4) "Well behaved" MOV files have a moov atom, a trak atom for the audio and a trak atom for the video. But some files have more than one moov atom and multiple tracks. If that is the case, you can either stop now or make the changes to all the video tracks. Find the video trak atom, then the mdia child atom and then the mdhd child atom. The mdhd atom has 8 entries (p 62 of the QT file reference). The entries are Version, Flags, Creation Time, Modification Time, Time Scale, Duration, Language and Quality. Generally, the Time Scale is the frame rate, although not always, since it is relative to the number of frames and the Duration.

6) Save the file and open it with the QT Player. If the Movie Inspector shows the wrong duration and/or frame rate, you did it wrong.
I used the Dumpster program located here:

QuickTime Tools

and the directions above to edit a Canon 7D file. The Time Scale appears as "60000" for a 60fps clip. Setting this to "30000" give half speed, "15000" gives quarter speed, etc. Basically, it is 60.000, but the decimal is not shown.

It takes 2 seconds to open a clip, change this parameter, save and then test in Quicktime.

If you need slo-mo from a Canon 7D and don't have Cinema Tools, this will do nicely on a Mac. No frills, but works exactly as described. Completely reversible by re-editing the file.
