Depending on the chosen format type, a number of different parameters will appear. Most parameters should be self-explanatory. However, a short description of some of the key features can be found here.
Generation
Renditions of assets can be either be generated on-demand, or they can be pre-generated.
If a rendition of an asset is requested but has not been generated yet, it is always automatically generated. This feature referred to as on-demand transcoding and makes it possible to ensure that renditions are only generated when needed. Thus, storage space is not wasted on saving renditions that are never used.
...
Note that renditions of a specific format can not be generated for all input file types. For instance, renditions of video or audio formats can not be generated for image assets such as png
, jpeg
, and webp
since it does not make sense to create a video or an audio file from an image. However, renditions of image formats can be generated for most common input file types. Thus, even though a limited set of output formats are available, a wide range of input formats are supported.
Format visibility
One use-case for defining a format is to make it easy for users to download renditions of assets in this format. However, by default, a format is not visible in the download dialog in the Media Manager. The visibility of formats in the download dialog can be controlled from the general settings page in the Media Manager, where it can be configured for individual user groups.
