I try to use dual layer verbatim for any original dvd that are 6.5GB and bigger. If it's lower than 6.5GB (just the feature film), I shrink it to DVD-5 (4.7GB).
Is the quality noticeable on a computer? How about on a upscale DVD player?
Most people that compress movies in order to fit on a dvd-5 prefer to keep compression above 70-80% in shrink. In my opinion quality loss isn't noticeable until you hit 65%. Just make sure that the quality enhancements in dvd-shrink are turned on and you should be fine.
I don't have the ability to burn or play DL media so most of my back-ups range between 70-90% compression. They pretty much all look the same upscaled on my 50 inch plasma.
By the way try to avoid verbatim made in India, the quality control there is terrible.
I can tell some difference of exact replica from DVD-9 source compressed to DVD-5, anyone know about upscaling? I know they can't exact upscale to 1080p, I dont have blu ray player to compare it with....
So if anyone knows how upscale really works with compressed DVD-5, please help me out.
When you say increase quality, are you talking about
"Enable Overlapped I/O - this may increase ripping performance" ?
there are alot of variables with compression and picture quality. take a Sony 60" SXRD (like I have) you want to keep the compression at 75% to 80% or above. watching it on say a 31" CRT compression at 55% to 60% you will not notice a quality/picture loss.
you best choice would be to use an encoder like DVD Rebuilder doing the movie only transferring it to a DVD-5 SL blank(the picture quality is perfect using this program)
There's a basic description for upscaling in the glossary section, just click the glossary tab at the top of the screen.
In regards to comparing a 1080p upscaled image to blu-ray... there really is no comparison. The picture quality of blu-ray is so good because there's 5 times the information in the video stream alone.
Upscaling is really an alternative to having to spend an arm and a leg just to get better picture quality on a large hd television. I too had questions about how good a compressed upscaled dvd would look, there really isn't any difference from the original when upscaled (provided the compression is within reason).
The quality enhancements I was referring to are the settings in shrink after you click backup. Make sure (deep analysis) is selected along with the (high quality adaptive error compensation) sharp is the default setting.
There are many older much more descriptive and technical threads regarding upscaling, the different settings in shrink, and the comparison of blu-ray vs. a quality upscaler. use keywords to search for them, it may take a little while to find what your looking for but it's well worth it.
