i learned a few months ago that even when you connect your computer or console with hdmi to your television, there is a very high possibility that the loving tv does some chroma subsampling to the image which is why text on websites looks like poo poo. i noticed it on my tv, but i didnt know wtf apparently tvs that dont do that are rare.

let me tell you about hfr, having just seen the hobbit: mostly things just looked smoother, i.e. better, but for some reason any time there was a closeup of hands on screen doing something, it looked weird and sped up. the whole movie started with such a shot, with bilbo opening a chest an spreading the map.

how will they distribute h.265? (except streaming) blu-ray disks should have enough capacity for most movies, i think. all the blu-ray rips i've made have been around 20-22 gigabytes, and dual layer blu-rays have 50 gb capacity. so 4*pixels*0.5 bitrate = around 40gb for a 4k movie at current 1080p quality. has there been any talk about higher-capacity physical media? hvd seems pretty much doa, but i guess it's a format that exists by some definition

good news, h.265 supports interlaced video by saving the fields as separate frames and having some flag that tells the decoder that they should be shown interlaced.

i made a screen recording for a class, captured it with a lossless codec. i then encoded it in h.246 dragging the quality slider all the way to "0 (high quality)", and the about two-and-a-half minute 720p video was barely over 2 megabytes and the image quality is prtty much flawless. (it was mostly a static image, but still) i guess what i'm trying to say is that my video codec was not a piece of poo poo.

yes, it looked like the right-side picture, which is "pretty much flawless" lol if you think that a web video about clicking some buttons has to have 4:4:4 video

these are from memory, but i think they were shooting for 2-3 times the processing power for encoding, 2 times for decoding. compared to h.264

i just looked at a cable recording i have and it's about 3.5 Mbps, sd resolution, mpeg2 youtube seems to be about same bitrate for 1080p, h.264 of course this varies by cable operator and such

a 1080p cable recording from the same operator is about 7.5 Mbps, h264. so by this very thorough investigation, i'd say that streaming < cable

does any mp4-like container have support for chapters? mp4? m4v? m2ts? is that information even embedded in the file itself or does some meta file on a blu-ray contain that data. because if it's a separate file then chapter support is a plus for mkv.

nah, on linux the first time you double click on an mp4 it makes you pinky-swear that you have a license to play back mp4 and then when you click yes, it will automatically do a thing and then play the video.

that's not a big deal, gifs have independent frame delays already. speaking of video codecs that suck: webp, the image format that is based on webm, has animation support. at least there are tools that let you construct webp animations, but i don't know if any viewers support animated webp. apparently animated webp frame delays are expressed in ms instead of 1/100 of seconds, so you will be able to get closer to traditional frame rates than with gif.

well, maybe vp9 won't be a piece of poo poo and also actually won't infringe on patents. i like the the idea of a good royalty free codec, but i'm also content if the current situation with h.264 gets repeated with hevc. everything using hevc codecs, but only commercial operations actually paying for it. i guess anyone encoding h.264 right now should pay some licensing fee, but i think mpeg-la has been p. chill about it and not even trying to go after people making pony videos and lets plays, not to mention pirates.

hey, how is 3d image saved on blu-ray? i imagine the normal image data is either left or the right eye and then there is some extra track that maybe encodes the differences between the main picture and the other eye? is there any software that can display (and change back and forth between) the other eye image for any given frame of a movie?

can we talk about webp? because it seems webp is pretty ownage. it supports lossless and lossy compression, with alpha, and animation. and it seems to do each better than jpeg, png and gif. and google might be able to use their high browser market share to actually give the format some chance of making it.
