We digitize and transfer older, endangered analog audio, video, film, and data formats and ‘born-’ digital audio/video formats. George Blood LP is often asked to help develop specifications for preservation and long-term access.
The process of preservation digitization breaks into two parts:
1. Digitizing, re-purposing, or migration of the original media.
Our engineers monitor the transfer of your source media, through a software interface, into a digital format. Whether the transfer is being performed as a 100%-Monitored process, (with one engineer monitoring each item from start to finish) or is accomplished by a Semi-Monitored process (an engineer monitors two or more transfers concurrently), we guarantee the quality of the captured content to be the same with either methodology. The criteria for recommending one of the two methods is dictated typically by the type of object, or content, and the condition of the source media.
2. Format and Output of the “Archival Set” to the delivery media.
Here is an example of the digital output that we create from your original content.
A typical “Archival Set” consisting of three parts:
- Preservation Master: a very high-resolution digital file
audio: 96kHz/24bit resolution, in WAV or BWAV format
video: Uncompressed, JPEG2000, or a format you specify
film: SD, HD, or 2K
- Access Copy: on physical media
audio: CD Audio
moving image: DVD-Video
- Web-accessible: “lossy” compression
audio: MP3, MP4/AAC, etc.
moving image: H.264, QuickTime, etc.
Delivery via: Hard drive, Data tape, or Web (FTP, Box, Dropbox, etc.)
