In honor of me winning "All Around Nerdiest" of the forum by default (Jonny_B conceded), I thought it would be fun to have an ask me anything thread. You ask the questions, I answer them to the best of my ability and as truthfully as possible. You can answer questions posted as well or comment on answers, but I'm going to focus on only answering questions. So try to stump me or let me help you with life's mysteries.

You hate divx compressed shit in an .avi. What should I use instead that will play on a majority of PCs?

Wetness is the sensation we associate with viscosity. Water is a very viscous substance, thus, feels "wet" to us.
It plays on a "majority" of PCs only after patches are applied. It plays on exactly zero clean installs of Windows XP, Vista, Mac OSX, or any of the major Linux distros. Granted, its quite simple to install and some players will even fetch the codec in the background for you, but its not a ubiquitous codec. As a matter of fact, DIXV is a closed source / closed standard spin off MPEG4 ASP. Why would you want to use a proprietary version of an outdated codec? There are better compression schemes on the market now, open standards ensure better compatibility, and MPEG4 ASP doesn't natively support HD. In fact, the only big breakthrough of ASP is B-frames, otherwise, it has the same compression/quality ratio of MPEG2. GMC takes too much computing power for its compression gains and doing this level of compression without a native deblock filter is fucking retarded. Trying to force HD in ASP is wasteful (bit wise) as it wasn't designed for it and you won't see the same compression ratios as other codecs. The entire broadcast industry blew by ASP in favor of AVC (H.264) and VC-1. Do you think tens of thousands of video/broadcast professionals somehow missed something a couple of internet pirates favor or is it possible the pirates just don't know what the hell they're doing?
As for not using AVI, let's start with what it doesn't naively support without hacks :
- B-frames
- Chapter markers
- Subtitles
- Menus
- Meta data streams
- Variable Audio Rates
- Variable Frame Rates
- Pixel AR or irregular pixels
- Adaptive/Hierarchical GOP schemes
- Certain multichannel audio schemes
- Packaging appropriate for streaming content

Soooo do I look as young as I look?
Are you my real uncle and if so why do you touch mommy like that????
BTW Fly report post is very helpful I don't have to leave the thread to see if this is on topic or not.

Why the hell not.
I have no idea. It started thinning out in a weird pattern. If I grew it out now, I'd have a ponytail in the front like a unicorn and the monk's ring around my head. Rather than suffer that, I just shave the mofo.
Its all about our emergence from feudal society and the rise of the middle class in the Age of Enlightenment. There was always a strong barrier between the haves and the have nots; the elite and the peasants. Through reason and thought, common people started to pull themselves up into socio-economic strata formerly reserved for only nobles and high level clergy. The tension of which you speak was the angst of being held down so long combined with the excitement that there was finally a path to follow to elevate themselves out of it.
How about we just ask questions you really care about the answers to?
Great. So anyway, what offers standardization, good compression, and zero to minimal codec installation?
(btw, I meant xvid, not divx)
Because I haven't seen that movie since I was in grade school and I'm really trying to answer questions off the top of my head and not just google for answers.
Use H.264 in either a MP4 or MKV container. Its an open standard and you can get better compression ratios out of it. I'm getting D1 resolution and quality at 1.5Mbps. The industry is looking at 8Mbps for HD (as opposed to 19.39 Mbps for MPEG2), but I've seen good pictures as low as 3Mbps. Almost any Blu-ray rip should already be encoded H.264, so this will save you a lot of time in that you'll only have to repack the container. Since its being picked up by broadcasters as the next standard, you should see lots of devices with dedicated H.264 decoders coming to market soon and they'll also quickly drop in price. If you want to be on the bleeding edge of standards, I can show you how to use a wavelet encoder, but Dirac/Schrodinger is still very much in the alpha stages, so future compatibility is iffy. H.264 is going to be the codec for the next 10 years.
my experience with h264 says that it requires a good amount of CPU. Say I wanted to compress a 2 hour movie into 700MB, would it require more horsepower than an xvid?
i'm going to buy a new snowboarding helmet and boots, what should i get?
