Lurker with a quick question
Hey. I've used this site on and off for a couple of years, mostly to fill in my collection with older videos that I cant find via other methods. That collection, however, was started in earnest a few years ago with the intent on being compressed videos. x265 most of the time. Just wondering, why is it that the videos here aren't compressed?

All videos you'll find here are compressed. The used codec varies though. There are several different reasons for that.
In PATM, only official releases are allowed. And even in 2023, most of the recent releases are still AVC / H.264 for compatibility and licensing reasons. Commercial licenses for HEVC / H.265 are a nightmare to obtain. Because of that, it's difficult for companies to produce and distribute HEVC content, and on top of that, they can't even be sure that their intended audience is able to play HEVC videos on their preferred device, because the manufacturer of said device, hard- and/or software, might have the same HEVC licensing issues. This meant that HEVC adoption was very slow from the start and never really took off. In other sections, custom re-encodes of videos might be allowed, but many people don't have the means to re-encode the video. That is knowledge and the computing power to do it in a reasonable amount of time. I know that a few people do it though, they share their HEVC re-encodes. As far as I know, even free HEVC implementations, like x265, didn't solve the problem. Other free competitors, like VP9/AV1, are also available and haven't seen widespread adoption yet, I guess for the same target audience reason as above. The good news is that this problem with licensing HEVC was acknowledged and with the upcoming Versatile Video Coding / VVC / H.266, they want to address this using a RAND (reasonable and non discriminatory) licensing. So, with that coming, we get a new shot at adopting a modern and highly efficient video codec. The Fraunhofer Heinrich Hertz Institute has already released their source code for a VVC encoder and decoder, some hardware decoders also exist and the x266 encoder implementation is scheduled for releases in the second half of 2023. I'm sure the FFmpeg project is also working on something, don't know their state of development though. I guess we can expect some news in the coming year(s). Only time will tell if it works this time. |

until last year, i dodged HEVC/x265 videos like the plague.
i thought i had a pretty good laptop with reasonable specs, but they NEVER played correctly for me! latest laptop upgrade finally seems to have solved it. but i can attest that anyone with a 2-3 yr old PC will have problems with HEVC/x265. |

bonfire?
not getting the metaphor. is that some GoT ref? in any case, i am AGREEING. they are much preferable to x264...in principle. once everyone's hardware catches up. for now, i'd treat them with caution. |

Treat them with caution, why nothing will happen. Pissing on your bonfire is an old saying from the UK, try Google Code:

more often than not they'd hang the PC, trigger BSoD, or cause a crash. trust me, i WANTED them to work! usually i'd choose vids like that b/c even i could see they were much smaller than the x264s. but i'd generally regret it, since only like 1 in 10 would end up playing. i finally gave up and went back to just DLing x264s instead.

the meaning is obvious; i just don't see how it fits the context there. "A penny saved is a penny earned!" back atcha. |
