What's new in DaVinci Resolve 17.3


What's new in DaVinci Resolve 17.3, released on August 20, 2021?


Translated versions of what's new in the release notes are listed at the end.

"DaVinci Resolve 17.3's Wild Speed ​​~Summary of New Features~" is summarized in Vook by Blackmagic Design.

Isn't the main feature "improved performance on M1 Mac" and "compatible with ASIO standard on Windows"?
In particular, the optimization of the M1 Mac was also featured extensively on Internet sites that normally do not deal with video editing software.
It's nice to see the awareness increase through the new features. According to Blackmagic Design's official website, "The new processing engine makes 4K/8K editing and grading up to 3x faster on M1-equipped Apple Mac models!"

Among many other enhancements, Marker overlays are also visible during playback, the ability to move the playhead on the fly when using playhead mode in split screen mode, and automatic generation of gain keyframes when using edit selection mode. I hope these will help you soon.
