The official Syntheyes Tutorial Area of their website has a number of good tutorials covering all aspects of the software. If you are new to the app, this should probably be your first port of call (click here to go there)

Matthew Merkovich has done a number of syntheyes tutorials.

He has been a match over for eons so to show the sorts of things he has worked in I’ll pop his Minority Report and Dr Doolittle demos below (which are an interesting behind th scenes anyway)

Now to the syntheyes stuff. First up a basic intro to syntheyes interface.

Rubiks Cube tracking

If you want to do head/face object tracking in syntheyes, have a look at the below series. The first ones cover a basic head track, his second series shows how to track ad forming face (to get a deforming mesh).

 Next is his head tracking series:

Tracking Face Deformations (soft tracking)

Here is another intro tutorial by Fenix Motion Graphics

Samuel Fuller also has done a two part intro tutorial 

Pixel bump also have a gory face track using syntheyes, realflow, maya and after effects

Another tip is if you’re using a decent Digi green or blue screen and you want markers you can quickly throw on the screen or move with little hassle, make up some markers using velcro (hooked side). On most modern screens the markers can write literally be thrown on the screen and will stick. Even handy if you have pre-marked the screen using coloured gaffer tape markers but they go for a close up and you see no markers are in shot. In this case you can quickly throw a couple of trackers into frame (faster than tape).

If you want to matchmove a shot you really want to have things at different depths for the software to use that parallax to work out the camera movement. You can either add green sticks (or c-stands) just out from the screen with markers on or make sure you have props with trackable textures. In that regard, work with the art Dept to make props, set pieces, that have some features that can be tracked built in (so the audience just sees a normal prop, the matchmove artist has decent textures to track in the set, & the comper doesn’t get angry having to paint out coloured dots on the set). Again, camera tests before the shoot will tell you what you need for your particular situation. 

Shapes of markers is a subject that’s debated. Crosses are favored by some as one cross can provide multiple points to track which can help in frames where you don’t have many markers in view. The down side is when they get out of focus their shape becomes a bit like a blobby  cloud which can change frame to frame and upset the tracker. Because of this, some match movers prefer round dots (of course that means you need to make sure you have at least 7 in shot at any one time, at different parallax distances for a matchmove (unless the set has trackable features). Heres an article and video about that.

For those not on the shoot but handed coloured markers on screens that need removing you can try having a look at this  (click here) Nukepedia written article for inspiration.
At the end of the day you’ll most likely have to endure some paint work if the above doesn’t work but creating a garbage matte so you only deal with stuff crossing close to the edge of your subject will limit this pain.

Here are a couple of videos HollywoodCamerawork did as an intro to matchmove marker placement (from their vfx course).

For more info on matchmoving in general I recommend this book:

* note that the image at the top of this article is also from HollywoodCameraworks site (click here). If you want free vfx plates to practice your keying or tracking check them out. Also their camera work course is awesome and I’ve found the vfx course good to help explain certain techniques to directors in the planning stages. 

This is a handy website for anyone who needs to do matchmoving or photogrammetry as it provides information on a huge range of cameras (including film back, sensor dimension, sensor imaging area and colorspace specifications). Click the below image to go to the site.
