Higher Bit Depth: 10-bit Video CPU Pipeline
What is "bit depth?" That is the number of colors or video brightness levels. 8-bit has only 256 values per color component, for example, red/green/blue. 10 bits has 1024 levels. Previously, 10-bit video sources were only partially supported using GPU Effects and only GPU filters. Without GPU Effects (CPU), in order to stay in thee 10 bit space, you could only use filters with the #10bit tag but no transitions or track blending/compositing. Now, we have ported many CPU video effects to support 10- and 12-bit video sources including transitions and track blending. Also, the #10bit CPU video filters also work properly with the experimental GPU processing. Not all of the video CPU filters have been converted; many of them come through another software project that does not support it. However, we were able to convert many for this release or at least mark them as safe for a 10-bit project.

Higher Image Quality: Linear Color Processing
Any mixing of pixels with a color space's gamma is not ideal, can cause color distortions, and is technically incorrect. This pixel mixing occurs whenever images interpolated, for example scaling, blurring, and sub-pixel positioning, as well as with track blending/composition. Previously, only GPU Effects and video filters in the GPU category operated in linear color. Now, there is an option to use it outside of the GPU processing. But when using the GPU, the handoff of the video from GPU to CPU now stays in the linear color transfer.

There is a new sub-menu in Settings > Processing Mode with options:

Native 8-bit CPU (fast, flexible)
Native 10-bit CPU (slower, better)
Linear 10-bit CPU (slowest, best)
Linear 10-bit GPU/CPU (Experimental)
Non-linear "native" options are still included because there is a signficant performance decrease when using linear (more conversions). We have a plan to improve performance for the next release. 8-bit is still included because it is more "flexible" by including more video filters. Of course, you can use an 8-bit video filter in a 10-bit, but the quality of the video clip or track will suffer a reduction in bit depth.
