Running AC 13 on an IntelMac using Snow Leopard.
I don't do a ton of rendering, but have made a fair number of quick fly-through movies for clients in earlier version of AC without any problems.
Did a quick movie of a complicated roofline for our structural engineer, and although I did everything like I had before, and set it to export "Quicktime Movie", quicktime isn't recognizing the file as openable.
If I select "play" in the "Fly through" settings instead of "save" it plays just fine.
I tried opening it with an older version of quicktime, and a couple of other programs without luck.
Any suggestions?
