After having finished the first batch and have had to work on other projects, I received an email about the upcoming batches which they want stored in a digital form. This digital copy will from then on be the "new original" and since this is for a national library, the final material ought to have as much detail/information left as possible.
What format would be most suitable to capture and store the material in?
The Matrox RT.X2 SD can capture in the following formats:
- Matrox MPEG-2-I-frame 4:2:2
- Matrox DV/DVCAM
- Matrox DVCPRO
There are only settings available to change when capturing to MPEG. I can then set the data-rate (25Mb/sec max), rounding type (MPEG2 or Matrox custom), zig-zag order (regular or alternate), DC-precision (8-11 bit) and finally I can force frame-based DCT.
Audio-wise I capture to wav (16-bit/48KHz, unable to capture 24-bit).
So, what format would be the best alternative for capturing and then long time storing of the material?
We are still dealing with VHS material and older.
