Yes.
Historically, every matchmoving app uses it's own UI for tracking 2D features. Unfortunately, the UIs of these are all different and not very user-friendly. It happens that an app cannot solve a shot that another one will, but you usually have to redo your 2D tracks in each one of them.
Another problem with today's matchmoving apps is that they are vastly inefficient when doing 2D tracks. Almost all of them use OpenGL and want to load the whole frame into memory at once. When doing tracks of long shots at high resolutions (like 2K and HD), especially on 32bit platforms, the app usually cannot even cache the whole shot and tracking is very very slow.
Compositing apps, in contrast, are very efficient. Both Shake and Nuke offer very fast trackers because they have tiling image engines and can load only the search area for the tracker into memory and not a pixel more. When you use manual feature selection you can create many tracks quickly even without having fast IO. Flame is also very fast since it has virtually zero IO overhead thanks to it's fast storage. Compositing apps also allow for precise, local preprocessing of tracking features like boosting contrast, doing expensive (especially temporal) denoise, blurs and so on, while matchmoving apps offer only a single, global preprocessing step (like a LUT or a gamma curve adjustment) which is not adequate for all of the features being tracked.
So it's very natural to track in a modern compositing app that has selective image loading, and then export one single group of tracks into all of the matchmoving applications at once.
Since your 2D tracking data is now freely interchangeable you can load the same tracks into multiple 3D tracking applications and see which one gives you a better solve. Should all the 3D camera trackers fail, you can still take your tracks into the 2D compositing world to do the job.
Sometimes you need to offset your tracks in time, or resize them to a different pixel format. Very few apps allow you to convert your tracks in one step from format to format - like doing an unproportional scale on the tracks, or moving them a few pixels left and right. This comes at a high cost if the footage you are tracking came cropped or in a wrong aspect - the only way to solve the shot will be to retrack it from scratch.
To circumvent this, Tracksperanto allows you to apply transformations to the tracking data that you export - and you can apply multiple transformations if desired.
To run on your own computer, make sure you have Ruby installed. Versions from 2.1.0 and up are supported. For older versions, use Tracksperanto 3.x and below.
$ ruby -v
ruby 2.2.5p319 (2016-04-26 revision 54774) [x86_64-darwin15]
Then install tracksperanto. It will be downloaded and unpacked automatically for you by the RubyGems system:
$ sudo gem install tracksperanto
If you do not have administrator access on macOS you can follow the steps in this video to use the gem as a user.
Once these steps are complete you are going to have a tracksperanto binary in your $PATH, which you can use like this:
$ tracksperanto -w 1920 -h 1080 /Films/Blockbuster/Shots/001/script.shk
To see the supported options, run
$ tracksperanto --help | more
The converted files will be saved in the same directory as the source, if resulting converted files already exist they will be overwritten without warning.
For situations where you cannot install anything on your machine, or you run a shitty OS that cannot run Ruby decently, or you are in a locked-down environment, we offer a web-enabled version of Tracksperanto at the following URL:
https://tracksperanto.guerilla-di.org/
This is a web-app which is always in lock-step with the main Tracksperanto in terms of versions, features and bug fixes. As a matter of principle, we reserve the right to use anything you upload to the web version for fixing bugs in Tracksperanto. Note that we usually scrub all the studio-specific data (like script and footage paths) from the files before adding them to the repo.
If you want your own copy of the web application at your facility we can discuss that, but it's not free.
Tracksperanto has a number of features to scale, move, slip, distort and rename trackers. Consult the --help option to see what is available.
If you are interested in reusing Tracksperanto's code or adding modules to the software consult the short developer introduction
Information about the search area, reference area and offset is not passed along (outside of scope for the app and different trackers handle these differently, if at all). For some modules no residual will be passed along (3D tracking apps generally do not export residual with backprojected 3D features).
Tracksperanto is made avalable under the MIT license that is included in the package.
