...Does anyone know how to change this so my movie files open in 16x9????
I have put Quicktime 7 back in my dock and these movies open fine in the old Quicktime 7.
Any help would be appreciated.
Thanks

    A specific solution would depend on you specific problem. Since you have not told us much here, I can only guess at your problem. This situation is most commonly caused by editing/modifying/copying a PAR encoded file using a work flow that loses the PAR flag/value. In these cases older applications like QT 7 normally contains four separate pieces of "size" info -- the dimensions at which the content was originally encoded, the proper aspect ratio playback dimensions (usually in parenths), the "normal" playback dimensions, and the "current" playback dimensions. QT 7 always plays back the content using the "Current" dimensions which you say remain correct. So I assume your is an anamorphic file which has lost its flag and is being played back in a ewer application like iMovie '08/'09 or QT X. These applications ignore the "Current" dimensions embedded in the file and rely on the anamorphic setting for playback. Lacking the proper flag/value, these applications automatically fall back on the 4:3 aspect ratio default for playback. Basically, you have three options: 1) use a different work flow which retains your original file's PAR setting, 2) re-encode the file that has lost its PAR setting so you can use the new file in whatever application is causing the current problem, or 3) use an older application like QT 7 or iMovie HD which rely on specified playback dimensions that can be user modified if need be.

    Hi Jon,
    Thanks for your reply.

    Just to give you more information, I'm using a Panasonic p2 camera and transferring files to quicktime to edit in Final Cut Pro. When I open an old (pre Snow leopard) quicktime file it opens in a 4x3 quicktime 10 box.

    From your reply I don't really understand option 1 "use a different work flow which retains your original file's PAR setting". What type of workflow are we talking about here?
    Option 2 is impossible because the p2 cards have been wiped everytime I transfer to make way for more filming.
    Option 3 sounds like my best bet. Just drag the file down to Quicktime 7 in my dock.
    Thanks again Jon.

    Not sure what you mean by "transferring files to QuickTime." If you mean you are converting files manually, then use use a QT target format/setting that retains the proper aspect ratio. If you mean capturing directly from the camcorder, then change the capture setting (Easy Setup menu) to one that retains the proper aspect ratio. (Sorry, not familiar with your specific camcorder model.)
