Raising more questions than answers, Professor Ken Kobre (via @NiemanLab)wonders about correcting errors in online videos:
However, what happens when there's an error in an online video story? Not as simple to fix! Depending on the nature of the gaffe, you probably have to yank it offline, and then… what? Excise the offending footage? Add explanatory chyron titles? Re-shoot new scenes or interviews? No matter what, re-editing a video is a lot more time-consuming and labor-intensive than re-editing a text story. Or should you just add a text correction next to the video? (But then what if that video is "shared" on Facebook, or embedded on another Website? The text Band-Aid won't accompany the flawed video.)
. . .
In short, given the enormous number of ways in which errors can creep into a video story, frankly we're amazed that, even after viewing thousands of non-fiction videos, we've never encountered a "video correction." Is it because they're all so perfect? Or because it's too much work to fix relatively minor errors, so they're just left in? Or because it's too much work to fix errors, and so the wayward video is just removed from the Website altogether? Or because the videos are fixed, and it's just not formally called to anybody's attention?
