Drag and Drop syntax

[ffrree]

Hi, I am an absolute newbie to this, so please excuse my silly questions.

My question is in relation to use the drag and drop feature, that's what I did,

1) I changed the name of exiftool.exe to exiftool(-rotation=90).exe.
2) I dragged the .mp4 file and dropped it onto the newly named exiftool
3) cmd window opens, then I can see the file I dropped has a .mp4_orignial file created.
4) but the "newly" created file had not been rotated 90 deg.
5) However, I run this command line syntax  " exiftool -rotation=90 file.mp4 works fine.

what did I do wrong ?

I copied your drag/drop name and created a copy of exiftool with that name.  I then drag/dropped an mp4 file onto it and viewed it with VLC. VLC displayed it properly rotated 90°.

Exiftool doesn't physically rotate the video, it just changes multiple tags that control how it's displayed. It's probable that the program you are using doesn't respect the tags that control how it's supposed to be displayed.
