Introduction

This document covers the RV 4.0.10 release, the forth non-beta release of RV 4.0 (complete release notes here).

Version 4.0 of the RV product line is built on a new evaluation and rendering architecture designed to greatly increase the flexibility and performance of our applications, and in particular to support features like:

  • More flexible color control (linearization to display).

  • Native OpenColorIO support.

  • "Quality Control" views and other "diagnostic" shading.

  • Compositing and image processing in linear floating point

  • Onionskinning and other blend modes for diagnosis and review.

  • Editorial transitions.

  • More flexible stereo support (stereo split/merge, stereo windows, etc).

  • Improved inspection tools, including histograms, targeting arbitrary stages of the color pipeline.

Some of these features have already been added, but out first goal was to ensure that no functionality has been lost in relation to the RV3 series (the latest RV3 release is version 3.12.20).

To that end, if you find a crash or other problem with RV4 it’d be wonderful if you could first

  1. Check that it not present in RV 3.12.20

  2. Confirm that the problem is not already listed in the Known Issues list (see below).

And then report it to us at support@tweaksoftware.zendesk.com.

What’s New in RV4 ?

Toolbars

RV now has two toolbars (above and below the main view) that are on by default and provide easy access to commonly-used features including:

  • Session navigation: select views, and go backwards and forward in view history.

  • View control: fullscreen, framing, background style, stereoscopic viewing type.

  • Color channel selection and per-device display conditioning control.

  • Buttons for commonly used tools: ImageInfo, Annotation, Session Manager, Timeline, Timeline Magnifier.

  • Playback controls and audio volume

The toolbars are on by default, but can be hidden (from the Tools menu) and this state will be remembered as a preference.

Per-Device Display Profiles

The Top Toolbar has as it right-most element a menu with the name of the current display device. Each display device now has it’s own display conditioning pipeline (transfer function, color primaries, etc). When you have configured a given device to your liking, you can save the Display Profile (View→CreateEditDisplayProfiles…) and assign them to that particular device (or all devices supported by that Video Module, or all devices) on the Video tab of the Preferences.
