Doing a rather simple video export today, and cancelled and restarted several times sure I'd cocked something up as it kept saying it was going to take 2.5 hours and kept going up as I tweaked settings.
Finally realised it was giving wall clock time as an ETA - 2:30pm, not 2 hours 30 from now.
Consider this a friendly, local pub. Make yourself at home, bring your friends, have a good time! Meet new people, have a laugh, enjoy the ambience, and the Oxford commas.
