If a shoot needs tracking markers, what shape, size, colour, count and placement do practitioners and tool manuals recommend, and where do they disagree?

Two practitioner accounts (2016) agree markers are a fallback and should be small, simple and at different depths, but disagree on numbers: one says at least nine dots visible at any moment, the other at least seven. Marker size is given only relatively (just visible in the widest shot) plus one anecdotal tape size (half-inch squares). The tool manuals read (Nuke, Blender, SynthEyes) describe what the software needs from features (non-coplanar, high contrast, not reflections, mask movers) but state no physical marker size, spacing or count. Curator qualifications: All excerpts located; practitioner disagreements (at least nine vs seven dots; crosses vs dots) kept as genuine practice differences. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
