This article was originally meant as a way to identify useful square pixel resolutions for digital NSTC 16:9 content for the web, because 480p would be 853.333… px wide in 16:9, and neither 853 nor 854 would work in that encoder, and I didn’t want to settle for 360p.Start of 2012 Hungarian F1 GP … Resolution: 1920x1080 Sebastian Vettel, Red Bull RB7 … Resolution: 1920x1080 HD Wallpapers 2012 Formula 1 Grand Prix of Korea | Formula 1 Resolution: 1920x1080 Formula 1 Wallpapers | HD Wallpapers Resolution: 1920x1080 HD Wallpaper 2010 Monaco F1 GP_05.jpg … Resolution: 1920x1080 Standard … Resolution: 1920x1080 Formula 1 Driver Kimmi Raikkonen picture Resolution: 1920x1080 Pics Photos Ferrari F Hd Wallpaper Hd Wallpapers Nano Trunk  Nowadays, you should probably just use standard 720p and up. So, 16×16 being the largest multiple-of-2 macroblock that can divide digital NTSC and PAL resolutions cleanly may have been a factor in the design of H.261 which used macroblocks to address compression limitations in the non-DCT-based H.120 (H.261 luma samples were 16×16): 601 sampling rate, you would end up with 704 pixels wide, which was bumped up to 720 pixels to account for inconsistent widths of analog NTSC and PAL motion pictures: Then, to fit a 4:3 480 line picture according to the Rec. “This blanking interval was originally designed to simply blank the electron beam of the receiver’s CRT to allow for the simple analog circuits and slow vertical retrace of early TV receivers.”:Įffectively, NTSC had 525 lines of content per frame, with 483 visible and later 480 visible, and PAL had 625 lines per frame with 576 visible: For example, HEVC replaced macroblocks with coding tree units (CTUs) that can support samples up to 64×64 to more efficiently code large images in 4K video.ħ20×480 and 720×576 don’t come from there, but 16×16 probably does.Ĥ80 and 576 come from the luma sampling rate adopted by the industry when converting analog video into digital, which itself comes from the nature of analog NSTC and PAL signals which included a vertical blanking interval so you wouldn’t see the retrace on old TV sets. These are indeed divisible by 16, and 16×16 is the maximum macroblock size for most MPEG family codecs, so this would indeed maximize compression efficiency because larger macroblocks allow for better compression of larger images. In terms of not adhering to 16:9 resolutions, it’s possible you’re thinking of the D-1 SMPTE digital recording video standard, which used non-square pixels to represent NSTC (720×480) and PAL (720×576), both resolutions adopted by the DVD standard, staying the same whether the image was 4:3 or 16:9. Well, the only reason I added the 8×8 highlights is because back when I made this list, the ffmpeg-based GUI encoder I was using would only work with resolutions that were multiples of 8, perhaps an artifact of H.261 having fixed size 8×8 transform blocks, or an attempt at following common resolutions: That’s because DVDs were originally made to comply with the NTSC broadcasting resolution, which is a non-square pixel standard using the resolution of 720 by 480 pixels, stretched to accommodate either 4:3 or 16:9 content, never producing a true 16:9 resolution.ĨK UHD / UHDTV2 / Super Hi-Vision / BT.2020Īuthor Pacoup Posted on JApCategories Video Tags featured Note: If you’ve ever worked with SD content, you’ll notice that no resolution here fits the DVD standard. The table goes up to 1080p and includes common resolutions like that of a typical 27 inch 16:9 computer monitor and Super Hi-Vision. In an effort to enhance the knowledge of the video-making community, I have compiled a list of all true 16:9 video resolutions, including their associated standard when applicable, as well as when the resolution is divisible by 8, which is useful for limited video encoders. Updated to include full range of resolutions up to 8K UHDTV.
