mrv2 v0.7.5

v0.7.5

Playlist and Editing

This is the first version that supports some basic editing and improves upon
the playlist panel by making it interactive.

• The Playlist panel's functionality has been simplified. It is there only to
  create an empty track or start a new EDL with one clip from the Files Panel.
  The in and out points are respected when the clip is added.
• Added an Edit/Frame/Cut, Edit/Frame/Copy, Edit/Frame/Paste and
  Edit/Frame/Insert to cut, copy, paste and insert one frame (video and audio)
  of any media. Currently, it does not support transitions, that are removed.
  As soon as one of these commands is used, a new EDL is created.
• Added an Edit/Slice to cut a clip in half at the current time location.
• Added an Edit/Remove to remove the clips that intersect the current time
  location.
• Added Drag and Drop functionality to the Files Panel into the Timeline
  Window as well as to the Playlist panel to add clips and create an EDL.

  Plug-ins are defined, like:

  class Plugin:
      def hello(self):
          print("Hello from plug-in!")
  
      def menus(self):
          menus = { ("New Menu/Hello", self.hello) }

mrv2 v0.6.1

v0.6.1

  .otio files to specify the layer to load.
• Fixed a refresh issue on color lookups that would show the previous frame

    multipart openexr). Then, open the Files Panel and select the clip and
    layer to use.
  • Open the Stereo Panel and select the Input to "Image". That will clone
    the clip and select the opposite view (ie. right if you selected left).
  • Choose the Output for the Stereo 3D (Anaglyph, Checkered, etc).

• You can also use the Stereo 3D Panel with two clips (movies or sequences),
  but you need to set it manually.

  • Open the Files Panel, load the two clips. Select one of them.
  • Open the Stereo 3D Panel, select the other clip. Then select Input as
    "Image".

  refresh the cache. This is useful when viewing a partially rendered
  sequence.

• Made thumbnails in Files, Compare, Stereo 3D and Playlist panels show the
  actual layer (color channel).

• Made timeline thumbnail reflect the actual layer (color channel).

• Allowed saving annotations to a PDF. Both picture thumbnails as well as
  text notes are saved.
