importing avi and mp4 files into iPhoto
I just finished importing my PC photo library into iPhoto and I ran into a snag.
iPhoto does not import video files in *.avi or *mp4 format.
On my old PC photo library, I have video clips taken into mostly avi format with older digital cameras, and which are stored in the same photo directories by date. When I realized that I could not sync avi files to my iOS devices, I used a conversion program to convert the the avi files to mp4 format, and was able to sync these to my iOS devices.
Now apparently iPhoto does not recognize these mp4 files. I would like to have my video clips in iPhoto so that I can sync them as needed to my iOS devices through iTunes and also sometimes use them for video editing in iMovie. Within iMovie, I see where there is a link to the iPhoto video library... so somehow I have to get these into a format recognized by iPhoto.
Can anyone recommend a method that will accomplish this? I assume I will have to convert the avi/mp4 files to some other format. Is there a utility that will extract out the video files from my hundreds of photo directories and let me convert them to the accepted format by iPhoto, preferably keeping the time/date stamp intact?
