Pro-Res conversion archival for Hi8 tapes?
Hi Lordsmurf, in your opinion Pro-res HQ digital copies of PAL Hi8 tapes played with a Sony EV-s9000 and converted to Pro-Res HQ files with a AJA io HD ,can be considered as archival copies? Thanks

ProRes is a video codec with lossy video compression. You need a lossless video codec such as HuffYUV or Lagarith for archival master copies of your analog captures. |

So, the answer is: YES, maybe. :hmm: It really depends on the source. Samples needed, attach a tiny clip (fleeting seconds, less than 00mb total) to a thread. Quote:
I keep a lot of master copies as high bitrate MPEG, both 4:2:0 (a compromise) and 4:2:2 (not always compatible with home viewing, but computer fine). Note that the MPEG also has low GOP, not long GOP. Sony, for example, considers some MPEG to be good enough for an intermediary, not just delivery. It's a wide format, many options. Quote:
Noise is the enemy of all compression. "Archives" should mean that editing is done, restoration is done, it's simply being stored now. Unfortunately, "archiving" has multiple definitions, but most should agree it's done after a project has been completed. The idea that you'll redo it in the future is actually a fairly recent phenomena, so "archiving" is often overkill -- especially when the source has been given the best treatment possible (TBC, color correction, max SD resolution). When I think future methods may improve something, only then will I saw the large lossless file. |
