this, so i guess someone is still reading it a more direct answer for "how do i turn a video into a gif?" is follow giphys guide on making gifs. granted, this is also a webm that is also compressed, so the quality demonstrated here is less than what you could get. Here is a demonstration of scaling and transcoding to both webm and gif side by side with the original mp4. the above command could look something like ffmpeg -i input.avi -an -vf scale=: -c:v libvpx -b:v 1200k output.webm. they offer all the benefits of modern video and audio compression without the limitations or size of the gif format. VLC Player, all platforms, for those stubborn video filesĪnymore useful info? familiarize yourself with file formats and file typesĪvi is a cunt to work with which is one of the many reasons why avidemux moshing is so annoying, but once you have your moshed avi you should be able to do something similar to ffmpeg -i input.avi -vf scale=: output.gif.įor the sake of quality, you really ought to use webm instead of gif. Xee for mac, for those stubborn image files IrfanView Graphic Viewer for windows, for those stubborn image files
Datamosh gif software#
What if I break my file and my usual software can't open it? try the alternate software below Tutorials, common tools, and some community links, compiled by /u/wayspurrchen.ĭatabending and glitch art primer, part 1: the wordpad effectĭatabending and glitch art primer, part 2: sonification.Of course this is subjective and rarely happens, but if your post is removed and you feel it shouldn't have been, message us!
Datamosh gif mods#
The mods reserve the right to remove low effort posts Any more than 3 should just be put into an album and submitted as one post.ĥ. We like seeing the comparison, so post the original in the comments or with the glitch in an album.ĭon't spam the frontpage. But if you aren’t doing something particularly new, please post it in either /r/deepdream or /r/pixelsorting
If you’ve implemented a pixel sort as part of something else, or it is particularly unique, please post it here. r/Glitch_Art is officially designated as the Demilitarized zone between these two feuding states. Cool it on the Deep Dream and Pixel Sorting images If you post someone else’s work, you must credit them, or if you don’t know who made the work, state that it is not yours and hopefully someone will chime in. Like, a nipple is okay, but for more than that go to /r/NSFWGlitchArt or /r/glitch_porn If you have criticism keep it constructive and follow reddiquette. If you’re keeping your secrets safe, then post elsewhere. If someone asks how you made a glitch, give a good detailed answer.
Glitch is very much a DIY artistic movement, as such sharing techniques and methods is essential to keeping it alive and interesting. Mods will enforce these in all cases Rules Though you can post others work, it's strongly encouraged that you post your own creations. Post links to glitch art and anything related your creations, others creations, tutorials, tools, whatever.
