Is it possible to not use tracking markers?
If you take a look at his demo reel above, you’ll notice there’s an absence of tracking markers in any of the shots. Matt Merkovich uses SynthEyes for most of his 3D camera tracking work, and he has an outstanding series on his Vimeo channel that shows you how to use it to track marker-less, otherwise impossible-to-track shots.
When to remove tracking markers from a scene?
Tracking Marker Guidelines from MattMerk on Vimeo. In the pre-production phase, keep in mind that while tracking markers aren’t that difficult to remove, you are in fact introducing extra elements into the scene that will require additional time for removal. It’s a good idea to consider:
Can You crop tracking markers out of video?
You also may be able to easily crop out tracking markers on the periphery of your footage, by performing your track, then simply scaling up the video! That method would provide you with the safety of ample tracking data, with pretty much zero effort in post. Let’s say you decided you do need tracking markers.
Do you need tracking markers to track hair?
The greatest irony in compositing is having to track hair patches to an actor’s head (with NO tracking markers) just to reconstruct the hair that was destroyed by that stupid, giant, garish neon pink X somebody taped up there. • You typically need to see around nine dots on screen at any point to get a good track/match-move.
How many dots do you need for a good tracking move?
• You typically need to see around nine dots on screen at any point to get a good track/match-move. The dots can leave and re-enter frame during camera moves, but you still need to see about nine dots at any given time. That just means you need more dots off camera that come on when you pan and tilt.
Can a track marker be used in the same frame?
Selected tracks should not have common tracked or keyframed markers at the same frame. The Average Tracks operator creates a new tracking marker by averaging the data from the selected tracks. This can be used to improve stability of tracking on blurry or non-very-sharp feature shapes.
What happens when a marker is disabled in Blender?
If during sequence tracking the algorithm fails to track some markers, they will be disabled and tracking will continue for the rest of the markers. If the algorithm fails when tracking frame-by-frame, the marker is not disabled, and the most likely position of the feature on the next frame is used. Tracks the motion backward along the sequence.
