Originals
The one file you can’t export twice
This spring, Isabel’s partner, an industry association, asked for the original recording of a 4K seminar: they wanted to re-cut it for their trade show. Isabel opened the video in SproutVideo and found only transcoded versions. SproutVideo’s help center is upfront about this: in its example, the highest-quality file available is “the 1080p version.” The original is kept only if “Keep my original source video” is turned on in the account settings, and only for videos uploaded after that. Isabel’s setting was off. And if you turn it off later, the help center warns: “all your previously saved source video files will be permanently deleted.”
“No problem, the editor has the master,” Isabel decided. The master sat on the editor’s SSD. And here’s something few people think about until it happens to them.
In a 2016 study, Bianca Schroeder of the University of Toronto and Google engineers Raghav Lagisetty and Arif Merchant analyzed six years of SSD use in Google’s data centers—ten models, millions of drive days. Depending on the model, 20–63% of drives hit at least one uncorrectable read error. Those were data-center drives, watched over by engineers. An editor’s laptop lives a much rougher life.
Hard drives are no better. In 2007, Lakshmi Bairavasundaram of the University of Wisconsin–Madison and his colleagues at NetApp tracked 1.53 million drives over 32 months: 3.45% developed latent sector errors. “Latent” means the drive still works, but the sector holding your file can no longer be read, and you find out only when you open the file. Usually on the day you need it most.
A drive’s datasheet isn’t a guarantee either. In 2007, Bianca Schroeder and Garth Gibson of Carnegie Mellon University compared manufacturers’ promises with reality across about 100,000 drives: datasheets put annual failures at no more than 0.88%, but in practice 2–4% of drives were typically replaced each year, and in some systems up to 13%. And in 2008, Weihang Jiang and his colleagues from the University of Illinois at Urbana-Champaign and NetApp showed that disks themselves cause only 20–55% of storage subsystem failures. The rest breaks around them.
Isabel’s master was eventually found—on a third copy, after two days of searching. She got lucky.
With VodSpot, this story doesn’t happen. The original is always kept, with no setting to remember and no “too late to turn it on”: we never re-encode it, and we keep it separate from the streaming copies. On the delivery page, the client or partner clicks “Download” and gets the exact file with its original name. It’s your second copy, and it doesn’t live on someone’s laptop—the main reason teams choose a SproutVideo alternative that keeps originals by default. We covered why a cloud folder does worse at this in video hosting vs. cloud storage.
You can make another encode any day. You only get one original.
