Very intermittent.
Sometimes the image on my LCD will "ripple" from bottom to top. Like a wave of magnification.
Recorded image is fine.
Build 15.
Anyone else?
Cheers,

Had the same problem. Unfortunately we also ran into HMI flicker which looks the same on the monitor, but is recorded to footage. So, before assuming that the ripples aren't being recorded in the future - make sure there's no HMI present and always doublecheck the footage.
 
Same here, i guess it's something to do with lcd internal (?) resizing. Because if you zoom in on lcd (round button on the top), it stops
 
No HMI. Natural outdoor skylight.
Funny because it seems to coincide with build 15.

Curious. Is it the LCD or the HDMI out signal? Are people having similar problems with non-Red LCD's or displays?

The LCD uses a different out than the HDMI port so perhaps there is a problem with that signal, with that connector or with the cable. Any way to narrow it down?

To reiterate, i noticed that problem on very fast pans, or in detailed frames, where big part of a frame changes. And only in mode where all menus are visible. When you zoom in on lcd, to the state where you see no menus, it doesn't flicker. So i think it's something to do with internal signal resizing 720 signal to fit 500 or so lines.

Seems to me like purely software problem.
 
I have had the same, even today - it has been brought up in other posts, and I think that it has been stated that this is something related to the firmware, hopefuly it will be resolved in an upcoming version.

In my case I sometime have some flicker in the lower part of the LCD, and today in daylght I got the flicker on a larger part when adjusting the iris on the lens. It seems to me that it occurs more often when the camera is cold - but that may just be me.

Like with the above, when I use the 2x magnification or go to the larger screenmode (with less info), it usually goes away.

It hasn´t showed up on the HD-SDI output, and annoying as it may be, it doesn´t worry me as long as I operate, it is however not a nice thing to have when you have other DPs operating - asking "what is this".

As other have stated above, I too have no faults in the recorded image.
 
I saw it on the 720p output as well. Do they all use the same processor?
Seems likely it's a software bug. Build 13 was fine...
And the frame was indeed showing high detail; the background was filled with cherry blossoms.
But to reiterate my issue again; it's NOT a traditional flicker. Its a wave of magnification that scrolls up the screen. The image in that wave gets slightly larger, like it's scaling up. THen the wave passes and it's fine again.

this was a bug with 15 when we enabled multiple monitor outputs.. just an after-effect of scaling. You can get rid of it sometimes by unplugging the monitor and plugging it back in.

next build hopefully should have the fix.
 
Thanks for the clarification Jarred.
Not a big deal, like I said, it's VERY intermittent... as long as someone's on the case for the next build.
Cheers,
Harry
