| - | ====== Natron ====== | ||
| - | |||
| - | [[http://natron.inria.fr|Natron]] is a node-based compositor. | ||

| - | ===== Strengths [Weaknesses] ===== | ||
| - | </WRAP> | ||
| - | |||
| - | **Non-Destructive** | ||
| - | |||
| - | <WRAP indent> | ||
| - | Node-based compositing is popular because it allows for major image manipulation with no enforced chain of dependency. You can rotoscope and resize and re-colour an image, and then remove any of those nodes without affecting the effect of the others. It's a powerful system used in most professional FX packages like [[Blender]]. | ||

| - | |||
| - | **OpenFX** | ||
| - | |||
| - | <WRAP indent> | ||
| - | Natron benefits from several open technologies and open standards, not the least of which is [[http://openeffects.org|OpenFX]]. OpenFX-compliant effects, both open and closed-source, from several companies and open projects are compatible with Natron. | ||

| - | **Professional** | ||
| - | |||
| - | <WRAP indent> | ||
| - | Natron uses several professional, industry-standard technologies on its backend, including OpenColorIO and OpenCV. It fits right in to established industry pipelines. | ||

| - | ===== Weaknesses [Strengths] ===== | ||
| - | </WRAP> | ||
| - | |||
| - | **Not A Clone** | ||
| - | |||
| - | <WRAP indent> | ||
| - | The usual warning about open source projects not being discount versions of famous closed source applications applies. Natron is a dedicated compositing application that is very similar to closed source applications that do, basically, the same job, but it's not a carbon copy of them. Comp artists will be frustrated if they attempt to use Natron as a copy of other applications in the VFX field. | ||
| - | </WRAP> | ||
| - | |||
| - | **Young** | ||
| - | |||
| - | <WRAP indent> | ||
| - | Natron is a fairly young application yet. While it is in use at several active production houses, it has yet to prove itself as a long-term reliable solution. | ||
| - | </WRAP> | ||

| - | |||
| - | ===== Install ===== | ||
| - | |||
| - | To use Natron at its fullest potential, you should have [[opencolorio|OpenColorIO]] and OpenCV (both available from [[http://slackbuilds.org]] installed. These are not strictly necessary, so if you just looking at Natron, it will still launch, but for actual work you probably want these technologies installed and active. | ||
| - | |||
| - | To a budding or working comp artist, even Natron's install will be familiar. Download Natron and run the executable. It runs an install "wizard" prompting you for an install location and offering an automatic download of various optional components. | ||
| - | |||
| - | The install can happen in two different ways: | ||
| - | |||
| - | * Run the installer as a normal user and install to a location in your home directory (for instance, ''~/bin/natron'') | ||
| - | * Run the installer from a terminal using the ''kdesu'' command and install to a systemwide location, (such as ''/opt'') | ||
| - | |||
| - | |||
| - | ===== Usage ===== | ||
| - | |||
| - | Compositing is both a science and art, but the user mechanics of Natron don't take long to pick up. There are not many tutorials online on the subject, but there are plenty of online tutorials on similar products, and the information and demo assets are surprisingly compatible. | ||
| - | |||
| - | ==== Basic Compositing ==== | ||
| - | |||
| - | The term "composite" literally means "something made up of disparate parts". In the context of visual effects, this refers to anything from overlaying text on top of video to taking a 3d-modeled troll and placing it next to a campfire that was shot in the real world. Both tasks require at least taking two separate images, dropping garbage that is not needed in a frame, combining the two images, and integrating them. | ||
