One under-appreciated advantage of H.264: it's the last video codec where the artifacts look obviously artificial. Modern codecs have artifacts that look too much like real objects, so they take more brain power to ignore. After watching low bitrate H.264 for a few minutes I stop noticing the artifacts, which isn't the case with modern codecs.
- reacweb 7y agoVery interesting. Do you have links on this subject (or could you write an article) ?
- mrob 7y agoIt's just personal observation. I noticed the same thing in audio artifacts with the RNNoise demo from xiph.org: https://people.xiph.org/~jm/demo/rnnoise/ https://people.xiph.org/~jm/demo/rnnoise/
- jeffhuys 7y agoWhat codecs are you talking about? I'm interested to see these artifacts for myself.
- mrob 7y agoComparison videos from: http://video.1ko.ch/codec-comparison/ http://video.1ko.ch/codec-comparison/ http://video.1ko.ch/codec-comparison/videos/vp9_562.webm http://video.1ko.ch/codec-comparison/videos/vp9_562.webm http://video.1ko.ch/codec-comparison/videos/x264_562.mp4 http://video.1ko.ch/codec-comparison/videos/x264_562.mp4 At 15 seconds, in the VP9 version, it looks like smoke is pouring off the top-left metal pipe of the machine. It immediately draws my attention because it's so out of place. But in the H.264 version, the whole image is noisy, so nothing distracts me.
- PuffinBlue 7y agoI'm not really sure which is which but the webm version looks way way way better to my eye. Not even any comparison really.
