BTW, anyone know how to export a movie from Adobe that is not letterboxed? It only seems to happen when I export something from Adobe, as the Anim8or version w/o sound is not letterboxed.
i've never used premiere (although i have used several other editing programmes), so this is just a guess off the top of my head, but: if you rendered from anim8or at the default 400 x 300 resolution, premiere might have letterboxed it because it was set to output in a higher resolution eg. 720 x 576, and you have a 'keep original resolution' setting turned on somewhere. if that's what it is, then the control to turn it off should be either in general program options, or in the right-click menu for the individual clip, i think. alternatively, you could find out what resolution premiere is outputting at, and render from anim8or at the same resolution.
i could be completely wrong, of course, but that's my best guess. hope it helps. nice first clip btw
