Getting rid off motion tracking markers
Hi,
Thanks for your time…
I have shot a music video – one of the shots is a girl on a white background.
So that I could use my recently aquirred motion tracking skills, I decided to stick black cross heirs on the wall when I was shooting!… this is great for motion tracking however!…
I realise that my graphics wont always cover up these cross heirs so I am wondering what is the best way to get rid of these black stickers (cross heirs) that I put on the wall???
I have tried single frame by frame rubbing it out but it does mean that it creates a flickering blob because sometimes it hasnt been just pure white.
Is there a way to clone frame by frame?… I seem to be able to clone but not frame by frame?… how would I get this smooth please?
cheers

I never do frame-by-frame painting (so far, anyway) for the reason you’ve mentioned.
You’ve done the tracking, so apply that tracking data to solids that are the same color as your background, so they can cover the tracking markers. Maybe draw masks on them to shrink them to the size of your crosshairs. Apply whatever animated effects you need (fill? curves? levels? ramp?) to make them match your background.
You can also apply the tracking data to a copy of the footage, mask it to cover the tracking markers, then use the pan behind tool to move the footage (slightly) behind the mask. This should replace the tracking marker with the area of footage right next to the tracking marker. Sometimes this works, sometimes it doesn’t. Sometimes it works for a few frames, then you need to reposition the BG footage, covering the marker with a new part of the footage.
Does that make sense?
