Recently upgraded from OS X (10.5) to OS X (10.6).  .MOV files played fine in Quicktime before the upgrade.


MacBook Pro, Mac OS X (10.6.8)

I recorded the movie using a camera, and the file plays on the camera as a movie... I'm stumped.

Then I suggest you compare the size of the playing file on your camera with the size of the non-playing file on your computer—they may not be the same. As QTKirk indicated, 40.37 KB seems unreasonable for any normally encoded non-anamorphic 1280x720 MPEG-4/AVC file more than a few frames long. For comparison purposes, a typical 1280x720 JPEG photo compressed to its smallest file size setting on a Mac would have a file size on the order of 100 KB. Other ways to look at your file would be...

 

a) if it is one second long, then its data rate is on the order of 322.96 Kbps

b) if it is two seconds long, then its data rate is on the order of 161.48 Kbps

c) if it is three seconds long, then its data rate is on the order of 107.65 Kbs

 

etc., etc., etc. which is unheard of for any reasonable amount of quality for 1280x720 HD dimensions in this compression format.

    Snow Leopard includes QuickTime X (ten) and it doesn't support many older codecs:

    Thanks for the suggestion; regret it did not help.  I downloaded and installed QuickTime 7 and I get the same outcome; the file opens, I can see the movie, but when I click on the play button, nothing happens.

    Open the Movie Inspector window and report what it says about the file.

    That data size suggests the "movie" is just a still frame.

    I recorded the movie using a camera, and the file plays on the camera as a movie.  Also, i have other movies that I had recorded with the same camera, and they played in QuickTime using OS X 10.5.x.  It was only after upgrading to OS X 10.6.8 that I could no longer play these movies.  I'm stumped.

    Jon:  Appreciate your help.  I had been 'exporting' the file from iPhoto, which apparently resulted in one frame of the movie instead of the whole movie.  Instead, I copied/pasted the file to my hard drive, and the whole movie resulted (which is a much larger file and also plays correctly in QuickTime).  What I can't explain, however, is that .mov files are now playing correctly in iPhoto, and they were not doing that when I posted the question initially.  Again, thank you for your help.  Joe

    If edited by Premier in compression formats not natively compatible with QT, then either export the edited results to compression formats that are QT compatible or use a player that supports the data in its native form. Since you have not provided any specific information regarding the codecs, settings, player, or system in use, all we can do here is provide this general response.
