Hi,
I don't know if this would go in DV or better overhere,
please excuse me.
'

Question is, I have a 2 GB avi with DV-content (total is only 10min. of video)
I want to convert this to XVID.avi, but sofar I am NOT satisfied with the outcome using AGK 2.20
Therefore I turn to you guys for some advice on what XVID settings to use.

Funny thing is, 90 min. movies converted to a 700MB.avi file(xvid)
have pretty good quality, wich means each minute takes just 7.77MB of space.
When I calculate to use just 7,77MB per minute for my dv-content (2GB, 10min. playing time DV type-2 no audio)
I get realy sucky quality, why is ithis?

Even if I double the size for the DV-conent to 160MB, the quality
is still sooo shitty and certain details get lost real soon.
Also, movies ocnverted to 700MB xvid files get to keep around 600+ pixels
for the width, but my movie (dv wich is also dvd-quality to start with)
will only keep 351 pixels max. why????

I need some advice please :cool:

DV capture is far from DVD quality...
the problems you're experiencing are due to LOW compressibility of the video capture.
you have to use a much higher bitrate.

C&P from a thread long gone by:
DVD movies have scenes with mostly blurred background (no detail) most times only important things are shown with full focus in order to get the viewers attention to those points. Combine this with it being progressive / normally no shaking (except action scenes..) etc.. and you get a whole lot better starting material that will just compress better. This may not be the rule but movies just dont look like what people shoot with their camcorders ;)

In other words you're source just isnt as compressible as compared to most DVDs.
Either denoise/deshake etc. your source and/or use a higher bitrate.

Ok. that makes sense.

I never realized the lack in detail of backgrounds in dvd-motion pictures.
It all looked pretty sharp to me. Must be my eyes :)
And its true camcorder material never looks like a movie,
I wonder what filters or cameras they use to shoot big movies.
Isnt there a software filter that can make your cam-material look like the filters they use
for professional videoclips and movies??? (prob. a noob question)

More important question I have is, how do I denoise or deshake my
video to get better results?
I can send some 1 minute material if anybody (anybody) would be interested in helping me figure out what best settings to use for my dv-content?
But probably most dont have the time anyways. I just thought it wont hurt 2 just ask ;)
I'l google around and try to do my own homework as well :)

Any further replies or tips welcome.

Denoising, deshaking, etc, you should hit up the avisynth and perhaps analog capture forums, where those are pretty regular topics. The first thing that's asked is pretty much "sample plz" so uploading that would help a lot.

(Too bad the forum's search makes searching for more than one term impossible.)

There is always google search (http://www.google.com/search?q=denoiser+comparison+site:forum.doom9.org) :)

Oh Hey thanks!
I never noticed that subforum before.
So I can upload a piece of my dv content?
ah well i'll read up on that thread first

Thanks

Sometimes googling works great; but it sorts threads all out of order (I hate jumping to a likely thread just to find it's from 2002!), and it doesn't index everything. It's a decent supplement though.

You can upload a piece of it to, say, rapidshare or one of the other file upload sites around (I'm sure there was a sticky with a list of them...)
