Working with Adobe Premiere Pro
• Matrox custom Truncates the AC coefficients to the lowest whole
number when calculating the quantization coefficient. In some cases,
this setting may yield less artifacts in graphics.
$ From the DC precision list, select the bit-depth precision of the DC intra
block. The higher the DC precision value that’s used to render your video,
the more likely that the DC content will be increased at the expense of the
AC content in the encoded stream. This may result in lowering the overall
quality of the compressed stream at a specified data rate.
$ Select the Force frame-based DCT setting to render macroblocks as
frames rather than as fields. In some cases, graphics will yield less
artifacts if this option is selected.
