Thanks to everyone who responded. The GPU was replaced by Apple already. Throttling back the render speed to 5 seemed to take care of it for now, but I haven’t tried it on 4K or anything too taxing yet. I’ll try the fan control option and keep an eye on the heat.
thanks again,

Sorry, but the 3700 doesn’t shoot 60fps. It tops out at 30. Bummer, I agree.

7.6 is a realistic focal length. 4.5 is super wide, but not yet fish-eye.

I’ve had this happen once, but was unsure of the cause. Shane, how certain are you of the dirty connectors theory?

Hi, Tim,
The most important thing to remember about MRI is that the magnet is always on. The tech assisting you may not even let you into the room where the MRI scanner is, but if he/she does, don’t take anything metallic with you, or you may lose it. Don’t take your wallet or credit cards in the room because they may be erased. You won’t be able to light the MRI scanner because the magnet will drag the light across the floor and they will have to take the scanner out of service until a repair technician can pry the light out of the scanner. I’ve seen pictures of a walker jammed in one and it was enough to convince me.As for the camera, you probably won’t be able to see a picture once you stand on the threshold of the room where the scanner is. Getting the camera within six or seven feet will most likely erase all the data on the cards and the firmware–everything, assuming you can even hold the camera that close. In other words, don’t try to bring your camera in the room with the scanner. Shoot through the open door as the patient gets situated and through the glass where the tech sits & operates the scan.
CT scans are like most X-rays and flouroscopy. You can be in the room with the scanner while it is scanning the patient, but you should be wearing a lead apron. It won’t hurt your camera if you want to lock it down and leave the room during the scan. Like the MRI, you can shoot through the glass pretty well, but unlike the MRI you can light the room all you want.
Ultrasound, bone density scan (Dexa), are easy and no special precautions are necessary for you or the camera. PET scans have the same precautions as CT, though the patient is mildly radioactive!
You didn’t mention it, but if you happen to shoot radiation therapy like for a cancer patient, you won’t be in the treatment room during the treatment, but you probably don’t want to leave your camera in there whenever the beam is on. They put cameras in all the treatment rooms for the tech to monitor the patient and all the cameras I’ve seen have dozens of dead pixels for some reason.
Hope this answers your questions.

I have the same problem from time to time using P2 formatter for the Mac. I noticed that restarting the computer fixes it for a while.
This isn’t very helpful if you already have the format error, though.

If the sound is loud enough, it will overdrive the mic capsule. Then it doesn’t matter how low you turn it down. If you can’t connect a wireless mic to the soundboard the CD is the way to go. Come to think of it, I think I’d prefer it anyway so you get all the music whether you’re rolling camera or not.

Unless your camera is colder than the ambient temperature, you’ll have no condensation. But all night in your cold car will deplete the batteries, including the internal button battery.

It sounds like you’re shooting standard def and you say perhaps the 170 footage was inadvertently shot 4×3. Click the “anamorphic” column in the bin window, which tells FCP to interpret the footage as anamorphic. Then create a NEW sequence as anamorphic and put your footage in again. Does that change it? Does the 170 footage look right, or is it stretched? If it is stretched then your footage was originally shot 4×3.

Does the footage in the bin window show the same compression, pixel aspect, and frame size?
