Etere Ingest through its Operations By Workflow module, allows to check the file length of video file(s) stored on specific metadevice(s) and associated to certain assets that have been linked to a proper Length Check Workflow (i.e. a T-workflow which contains a Asset File Length action), that action will detect any discrepancy (of one or more frames) between the logical and real duration of assets, and if it exists, the logical duration will be updated with the real one (including SOM and EOM timecodes).
This feature is useful to, for example, update the duration of asset forms that have been created with a referential duration with the duration of the video files that have been linked to them. The image below illustrates how the 'Duration' (logical length) of a certain group of asset forms has been updated with the real one (physical duration) after a 'File Length Check' T-workflow execution:

In order to perform this kind of operations, please refer to the proper chapter regarding the Operations By Workflow module.
