I'm shooting a project in 4:3 on a GL2 with the 16:9 guides on so that at the end of all of my editing I can slap on the Widescreen filter, hit render and walk away for a day. When I'm done I would like to be able to view it on widescreen TV's without the black bar. Is there away to export the movie in 16:9 so when it's burnt to a DVD it is read as such? There was a topic earlier on this but it the answers were unclear to me.
You're dealing with widescreen apples and oranges. FCP's widescreen filter just puts black bars top and bottom, where as widescreen tvs use the full 4;3 frame, but with a different pixel aspect ratio to account for the different picture aspect ratio.
So, rather than applying the widescreen filter, go into the basic motion controls and distort the picture (so it looks sqeezed) and the top and bottom porion of the image that you can matted out in the gl-2 is off the canvas (because the video track is now too long)
Does that make sense? Now, depending on the dvd you're making, there's a whole nother bunch of issues that come into play. They probably deal with them in your instruction manual.
