Hi Donald
.mp4 files may include the parameter "Rotation" (in degrees). After demuxing with DGdecNV this parameter gets lost, i.e. it is neither kept in the .dgi nor in the elementary video stream.
Would it be possible to include it at the end of the .dgi (similar to the resolution) ?
Mobile phone video clips can be taken in portrait or landscape (at 0, 90, 180, 270 degrees). Preserving the correct orientation is essential for re-encoding to avoid turned and flipped pictures (I think).

I just select three or four spots and compare the crop values
Me too. On really old restored movies, such as ones from Criterion, AR varies according to the found positives. It's really hard and time consuming but, hey, we are talking about masterpieces.

'Export to script' checkbox added to Cropping Tool in slipstream 164. Refer to the user manual for proper operation.

You can't tell what the required rotation is just by looking at the video? I'm reluctant to add container specific data to the DGI file.

Yes, I can always look at the video of course. However, when I want to automate the process it would be useful to have the the value automatically extracted.
I understand your reluctance though, so maybe I should better extract that value outside of DGindex; perhaps with MediaInfo or similar.

One little cosmetic: don't make the black borders appear again after closing the cropping window AND the script export is selected.

Oops, I screwed up your post by hitting edit instead of quote. Sorry. Feel free to edit it back to the original.

Thanks for the new suggestion. I'll do it for next slipstream.

There were only some congratulations for the good job you do every time.

Hint: add a "thank" button for posts we would like to thank. Dunno if technically possible for phpBB.

Hi. I haven't tested our latest release but may I ask how the cropping tool handle border % 2 != 0 ?
( Personally speaking, it should not be over-cropped? )
