Video noise on DVD?
 

hi there,

did you ever expect to get a noisy video
signal of a DVD?

probably not ?!?

I backuped a DVD (cinema movie of the
mid 90s) with a modified
352plus template and was unhappy
about the result and size. After taking a
closer look to the video I recognized some
weak background noise in the pic.

So I tried to activate the noise reduction
(10/2/30) and to my surprise the
filesize shrinked from 600 MB/h to about
450 MB/h at better pic quality.

Yes, it's well known that noise is
poison for MPEG but I really didn't
expect to get noisy signals from a DVD.

What's your experience about the necessity
to denoise DVDs?

Maybe it's worth to keep this in mind.

Obrigado

Oh yes!, I've seen some crappy DVD's :lol:
As I have an HDTV, I can see the flaws on many DVD's.
For example, the movie "Kale and Leopold", the mastering on most scenes is very poor. They used a crappy encoder. That movie is a candidate for TemporalSmoother(1,2) in the .avs script. It reduces the mpeg size about 400KB per minute. So yes, you need it on some DVD's.

Me too
 

I have to apply noise reduction to all my DVD captures (video coming through S-VIDEO cable, even). Without noise redux, I get distracting noise and blocks in the final MPEG. With noise redux, I get that jaw-dropping, near-DVD quality that everyone keeps talking about! :D

hey obrigado,

just wondering which noise filter you're using and is (10,2,30) the settings for it? I run across noisy dvds too but I use temporal smoother(2,2) for the worst cases
