![]() ![]() ![]() No computer can play long-GOP H.264/5 as easily as they can an intraframe codec like ProRes, DNx, or Cineform. Some computers have the specialized chips, and can do 'hardware' encoding/decoding, and they can handle this without "as much" trouble. So to simply show a frame, the computer has to decode and decompress likely two iframes, store them to RAM/cache, then compute every frame in between from those datasets before they can show the first frame after an iframe. datasets of a) pixels that have changed since the last iframe or b) pixels that will change before the next iframe and c) BOTH. For the other 29 or so frames, they make the computer recreate image data from keeping a copy of that iframe, maybe decoding/decompressing another iframe, and then using charts of pixel data.Īs in. They don't actually record all of every frame, they only record an actual frame (called iframes) every 9-30 or more 'frames' of video. They are the worst media to edit from in any NLE. H.264/5 are great at storing data in a very small space. ![]()
