Conversion quality

Hi Folks,

I was very interested in the detailed answer - how to from Chickenman wrt the correct way to burn dvds.

Perhaps my question has been answered in similar fashion, however I am looking for any information wrt the quality after conversion and perhaps a different set of programs, procedures etc.

When I burn an original dvd to one of my external drives, I use Clone dvd on their 9 setting.

I then convert with AVS4 to a wmv file in HD quality.

The converted movie is never as good a quality as when I simply burn a dvd from Clone, or the original - neither picture nor audio, even though the file size has been increased by about 25 - 30 %.

Any thoughts would be apopreciated, thanks…

If you convert media to another media format you will almost always lose quality. There will never be any quality improvements. Especially when you convert from a certain media format to a lossy media format. Lossless media formats usually retain quality if all parameters are 100% equal to the original source.

Nope! won’t happen!..Can’t create “HD quality” from Standard DVD source…
That said, quality is in the EYES of the beholder…:wink:

That’s correct!..you’ll never have the same quality as the original when converting to another format…And you now have a needless larger file to boot!.:eek:

Leave it alone!..And you’re welcome!..:cool:

With CloneDVD2 ripping to DVD9 preserve menus & removing nothing (It will also show the following even if you do "movie only or don’t preserve menus).In the log at the end it shows transcoder disabled.That should mean the rip is without change.
As posted above you can’t get HD from SD .

Tx folks,

However, I was led to believe that when I copied an HD original movie to the computer to then play on the Xbox, that there would be NO loss of quality!

Typical sales b/s I presume :o

In your original post you state that you are using CloneDVD. CloneDVD only works on dvd-video, and dvd-video is always standard definition. DVD video is, at most, either 720 x 480 (NTSC) or 720 x 576 (PAL) resolution.

HD starts at 720p, which is 1280 x 720 resolution.

[QUOTE=Spydrr555;2511709]I then convert with AVS4 to a wmv file in HD quality.[/QUOTE]This could be the step where your problems occur.

Some programs will up-convert DVD-Video or MPEG2 files to HD at the correct resolutions - in a similar way to hardware DVD players - but my guess is that some do it better than others.

I got reasonable results once using TMPGEnc MovieStyle, converting a 720 x 576 DVB recording up to 1900 x 1080p. On a 24" monitor, it appeared better than the original, but nowhere near as good as native HD. And a quad-core machine took many hours to do all those interpolations on the MPEG2 data to give the impression of HD. IMO the amount of effort makes it really not worthwhile in software.

If you want to have up-converted MPEG2 media files, then perhaps you are better spending the money on a unit which do this in hardware, in real-time. However, MovieStyle has a month’s free trial, so you could judge for yourself.

Tx:

1.) I had never heard of Movie Style, until I connected with this board !

And of course AFTER I had purchased AVS :sad:

2.) I tried it with my fave Casino Royale, and it works much faster than AVS, as it seems to be close to real time. I find this rather curious since it has more bells and whistles (AVS) which encodes at about 500 % real time.

3.) Now you have opened up another pastime, which is figuring out how to rip my music dvds using Movie Style to another external drive!

The objective has always been to sit in front of the tv and choose whichever (movie or dvd) without going through the actual library of all of them on shelves, to choose and play something, as they are all in different rooms in the house.

Much appreciated everyone, and my thanks.
