the best as in most backwards-compatible choice is PNG 1) grab a frame to use as a preview, save as PNG 2) add all I-frames and save as an APNG, rename to PNG 3) add P-frames, B-frames and uncompressed WAV-pieces between chunks containing the I-frames and there you have it, a file that's an animated PNG in firefox, a normal PNG in other browsers and a video

MrMoo posted:Beyond that not forgetting there is fractal compression which is very compute intensive, produces better compression rates and has a nice blurry artifact when scaling. There was Fractal Image Format (FIF) back in the late 90's, and I believe some US government agencies used it for ISDN based video conferencing at very low bit rates. I remember getting so very excited when I heard about this. Bitmaps! Fractals! Resolution independent! Zoom without pixelation! it hit all the right points to capture my imagination. then it came out but was wrapped up in so many patents that it was impossible to find a version so you could try it yourself

pagancow posted:Some guys are working on a vector based video codec instead of a pixel based one I've had the paper about this on my reading list for a while, read it just now. It's unfortunate and a bit ironic that all the demonstration images have horrible jpeg compression, but this side result illustrates the technique well, I think:  though i'm not sure about using contours as the building block, especially for a video codec. with video wouldn't it make more sense to consider a single frame as a 2D sampling in a grid pattern of a point-cloud in 3D and then try to reconstruct the point-cloud with time and depth from motion, like Kinect? the reconstructed point-cloud could then be approximated using an animated 3D mesh, which would be almost trivial to decode with hardware-acceleration using a highly detailed 3D mesh as a storage for your raw video would have other advantages too. like in film you could adjust a camera's position within some limits e.g. during editing. or you could use another camera to capture anything that was occluded in the first camera, combine two or more of these together and do impossible matrix-style moving cameras without special effects

I proposed using 3d geometry for compressing images earlier, turns out homeworld 2 did just that for their background images:   how it's done:    also I guess it only gains up to a certain amount of high-contrast detali, which is part of why those images are more about style than accuracy more details here, also there's an animation showing what the background objects look like from outside the box

ahmeni posted:This just looks like its a regular image projected onto a sphere? Where's the storage part? the sphere, which is laid flat in the wireframe gifs, contains RGB color data from the original bitmap only at each of its vertices. the colors for each filled triangle come from a linear gradient which is calculated from the 3 vertex colors you can see in the wireframe how the size of the triangles changes where smaller details from the original need to be kept

Doc Block posted:So it's a plain old 3D model...? Storing the color information at each vertex instead of texture coordinates isn't exactly a big deal. yeah I guess, though usually vertex colors are used for adding color variations or shadows and ambient occlusion to existing models rather than the opposite like here, the model adding details to the coloring here's what a "compression artifact" looks like:
