What is AVC (video) CODEC?

[Marcusarilius]

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.
