When upgrading to 5.10, as many old media formats as possible are automatically migrated to new formats. In particular, a new format with the same name as the old format is created, and then the old format is mapped to the new format. This is only done for old media formats that can be mapped to a supported format type in the new transcode system. Please contact RnD R&D if you have a use case for a format type that is not supported in the new transcode system.
...
All changes to the old media format are ignored.
Renditions are no longer generated based on profiles. Thus, if renditions of the old media format were previously being generated when an asset was published to a specific channel folder, this is no longer the case. Pre-generation can be set up for the new format. However, please carefully consider if this is necessary now that the transcode system supports on-demand transcoding.
Existing renditions are not re-generated. Thus, the existing renditions will be used when requesting renditions of existing assets in the new format. This is also the case if generating the rendition with the new format definition would lead to a different rendition than the existing rendition. As described in https://digizuite.atlassian.net/wiki/spaces/DD/pages/3708157997/DC+5.10+Breaking+changes+-+Transcode+system#New-thumbnail-formats, it is possible to use the “Generate asset renditions” automation step to force existing renditions to be re-generated.
For new assets, the new transcode system and the new format is used to generate renditions. This is also the case if a rendition of the old media format is requested.
Renditions of the format can still be requested with the id of the old media format. This is mainly relevant for backward-compatibility reasons.
...
All new formats that have been created as part of the automatic format migration, described above, will appear as delete actions when diffing in configuration management. Please ensure that these formats are exported into a custom layer before applying the configuration.
Revisit formats
Although not strictly necessary, the introduction of the new transcode system provides a good basis for revisiting the formats that are defined for existing customers. Maybe some of the old media formats are no longer needed. Maybe some of the automatically mapped formats can be mapped better manually, for instance utilizing the support for webp and transparency.
When revisiting the available formats, please keep an eye out for the following:
Are there any used media formats that have not been manually mapped to a new format?
This can happen if the new transcode system does not support the type of the media format. If you encounter such a case, consider if one of the supported format types in the new transcode system can be used instead. Otherwise, reach out to R&D to share your use case.
