media files. To determine which color space and bit depth your video interface
supports, see the documentation that came with the interface. For more information
on which filters and transitions support 10-bit resolution, see “

sequences by

performing calculations in 32-bit floating-point number space. Compared to 8- and
10-bit integer calculations, 32-bit floating-point numbers have an extremely high level
of precision, which helps to avoid rounding errors that can accumulate as you add
more layers to a composite or add multiple filters to a clip. In most cases, you should
choose to render your sequence using 32-bit floating-point space (called high-precision
YUV
) for final rendering before output or export.
