NuMenu4u Asset/Button stripping guide

The VOB Preview screen is broken into 4 sections; the Asset list, the Preview player, the AviSynth Script Editor and the Bitrate calculations.

Asset List

This is the area that will show all of the VOBIDs for each VTS menu that has been processed. Some information will also be written next to the VOBID, so you can see exactly what you can do. There will be 1 of 3 icons visible. A closed book represents that this VOBID has no buttons (like the VTS name), so is probably an intro into a menu. An open book represents that this VOBID has menu buttons present (like our example). A padlock represents a VOBID that requires CELLID processing (in which the text will say Requires CELL Processing) or it is being automatically removed (in which the case the text will say UnReferenced -> Pre-Stripped). If in your VIP options setup, you have set to Automatically Remove Warning/Intros from VIDEO_TS / VTS then non-menu VOBIDs will have the following text written Removing Warning/Intro.

The Preview Player will show the video and all subpicture buttons that have been found. The correct CELL and Subpicture positions are honored. Most menus have only 1 subpicture per Cell, however, some like Spiderman (R1) have multiple subpictures that change every few seconds. In this case the player would seem to flash a lot as each new subpicture is loaded.

As each subpicture is loaded the menu buttons will be displayed. The button routes will also be shown (UP, DN, LT and RT). Each route can be either displayed or hidden. Change the four colored buttons to do this. In this example I have disabled the UP and LT routes.

To turn off the routes completely press the button with the arrow in it, and the tick will change to a cross and vice versa. When this button is off none of the route buttons will be selectable.

Hovering the mouse over each button will display the actual button command. Again to turn this off press the button with the E in it. As above the tick will change to a cross and vice versa.

These are standard buttons for Play, Pause and Stop.

Here we have Previous Cell, Previous Subpicture, Next Subpicture and Next Cell. Depending on which Subpicture/Cell is playing will determine which of these buttons are selectable. Use these to advance through the video at only important intervals (i.e. a new Cell or Subpicture)

The Restore Button will repair any mistakes we make. Then we have the Show Command and Show Routes buttons. Finally the four buttons representing the four available routes.

A mouse click on any button in the Preview window will show this menu

Restore This Button to Original State will undo any changes made to the current button.

Remove This Button will delete this button from the menu - the button will now turn green

Make This Button AutoAction will force the button to be selectable without pressing Play on the remote - the button will now turn magenta. If a button was already set like this originally then it will show magenta on start up.

As with the above buttons, Button Commands - Visible / Hidden will show or hide the Button Commands. Button Links - Visible / Hidden the same. Current Button Command is the actual button command for the current button.

Depending on the current Cell / Subpicture will determine which of the four bottom options is selectable (this is the same as the Previous Cell buttons etc. above)

Search and Replace will show this sub menu. If you have changed or deleted a menu button then this new state should be copied over to the other Subpictures / Cells (If it is still present in these other ones). If you have changed just one button then choose the former (THIS) or if several buttons the latter (ALL), and then decide if you want this to be copied over This Cell Only or This Entire VOB. Most menus change at the Cell boundary, so copying This Cell Only is wise. The final option here is Pixel Threshold (+ or -). This is for where the authoring house used multiple Subpictures and altered the position of the buttons slightly. By default NuMenu4u will search for any buttons in the same position and of the same size + or - 5 pixels. Here you can change this threshold.

Restore All Buttons will give you the choice of restoring the buttons back to their original state. This can be for the current SubPicture Only, the Entire Cell etc. Pressing the Restore button above will show this menu also.

AviSynth Script Editor

To make any alterations to the AVS script type the new filter into the editor and press the Test Temporary Script button. If you are happy with this then press the Replace Actual AVS button. NB This cannot be undone automatically. You can of course rewrite it manually and then Replace again.

Here the various boxes tell you what the new DVD or Menu size is going to be if you re-encode and don't re-encode the video. The Total DVD Size includes the title files in their present size. Altering the bitrate will show you the new predicted sizes. You may well find that after removing warning screens, foreign language screens etc., that the overall size has come down to a point where the title files don't need to be processed. If this occurs and in the VIP Options you had selected Create ISO Image then NuMenu4u will complete but stop further processing with DIF4U and create an image file instead ready for burning.

If you decide to use the original video instead of re-encoding pressing the I've Changed my mind. Keep Original Assets will achieve this. Press again to reverse.

Half Size Preview Window will reduce the Preview window by half. This should never be needed.

Close VOB Preview to finish and Exit.
