Voice Over Assistant

(Blender python addon)

For voice-over recording, audio tracks are removed from the original video, and actors read a script to match the mouth movements onscreen. In order to do this, the text should be visually as close as possible to the video, and the timing of the text should be malleable.

Voice Over Assistant
Shows text over a video clip, used for assisting audio voice-over recording.
UI location Sequencer
Usage Click the Voice Over play icon in the Sequencer. Change the script, onscreen position, and text color.

Data You will need a script of text to display. At this point, it should be a simple text file, and all chars will be displayed.

Known Issues Still getting an error: "UnboundLocalError: local variable 'sub' referenced before assignment"


About the Script File
For the time being, the filename has to be manually entered in the function 'get_script_filename()'


Works in the Sequencer, but not in Preview mode (yet). Buttons appear in the Sequencer Header. Should be a Menu, but it's a Panel right now. I would like to make this into an addon, so any suggestions would be greatly appreciated.

TO DO:

ERROR
This code still produces the following error. Any ideas?
   Python script fail, look in the console for now...
   bpy.ops.text.run_script()
   Traceback (most recent call last):
     File "\Text", line 264, in draw
   UnboundLocalError: local variable 'sub' referenced before assignment
   location: <unknown location>:-1	


Some properties:

  • done
      voice_over_is_on = on/off
  • done
      voice_over_pos_x, voice_over_pos_y = on-screen position (X,Y)
  • done
      voice_over_text_color = text color
  • in progress Inprogress50.jpg 50%
      voice_over_script_filename = script filename
  • on hold
      voice_over_visible_chars = number of characters shown onscreen
    • Probably should be the maximum number.
    • Words are never divided.
  • on hold
      voice_over_font_face = font face
  • on hold
      voice_over_multiline = allow multiple lines
  • on hold
      voice_over_font_size = font size 12-24
    • Huge memory hit to change font size, since all oGL chars have to be redrawn.
