Blackmagic Cleans Up Davinci Resolve in 15.1.2 Update

It wasn’t that long ago that Blackmagic updated the DaVinci Resolve, providing version 15 with some great new features. Now, two weeks later, version 15.1.2 does a little house cleaning and addresses a few bugs.

This software update addresses issues with running DaVinci Resolve on case sensitive drive volumes, improves stability on systems running CUDA, makes live save during remote grading sessions more reliable, properly premultiplies RGBA images when using OpenFX plugins. This update also improves Blackmagic RAW setting functionality, makes ResolveFX more reliable on the color page, addresses issues with Fusion paint, Fairlight audio, and dozens of other general performance and stability issues. – Blackmagic Support Site

  • Premultiplied RGBA images are processed properly when using some OpenFX plugins.
  • Source render cache now preserved when copying still or clip grades.
  • ISO selection is displayed correctly when applying changes to Blackmagic RAW clips.
  • Addressed an issue where adding a ResolveFX node to a clip during playback would display a critical exception message in the color page.
  • Addressed an issue where Fusion comps with paint tool applied would sometimes result in the first frame being black.
  • Copying clips in the Fairlight page no longer causes a random crash.
  • Dragging audio clips into track layers now works correctly on the edit page.
  • Dragging an audio clip with no mapped channels into the timeline now works properly.
  • Addressed an issue where track mute controls would sometimes show an incorrect automation state on the edit page.
  • Playing back smartphone clips in portrait mode is now more stable.
  • Addressed an issue where the delete through edit option would be incorrectly shown.
  • Addressed an issue where the photon validation options for IMF packages would not be displayed when Java Development Kit version 11 was installed.
  • Addressed an issue with the DCDM (P3D65 Limited) IDT in ACES 1.1 projects.
  • Addressed an issue where incorrect audio formats would be shown for muted audio tracks in the deliver page.
  • Rendering to ProRes 444 will no longer have chroma overflow artefacts.
  • Rendering Sony clips with Japanese file names now works properly on Windows.
  • General performance and stability improvements.

Additionally, Davinci 15.1.2 adds Audio Ducking using Sidechain in the Fairlight page Dynamics effect. Moreover, External Audio Processes gives users a round-trip mechanism which allows any clip on the timeline to be sent to an external application for audio processing. The updated file created by the external audio process is automatically added to the timeline as a new layer.

External Audio Processes can be added and managed in the Audio Plugins section of System Preferences. The round-trip process can be triggered from the clip context menu on the timeline.

Other improvements include:

Generating Supplemental IMF Packages

DaVinci Resolve Studio now supports generation of supplemental packages for IMFs when using Resolve’s Kakadu-based J2K decoder and encoder. Please note that you will need to disable the easyDCP decoder option in the Configuration tab of System Preferences to enable this feature.

With an IMF composition in the Media Pool, you can select “Create New Timeline Using Composition Playlist” in the clips context menu to create a new timeline. If the IMF package has any associated Dolby Vision metadata, it can be applied using an option in the creation dialog.

Any portions of the IMF timeline can now be replaced with source clips from the Media Pool. The timeline clip’s context menu has an option for not including the replacement clip for supplemental packages. There is an additional context menu option for selecting either the original or updated Dolby Vision analysis and trim metadata.

In the Deliver page, the “Supplemental Package” option can be enabled in order to generate the supplemental IMF using the new clips and the Dolby Vision metadata.

Performing Photon validation on IMF packages

DaVinci Resolve Studio now supports validation of IMF packages using Photon. In order to activate this feature, the Java Runtime Environment (JRE) will need to be installed on the machine.

Photon validation can be performed by right clicking on IMF packages in the Media Pool and selecting “Perform Photon Validation”. Additionally, there is a checkbox in the Deliver page advanced video settings to perform Photon validation after the IMF package is rendered.

One thing that is missing, however, pertains to Linux users, who have yet to get decoding and encoding of easyDCP formats. It’s not currently available.
