Mesh Match-Moving Tutorial
This flash movie demonstrates how to match-move a mesh, so that the mesh exactly matches its motion in the shot. Commonly used for head tracking from a single camera, it is applicable for any kind of moving-object shot where you have an existing mesh for the object being tracked. Best of all, this technique works even when the object moves little.
Once you've watched the tutorial, you may want to try it out yourself, or take a look at the final file. See fridge.zip (approx 10 MB) for the source image sequence and final SynthEyes scene file boxmatch3.sni (same zip file as for the tripod-camera + object-mode tutorial). You can download the QuickTime version of the tutorial (22 MB).
If you're new to SynthEyes, you can use the SynthEyes demo edition.
Notes:
- The video is 9:16 and 16 MB long. Check out all the other tutorials and the manual too (after downloading the demo version).
- Supervised tracking is typical for these types of shots, to create trackers that have easy-to-find exactly-matching points on the mesh.
- Note that you can do supervised tracking in either direction; for this kind of shot it can be easier to go from the end of the shot towards the beginning, and some of the trackers were done that way, or from the middle out.
- The HDV source footage was shot on a Canon XH-A1 in 30f mode -- 30 fps pseudo-progressive. It's then been recoded into an intermediate format, and then to medium-quality JPEG stills. Shot using a Spiderbrace.
- Mac version is the same, done on a PC due to capture software availability.
