Thermal Shutdown!!!

[Jeffrey Loewe]

How were you shooting 1fps?

I learned this after the fact too.

Hold down the Frame rate in the upper window and a calculator will show up, or well the choice to enter it will be, then click in there again and a calc screen shows up.

Right i knew this on the epic.. But did not know it really went down to One frame.. Sweet.Lets hope the redmote can do this for me

When the camera gets to 75c, the fans automatically switch to high regardless in manual or auto. I keep my fan at 30% in record, 85% standby.

Thanks. Great to know. But maybe this is a metric thing? You say 75c, yet the Scarlet op temp range in the manuel says 0-40c. At the highest, my scarlet hit 52C, till I noticed, and had to stop filming to cool it down. Yet, you say 75C? Mine was nowhere near that when the dot turned red. Also: ANYONE, know how to change to Fahrenheit? I just don't relate to Celsius. Freezing is 0 and boiling is 100. But I have no reference feeling for celcius. Thanks.

F= 1.8C + 32 In words: to get Fahrenheit, multiply Celsius by 1.8, then add 32. One other useful equivalence to remember is body temperature. 98.6F = 37C

So 40C is a bit higher than body temperature. Common sense would then tell you that the operating temperature range of 0-40C refers to ambient, or room temperature, not the internal temperature of the Scarlet.

Also, blowing air INTO the top vents doesn't make a lot of sense since that is an EXHAUST vent. By blowing air in, you are working against the fan.

Processors generally don't melt until they hit 100c+. Even 75c fan turning on full blast is probably a conservative heat limit. Unless the processors in the Scarlet/Epic are using insanely new fabrication process (e.g. smaller than 32nm), I don't see the camera actually getting damaged from running at even 75c for hours on end (i7s on stock air cooling probably hit 85c under full load and they can be rendering for days.) I know it's apples to oranges, I'm just trying to show a little perspective.

Conversely, if the camera is auto-shutting down and it's only at 40-50c, that's a big problem as it interrupts shooting and shouldn't be happening.

I did testing with mine to see how low of speed I could roll while recording a whole card and 72c was when the temp turns yellow, 75c is when the fans kicked into full. Cooled down camera from 75c to 46c in 5 minutes.

Recently did an 11hr day in an enclosed 10'x12' room with tungsten lighting. Camera essentially wasn't powered off other than 40mins for lunch, moved from AC to side handle battery and back to AC, swapped batteries while plugged to the wall. Ambient in the room was around 90F with the lights and bodies packed in. Epic-X was fine ran, in the 54C/130F range for internal temperatures. Dialog heavy, fairly standard narrative shoot, takes were usually around 5-7min, a few 12+min takes.

Camera was ready and willing to keep going at the end of it. Me, I needed some sack time and a gallon of water...

Yes. I have a app for the math, but like reference price for gas prices, I don't concepilize celcius; make sense what you say, but why red indicator at 51ish celcius?

And I was trying to blow air OVER the vents. Venturi effect; like shower curtains moving inward while taking shower or blowing over glass coke bottle creates vacuumed inside coke bottle.

, draws air out the top vents faster. But was also worried about dust. - and any suggestion on how to cool down and fast?

Thanks.

Thanks.

If the camera is giving you an overheat warning at 51c, then you don't need to be posting here, you need to write a log file and file a report with Red. HERE (I'm assuming that you've already tried re-installing firmware.)

You don't really need to know how to cool the camera down fast. That's the wrong problem to solve. You need to know how to keep its temp constant, so that's never necessary. The suggestions in this thread and others should help you with that, but now you've got to learn the camera. Red cameras produce a lot of heat because they handle a lot of data. Heat management is part of your job.

Hi Steven,

Please save a log file from your camera and send it to RED SUPPORT here https://www.red.com/contact_us/new. Our engineers will diagnose the log file and our tech support team will assist you with troubleshooting.

NICK

Thanks Nick, I have a full day today, I will send the log file this evening. My first thought is user error, that is why I came to the forum first.

Wow, its not just me...

I was shooting a few 10 min interviews, when part way through the third interview in a basement, at about 70F, with no heat from lights, I noticed my Scarlet Heat indicator (the little red dot next to the temp) turned to red.

The red dot is NOT an over temp indicator. It is a red clipping indicator.

 

[Gavin Greenwalt]

and HOW THE HELL DO YOU CHANGE the temp from C to F?

You don't really want to. What temperature it actually is is mostly irrelevant. I like computers in celcius because if you think of it as how hot you want to be in farenheit it translates better.

"50c, good thing I've got a little heater to keep me warm."
"75c, warm, could use a little AC"
"100c, too fucking hot, need AC"
"120c, dunk me in ice water please!"
