OTIO support

RV now supports reading OpenTimelineIO (OTIO) files using a package that is installed and loaded by default. All schemas available in the current version (0.14) of OTIO are supported. All sources, stacks and tracks created will be added into the current RV session and will be accessible through the UI where, after import, the view will be set to the highest-level node created.

For reading custom OTIO schemas, a hook system that integrates with the native OTIO hooks is provided allowing schemas to be translated into RV nodes. The hook system can also be used to call a pre- or post-hook whenever a particular OTIO schema is being processed for custom handling of native schemas or their metadata.

Python 3

  • RV now uses Python 3 by default.
    To force RV to use Python 2, set the RV_PYTHON2 environment variable.
    e.g. export RV_PYTHON2=1
  • Added support for menu items defined in unicode.

QT 5.15.3 Update

As we adopt QT 5.15.3, we will be dropping support for macOS 10.13 in RV 2022 as there are compatibility issues between the two.

Progressive Source Loading

Two new RV commands were added:

  • setProgressiveSourceLoading()
  • progressiveSourceLoading()

setProgressiveSourceLoading(bool enable)
Turn on/off progressive source loading

Default=false unless
overridden on the command line with -progressiveSourceLoading 1
via the RV_PROGRESSIVE_SOURCE_LOADING environment variable

progressiveSourceLoading() can be used to inquire the current progressive source loading state.

Note: this command affects the behaviour of the following scripting commands:
addSource(), addSources(), addSourceVerbose(), addSourcesVerbose().

When progressive source loading is disabled (default), the sources are loaded synchronously.

You can expect this sequence of events:

  1. before-progressive-loading
  2. source-group-complete media 1
  3. source-group-complete media 2
  4. after-progressive-loading

When progressive source loading is enabled, the sources are loaded asynchronously by following these steps:

  1. RV creates a movie placeholder in the graph called a movieProxie which has a default duration of 20 frames.
  2. It dispatches the actual loading of the media as a work item to a pool of worker threads.
  3. Once the media completes the loading operation, the movieProxie placeholder is replaced with the actual movie.

You can expect this sequence of events:

  1. before-progressive-loading
  2. before-progressive-proxy-loading
  3. source-group-proxy-complete media_1
  4. source-group-proxy-complete media_2
  5. after-progressive-proxy-loading
  6. source-group-complete media 1
  7. source-group-complete media 2
  8. after-progressive-loading

Note that enabling progressive source changes the way you need to approach your scripts.

To illustrate this point, let’s consider the following example:


When progressive source loading is disabled (default), the script will behave as expected ; the source will be loaded and the frame rate will be set to 60 fps.

When progressive source loading is enabled however, the source will be loaded asynchronously, the frame rate will be set momentarily to 60 fps, and then it will be set to the source native frame rate once the source is loaded.

When using this progressive source loading to increase the responsiveness of the app, you’ll now need to call the FPS set on the after-progressive-loading event to ensure loading is complete before setting a property. This will ensure that you can benefit from the feature while also ensuring your code runs correctly.
