When upgrading to 5.10, the new and improved transcode system is automatically used. The old transcode system can still be used in 5.10 but will be deprecated in later releases.
In relation to this, there are a few things to be aware of.
EXIF
In previous version of the old transcode system, it was possible to embed EXIF metadata in the generated renditions/transcodes. This is not supported in the new transcode system.
Search2
Search2 allows the tables media_transcode_proxy_destination and media_transcode_proxy to be referenced in both input and output, providing access to information about transcodes/renditions. Information about renditions generated with the new transcode system can not be accessed through these tables. If one of these tables is used in a search, it is recommended to start using the API or the SDK to retrieve information about transcodes instead. This can be done using the endpoint <api-url>/DigizuiteCore/LegacyService/api/assets/search or the IAssetSearchService in the SDK.
