After moving to Snow Leopard (I believe that this is where it began) my renders have failed to work properly. They render out at double speed with the remaining 50% of footage as black. The same thing happens when I export to Quicktime Movie with "use current settings". Everything works fine when I export using HDV-1080i60. It's almost as if it thinks my footage is another format.
Can anyone help me? Is there any way I can set the codec for the renders?
