Obviously the thread and also response from "joe4tune" was posted over 3 years ago but I just downloaded VLC Media Player, hoping to rotate a video emailed to me by my brother. However, I could NOT find the command to change the orientation. It is not
under "View", "Tools", or "Video". Or at least it's not OBVIOUSLY under any of those. I persisted because "joe4tune" was so convincing (plus I then read a very favorable review from CNET). Eventually I DID find it. Here's help for anyone reading this -
Select "Tools", then "Effects & Filters", then "Video Effects" and then at bottom left of that window is a "dial" which allows for intricate rotation. Very nice, but not intuitive how to get there. But it is open source and free so I'm really not complaining.
A suggestion would be to make it more intuitive maybe? Hope this helps someone.
(Oh and by the way - changing the orientation is a permanent change to the file ONLY if opened with VLC Player. So be sure to change your default or ensure you "open with" VLC player.)
