Adobe&s latest update for Premiere Pro to version 13.1.3, released on July 12, brings several new features and improvements as well as numerous bug fixes. The improvements in detail: the HEVC performance on Macs has been optimized; the multi-channel audio mixing now allows up/down mixing of 5.1 from and to stereo using the Channel Mixer effect; there is more flexibility in exporting subtitle files; the graphic layers now have the same order in the Essential Graphics panel as in the effects settings window; the distortion stabilization is now more powerful and allows cleaning up footage from different handheld cameras or optimizing camera shake.
The stability of the following operations among others has been increased: program start, tutorial start, opening old projects, setting keyframe values and scaling, scrubbing, subtitling and freeform mode. Also a lot of bugs fixed.
Unfortunately the support for importing videos in MKV format has been removed. Adobe recommends the latest version of Intel and NVIDIA video drivers for Premiere Pro 13.1.3.
