1. INTEGRALITY OF THE TECHNICAL INTERVENTION

The technical intervention (preservation and conservation) of these types of archives demands the use of spaces that meet humidity, temperature, and fire protection standards, as well as technology and specialized human resources, which allow guaranteeing processes that comply with international standards in terms of digital preservation.

Phases of the Intervention

PHASE I – RECEPTION.

The technical intervention requires adequate environmental and asepsis conditions, in addition to the use of human, technical and technological resources that guarantee good quality in the digital files resulting from the digitization process.

This phase includes the execution of technical processes for receiving materials, inventory and external cleaning, processes that will be executed on all the audiovisual supports to be intervened. If necessary, it would also include the transfer of audiovisual supports to Bogotá D.C. (Colombia)

1)    Reception of materials.
2)    Inventory.
3)    Packaging and shipping.
4)    Storage with technical supervision.
5)    External Cleaning.

PHASE II – INTERNAL CLEANING.

This phase includes the digitization of the prioritized audiovisual supports that will make it possible to have information in high-quality digital formats, of the contents of the supports available for intervention.

1)    Internal cleaning (cleaning of audiovisual tapes).
Deliverables: For the internal cleaning process, a database will be delivered that accounts for the results of the process.

2)    Digitization with Automated Control.  For the analog video digitization process, two copies of the digitized materials will be delivered, which will contain the high-resolution versions for conservation purposes (ProRes 422HQ) and the low-resolution versions for consultation and cataloging purposes (H264). These materials will be delivered on LTO-8 tapes. Likewise, a hard drive will be delivered that will contain the low quality versions, which will facilitate access for consultation and a database that will relate the technical issues found during the process.

PHASE III – BASIC AND ADVANCED CATALOGING AND RESTORATION. 

Cataloging: A description of the content of each of the audiovisual documents is made. It involves the description, among others, of the production context, content attributes and physical characteristics of each unit:
The cataloging addresses the following principles:

1.    Content recovery from the creation of metadata
2.    Database interoperability
3.    Historical assessment of the material

a)    Basic cataloging.
b)    Advanced cataloging.

Selection of elements for physical restoration. In conjunction with representatives of the Television System duly authorized for this purpose, prioritization will be established for the restoration of audiovisual supports with reproducibility difficulties detected in the previous phases. In this activity, different parameters will be considered such as formats, the state of conservation of the supports, the production date, and the historical importance of the materials, among others.
