Quantscale and Scan type settings

[windtrader]

I noticed on a source DVD that the Qualscale=Nonlinear and Scan type=Alternate while the default advanced settings for CCE is Qualtscale=Linear and Scan type=ZigZag.

Should I be checking each source DVD and set the CCE values to match?

btw - I've no clue what these settings do; I just happened to notice there were different source and target values when scanning the VOBS using BitRate Viewer.

Try the CCE FAQ, Q7:

PD: This undoubtely belongs in Basic stuff. Use that for the next time.

Thanks for pointing me toward the CCE specific posts.

The reason I posted here is I am hoping to get more background from the DVD2DVD folks about why and what the rationale is for setting CCE values in DVD2DVD. DVD2DVD provides a few user selectable CCE settings but there are many others that are set to defaults or being directly set by DVD2DVD.

I understand CCE is a world unto itself but that is why I am using DVD2DVD: to get around having to know the "gory" details of CCE. That said, of those selectable CCE values that can be set in DVD2DVD to make a better video encode, I would like to learn those aspects.

Use templates, via the advanced dropdown in the encoder tab, so any special settings are easy to reuse. The conventional wisdom is uncheck everything in the quality box then set zigzag on and the progressive flag on for progressive source and Alternate only for interlaced source. Nothing else checked.

In video nothing checked except "add sequence endcode" and set M=3 and N/M=4. (although that is a subject of debate and discussion). These settings are what I have used with no problems.

Templates are accessed and created by just clicking on a checked template in the template menu item. Fairly self explanatory...Add, replace, delete. So just select the standard template so that it is checked, select it again, and you will be in the template creation area. Modify the standard template and change the name to "Progressive" and click add. If for use with RoBa, make a "progressive-roba" template with the "use existing vaf" checked.

I have a Progressive, Progressive-RoBa, and a Interlaced template. Those three do all the work for me.

DDogg,

Thanks for the template tip. I think there may be a problem with DVD2DVD 1.2.1 beta 1/2. In the encoder advanced setting panel, the progressive frames checkbox is NOT checked. This means output from DVD2DVD using the default settings creates VOBS that have frame type set to Interlaced. It seems if you are doing DVD to DVD backups, this should be defaulting to Progressive.

I know I'm not the first to use the default settings and I don't recollect much moaning about the output being screwed up. If frame type is set to Interlace, how much visual artifacting is going on? Although I've not specially looked for interlacing artifacting nor do I view DVD2DVD'd backups with a critical eye, the movies that have this setting don't have visual artifacts jumping off the screen.

I've tried to create a new CCE template by going into the advanced settings, checking Use CCE Template, and selecting the 0-Standard. It does not jump to a template panel or allow me to see, change any other CCE settings. I'm using DVD2DVD ver. 1.2.1 build 2.
UPDATE: I discovered you need to manage the templates from the TMPGenc application. No problem now. thx

Whoops, my bad. I forgot that templates are not allowed when CCE 2.50 is chosen in the path box. I have not used 2.50 in a long time and it slipped my mind. The suggestions above concern later versions.UPDATE: I discovered you need to manage the templates from the TMPGenc application. No problem now. thx I don't know what you meant by this.

Ouchie. I meant CCE, not TMPGenc.
Just to clarify - I CAN select CCE templates in DVD2DVD 1.2.1 build 2 with CCE 2.50. It's just that I can not create or modify the CCE templates directly in DVD2DVD; I have to go directly into CCE, set up the template, then go back into DVD2DVD and select it.

I will upgrade the CCE encoder just to get current and hunt around for a set of templates that are working for most.

thx

Just to clarify - I CAN select CCE templates in DVD2DVD 1.2.1 build 2 with CCE 2.50 Well I sure can't :) Are you absolutely sure you can? I am pretty sure if the cce 2.50 executable is selected in the cce encoder tab you can not access the template checkbox or dropdown. It should be grayed out.

As for changing template params, yes, that is done in CCE itself.

DDogg,
I sent you email with a screenshot of my system showing what I see and that I have the Use CCE template specified. This works with both 2.50 and 2.67 versions using DVD2DVD 1.2.1.

If we are in synch about the same thing, then we most likely have different versions of the program.

[DDogg]

Got it. I guess you must have to create a template above and beyond the standard one for cce 2.50. Perhaps there are no registry settings created by cce 2.50 for d2s to read without doing this? Anyway, you certainly can select a template for CCE 2.50 so disregard what I said above. windtrader, thanks for taking the time to send the screen shots.

DDogg,

You are right. Last night as I uninstalled and reinstalled DVD2DVD, I took a lot at the registry to see what it was storing there and might need to be cleaned up.

For 2.50, the stanard template 0 has a registry entry but no CCE values; so, it is a "dummy" and who knows what DVD2DVD does it runs with the standard 0 template specified. It probably should be reported as a bug. When you add a new one using CCE SP, it does add the new template values to the registry as one woule expect.

In 2.67, the standard 0 template has values and new templates are also stored in the registry.

Now, I just need to get those template values specified for my standard dvd-dvd movie copy to single DVD-R. :-)

And - I'll march back to the basic forum. Thanks for all the help over here.

One of the reasons I didn'y answer that part is I don't have a dvd burner, although I do test that part of the program sometimes. I still don't think "dvd compliant" is correct to use, but I'm not at all clear why. It is just in my head from somewhere. Maybe you can do a search for "DVD compliant" and "CCE" and find something definative. If so please let me know. In the meantime, I think I would not check dvd compliant, use FACAR and the standard progressive template settings we discussed. FACAR has a setting in it for DVD now.
