Perhaps I should say, “Should this work?” I'm presently running SL on an I-Mac.
Could I download the DMG for Aperture 3.3.2 but not install it. Then in a couple weeks when I install ML over SL, could I then simply install 3.3.2, or should I have ML installed before I download 3.3.2? I have a wedding to shoot in 3 days and don't want to take any chances on having my present system on the fritz.
Adding timecode to your production can greatly simplify syncing multiple cameras, audio recorders, slates, iOS devices, and even GoPros on set.
