We often do some projects in 16:9, where we are forced to use some old 4:3 archive footage.
If we are in a hurry, we just capture the footage in FCP as 16:9, and then stretching the picture by 25-30% (only vertically)
It looks OK, but of cause not as good as real 16:9 footage.

The other way is to capture all the footage trough our Teranex Mini UDCSN
This will upscale the 4:3 to 16:9 with nice looking results – in two different modes:

Common Sides
Ensures that the left and right edges of the input image match the left and right edge of the output
aspect ratio. For example, if the input aspect ratio is 4:3 and the output aspect ratio is 16:9, the left
and right edges of the input image are stretched to match the left and right edges of the output. In
order to maintain correct geometry of the image, the input image is then stretched vertically as well.
This has the same result as zooming in on the image. While this method maintains correct geometry
and fills the entire output display, it also results in an overall loss of approximately 33.33% of the input information in the vertical domain. This loss of information is split evenly between the top and bottom of the image.

Flexview
This mode, available in 480i59.94 to 720p 59.94 & 1080i59.94 and 576i50 to 720p50 & 1080i50 up-
conversions, is a non- linear anamorphic aspect ratio designed for use when converting 4:3 material to
16:9 without the traditional distortion of a normal anamorphic stretch. Flexview leaves the center
portion of the image untouched but provides increasing amounts of stretch towards the edges of the
image, filling the 16:9 image without distorting the center action area.
