VFX1 - DD1410: Brief 01- Altar Sequence, 001-449 First Thoughts

For part of the Visual Effects Assessment, three sequences need to be composited in Nuke . This is the first one:

The brief states that the footage needs to be stabilised when appropriate and viable, so the footage needs to be broken down into sections using multiple trackers. It also states that colour correction must be used to enhance the individual shots. It is important to note that brief is not asking to create any visual effects elements, this part of the assessment is about preparing the footage to move onto the effects stage.

The footage is broken down into shots, each one with its own individual brief. Here is a break down of each shot and what needs to be done:

Shot One (Frames 001-061)
Create hold out matte around the lamp and dragons in the foreground.
Shot Two (Frames 062-104)
Create hold out matte for girl staring into sky.
Shot Three (Frames 105-175)
Review footage, using judgement to determine if any work is needed or viable.
Shot Four Frames (176-214)
Create hold out mattes for the children, lamps and dragons against the Bluescreen and mattes for the children against the lamps and dragons.
Shot Five (Frames 215-237)
Review footage, using judgement to determine of any work is needed or viable.
Shot Six (Frames 238-272)
Create hold out mattes for the children, lamps and dragons against the Bluescreen and mattes for the children against the lamps and dragons.
Shot Seven (Frames 273-323)
Review footage, using judgement to determine if any work is needed or viable.
Shot Eight (Frames 324-354)
Create hold out mattes for the children, lamps and dragons against the Bluescreen and mattes for the children against the lamps and dragons.
Shot Nine (Frames 355-449)
Create hold out matte around the ornate lamp and dragons in the foreground.

First Thoughts:
The footage is quite shaky, most of it will need stabilised, there isn't anything in the scene that looks like stabilising will ruin the shot. The best objects in the footage to use as reference when stabilising are the the corners of the lamp and the square black cloth in the Bluescreen shots which is there as reference for the actors. Those objects won't be moving and they stand out well. The main concern is what to do with the rotos I have creates for one shot, for example shot one, and then it switches to a Bluescreen shot like shot four for example. What do I do with the rotas that are already in place? Is there a way to hide them for a specific amount of frames?
