The Old Interlaced Man

Something disturbed me horribly at work today. A fairly empty shop this morning aside from a two nice customers and one... idiot.

Ignorance I can tolerate, but when someone believes information they acquired from "the guys down the pub" so blindly that when reality stares them in the face they righteously trot away like a religious fanatic being shooed from a front garden, that is stupidity, which I cannot tolerate. I quote:

"Good morning Sir, how might I help you?"

"I'm looking for a really good camcorder, where is that camcorder shop on Byres road?"

"It's actually just down on Great Western road, all the way to the end of Byres and turn right. Would you be interested in any Panasonic camcorders? How about the SD700?"

"I don't want any of this 1080p rubbish. I want 1080i."

"Why's that Sir?"

"Allow me to enlighten you. The 'i' stands for interlaced, and the 'p' for progressive. You can make a progressive picture from an interlaced one but you can't get an interlaced picture from a progressive one."

He begins to open the door to leave


"But Sir! This camera shoots 50p!"

He's gone


If this were a film (rather than real life) I would then state "FML" before continuing in my mopping of the floor.


So yeah. The SD700 shoots 1920x1080 @ 50 progressive frames a second. Hence you could lose every second frame to get 1080p25 (standard progressive). Or use even lines of first frame, odd of second and interlace those fields to get 1080i50 (standard interlaced).

But he obviously knows best since he's old.

That pissed me off, glad to get it off my shoulders... or back even... chest? insert expression here
