Blackmagic Forum

I am very disappointed. So many shortcoming on the BMCC. Stuck on dead pixels on my brand new camera. I might have receive a bad sensor or something. After 30 minute test, the camera body is really warm, but the SSD is pretty HOT. This is not normal, I hope. The Dead pixels "white color" on prores and raw, at tested 800iso can be seen on all shots. These white dots can be seen in daylight around the shadown area. I am returning my unit. I will give it another shots on a replacement. But this is scary how bad BM's quality control really is. Hope the camera is build to last.

Could you share a DNG with the issue?

no that is to much work. I search on forum and there are two post that have the same problems with sample pictures. They call it hot pixels but these looked dead to me. They are still in the same spot after camera reset. I am trying new firmware to see if problem go or not.

More work than sending it back?

All the instances I have seen on this forum have either been practically invisible or due to footage being pushed too far in post.


It takes no time at all to share a single image file, and it could save you having to send back your camera.

See if this thread is of some help:

I sure this is a sensor problem. Will send back for sure. If second unit is has same problem I will pass on bm. Let hope that I got a defect cam, at 2k price is to good to pass. FYI firmware update does not help. Will upload picture later just so other can reference to.

Please let that picture be a DNG and not just a screen shot.

Hi, have the same issue with my cam !
Its possible BlackMagic repare the mapping function on the camera in a next firmware or have to change the sensor...???

Most probably is the sensor, blackmagic pocket cinema camera has blooming sensor issue as well there is a whole thread dedicated to it. really poor quality control from BMD. then again you get what you pay for.

First, HOT pixels are white. DEAD pixels are black. STUCK pixels are either reg, green or blue. Read up more here: http://photographylife.com/dead-vs-stuck-vs-hot-pixels

Second. The body of the camera is SUPPOSED to get warm. It's part of the cooling function. That is normal. Also, your SSD will get hot if you record to it. Depends on the brand SSD, some get hotter than others. Perhaps you have an SSD with less built-in heat dissipation. What SSD do you have?

Sorry I did not have time to update. It is crazy but those white pixels disappear the next day. I did another shoot before returning it and on one instance I notice a white dot appear on some shots. These are random dot. Had to rerun anyway. Now more waiting. I am using sandisk extreme I 240gb.

By the way I love the image quality and for the price, nothing come close. Also I did notice banding on low light shots. I read somewhere here that only happen to a few camera. I really think I got a bad one here.

Looks like I got one too. Has anyone returned their camera and received a replacement? Wondering if it's worth sending it in. Is this common. Shows up on 200 ASA/ISO 400 ASA/ISO 800 ASA/ISO and especially 1600.
The images above is from 800 ASA.
Thanks in advance

The white dots and banding sounds wrong to me, but see what BMD say.

My fourth replacement camera was RMA'd by BMD and confirmed faulty after several months of working fine - then one day we did a comparison test between prores, dnx and raw - something happened and then we had lots of single frame hot pixels, several dead pixels, serious banding on any area that wasn't over exposed and the sensor split became extra prominent.

I don't own a BMCC anymore but I still admire the picture out of it when it does work. It has just shattered my trust in the 2.5k version - three out of four of of the cameras I had broke. Of those three, two due to sensor problems. The first one bricked due to the dnx/prores bug about a month before the fix was created. BMD were very helpful in trying to get things sorted for me. I guess I was just unlucky.

I know a lot of people own BMCC's that haven't had issues, and I'm encouraged by this. I'll be renting the camera in future though.
