And I thought you never blinked. :D

Well, it happens to me, too... usually, once or twice during a whole movie, so this was an unfortunate event... (^^,)

Tomorrow morning encoding will be finished; I'll mux it, watch it (with two toothpicks that will take my eyes wide shut during the whole film) with my wife (who will be applied the same technique, even against her will) to be sure no frame is bad encoded, and finally I hope to re-release it tomorrow afternoon... wish me luck, I'll need it (in particular with the toothpicks affaire)!
