Matrix presentation curatecamp_04192013
- 1. Format Comparison for Analog-to-Digital Reformatting (The Matrix) April 19, 2013 CURATECamp AVPres
- 2. Progress Report • Small NARA working group – LOC Culpeper and AVPS, also contributing • Populating the data cells – more than halfway done (DRAFT) • Some structural changes • Received input from FADGI members at last AV meeting
- 3. Overall Structure • Across the top are the formats we’re evaluating • Down the side are the criteria we’re using for evaluation • Evaluating wrappers and encodings separately • Show Matrix
- 5. Overall Structure, cont. • Show Matrix • Section 1: Sustainability Factors (from LOC and Carl) • Section 2: Cost Factors (how much does it cost?) • Section 3: System Implementation Factors (how difficult is it to do?) • Section 4: Settings and Capabilities (what special or additional features does it support?)
- 7. Recent Changes • We’ve added MPEG-2 PS and TS to codecs – This raised some interesting questions about what exactly the encoding is doing vs. what the wrapper is doing, especially in terms of metadata support – We might still evaluate the ad hoc .mpg wrapper on the Wrappers Tab • Uncompressed 8 and 10-bit were split into 2 columns – They are distinct and have different strengths and weaknesses
- 8. Next Steps… • Will continue to populate data cells • Compile narrative – Planar vs. packed, MPEG-2 wrapper and encoding, second-tier Encodings, etc. • Watch this space: http://www.digitizationguidelines.gov/guideline s/File_format_compare.html
