Steve Jobs talking about H.264

[DisDwarf]

Good speaker. However, perhaps we should focus more on learning how to shoot high-quality videos in the first place, rather than arguing about compression technologies ;-) || kalos omilitis, ma isws tha tan kalitera na mathename na travame kalo video prwta anti na milame gia simpiesi...

i thought he would have a deeper voice!! hahaa! ohh WOW! ... but ... yeh he is pretty amazing!

[baghdig2520]

@Ehal256 they're saying that if you have a master copy (say from an editing program), encoding it to h.264 looks better than encoding it in some other format...there's no "adding of quality anywhere"...

[ndb916]

Ehal256 you obviously have no idea how H.264 works.

[vkyle52]

@ndb916 How does it work, smartguy?

[McGravier]

so quicktime have: live resizing, full hd playback, mpeg4,h.264. full screen overlay controls... Well im sure there is more, it can play divx/xvid without any additional plugins, it suerly can play subtitles without additional plugins, it also can play rmvb like VLC media player, and it is so awesome because it does not load any shit into autostart and OMG ONE BUTTON AUDIO & VIDEO RECORDING!!!!1111 ->for dumb idiots - thet was sarcasm

[gunpder94]

BEST Quality!! indeed

[Cyberman86]

whats the name of the Demo Movie they are playing it seems a good movie.

[YungQb7]

I would have to go with: House of Flying Daggers. I have it, but i haven't gotten around to watchin it lol

[genomastergenomaster]

actually it is a good movie, but the end is lol

[VideoUploaderr]

Totally agree with you! you can't increase the quality very much, but if you look very closely, you will see the quality is still much better than mpeg-2 when you convert it trust me..

[Ehal256]

that's doesn't even make sense. If something looks bad, you can't improve by compressing it further. H.264 is designed to keep as much quality as possible while compressing it. It's not lossless, which means every time you compress it with that codec, it loses quality. No matter what codec you use, it's impossible to actually improve the quality of a video, by just encoding it.

[VVWEtitantrons]

@Ehal256 Yes it is, dumbass, encode a VP6 FLV file in WMV9, and you get a huge quality boost, plesae know what you're talking about before saying stuff about things you dont know

[Ehal256]

@VVWEtitantrons Where does the quality come from? Video codecs are, with few exceptions (HuffYUV for example), lossy. This means that each time video data is encoded, some data is sacrificed, to enable further compression. Au contraire, a lossless codec tries to compress as much as possible without sacrificing data. This means that, when encoding video data, there will ALWAYS be a loss in quality, however neglible (unless, again, you are using a lossless codec).

[VVWEtitantrons]

@Ehal256 WMV9 decodes the VP6 which is imbedded  in some FLV files.

[Ehal256]

@VVWEtitantrons All I'm trying to say is that transcoding data never improves the source quality.

[VVWEtitantrons]

@Ehal256 And im saying the opposite, i agree with you, but in a rare instance trans-coding an FLV file to WMV9 will improve it

[Ehal256]

@VVWEtitantrons Perhaps to your eyes, but not because the quality is actually better. Encoding removes data, it does not add data (and if it did, it still couldn't make up random data that makes the video look better). Get a clue.

[VVWEtitantrons]

@Ehal256 Read up on VP6...

[Ehal256]

@VVWEtitantrons Have you ever heard the term 'garbage in, garbage out'?. Read up on video encoding in general. There is no magic algorithm to restore quality that was never there in the first place.

[Ehal256]

@VVWEtitantrons And you can bring up filters like scaling, sharpening, and de-interlacing all you like, but any "quality" given by these effects is completely subjective. It is you who knows little to nothing about this topic.

[VideoUploaderr]

Yeah Quicktime player can maybe suck, But the codec h.264 avc is the best!!

[VideoUploaderr]

The H.264 is the best!!!! whenever you convert an mpeg2 dvd movie to h.264 you will see the quality!!! 98% more smooth&sharp!!!

[OmegaXalpha]

H.264 does rule, but takes a little longer to convert a dvd tho it than Xvid and I have a really good computer

[YungQb7]

yea thats tru. i would prefer h.264 since it looks betta (on computers that can support it) but with the computer i got, ima use Xvid for now

[catzilla82]

nice....hey resuorce of research papers at "media_h264" google search

[lotus3232]

OH YES !!!

H.264 is a FANTASTIC COMPRESSION CODEC !!!

The XACTI CG+CA65 (that I have)

and the BRAND NEW <<< Xacti DMX HD 1000 >>> HAVE GOT IT !

[FantasyJam]

Nice presentation. the only problem I have with H.264 is it needs a massive amount of memory to stay in sync.

[DoubleGauss]

Steve's a good speaker.

[esters45]

you can be a good speaker too if you buy my booke ^.^ just kidding.

[tnt00z]

extremely quality

[prankstare]

Brilliant presentation

[GenCollado]

^^ Like all of Steve Jobs.
