Blocky images when handheld

Wow, guys get would up fast around these parts :-)

Lots of my stuff ends up being hand held. I shoot lots of skating and bmx stuff inbetween and am pretty paranoid about such a sizey investment. Stuff in South Africa isn't cheap when you have a new government ruining our economy...
 
The only negative things I've seen from this cam were a helicopter shot where the whole image turned to jello, and images flickering from florescent lighting. But those were rolling shutter issues, not codec issues.
 
images flickering from fluorescent lighting arent rolling shutter issues. You adjust the shutter rate or use the flicker reduce function. I only have it when shooting 60fps in the UK when I should be shooting 50fps under artificial lighting
 
Crank up the shutter speed and you'll see it for sure. If you're under fresh, properly-working lighting you shouldn't see it when using 1/60th (in NTSC), but if the ballast is flickering or if you're using an off-sync shutter you'll see rolling bands.

Look at the last example in this article; that's 24p @ 1/48th but shot under a flickering fluorescent.
 
It sort of looks like a bit of a rolling shutter issue at the start of your short "My Autumn's Done Come" only in the bathroom shots though. But maybe it's something else. I was not looking for rolling shutter issues. Simply checking out more of your fantastic work and it seemed to stand out simply in that one spot.

It does look like dark line flickering as Barry says. The strange thing is that I do not notice it at all on your dad's(I assume) face while brushing his teeth or when shaving. Yet the dark flickering lines pop up on the edges of the frame. Maybe because there's a constant stream of natural light on his face?

It's nowhere near as bad as the examples from the article; however, in the closeup of toothpaste I think is probably the most evident area of dark flickering lines.

Having said that I think it's possibly only an issue, because it's slow-mo and fairly static in terms of what is happening within the shots? During a normal scene with a modicum of movement to distract the eye I don't really think that flickering would be as noticeable? Sort of like in your KGB Theme park interior shots, where there is running(wearing gas masks) and a lot of camera movement. I doubt anyone would be able to notice if there is issues with the fluorescent lights, especially if they are not looking for it.
 
that was not rolling shutter that was 60fps in a 50hz country. The lights caused it. I learned my lesson from that!

Am shooting loads of handheld in LA at the moment at night with ambient light, whips, crashes etc no problems all the footage looks great, even with 9db of gain in
 
ah ok. I was wondering if that was the issue, but wasn't entirely sure since it was fairly pronounced sin spots, but that's why it pays to ask questions to clear something like that up.

9db gain is pretty impressive. I know you added magic bullet to the KGB Theme Park Piece, so obviously the shadows are much more pronounced. I'd be intrigued to see some of the uncorrected footage from that, since even with grading the exposure under such minimal lighting is impressive(That and I love heavy shadows). Did you use any gain, or were you shooting at 0db during the initial shoot for those tunnel shots?
 
After much reading on the net, does anybody have footage of an orchestra being chased through a forrest by some cops with their lights flashing, on snow with their nd on?

I almost had that yesterday but it was a horde of ukulele players being chased through a coconut grove. So you can't really tell if there were any artifacts. All the coconut trees tend to lean anyhow.
 
Phil, have Sony started paying you some dividends yet? You must have sold more of these cameras than their own marketing campaign! :laugh: Beautiful stuff as always.
 
Stoked!!! That footage is amazing, how did you get that guy to jump throuigh that fence with the chelo??? And was that live amunition? ;-)

I've got the option of going to test the camera next to an hvx withb flashing lights/different shutter speeds shooting stuff more similar to what i might use it for...

will try post some footage if i go...

Unfortunately it doesn't snow here, but i'm sure i can find an orchestra and some cops...
 
it's easier to find a string quartet than an orchestra. I got lucky. I bumped into a 30 piece orchestra whilst queuing for taco bell and they had all their instruments and were up for it.
