4:3 to 16:9
I am looking to convert a stretched piece of footage at 4:3 to 16:9 and i would like to do it without having to eyeball it… any ideas?

There are really only two good ways to have 4:3 video exist in a 16:9 composition. One is to have it pillar-boxed, meaning leave black bars to the right and left sides of the footage; just import the clip into the composition and leave it be, really.
The other is to scale it all the way up to meet the left and right edges of the frame, filling the entire screen but cropping the top and bottom of the frame. Doing it this way through the host app can cause the image to soften since you are scaling the pixels without a scaling algorithm.
You won’t gain anything from stretching the image to fit the 16:9 aspect ratio, you’ll just end up getting a severely distorted image.
If you are going from NTSC D1 or DV to NTSC D1 or DV Widescreen, you can leave the clip as is in the composition, or scale it up by a factor of 133.33% to fill the frame and crop the top and bottom. The 133.33% also works for going from PAL to PAL widescreen.
