Importing 16x9 SD VOB file cropped to 4x3

I've imported a couple of DVD VOB files into Premiere Pro. Copied first from DVD to external drive.

The existing DVD is 16x9 PAL. Plays fine (widescreen) in VLC.

Once imported, Premiere Pro displays the VOB files cropped to 4x3 - losing the right side of the original 16x9 raster. i.e. about a third of the right side of the image is missing.

It's being interpreted correctly as D1/DV PAL Widescreen 16x9 (1.4587) yet only shows a 4x3 portion of the clip both playing in the Source monitor and in a sequence.

Tried conforming the file to all the other Pixel Aspect options in 'interpret footage' just in case - no dice.

Literally every preset still does not show the right third of the screen regardless of the opotion chosen.

Also tried importing the whole 'Video_TS' folder. No change.

The original DVDs may have been 'recorded' DVDs rather than authored - as they were probably (I think) real time recorded from DigiBeta.

 

This is in Premiere 15.4.1. Also tried importing into Media Encoder 14.9.2 - same issue.

The DVDs are not copy protected.

Any thoughts?

Look at one of the vob files in MediaInfo. Some DVDs have unusual pixel sizes/ratios. 

 

How are you creating the sequence?

Thanks Stan, will check with mediainfo.

Sequence is our SD IMX preset for all SD programs (not that there are any anymore).

Also tried dropping the file into an HD timeline - still 4x3 and cropped on the right.

Also try dragging the vob to the new icon to create a sequence that (PR thinks) matches the clip.

Are you familiar with After Effects?

 

You could try importing the VOB files into an After Effects Project and they should show as 720-by-576 non-square pixels and that it's Separating Fields.  Drag and drop the VOB file onto the New Comp icon at the bottom of the Project tab.  Go into the Composition Settings and change the Frame Size to 1024-by-576 and the Pixel Aspect Ratio to "Square Pixels".  While the layer is selected in the Comp, choose Layer > Transform > Fit to Comp.  Assuming that the source footage is DVD-Vidoe PAL 576i25 Wide, it should appear as expected.  Save the AE project and then use Composition > Add to Adobe Media Encoder Queue to render files that you can easily edit in Premiere Pro.  I recommend going with QuickTime as the Format and ProRes422 LT as the Preset (if you're tight on drives space, use ProRes422 Proxy).  The result will be a 576p25 QuickTime ProRes movie.

While in AE, you may want to consider what's called "cropping for overscan".  That is, scale the footage up just enough to hide thin black bars that may be at the left and right of the picture as well as skew that may appear along the bottom.  Also, if the VOB source footage has Macrovision and you intend to record back to tape (rare these days, but still a possibility), you'll want to scale the layer up to about 10% anyway to be sure to crop the Macrovision out of the picture.

Thanks Warren,

checked out your idea and realised that AE & Premiere Pro were detecting a frame size of 540x576 rather than 720x576 which I failed to notice earlier.

Thanks Stan & Michael,

 
I failed to look closely at the interpreted file, while Premiere Pro and After effects (correctly) interpret Pal/DV16x9 non-square - the frame size is detected as 540x576 (not 720x576).
So that accounts for the missing right side of the image (180 pixels).
Neither PP or AE are able to display the image correctly. However the VOB files play and display correctly in QuickTime Player, Handbrake, VLC and Uniconverter. 
And all ’see’ 720x576 sized image (except handbrake which detects 1024x576).
 
Put it down to some weird formatting issue with the ASUS DVD recorders that (realtime) recorded the original DVD long ago.
 
Client just ended up using the existing DVD - so all is good.
Thanks again.

I'd still be curious as to what mediainfo shows for the source material. You'll see old threads on this same issue. 

 

I suspect part of the source of this problem is DVDs recorded, as you suspect these were, by DVR.

Known issue.

MOD/MPG interpreted wrong

 

If you still have CS6 use that. CS6 is much more forgiving then CC versions.

Or convert to Prores with PAR 1.0 (have to do the math for resolution).

It seems like that bug is over five years old. That is not good.
