How do you extract just background image?

How do you extract just background image from a DVD? I've been taking a snapshot with PowerDVD but when you do that you get the buttons too, I want to just get the menu background image with no buttons thanks!

use DVD2AVI and save your *.VOB file as and avi extension. Then I use ACDSEE to open up the avi file, copy the image to the clipboard and save the image as a *.bmp, which I then load into scenarist.

Hi,

demux with VobRator or VStrip than extract an image with an MPEG Editor (MPEG2VCR) or Maestro.

Alternatively you can do a (short) DVD2AVI Project from the (unencrypted) Vobs; just a few seconds in length. Than import either the .d2v or a VFAPI AVI into AviUtil or VDub (or an Videoeditor which accepts VFAPI) and export from that. This is fast and works always.

There's no visible quality degration.

more simple

open you VOB menu with DVD2AVI. set color space to RGB and now you can make screenshot by pressing B or options->save BMP

denfert,

when using this method where does the bmp get saved to? I can't find it!

[denfert]

in the DVD2AVI folder

When using the DVD2AVI method you still get the buttons in the image so this doesn't work.

[denfert]

so , the buttons are in the image

the only possibility to remove them, is to use Photoshop.

[Commander XJL]

Thats what I've been doing but since the buttons are a seperate element there must be a way to extract just the image. Are you guys who posted the other methods sure they work?

I personally use DVD2AVI, then VFAPI to create an AVI. I then use VirtualDub's "Save Image Sequence" from the AVI file. By doing this, you can open a VTS_01_0.VOB (for example) file that has a full set of menu stills and write all of them in one action. VirtualDub will allow you to step through the file one frame at a time, and you can choose a start frame and frame count to save.

What do you mean by 'the buttons'? Are you on about 'play movie', 'scene slection' for example? If so, these aren't the buttons they are just text that is part of the image.

I don't understand what you want.

[jdobbs]

I think there's confusion is in the definition. The button image itself is usually a part of the background and can't be removed. The button area and any overlay images (like color changes, icons, etc.) are a separate element. There normally is no "background" without the image of the button (for example, the text that says "Play Movie" is usually a part of the background image).

[Arky]

Correct - the separation between button and background is only an illusion - it is actually part of the background - otherwise you wouldn't know there was a button there in the first place, to be selected! You may well have to add buttons as a subpicture image IN ADDITION to those integrated with the background, but this is only so as to create the illusion that the button 'lights-up' when you move the cursor over it. The duplication of button image is necessary so that the subpicture copy can be coloured differently ('highlighted').

I partly blame Spruce Up and DVDit! for this confusion, because the manner in which their authroing procedure progresses, MISLEADS the user into believeing the buttons are always a separate entity, which, in reality, they are not. They do not encourage the user to gain an understanding of the underlying processes in DVD-authoring and Playback (I firmly believe that one CANNOT truly understand DVD-authoring unless one also understands the tricks the DVD-specification uses during playback - the two levels of understanding compliment each other, and guide the authoring process).

If everybody authored with Scenarist or Maestro, I don't think this confusion would ever exist, since they demand the user to think and act in a more literal manner, than the "dumbed-down" consumer DVD-authoring-applications (I'm not referring to the users, just the software, before somebody takes offence!! :eek: )
