Video QuickTime – How to Reduce Playback Speed in QuickTime Player

How about this: It's not exactly what you want, but achieves roughly the same thing.

I seem to remember pre-OS X you could activate an app and keep it from being frontmost, but that appears not to be possible these days (or I imagined it.)

to replaceFrontQTPlayerWithFile(aFile)

tell application "QuickTime Player"
    activate

    try
        set frontDoc to front document
        close front document
    on error err number errNum
        if errNum is -1719 then
            -- There is no open document
        else if errNum is -10000 then
            -- Front doc exists, but does not really...
        else
            log err
        end if
    end try

    open aFile
    play front document

    -- Hide QTP
    tell application "System Events"
        keystroke "h" using command down
    end tell

end tell
end replaceFrontQTPlayerWithFile


on run
    set unixFile to "/Users/diggory/Music/iTunes/iTunes Music/Music/Underworld/Oblivion With Bells/01 Crocodile.m4a"
    set macFile to POSIX file unixFile
    set fileRef to (macFile as alias)
    my replaceFrontQTPlayerWithFile(fileRef)
end run

Interesting question. One would assume if you record the presentation of a Keynote, all visuals would be recorded. Turns out it’s not.

I tried myself, and any Quicktime loop is only exported once. Bug? In the meantime, you could modify your Quicktime move to play several times in a row.

You can do this in Quicktime Player 7 (everyone should have it), by selecting all (CMD-A), copying to the clipboard (CMD-C) and then pressing paste (CMD-V) several times in a row. Save the movie in place, it will be virtually the same file size. Hope this helps!
