Achieving Maximum Performance
In Composition Builder, there are almost no limitations limitations regarding the number of layers, elements, and animations which that can be incorporated in a single composition. Nevertheless, the data acquisition and rendering of graphic templates is always done in real-timerealtime.

While developing graphic templates, we recommend to test testing them performance-wise in just:live or just:play on a regular basis regularly. |
If there are too many layers with complex animations/elements it is a good idea to reduce the complexity and split the graphic template onto to multiple Just Out engines. Only this can assure the best on-air performance and a good engine buffer status. For information about using multiple Just Out engines and the buffer status, please refer to the just:play/just:live user manuals.
We also recommend to use using still images (single or part of an image sequence) with the minimum pixel size possible and to position positioning them later in Composition Builder. Transparent pixels which are part of a still image have to be rendered, which can cost a substantial amount of power. Using fewer pixels can improve the render speed dramatically.

With version 4.0 of Composition Builder, relative paths for XML, movie movies, and images are now supported. Additionally, there is a new "“Make Paths Relative" ” item in the "“File" ” menu that will automatically find and replace absolute paths with relative paths, assuming the file and the composition are both located on the same volume.
Also there There is a new "“Embed Resources" ” item to available in the "“File" ” menu. This will automatically locate any XML, movie, and image files referenced within the composition, copy them into the composition file, and make the file paths relative to the composition file. This can obviously lead to much large larger composition files, but makes copying much easier as only the composition file needs to be copied and not the associated resources.
Legacy Composition Optimization
In the "“File" ” menu, there is a new "“Upgrade Components" ” item. This performs additional optimisation optimisations on the underlying compositions saved by Composition Builder and played out in either just:live or just:play.
