I have been handed a VNT file and I am trying to get anything I can out of it.
Exiftool can see a bunch of PNGs in there, great! https://gist.github.com/eeeps/3ebf194ed6f209c3fad43a98629517c2
But I haven't been able to figure out how to extract more than the first one, with -b. How to I export specific EmbeddedImages, or better yet all EmbeddedImages?

Hi Eric,
Try this:
exiftool -embeddedimage -a -b -W "%d/%f_%t_%g3.%s" FILE
- Phil
Phil!
It worked!
For mysterious reasons I had to delete the `%d/`:
% exiftool -embeddedimage -a -b -W "%d/%f_%t_%g3.%s" prod29550692_E22920216054_TQ_OD23_pp3s0x.vnt
Error creating /prod29550692_E22920216054_TQ_OD23_pp3s0x_EmbeddedImage_Doc1.png
(snip)
1 image files read
35 files could not be read
0 output files created
% exiftool -embeddedimage -a -b -W "%f_%t_%g3.%s" prod29550692_E22920216054_TQ_OD23_pp3s0x.vnt
35 output files created
But after that, it worked a treat. THANK YOU!!!

It probably should have been %d%f_%t_%g3.%s or %D/%f_%t_%g3.%s
The %d variable includes a slash, the result was dir//file. Windows cmd ignores that, but I'm not sure how that is handled on other systems.
Right. The "/" shouldn't be there. A double slash is fine on any system, but if there is no directory specified and %d is empty then the leading slash represents the root directory, which is the reason for the failure here.

Makes sense! Thank you.
One more, possibly very simple question. On line 22 (https://gist.github.com/eeeps/3ebf194ed6f209c3fad43a98629517c2#file-exiftool-embeddedimage-L22) of the output I posted earlier, there is a PNG in the "Root Directory", that is not in an EmbeddedImage tag. How do I extract that?
—eric
Hi Eric,
The embedded images are extracted from the root entry, so you are just seeing one of those.
- Phil
Makes sense, thank you!
I am being told there is some sort of 3D data hiding in this Vignette file, as well, of either the "planar" or "flowline" types described here: https://experienceleague.adobe.com/docs/dynamic-media-developer-resources/image-serving-api/image-rendering-api/http-protocol-reference/http-protocol-syntax/vignettes/c-ir-vignettes.html?lang=en
I'm assuming exiftool can't see or extract that -- I'm not even sure what format it's in -- but you've been so helpful in this thread I figured it was worth an ask.
Possibly (?) related; the `exiftool -v` output from a different Vignette file contains two tag names (https://gist.github.com/eeeps/ccb98767a08562855254bfb8cd7eeb15#file-exiftool-vignette-2-L73) (`VmtFile` and `PolFile`) that I don't see documented anywhere. Any idea what those are?
Thank you!!
—eric
Hi Eric,
Sorry, but I haven't seen the 3D data you mention, and I don't know what VmtFile and PolFile signify.
- Phil
Phil, no worries and many thanks. If you're curious I can ask if I can share this file publicly; if not, I understand that I've already taken up a good chunk of your time, and your help thusfar has been invaluable.
—eric
Sure, please share the file and I'll take a look at it when I get a chance.
- Phil
I'm not sure if I have permission to share the files publicly. I emailed them to you directly.
No rush, and no expectations of any reply. Thank you,
—eric
Phil,
Is there any way to extract the contents of VmtFile and PolFile using exiftool? Even if we don't know how to interpret them yet?
Thanks,
—eric
ExifTool deals with metadata only, not the actual file data.
