I can get the active tracker like this:
bpy.data.movieclips.['clipname'].tracking.tracks.active
or
bpy.data.movieclips['clip_name'].tracking.tracks["track"].select_anchor = True
Is it possible to get its position?
Or set its position and then keyframe it?
From the docs:
template_marker(data, property, clip_user, track, compact=False)Item. A widget to control single marker settings.
[TABLE=“class: docutils field-list”]
[TR=“class: field-odd field”]
[TH=“class: field-name, bgcolor: #EEDDEE, align: left”]Parameters:[/TH]
[/TR]
[/TABLE]
This is what displays the widget in the panel with the heading: ‘Marker’
But how do you set these values from Python?
Looks like that thread is adding new markers… is that what you really wanted?
I’m just getting into some serious python so I treated this as a learning experience and spent a couple hours trying figure out how to move a selected marker at the current frame… (yeah, it took me that long… no worries, I picked up alot of useful info along the way :yes:)
anyway, just in case, here’s what I came up with:
import bpy
curframe = bpy.context.scene.frame_current
###################################################
# if you are making addon for the clip editor, #
# you can use top and comment out bottom #
###################################################
#clip = bpy.context.space_data.clip # will not work in text editor
clip = bpy.data.movieclips['P1010123.MP4'] # use your clip name here
###################################################
size = clip.size
marker =clip.tracking.tracks.active.markers
for m in marker:
if (m.frame == curframe):
break
print ("frame %d selected marker location x: %6.3f (pixel %6.3f)" % (curframe, m.co[0], m.co[0] * size[0]))
print ("frame %d selected marker location y: %6.3f (pixel %6.3f)" % (curframe, m.co[1], m.co[1] * size[1]))
moveto_x = 1050 # new x location in pixels
moveto_y = 700 # new y location in pixels
m.co.__setitem__(0, moveto_x / size[0])
m.co.__setitem__(1, moveto_y / size[1])
print ("frame %d selected marker new location x: %6.3f (pixel %6.3f)" % (curframe, m.co[0], m.co[0] * size[0]))
print ("frame %d selected marker new location y: %6.3f (pixel %6.3f)" % (curframe, m.co[1], m.co[1] * size[1]))
