best way to start?

[killer099]

hello

I have been ripping a little to divx, using flaskmpeg...
Now I am learning ripping to SVCD,
currently using DVD2SVCD(newest version).

I have been trying to rip "Iron Maiden: Rock In Rio", it´s about 2 hours long, så I make it to 3 CD´s@800Mb.
The problem is that when there is high motion(almost the whole film),
the picture gets very bad, looks like a very hard compressed JPEG-image or something, almost as the pixels gets very big...
(I think you get the picture?)

Så what to do? I have seen on this forum that people are talking about different filters, does them solve the problem?
WHich one is best, and are they hard to use/install?

best way to start? Is to not violate forum rules and make your tittle reflect the problem of your post.

Camcorder type material is extremely hard to make into a SVCD.
When I mean camcorder is when the camera moves alot and not just the actors. If you watch most movies the camera moves very little or slowly. In concerts and other similar types of video the camera tends to pan very quickly. This is much, much harder on the encoders to deal with and no filter I know of will really help with that.
I have made many attempts on this type of material and never had much luck. You could try using Temporal Smoother or something like that, but I still think the end result will be less then what you want.

For info on Temporal Smoother (often shortened to TS) do a search here, in the advanced forum and in the Avisynth forum.
There are new filters like Blur2 that might help, but I have never tried it. You may also want to ask the Avisynth guys as they are the king of filters and we just feed off them.

set your field order to Bottom First

Sorry, I wasn´t too clear. I didn´t mean that I have recorded it by myself, it´s a bough DVD(retail).

So the quality is very good when I look at the DVD using powerDVD or something, but when I ripped it, it gets very ugly...

If you use CCE to encode, you could try adjusting the image quality priority setting.

The Avisynth filter Fluxsmooth at its default settings increases compression without losing the details. It's also a bit faster than the popular Convolution3d.

No I understood. What I was saying is that material like concerts, Porno's, Girls Gone Wild, and the like have a ton of camera movement. Movies tend to have the camera still or move very slowly only the actors move.

In the case of a movie the encoder doesn't have to figure out the background as much since that tends to stay static more often. When the camera moves it has to think much, much harder and use a ton more bits to do the scene since everything is new. Mpeg works from a what is different thinking. If the area remains the same it doesn't rethink that part. When it changes it has too.

Look to see when the parts get really bad and try to determine if just the people are moving or is the cameraman moving the camera too.

You have about 40m on a CD, so try to increase the Max Avg in the Bitrate Tab.
Also see if it is interlaced...

[killer099]

Answering some questions...

I´m using Tmpgenc-free, newest version.
Is CCE better or?

And yes, the movies is interlaced, so I´m using
"smart-deinterlace".

There is one thing I don´t understand(propably my fault),
but markrb said that this kind of movies contains a lot of camera movement(and it surely does :-)), but the image quality is perfect on the dvd, why does it gets this bad when ripping?
Is it only because the limited bitrate?

And can somebody explain shortly what the "Field Order" setting does?

Please help me, really want to rip this dvd!

[markrb]

Is it only because the limited bitrate?

Mostly that is true. When doing even a high bitrate SVCD we are dropping the bitrate about 5X over the original.

Plus the DVD people have access to resources we just don't have. Most likely that was converted using very expensive hardware based encoders coupled with a very expensive software encoder. We are talking millions of dollars of equipment, not the thousands of dollars we use.

General rule of thumb:
CCE best for MPeg-2 SVCD video.
TMPG best for Mpeg-1 VCD video.

Keep in mind. More bits=better quality video = less time on each disc.
2 hours on 3 cd's is about the most you can do and still stay within the SVCD spec. If your player supports out of spec SVCD's (check www.vcdhelp.com ) then you might be able to go higher.

Yesterday I tried to rip a chapter again, using "Bottom First" on the setting "Field Order".
And I got much much better, but still there are parts that are are looking "big-pixel", so what´s the next step to go?

Using some filters or?
