Tracking Test
Tracking Test 1 from Matt Frodsham on Vimeo.
This was my first ever attempt at using pfTrack with just the autotrack (which is generally all that is needed) but without the knowledge to refine the solve so the result is quite rough. The screen below shows the public domain footage posted on mograph.net of a NY subway in pfTrack with the tracking points and the positioned 3D camera in relation to these. This is then exported as keyframe data to Cinema 4D or After Effects (or any other compositing software...). The second shot is from after effects where I applied depth of field to the AE camera and an orange coloured omni light so the text sat somewhat realistically in the shot.
Compositing Test
Matchmoving/Compositing Test from Matt Frodsham on Vimeo.
First attempt tracking and compositing, went through some issues with 'shadow catching' and after discussions with a few people in the industry decided that the cleanest easiest to use method was to use compositing tags and render out the main passes without the shadow on the floor, and then render a second shadow pass with all the geometry turned off in the render so compositing in after effects was much easier as the shadow was on a seperate multiply layer.

E4 ESting: Floating Farm from Matt Frodsham on Vimeo.
This was done quickly over about a day in total, while not really competitively taking part in the contest it did give a context to put the skills I'd learned recently into use so I shot some handheld footage around the farm and river near my house and composited some 3D E4 logos flyng through it. Some of the shadows were drawn by hand with soft masks where the floor couldn't be determined properly for example the large field with the long grass pictured below (no shadow, shadow in video).
The shots below are within Cinema 4D, the footage is set as a background object, the camera is exported from pfTrack and the geometry is then positioned easily with the use of compositing tags exported from pfT also to show the position of elements within the shot. This allows easier estimation of geometry and depth.
