When I export from for example iMovie using Quicktime, the files created always have a creator named :TVOD. Doesn't matter if I create .mp4 or .mov.

I am running into problems that when trying to use the movies in a some other program, the files are not recognized specially with .mp4.

When I open such a file with QTplayer X and export it as movie, the creatortype TVOD has gone and I am able to use the movie.

 

My question: How can I avoid the creatortype TVOD when exporting with Quicktime (Pro) the first time ?

 

Thanks for any suggestions.

    Basically you can't until or unless Apple modifies the iMovie application. The "File Type" and "File Creator" property attributes are a legacy holdovers from iMovie's pre-OS X days which allowed System 9 and earlier apps to identify both the type of document and which app was used to create it. QT X, on the other hand, is an entirely new, post-OS X Leopard app designed for exclusive use under operating systems that do not use/require such lagacy identifications but, instead, write a "????" entry in the "File Type" and "File Creator" fields to maintain document compatibility with "legacy" apps. The fact that some of your files stumble when loading documents created by "legacy" based apps merely implies that they are not programmed for compatibility with such "legacy" documents.

     

    Basically, you can change the "File Type" and "File Creator" fields using almost any file property/attribute editor. In fact, some, like A Better Finder Attributes app, will even let you batch process files or folders rather than running the individual files through the QT X player.

    John,

     

    Thanks for your answer, I am starting to understand (I think) what is going on. To my better understanding (lack of my English knowledge I guess): I am a long tyme user, over 25 years) from Apple, most of the time migrated my system. Does your answer imply that when I would "uninstall" QT 7 Pro, this would also avoid the problem or will everything created by Apple at this point of time contain the File type and Filetype creator ?

    You don't have to uninstall the QT 7 Player whether keyed or not keyed for "Pro" use. What you need to realize is that QT 7 Pro will not change the "File Creator" code whether you save the file or export it using QT 7 Pro. It simply passes the original TVOD "File Creator" code on to newly created file container and may or may not change the "File Type" code depending on the new file container type.

    For example, as depicted in the above image, the original MP4 file created by iMovie '11 ("New Project Test.mp4") shows that the "File Creator" app was iMovie (TVOD) and the "File Type" is an MP4 (mpg4) file type. If i then re-export the file using the QT 7 Pro "Movie to MPEG-4" export option, then the creator and file codes remain unchanged because QT 7 passes the "TVOD" code on to the newly exported file ("New Project Test QT7.mp4") and the target file container remains "mpg4" because the file container is still MP4. On the other hand, if I simlpy use the QT 7 Pro "Save As..." option to resave another copy of the original file, then the "TVOD" creator code is still passed on to the new file but the file type is changed to read "MooV" indicating the data was saved to an MOV file container. On the other hand, if I duplicate your work flow and save or export the original iMovie file using the QT X Player, then both the "File Creator" and "File Type" codes are changed as indicated above.

     

    I should also note that I do not know what code (if any) is actually written to the QT X Player file output since the entry varies depending on which utility I use. For instance, while A Better Finder Attributes indicates displays "<none>" in both entries (which may only indicate the entries are empty), the File Properties Editor utility displays "????" and, to further confuse matters, if I use A Better Finder Attriputes "Remove creator and type" option, both of these utilities display "----" for these entries.

     

    All I was trying to point out was the fact that you can save time by simply batch processing your iMovie files in one of these property/attribute editors rather than using either QT X or QT 7. In fact, it also saves file space since these utilities write the changed data back to the original file instead of creating a new one and then you can use the modified files in whatever apps you say do not like the "TVOD" creator code.

    Hello John,

     

    Thank you very much for your comprehensive reply. I really appreciate you've taken the time and effort to explain things in more depth to me. I have a much better understanding now of what is going on and I will indeed, for the time being, use a utility to change filetype and creator.

    Hopefully Apple will modify things soon.

     

    Thanks again
