Attached are two frame grabs from a 10-second shot recorded in 1080i on a little Panasonic SD5 AVCHD camera - replete (an understatement!) with motion blur artefacts. The second jpeg was grabbed after deinterlacing this single shot with iMovie HD. It tidies up the weirdness a little, but the shot is clearly still unacceptable. Is this an AVCHD issue (I know it's not an ideal shot in many ways, but I wouldn't have expected this much in the way of "blur") or operator error? TBH I can't now remember what shutter speed I was using, but it was a reasonably sunny day, and I think it would have been 1/100 or 1/125 at least. Your thoughts welcome. Thanks, Andrew. EDIT: I should add that the original .mts file was converted with Voltaic, preserving framerate and size, on an iBook G4. Naturally, it played back fine in the camera's LCD. It's not a one-off: I have a number of shots that resemble this, shot in a wide variety of circumstances, all converted with Voltaic and all unusable. The jpegs below are screen grabs from an LCD which I presume is progressive. But the deinterlaced shot is still rubbish.
