CC wire removal is pretty easy to use — it stitches the scene together from the right and left of the line that you create by placing the two points.
You can experiment with the thickness…
In looking at your film it looks like you mostly have that one bad scratch…
You won’t need to break the film into sub-clips because you can apply more than one instance of the wire removal effect to the same shot… — in fact, if the scratch is very thick, instead of cranking up the “thickness” (which will create a smearing/tearing effects) , try adding two or more instances of CC Wire Simple Removal and attacking the line in two (or more pieces)…
Remember, you’ll want to key frame the two points to keep the points centered to your line– I doubt motion tracking would be very helpful in your particular circumstance… When the line disappears for a while, you can move the A&B points out of your frame; make a HOLD keyframe and just keep the points there until you need to bring them back on to your frame.
One more suggestion, sometimes if the bottom half of the frame is dark and the top is bright (or if the thickness of the line is thicker on the top and thinner on the bottom of the frame) , you might want to handle the top half of the frame with one application of WIRE REMOVAL and the bottom half with a second instance of the effect — that way you can dial in a different “thickness” for the top and bottom… In this example the “A” point might be at the top of the frame and the “B” point might be somewhere near the middle of the frame” — and in the second instance of the WIRE REMOVAL the “A” point would be near the middle of the frame and the “B” point would be at the bottom of the frame…
