  • 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 ,

since 70 days , I make a movie with 2 red (Epic-dragon + Scarlet-X) on the same set , pictures are amazing but problem is fan sound. (New fan on Epic and Scarlet)

It is very exhausting for team and actors on the set.

I think Alexa or Alexa mini haven't this problem of fan sound.

Have you a advice?

Do you think RED can find a solution ?

Thank you.
 
Use Adaptive settings. If you still have issues there's something wrong with the camera... or the sound guy. lol
 
Agreed set fans to adaptive 65 degrees and you shouldn't have any problems.

Hi have your fans cleaned and oiled. But I understand your pain. No matter what people say or we do the fans are an big problem .

And when Weapon is quiter.. Problem solved;) ok sure.
 
Yea, I mostly use adaptive at 70 for general recording, then I use quite adaptive at 65 for when we really need it quiet during takes. The fan has always been my least favorite part of DSMC v1
 
I would suggest adaptive preview, quiet record setting. Not adaptive. The problem with adaptive is that the fan will try to maintain the target temp regardless of fan speed limitations while recording. So it will become louder halfway during the take then get quieter, then louder depending on how long the take is. Had 3 shoots where adaptive was just too loud for the sound guy. Which I get, it's their job to get good audio. With adaptive preview, quiet record your fan speed starts at 13% which is a lot lower then auto or manual and adaptive can do. And then if needed by the heat of the location or how long the take is can only max out at 40% during a take. A slow and lower increase in sound is better then a fast and louder increase in sound. With the newer adaptive preview quiet record I have yet had any sound guys complain on fan noise. I even had a few say my epic's is the quietest they ever worked with so far.

Also I notice with a lot of owners is that they are afraid of over heating so they put the fan up while recording. Which give sound a bad impression, and sound guys like to gossip.

The sound crew didn't do their homework. You have to use the FanPlate and the front fan V1.
Adaptive mode set to 70c. So you get less noise than Alexa.
Done.

I just did a feature where we couldn't keep sound happy. Ever. Tried just about every option for fan algorithms. Adaptive 65 was way too loud, Adaptive 70 just delayed the increase in fan speed and sound. Adaptive Preview Quiet Record had the sensor temp run above black shade spec, and the core temp would eventually climb north of 72, since the fans don't actually spin up soon enough before another take (even with no post delay). And it would then get too loud to keep the camera from overheating.

Our sound mixer insisted on us using manual mode, so 25 record speed and 65ish standby. Still get complaints on occasion from sound during takes, and from everyone else in between takes.

If you have a very quiet and/or very hot location, sometimes you're pretty stuck - especially if you have longer takes and minimal reset time between takes.
 
Thanks a lot for all your advices.

Sometimes sensor is very hot , do you think It can cause damages to the camera ?

Thanks.

Kevin, why didn't you try the Fanplate?

Unfortunately it's not my camera, and I don't make purchasing decisions. This was also the first time in years I've had such pushback from sound team. I do think it was an outlier in terms of a dead-silent location (a secluded house on top of a mountain), large echoey rooms, and back-to-back several-minute takes.

What temperatures are you seeing? The camera will kick the fans on high, and eventually shut down before any damage is done, so I wouldn't worry too much.
 
I've had audio ask me to set fan setting to auto...and max recording to 25%. Also make sure your AC/OP/DP blackshade. It sets the image to the temp you need it to. (in a crude way) Also....even at 4:1 it took a scene on a Dragon more than 10 mins to get it to where it blew the scene. With an Epic it's about 7 mins. Just adding my XP. But seriously make sure you blackshade and set the fan control to auto with 25% or manual....and absorb it. Or tell audio to eat a dick(as most producers and directors do anyway)....they are already so finicky. But they are your last wall of defense....if you relegate them to "not-important" they might walk off. But seriously...."Hold for audio...fight for justice

Part of this noise problem lies in the nature of the location. If you can find a way to control room reverberations and shield the camera from the actors -- perhaps with sound blankets on C stands -- there might be ways to at least control the reverberation of the camera noise. In tight quarters, I've heard the fan noise on Alexa's, too.

In truth, iZotope and other post tools can knock down a lot of noise issues to the point where they're no longer a factor in dialogue. And on many shoots I've done, the camera noise was the least of our troubles; traffic, airplanes, sirens, trains, trucks, and other problems were far worse. Too often, poor locations get chosen because of low cost. Producers wind up spending lots of money in order to solve sound problems that wouldn't exist if they had chosen quieter (but more costly) locations or sound stages. This would be an example of producers tripping over dollars in order to save pennies.
 
Try using the 1.0 front fan instead; ask your bomb squad rep for it.
You will also need to get the Epic MX front grill, the ones that read EPIC on the coin.

This would be in combination w/ the top fan.

A big matte box also helps block the sound from shooting onto the talent.
