1080P on DVD5 is very doable

[fatso485]

Hello all

A friend of mine just showed me a copy of “over the hedge” @ 1920 * 1080 that I’m not sure where he got it from. The quality of the video is just beyond amazing. I saw it on an Acer 37” 1080P LCD TV (using xbox360 streaming the file from the desktop)

What’s even more amazing however is the size of the file. it was only 3.99 GB. The video was WM9 and the audio is 384kbps 6chanels.


If I assume that h264/x264 is about only %20 more efficient than VC1. Can someone explain to me why the heck many people here are complaining about the noticeable quality loss that they expect to see when they encode the HDDVD movie to a 8.5GB

i recently coded million dollar baby from a german HD-source to a 4 gig XVID!

settings for xvid was h263, CQ3, VHQ1, no QPel... ~14 fps @ 1920x800

Million Dollar Baby is real easy to encode... cinemascope, lots of talking heads, mostly stationary cameras, distant (i.e. out-of-focus) backdrops, low grain/noise.

Still, 1080p DVD5 is quite doable in most cases. If you sit at about 24 inches from a 24 inch monitor like I do, a DVD9 h264 encode will look crisper than DVD5. For "normal domestic use" (say eight feet from a 42 inch screen) there's unlikely to be a visible difference except that perhaps blocking might creep in.

i still got tears of the sun and finding nemo, let's see how difficult these are ;)

Hi!

The filesize and quality you've described may not really be that exceptional, when you consider that you're talking about an 83 minute (including credits) CGI animation.

You might want to view a similarly created HD of a high action full length movie - and evaluate it for both quality and filesize...

i was watching it from about 4 feet away and i could not notice any artifacts. any random frame is good enough to be my desktop background.

giving the X264 is better than VC1 it should be no problem to cope with movies that are harder than over the hedge don't you agree.

i think people will start shooting for 4500MB (about .1 bits/pixels)for HD just like we used to shoot for 700MB (with about 0.2 bits/ pixel)for SD movies. DVD9 blancs cost 10 times higher than DVD5 over here so i see no reason to bother with it considering what you can get with a properly encoded movie

@tos-mavric
dont you mean 24fps. and how was the quality of your XVID

@fatso485
no for this 2 hour movie encoding took about 3h30. don't forget that my source is h264 1080p ;)
quality is great, my pc-monitor has only 1280x1024, so i can just watch the movie downsized to 720p. no grain or smoothing issues for this movie, since it's already quite "clean".

i'll definately continue coding my hd-movies with xvid, as it's much easier to decode. if a movie isn't as compressable as million dollar baby, well, then i'll resize to 720p

You wont see any artifacts on a 37" screen. Blow it up to 120" on a projector and you will. 37" is about as tiny as it gets when it comes to HD.

And for the special cases, you can always split it across a pair of DVD5s.

I'm not surprised, although for the best possible quality it'd probably be nicer to stick to DVD9. With the advent of MiniHD (HD DVD on DVD9) we'll even be able to have 2 hours of 1080p video playable in a set top player.

I must admit the tests I have done with 90 minute movies in VC-1 with Sonic Cinevision suggest that DVD-9 will not be enough space. Far too much grain is lost IMO.

My thoughts would be:

- Cinevision isn't very good, compared to PEP?
- Non HD DVD Spec video can make more efficient use of Long Gop encoding.

Just my 2p worth

Did you try using the grain related features in cinevision? It makes things slow, but if you want to keep the grain it is there. Although maybe thats only avc.
