I was just tweaking some properties in the media encoder when I tried to switch to "only export a preselected range of my clip". In Premiere CS3 there was this box right below format called 'RANGE'. Where'd that go???
AME CS4 automatically uses your work area, whether it's set to your whole sequence, or only part of it. Simplifies the export process.
While the output range will default to the work area you can adjust the range using the triangles shown on the left hand lower portion of the export settings dialog box just below the preview screen. Move the top indicator to the desired “in” timecode position and then press the left triangle next to the screen size pull down menu – repeat for the out point only use the right triangle.
