ProRes Everywhere, and End-to-End Color Management

SynthEyes 2204 now offers Apple ProRes codec support in Windows and Linux; previously it was available only in macOS. The tutorial runs through features of the ProRes support, including how to write ProRes files with colorimetry matching the original. A new feature uses presets to ensure Save Sequence always writes with the correct colors.

How and Why to Unsolve a Scene!

Under some situations, you need to UNsolve parts of a scene: when a solve goes wrong; or when the solver detects an error and says you must, after you've deleted too many trackers. A new graph editor channel, #Solved, shows the number of solved trackers on each frame, providing guidance and insight into the solver's operation.

RED GPU-Based File Reading

Runs through some details of GPU- and software-based reading of RED Movie files in SynthEyes. If your GPU is suitable, it can provide 10x faster reading than software-based reading (which is limited to single-threading by the RED SDK). The best way to find out if your GPU is suitable is to try it! NOTE: GPU-based file reading was introduced in SynthEyes 1511.

Using Google Maps as a Reference Mesh

You can use a 3D mesh as a reference for a camera-only match-move, for example to add a new building to an exact location in an existing environment. Here we use a flat plane textured with images from Google Maps as a reference (in lieu of a site plan).

Using the Green-Screen Panel

This Quicktime movie shows SynthEyes's green-screen system at work. It allows SynthEyes to track only the green screen, and ignore features on the actors moving in front of the screen, so that they don't have to be masked out from tracking. Shows typical issues and solutions handling these shots.

Using Hold Mode

The hold-mode feature of SynthEyes 2008 enables you to match-move shots where the camera translates during part of the shot, but also only rotates during part of the shot. In essence, these shots contain both a regular section and a tripod-mode section. With the hold-mode feature, you can easily solve complex combinations of these motions.

Franken-Tracking with Splice Paths

Sometimes you need to combine two separate tracks together exactly. Most commonly, this involves a shot consisting of normal sections and tripod sections, but other situations might include a shot with a major occlusion in the middle, or as a starting point for a shot that transitions from a wide shot to a full-frame moving object (still tricky). In the past, you needed to assemble the tracks in your favorite animation package, but it is quicker and easier to do it in SynthEyes. Largely but not always superceded by Hold Mode!

Building a Shadow Catcher

In order to have a correct shadow cast onto a live shot, a piece of proxy geometry is needed that approximates the 3-D scene in the area where the shadow is needed. The original imagery is projected onto it, and shadows cast onto that textured geometry.

Dynamic Projection Screen

Talks about the dynamic projection screen generator in SynthEyes's perspective view. The projection screen shows an undistorted version of the original footage and can show a keyed version of the original shot. It adapts immediately to changes in field of view and distortion.

Projection Screen Generator

The projection screen generator creates physical geometry in the scene to hold a background image, which can make some setup and scene-building tasks easier --- especially for green-screen shots. For green screen shots, SynthEyes can leave the keyed portion of the image transparent. This works for internally-keyed shots, or for shots with externally-generated alpha channels.

Different Frames in Different Shots

When you work with a longer main shot and a shorter reference shot, it can be convenient to scrub them independently to different frame numbers, to facilitate linking the trackers from shot to shot. This tutorial shows how to do that, using a camera + perspective view.

Creating a Moving from a Still

You can use the image preprocessor to create motion from stills, the "Ken Burns" effect. This tutorial shows a simple example of that. Doing it in SynthEyes is different than doing a 2D image zoom and pan, because, with the proper lens field of view, it is recalculating the correct perspective shift, as if the camera was on a tripod, instead of the 2-D image-being-slid-around look.
