RAW went Purple and Weird - Camera Reset!

[Adam Howden]

Had a not so funny thing happen to me on a shoot this morning. Fortunately it was a pretty low budget green screen single shot thing so whilst the pressure was on I was able to contain the situation. Thank god I ran a record test and popped it into the laptop other wise I may not have seen the problem until much later!

So what happened? The RAW image went all magenta and purple, like BIG time! The LUT look was fine but the RAW was very very out of whack! I fiddled a little but quickly decided to do a camera reset and re-boot! Thank Christ this seemed to fix it! I was running off mains and thought maybe that was the issue so switched to V-locks. It then happened again and I had to do the same thing, which again reset it and it was fine! I quickly re-set all my settings and quickly checked the footage on the laptop and it was all good so off we went. I was able to keep pretty calm and pretty discreet about it all, however I don't think I would have been quite so calm on a bigger job had there been more at stake.

Having read a recent thread this morning prior to this shoot about camera temperature and the fan kicking in on a critical interview I was very aware of the camera's temperature, it was sitting around 47-52 degrees C through most of the day but at this stage we'd only had the camera on for maybe 10-20mins. I'm on firmware 3.0.6. All other settings were standard, ie I hadn't dialled in any Look settings or anything like that.

Weird! A little frightening and also a bit of a mystery!

Anyone else seen anything like this...

Have you any pics? I'v noticed some strange artefacts on long takes.
I did some sensor heat tests wich conducted to the green/pink vertical artefact on edges wich was mentionned on an other thread.
Images of your problem would be great.


Thanks

I had the a smiler stuation. Myem was coused becouse of the auto whiteballance. Look at the tint rollout by pressing and holding the kelvin in the touchscreen.

If you file a support ticket and send in a log file we can look to see if anything strange occurred. We can also tell if you accidentally performed an auto white balance like Mike mention (and in the process setting the Tint to a very large number)

Thanks Trent, but wouldn't that just affect the LUT not the RAW?

Correct, the tint is just meta data, so even if you accidentally hit auto-white balance it would not affect the RAW data. How did you determine the RAW data was discolored? Did you go into RAW view? Did you open the clip in REDCine?

If you haven't already please open a support ticket and send in the log and a single frame clip of the R3D in question so we can take a look.

The same color effect occurred to me, though not while shooting; I had inserted an SSD with footage from a previous shoot (and already viewed the footage both on set and in post, which were fine), but when playing back the SSD footage from the previous shoot (shot on the same Scarlet body), the colors were off, as if the Red channel was nonexistent. Using this example, I'd imagine you can rest easy that any color issues are likely only in monitoring through the camera's LCD and not affecting the recorded RAW image.

Like many issues, a camera reboot resolved the issue.

Sorry guys been busy shooting. Maybe I did hit an auto white balance. Can't gaurentee that I didn't. I'll get that support ticket started tomorrow
