Archival of Dark_Shikari's blog?

Anyone have a link to an archived copy of our old friend Dark_Shikari's blog "Diary of an x264 developer"? It was super insightful and I'd like to refer back to some older posts but the site is down and I can't find it on the wayback machine.

This was _SUCH_ a good post on encoder latency.

Lots of great posts in there. Probably some of the best educational material on real-world encoder design and implementation out there.

Another great one, this time about VP8

6. Not supporting interlacing.

THANK YOU THANK YOU THANK YOU THANK YOU THANK YOU THANK YOU THANK YOU.

Interlacing was the scourge of H.264. It weaseled its way into every nook and cranny of the spec, making every decoder a thousand lines longer. H.264 even included a highly complicated — and effective — dedicated interlaced coding scheme, MBAFF. The mere existence of MBAFF, despite its usefulness for broadcasters and others still stuck in the analog age with their 1080i, 576i , and 480i content, was a blight upon the video format.

VP8 has once and for all avoided it.

And if anyone suggests adding interlaced support to the experimental VP8 branch, find a straightjacket and padded cell for them before they cause any real damage.


Here we are today with kludgy interlacing support in HEVC

Sorry I don't remember which one of you encoding gurus posted this:
Foolproof VFR to CFR conversion
Quote:
If no frame rate is available, or even if one is but it's nonstandard, I'd just open with DSS's convertfps=true with exactly double whatever the final framerate of the DVD is, weave the fields, and encode interlaced. That handles all VFR as optimally as possible without either blending or mo-comp.

More advanced analysis could reveal where progressive with soft pulldown is possible, but you have to parse the timecodes for that and pass the ranges on. Encoding interlaced just works.
So is it Encoding interlaced just works, or should should it be avoided by all means?

//EDIT//
It was foxyshadis who posted this...

Indeed! Most of the stuff that Dark was talking about 11 years ago are still very relevant today and offer a very important insight on how things work and why they were implemented the way they have been.

Victory!

The thing that kills me is that we almost got interlaced kicked out of ATSC 1.0 and could have been rid of it a couple of decades earlier. Intel had convinced everyone that doing SW deinterlacing was too hard for PC clients. The broadcasters were about to give up when Intel said "no, we figured it out." If they'd just shut up for another month...

I think she works now out of the spotlights at a computer company with a fixed monthly income which is obviously welcome for anybody.
We don't either hear a lot about pengvado or other video compression legends.

That was a reference to the "other video compression legends" part. Skal contributed to XviD.

Oops, yeah, I'm thinking of pengvado from the post one up from yours.
