What is AVC (video) CODEC? - Blu-ray Forum

Marcusarilius · 09-13-2007, 01:14 AM

Can someone explain to me what the AVC (video) CODEC is for film transfers and how is it better than others? Thank you, Mark

MPEG4, H.264, a.k.a. the standard. Guess which one was rejected . . .

I prefer it because M$ isn't associated with it.

Thank you but still Greek. Pretend like I'm 5 years old.

Here's a link to Apple's faq. It's their latest compression technology. Probably a good start. I didn't see much in terms of comparison to competitor's stuff.

Being a non-greek 5 year old isn't what its cracked up to be. Maybe when my brain develops more I'll understand this better but am glad its was used for Underworld BD.

Simple answer, it compresses video down without that much reduction in the video quality. It just eats up system resources to do so [which is why you'll see with PC playback at 1080p, alot of folks are going to want assists at first, much like with Mpeg2 and DVD]. VC-1 is a bit less system intensive, but, well, it pays the price for that in video quality [some would argue the parts of the video that are lost are better lost mind you, but that's subjective].

Contrary to popular belief, Apple didn't create AVC(H.264). They just chose to license it for their products.

It is just the natural progression of video codecs. It is technically mpeg-4 part 10 and has many uses and various degress of quality just like mpeg2.

No system issues with regular home theater set-up though. All will run smoothly? Does anyone know what current BDs are AVC CODEC?

Filter by codec. There are currently 83 AVC BD's.

Thank you. Great info on each disk. No wonder The Descent looked so good in those dark carverns.

This gives probably more information than you ever cared to know though...

I'm pretty sure Sony and Disney are the only companies that use the mpeg4-avc codec. As a result, all of their movies look superior to the other studios IMO.

FOX AND LIONSGATE are using it

PARAMOUNT USE IT BEFORE

Except for WARNER Which still on doing the same exact lower VC-1 Starved codec done for HD-DUD

Before they quit publishing on Blu-ray, Paramount was using AVC as well, and their AVC encodes were really good, too.

Fox is now mostly AVC, as nearly all of their upcoming releases are going to be AVC encoded (except for Edward Scissorhands ...

).

I like both AVC and VC1. They both look amazing when they aren't bit-starved.

Here's a comparo in wiki, but im not too tech savy so i can't say how correct it is. Maybe someone can confirm some of it or whatever.
