<html><body style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; ">There is a *huge* difference between the amount of storage needed in production/post-production and what ends up in the final master for delivery to theaters. Any movie will generate a ton of assets that don't make it into the final cut (although increasingly they do show up in DVDs post-release). <div><br></div><div>For 4K resolution digital cinema using a 4:4:4 colorspace and 36-bits/pixel of color information (pretty standard for the serious movie folks), a single frame takes 39.81 MB. At the standard 24 frame/second "film" speed, one minute of video imagery takes 28.67 GB. An hour will take about 1.72 TB; two hours 3.44 TB. Add in audio information, then compress the whole lot and you've got about 2TB of delivered film.</div><div><br></div><div>I seem to remember that the effects people who worked on Spiderman III typically had about 50 TB of assets online that they were having to manage for rending scenes. So, yes, the ratio of production/post-production storage needs and projection house storage needs are vastly different. One of the big questions for the movie preservation folks at this point is the question of whether archiving the final product is enough, or whether they want to archive *all* the raw assets, along with the edit decision lists that determined the composition of the final film.</div><div><br><div><div>On Jul 29, 2009, at 2:12 PM, Andrew Armstrong wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"> <div bgcolor="#ffffff" text="#000000"> Fair enough.

They can afford to pay a lot per byte, and their documents are small by comparison to high-resolution moving image collections; so there is an issue of scale. <br> <br> Henry<br> <br> Andrew Armstrong wrote: <blockquote cite="mid:4A709198.80902@aarmstrong.org" type="cite"> Really? fair enough, they need the quality of massive files.<br> <br> I'd love to see a breakdown of it, although it's barely something that related to the videogame world since even cutscenes are no where near the space of the digital-print quality needed as Jerome mentioned, and even if they were they are a few minutes in length.

I have seen a report by the archivist of AMAS (from about two years ago), which put the cost of industrial-strength management of current-gen digital-film masters in the seven figures range -- for one title! I think he was using the example of the most recent Spiderman film, which generated a digital master that was something like 2 TB in size. The bit-depth of theater-quality film, plus various tracks of audio and other information, results in a huge bitstream. His point was that studios are likely only to bear these costs while films make money, so there is real danger of loss. <br> <br> Comparatively, storing a canister of film is cheap. Even archives of nitrate masters (and I have been to a couple) in what are essentially concrete warehouses seem inexpensive by comparison, at least on a per-title basis.<br> <br> Henry<br> <div class="moz-signature">-- <br> <div><font face="Georgia">Henry Lowood, Ph.D.</font></div> <div><font face="Georgia">Curator for History of Science & Technology Collections;</font></div> <div><font face="Georgia"> Film & Media Collections</font></div> <div><font face="Georgia">HRG, Green Library, 557 Escondido Mall</font></div> <div><font face="Georgia">Stanford University Libraries</font></div> <div><font face="Georgia">Stanford CA 94305-6004</font></div> <div><font face="Georgia">650-723-4602; <a moz-do-not-send="true" class="moz-txt-link-abbreviated" href="mailto:lowood@stanford.edu">lowood@stanford.edu</a>; <a moz-do-not-send="true" href="http://www.stanford.edu/%7Elowood" eudora="AUTOURL">http://www.stanford.edu/~lowood</a></font> </div> </div> <pre wrap=""><hr size="4" width="90%">
