Re: [Avid-L2] digitizing a career's worth of hi-lites for a square pixel world

 

de facto standard for archival is jpeg2000, you may want to look into that too.

Thanks everyone keep it coming. Agustin you're right that one is supposed to steer clear of proprietary formats for archiving but I was swayed by a report by a major university that decided to go with ProRes after studying the issue. They (like my colleague) had a history of working with ProRes / Apple and felt willing to make certain compromises for certain conveniences. 

It's worth noting that no one has said bypass saving in D-1.  I wonder if organizations outside of the video post world would say that only square pixel, progressive files should be generated and saved?

Since he has Dbeta, play all the betaSP tapes in it as it has a far superior TBC over the analog decks. Take SDI out of the digibeta and into the SDI capture of your computer. You should capture at uncompressed NTSC 64K wave audio 720x486. Trim the shots up in quicktime 7 and then run them through compressor and output as progressive ProRes 422. Don't bother with HQ but do make them progressive.  This will be a process of never going through any analog passes. Good Luck.

I'm not an archivist. 
What we did for archiving a clients Betasp and digibeta material was to record them on a KiPro in ProRes. My main point is I recommend a hardware recorder like a KiPro, which is one of many options.  No exporting required.

I'm hoping the subject-line gets your attention and accurately reflects a dilemma. This post is about archiving/digitizing NTSC legacy work/tapes.

I'm trying to balance competing concerns and issues to help a colleague do a fairly large archiving/digitizing project for a career's worth of work. He owns an Avid of recent vintage and a digiBeta deck.  Working in an Avid environment, one normally likes to capture native and lossless for posterity. My technically well-informed producer colleague believes that ProRes is more than satisfactory for his posterity needs.  In our case "native" means 601 color space, rectangular pixels, 720x486 dimensions and interlace right?

After a discussion with him we arrived with this interim plan I'm vetting with all of you… capture/create the above native file (his Avid has ProRes as a capture/compression flavor) - export that Quicktime and call it the digital "master" from which other files will be made.

At a minimum one would want to make from that a high quality mp4 that is square pixel, RGB color space, true 4x3 (720x540) and progressive to play on all computer and tablet screens for the foreseeable future. How does that sound?

If the colleague ever wants to edit these digitized legacy files, he would work from the native ProRes files and export to whatever the target format is.

Thanks in advance for any feedback.

Best,

Paul

p.s. The interim plan is to capture digiBeta tapes at (regular) ProRes and BetaSP at ProRes LT
