Our Library Migration Methods

Reporting and Monitoring

Reporting and monitoring considerations are always important parts of any library migration workflows we create for our clients. These processes provide valuable information about the actual quality of each asset, and let you know useful updates on the status of your content, and progress in general.


ISR is a really useful status reporting system that Sony built into its VTRs to help users track and categorise any channel condition errors that the machine identifies. It gives you a traffic light status of Red, Amber, Green based on the quality of the signal and the presence of errors that the machine is able to detect on the tape. These errors are caused by the DCT (discrete cosine transform) codec breaking down due to a loss of RF – the signal read from the magnetic tape material. Sony used this SNMP protocol to wrap the reporting into a machine-readable signal. At LMH, we have designed our orchestration system so that each VTR in each of our Flexicart robots feed back automated data on the quality and condition of each tape. This can then be used to identify where remedial work is needed to produce a usable asset.


Keeping track of your progress when you are running out a large (sometimes in excess of 50,000 tapes!) library migration exercise can be a real challenge. We found the only way to reliably tackle this issue was to develop our own bespoke monitoring systems. There simply wasn’t an off-the-shelf solution that made the grade for the complexity of our workflows. Not only do these reports allow our production team to keep track of progress, they can also be shared with our clients so that you are always up to speed.


Pushed notifications are our main tool for keeping you informed about how your library migration project is progressing. These reports are pushed out to an email address of your choice once a week or once a month, depending on your needs. The report content itself is fully customisable but will usually include information such as a breakdown of the format of ingested assets, and a project status summary.

This is a really helpful tool which allows us to track the progress of an asset step-by-step through the workflow – from digitisation all the way through to upload to the client and beyond into Exception reporting. Exception is used to describe an asset that has not met the basic quality set out for each particular project (the quality threshold is something we define with you at the outset of the project, and will depend on the usage criteria we decide on for your migration). Every asset is measured against this threshold for compliance. Where the asset quality falls short, we can review the Exceptions and attempt to remedy the problem.

Metadata intelligence is a really useful part of the reporting process. It provides information which can be assessed, such as the average run times of each collection, as well as the overall run time. This data can be useful for billing and feedback to you, the library owner, so you can update your own metadata database.
