  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

Hello,

our Viewfinder arrived today and shooting with it all day long, it had the following Problem 2 times: Suddenly in the EVF you see in some Areas Green or Pink Noise, kind of like the False Color display but only in Areas with a specific Stop. Also not very helpful noise. HDSDI does not have it. RED LCD might have it too, but cant check since it doesnt work at all anymore since 3 days.

The only Solution to bring the EVF back to normal was unplugging the cable and plugging in Again.

Any Ideas ? Could it be Camera or EVF ?

Greetings

Alex
 
P+S Technik is supposedly working on an optical viewfinder option for their IMS solution for the RED One.

Maybe Sanjin can tell you more. He's been to Ottobrunn many times before.
 
I've had similar issues with flashing RGB colors in the darker parts of the image in the EVF occasionally. (this is not the "eye movement" issue that's been brought up before.) I can't get the problem to recur reliably, so I haven't been able to test out whether it's the cable as RED said it might be.
 
Yes it isnt related to Eye Movement, really.

It was also in dark parts of the picture.

We had a similare noise issue with the LCD some weeks ago but only once and so i thought it was just a hickup and was fine.

i will change the cable today and see if the error will be coming again

Unfortunately you are right it is difficult to reproduce this error by own means.

The Reason for this Noise could be:

1. cable not sitting correctly and through not having contact in one of the pins for a short period, and that screwing up the following decode of the Picture Stream into the EVF.

2. EVF gets too Hot and then produces a processing error.

I don't think it's #2, because we've had the same issue and normally it happens when we first turn the camera on, i.e. it's cold. My guess is it's the contacts, unplugging and plugging back in always fixes it.

Sorry, I should have said it has fixed it every time for us. I really hope it's not a sign of a bigger issue and that it's going to get worse.

We also can fix it every time with replugging the cable. Today i changed the cable and we are currently shooting and nervously waiting to see/ not to see the Error. :nerd:
 
Alex,
I had a crawling noise/ edge enhancement looking issue with my LCD after I opened it up to retighten the Lemo connector. Pink dots outlining the dark areas. I had to re-seat the small connector on the board inside and it was fine. I guess one pin was intermittent until I really pushed it in.
I suspect that if it looks the same as my issue, it's the cable or the connector on one side or the other.
Cheers,
Harry
 
uh, wouldnt really want to open the evf, that will be warranty loss wont it ?

but i could really guess now its a connector fault,

anyone from the RED techs have an Idea on this ?

My problem is substantially different. It's extremely bright strobing in red, green and blue throughout all the darker areas.
 
I have the same problem in the dark areas. Unplugging sometimes helps.
