Arguement over size of HD/Blu-Ray Content

[Skrumzy]

Long time reader and researcher, finally made an account for later use when I dive deep into digitizing my TV viewing shows..

I got into an arguement today over the size of a blu-ray movie..So I tried to get a straight answer from google but that didn't turn up, so can anyone tell me the average size for a Blu-ray Movie that is encoded into 1080p? Appreciate it in advance.

What's the average size of a DVD ?

Depends on the bitrate and the choices the studio made when authoring. Somewhere between less than 25GB and more than 25 GB.

Thats what I was trying to tell him..He thinks that downloading a torrent that says its HD and only 2 gigs means that its blu-ray quality..I tried to tell him that that he was probably watching 720p and that it depended on the bitrate and audio..But by standards a blu-ray movie would be around 25GBs for an average movie and over 25 for the 3 hour movies correct?

2GB is small, even for a 720p BluRay down convert, so yes, you are right and he is a dick.

But then people also believe that an Xvid that has been encoded down to less than 620 pixels wide and 350 MB in size is HDF because it says so in the file name.

Like the BluRay example, all it means is that the source was HD. What is left to be downloaded is far from the quality of the source.

Absurd. :P If it turns out he's ineducable, don't bother arguing the point any further, you know what they say about arguing with a fool.

You're correct that a goodly proportion of movies on BD will actually fit on a BD25, movie only. That certainly is Blu-Ray quality.

There's more room for disagreement when discussing what is *acceptable* compression. H.264 is very efficient. In my own experience, no one I know, other than myself, can tell the difference between a re-encode of 1080p on a BD9 (BD structure on a dual-layer DVD), and the original. Stipulating a ~ 2 hour movie viewed on my 47" LCD. Is it Blu-Ray quality? IMO, no, not strictly speaking.

But anyway, what your acquaintance said is just amazingly ignorant.
