DGIndexNV and DGSource are packaged as DGDecNV, and it is available for free starting on April 26, 2021. You can download the package from here.

This page shows how to register DGDecNV in StaxRip using the macro %settings_dir% to preserve the original program tree structure.

Unzip your copy of DGDecNV

1. Click on Tools > Folders > Settings and go to Plugins > Dual.

2. Unzip your copy of DGDecNV folder there.

So your DGDecNV folder becomes %settings_dir%\Plugins\Dual\DGDecNV.

Use the default x64 build and don't forget to rename DGIndexNV.exe.manifest~ to DGIndexNV.exe.manifest. This makes the generated dgi file encoded in UTF-8.

Register DGSource as a source filter

1. Add DGSource in AVS Filters > Profiles

2. Under the [Source] section, add the following lines with an empty line above and below respectively:

DGSource =
    LoadPlugin("%settings_dir%\Plugins\Dual\DGDecNV\DGDecodeNV.dll")
    DGSource("%source_file%")

※ Alternatively, you can incorporate hardware filter options (for deinterlacing/IVTC-ing) provided by DGSource as follows:

DGSource =
    LoadPlugin("%settings_dir%\Plugins\Dual\DGDecNV\DGDecodeNV.dll")
    # deinterlace: 0/1/2 (default: 0) (Nvidia PureVideo Deinterlacer)
    # 0: no deinterlacing / 1: single rate deinterlacing / 2: double rate deinterlacing (bobbing)
    # fieldop: 0/1/2 (default: 0)
    # 0: Honor Pulldown Flags / 1: Force Film (IVTC NTSC 3:2 pulldown) / 2: Ignore Pulldown Flags
    DGSource("%source_file%", deinterlace=0, fieldop=0)

3. Go to Tools > Settings, and register DGSource as a source filter for dgi.

For VapourSynth, switch to the VapourSynth mode and repeat similar steps as follows:

DGSource =
    core.std.LoadPlugin(r"%settings_dir%\Plugins\Dual\DGDecNV\DGDecodeNV.dll")
    clip = core.dgdecodenv.DGSource(r"%source_file%")

Or alternatively, incorporate hardware filter options (for deinterlacing/IVTC-ing) provided by DGSource as follows:

DGSource =
    core.std.LoadPlugin(r"%settings_dir%\Plugins\Dual\DGDecNV\DGDecodeNV.dll")
    # deinterlace: 0/1/2 (default: 0) (Nvidia PureVideo Deinterlacer)
    # 0: no deinterlacing / 1: single rate deinterlacing / 2: double rate deinterlacing (bobbing)
    # fieldop: 0/1/2 (default: 0)
    # 0: Honor Pulldown Flags / 1: Force Film (IVTC NTSC 3:2 pulldown) / 2: Ignore Pulldown Flags
    clip = core.dgdecodenv.DGSource(r"%source_file%", deinterlace=0, fieldop=0)

Register DGIndexNV as a preprocessor

Under Preprocessing in Settings, register DGIndexNV as a command line demuxer.

You can create 2 types of preprocessors with DGIndexNV depending on the input file types.

Index, No demux

Command: "%settings_dir%\Plugins\Dual\DGDecNV\DGIndexNV.exe"

Arguments: -i %source_files_comma% -o "%temp_file%.dgi" -h

※ Note: you can add the option to demux all tracks (-a) (and change the Demuxer Name) depending on your needs if you want to demux all the tracks regardless of the demux settings in Options.

Index & Demux

Command: "%settings_dir%\Plugins\Dual\DGDecNV\DGIndexNV.exe"

Arguments: -i %source_files_comma% -o "%temp_file%.dgi" -a -h

You can give a higher priority to DGIndexNV in preprocessing specific input file types by moving DGIndexNV items up in the list.

And of course you can activate/deactivate DGIndexNV by checking/unchecking the DGIndexNV preprocessor items.

Depending on your situation, you may want to add additional input file types. See this.

★★★ CAVEAT ★★★

You need to put mkvextract over any other MKV handler (like DGIndexNV) in order to demux tracks and other data from an MKV input properly as set in (Project) Options.

For example, even if you set Show Dialog in audio demux or subtitles demux in Options, you'll not be able to see the dialog if you put DGIndexNV over mkvextract (and thus DGIndexNV has priority over mkvextract in handling MKV files) when the source filter is set to Automatic. Therefore, put DGIndexNV below mkvextract to deal with MKV demux correctly.

In the same vein, if you want to demux MP4 files properly as set in Options, put MP4Box: Demux over any other MP4 handler such as DGIndexNV.

Register DGIndexNV GUI as a menu (optional)

In order to launch DGIndexNV GUI (separately) from within StaxRip, you need to register it as a menu.

1. Click on Tools > Edit Menu....
2. Under Apps > Indexing, use menu bar icons to copy and paste DGIndex.
3. Drag it to adjust its location, and modify its settings as follows:

Text(=App name): DGIndexNV (your choice)

Shortcut Key(optional): Ctrl+Alt+I (your choice)

Command: ExecuteCommandLine

Command Line: "%settings_dir%\Plugins\Dual\DGDecNV\DGIndexNV.exe"

Working Directory: %source_dir%
