VP8 (Webm) Vs Flash(H264)
When i read about compares about the 2, all say that H264 is the shit if you know what i mean.
I myself Love H264 with x264, itīs Amazing! But when i watch Youtube and compare Webm with Mp4, the Webm is better by quite a bit, havenīt done a Major test, but did compare a bit on 2 videos, and it was always better in Webm. Can anyone tell me why that is? Is Vp8 better at youtubes settings(bitrate limit)? Or am i just blind? |

Oh, i thought they used the same on letīs say 1080p etc, (the videos were My own videos, so i had the Raw original to compare to).
But i guess they use higher settings for some reason, though the size was the same i guess they use some pretty fast h264 settings to get by? I have wanted to do that, but i canīt get the encoder to work when i made a build. Can you link the latest encoder, or build it for me if you have the possibility? Thanks |

Yes but... - new codecs are good for PC (CPU vendors) and some mobile devices but hey are bad for industry with HW decoder implementations - even if HW is primitive and specialized semi programmable DSP still it can be less efficient and some times can't be reprogrammed at all - they introduce new codecs faster than market can adopt them - this is insane.

Well... given H.262 was adopted for std-def TV broadcasts. H.264 was adopted for high-def TV broadcasts. What's the betting H.265 will be adopted for ultra high-def TV broadcasts

they adopted subset of the h264 standard for high-def stuff. Dunno why. Maybe because otherwise it will be too expensive to produce hardware that can decode it and they will have hard time filling all space on blurays? If that's so, by adopting h265 they'll lose more than win, money-wise. cause it will be more cpu-hungry and they will have to sell 1BD where now they sell 2. Or if they'll adopt subset again, it will be no better
EDIT: however they may adopt subset and force everyone to buy new hardware to get the same stuff (from user's point of view)... that will be no good =) Last edited by Keiyakusha; 8th August 2012 at 20:34. |

Okay but one last thing, will VP8 be able to Beat/Compare to X264 for itīs use across the internet?
Or do you think itīs a failed project? And about X265, i read that itīs supposed to have up to 50% less files for the same quality as X264, is this true or overestimated? Thanks |

regarding vp8
dark shikari says noooo ... regarding future x265 in theory yes ...

Please understand that there is a difference between a video format (H.264 and VP8) and a video encoder (x264 and libvpx). If I remember Dark Shikari's writings about VP8 correctly, VP8 could be a decent enough competitor to H.264. The encoders are a different story. As far as I know, libvpx does not come close to x264 despite some "recent" improvements to libvpx. The xvp8 spin-off is still a work in progress.
As for the upcoming video standard widely known as H.265 or HEVC, it is widely said to be "50% better" than H.264 but there don't seem to be any encoders ready for a comparison.

Yes of course, but i donīt understand the thing with the different Encoders, i mean, from my perspective, H264 is H264 no matter what encoder, but this isnīt true right?
Even if the bitstream and all is following the standard, different Encoders do better or worse, and x264 is The Best(i think?) H264 encoder out there? But that is the lack from libvpx (Googles vp8 encoder?) compared to X264(i understand that x264 has been massively improved by the community over the years.). |

basicly vp8 standard does NOT have as advanced algorithms as h.264 specification.
vp8 is like mp3 where h264 is like aac or opus in audio compression

It has only one advantage (that 99% people doesn't care about) and a lot of disadvantages.
- x264 is much better that any vp8 encoder - ... and even if there was encoder as good as x264 - it still would be worse. - zero hardware support. While any modern device supports h/w AVC decoding. - even Flash doesn't support it, so you will have to use ugly and buggy html5 player. So, who needs it? Only Google. Open Source? Standart? What? Both H.264 and vp8 specifications are open - so anybody can write encoder/decoder. who, and what they were waiting for? Quote:

Oh, i thought that the H264 Standard wasnīt royalty free?
So even if we use X264 to encode to h264, we should still have to pay the royalty fee for commercial use, or something like that? And with the HTML5, i though it was going to be, The Thing of The Year!!, as i mean, itīs not a plugin ad itīs out of the box, like playing from the PC itself. But that doesnīt seem to be the case, as itīs as you say, very buggy and on Opera (my favorite browser) itīs worse of all i think, so i canīt use it even if i want to. |
