If DGIndex reports my VOB as 100.00% video, does it need to be IVTC'd still?

There's no pulldown flags, but it's an interlaced video:
Code:
Width                                    : 720 pixels
Height                                   : 480 pixels
Display aspect ratio                     : 4:3
Frame rate                               : 29.970 (30000/1001) FPS
Standard                                 : NTSC
Color space                              : YUV
Chroma subsampling                       : 4:2:0
Bit depth                                : 8 bits
Scan type                                : Interlaced
Scan order                               : Top Field First
Not sure to apply IVTC or just use QTGMC/deinterlace?

DGIndex does not report video % per se; it reports film %, which really just means how much percentage of the stream has soft 3:2 pulldown. And scan type Interlaced does not necessarily mean the content is interlaced.

The only way to be sure is to step through the fields:

Yep well stream content flags/info aint always gospel truth nor even present, sometimes best guess is all that one can do.

It could be film with hard pulldown, or it could be pure 60 distinguishable images per second, or it could be a mixed-framerate edited-on-tape freakshow, or it could be a Lovecraftian eldritch abomination like the early seasons of South Park. The only way to find out is to bob it.
