Does a backup look good on a high-end TV?

[silverbullet99]

I've been thinking that in the future when Plasma/HD TV prices go down, more people will buy them..but my question is how does a backup (that has been compressed) compare to an original DVD when watched on one of today's top Plasma/HD tv?

Since those TV's have more resolution, i always thought that a backup copy wont look as good due to its compression. ( For example a movie that has been compressed 80-90 % -- using dvdshrink)

Hopefully you can clear up this question for me.

thanks.

Current DVD is 480p. 480p looks ok on an HDTV until you see a true HD source and then you don't want to look at 480p again. Sorta like repeat of VHS to DVD.

More compression will be somewhat apparent at 480p (720x480) but all 480p will look crappy next to 720p (1280x720) or 1080i/1080p (1920x1080).

Get ready to do it all over again in HDTV.

You may not even notice the difference. Compared to HD, DVD is a low res alternative. If you made a quality backup, chances are you will be just as happy with it as you would be with the original. And by then, Blu-Ray or HD-DVD will have become the new standard, and you will be buying your favourites again anyway.

I can't notice a difference. But I typically use IC7 to backup DVDs.

actually I should say that in past tense. When I use to backup DVDs, I used IC7....

But I just bought me a HD big screen for christmas and the backups I have made all look as good as the originals.

Many people seem to whine and complain.

I generally have no problems with backups, as long as they are done correctly. It just depends.

You need a good screen to see much difference. It shows mostly as noise on edges, in motion areas and for extreme compressions >50% an overall image softening. All this becomes much more visible as screen size and screen resolution goes up. But as said before, this degradation is less than the large improvements HDTV provides on a good screen.

Current DVD is 480p.

No. DVD-Video requires 480i/576i, depending on which standard TV format it is trying to emulate. As digital video begins to take over, progressive will be phased in, but it will be a long time before it completely takes over.

Kind of makes one want to go back in time and kick the arse of whomever had the bright idea of interlacing.

Well true current DVD is stored 480i, but film sources on current DVD have all the information necessary to create a true 480p 60frames/sec progressive stream even though the raw DVD stream is 480i 30 frames/sec with 3:2 pulldown added for 24 frames/sec film material.

See this overview for how 480p is created in progressive DVD players.

Scroll down to "Progressive Scan DVD Players".

DTV SDTV is currently available in a 704x480 progressive stream (aka EDTV)

What your eyes see is not what my eyes see.....

Frankly I don't see what all the fuss is about & why we should pay $1000 more just to have a sharper picture.

Do I really need to be able to see the needle marks from steriod using baseball players? no

Most of the time Im looking at the captions anyway & they won't be much sharper & I wont pay $1000 just to see them as such.
