I am using Windows Live Photo Gallery on Windows 7 to manage my photos and video clips from camera/phone. If I import photos/videos from camera, it is smart enough to rotate as necessary, but I have some old stuff from iPhoto which is not rotated and I'd like to, specifically video clips.

AVI files have been easy to rotoate. Select the video, rotate. I am unable to rotate clips which are MOV or mp4. Is it a codec issue?

I bought Quicktime Pro to follow the simple suggestion provided here: How do I rotate video (MOV) file on Windows? but while it rotates it when playing in QT, it does not do so in WLPG.

I don't want to get Picasa just for this purpose. Any other ideas?

I have tested both the solutions in question 162259 and they seem to work fine, on my windows boxes I usually use ffmpeg. It isn't the answer to how to in WLPG, but this is a fantastic video tool for the toolbox especially if you want to crank out several files from a command line easily.

Does the output file have the same metadata (date/time)? – rpm Dec 30 '11 at 21:15
There wasn't much there to begin with, but the only thing I saw different was the height and width. – Dennis Dec 30 '11 at 22:17
I was referring mostly to the date/time of the clips. I had gone through a bunch of video clips and adjusted the date/time some months ago, would be painful to re-do it :-/ – rpm Dec 31 '11 at 16:56
??? Sorry, the mp4s I have laying around, or create don't have valid dates that I can find in the medadata so I can't say. – Dennis Dec 31 '11 at 18:35
