IMO this camera shouldn't be used with its built-in battery if any accessories are attached that use camera power like an SSD or phantom mic. I believe that the LP-E6 battery is not sufficient to run the camera, much less anything connected to it. I'm not sure if its the lack of voltage or current that's doing it, but the camera is a 12-20V device with a 7.4V battery? Weird things happen to electronics that are starved for power, and running at 12V might help. I have tons of Sony L's here so my solution was to use a dual L regulated thing that gives me a solid 12V all the way to dead. So far not a single issue. A 14.8V V-mount would be even better.

I use this thing: https://www.bhphotovideo.com/c/product/ ... power.html

I hope this post helps someone out there because having your camera turn off halfway through a shoot or loosing footage is devastating. In my experience this camera is very reliable when supplied with the recommended voltage stated in its specification.

That’s the Sony sled I had pointed to previously so I agree completely. B&H Photo May be adding the 15mm LWS Rod Support (can’t recall if that was included by IndiPro or added by B& H).

The other budget option will likely be my approach initially using the Cinegears 250Wh V-lock battery 12VDC D-tap since that doesn’t cost me anything more.

So after a few weeks of owning the Pocket 4k with the provided AC power cable working perfectly, mid way through a shoot today, I removed the AC cable whilst the camera was powered on with a battery inside the camera. The camera remained powered on but since then, the camera isn't recognising the AC cable and it won't power the camera.

Has anybody else had this issue and can help me find a fix?

You can contact the support office for a replacement power supply.

I'm having the following issues:

1. The camera doesn't always recognize my Samsung T5 SSD 500GB. I've tried connecting and unconnecting, using external power, etc. So far, I don't see a pattern for the failure, except that it always recognizes the 250GB version of the same drive. Maybe in this case it's a drive issue.

2. The Blackmagic Camera Setup software can't see the camera when I connect it to a Windows computer USB 3 port--I also get the message from Windows saying the drive is not recognizable or malfunctioning. This issue concerns me the most since I can't make future firmware upgrades without this capability. I'm going to try connecting the camera to an older laptop with a Windows USB 2 port--hope that works.

All for now...

I ve got the exact same issue on my first shoot. It was an interview so I immediately connect the 12V charging and change from SD to SSD, but at home it was all working perfectly fine.. I think that original battery that comes with camera is a total crap.. when i tested it works better with original Canon batteries from Canon 6D

How hot are other people’s pocket 4K running? When I run mine the screw mount on top gets almost uncomfortably hot, just checking to see if that’s normal compared to everyone else’s :)

Yup this is a problem. Using a full cage “solve” the problem though, since you don’t have direct contact with the hot parts. It also seems to depend on which format and framerate you record. Going 24fps seem to be quite ok in prores, but shooting 60/4k is quite taxing. I recommend getting a full-cage only for that reason alone.

I think the top and bottom mounts are part of the cooling system, adding to the heat sink. When attaching a cage, you are extending the heat sink into the cage also.

Getting hot does not equal over heating.

If the top and bottom plates are part of the heatsink then it's quite a smart way to improve cooling, the alternative would have been lower specs or a louder fan, I'll take the heat!

We have just received our BMPCC4K few days back and here are some of our issues:

1. if we want to playback our recorded clip (in Prores) the LCD screen is filled with red and white lines... thankfully it is not recorded on the card - this is only while we are playing back the recorded clip in the camera

2. BMPCC4K was shipped (bundled) with SSD drive (Wyse 512GB)... yet while recording in RAW 4K Lossless it still drops frames... so when the function "Stop recording when drop frames" is ON - then the recording (obviously) stops... it does after 4-5s of recording...
It does the same while recording on SD Card (Lexar 150MB/s)...

I would really appreciate your help on this.

thanks

So... I can confirm that the batteries can hold it for around 30 mins with T5 Samsung. I can also confirm that non-original Patona batteries can hold it 30 mins as well... So I am going for v-mount solution because I have a few 160WHours vmount batteries...

Didnt notice excessive heating but I am in europe and theres a winter here now so...

Vit, what frame rates are dropping frames? I assume you were recording in 4K 4096x2160. It should be fine up to 30 fps. If you are recording above 30 fps, then use raw 3:1 or 4:1.

Did you format the Wise SSD using the camera? Did you format as ExFAT or HFS+ (journaled)?

Are you using anything like an LED light on, or very close, to the camera? Or any other electronic device. The reason I ask is that some can create interference on the LCD screen

You can't record RAW 4K DCI Lossless onto an SSD, only CFast. - I take that back, I just tried it again and it works fine. I don't know why I thought it wouldn't record lossless to an SSD.

Edit: I forgot to mention that this is at 24fps, I'm not into doing everything in slow motion (which is what I see in every BMPCC4K YouTube example), so don't use 50/60fps all that much.

Ad 1) seems you have the focus assist activated and that's what you see during playback

Ad 2) you haven't specified your exact settings, but you can't record 50 or 60 FPS lossless raw on any device available, the bandwidth exceeds the available bandwidth of the SATA 3 channel.

I've had issues on a couple of shoots now.

1. The camera doesn't always turn on with external power. I'm using a juicebox magic power 2.0 with a dummy battery. This may be user error, but it's now happened twice.

2. The camera doesn't always recognize the T5 500gb drive.

Luckily both of the shoots that my problem happened were for friends, I can't imagine this happening on a paid shoot. I was hoping we'd get a firmware update for Christmas... then for New Years.... I don't want to buy 10 Canon batteries and a CFast card only for BRAW to get released.

This could well be due to the dummy battery not performing as it should, which is why Juicebox is working on a cable connector. You'd be better off getting the Blackmagic cable pack, so that you have the proper power cable as well as a D-Tap in case you go for a V-lock battery in future.

Every time that I see this, it seems to always be the 500GB SSD and not the 1TB having issues. I have two T5 1TB drives and neither fail to be detected. But then, once again, it could also be a power issue.

I suspect that even when BRAW is released, it's not miraculously going to give you six hours of recording from one in-camera battery or small power bank. You're still driving a very large LCD as well as fans, at the very least. Start thinking about something like this (260Wh): https://www.powerstream.com/BP-60.htm or this (84Wh): http://www.powerportstore.com./DC_Products.htm.

And here's something directly from the video store: https://www.bhphotovideo.com/c/product/ ... ttery.html. But there's nothing saying you can't make your own with a V-lock battery, V-lock plate and carry bag.

BMPCC 4k issues

PostWed Jan 02, 2019 12:40 am

Yeah I was thinking of BRAW so I could just get a smaller cfast or even sd card to eliminate the no card issue. The camera always turns on within say.. 60 seconds. It’s just nerve wrecking. After the power issue is when I see the no card problem so you may be right about that. Thanks for the feedback.

It's not up to Blackmagic to do, you'll have to find an external NVMe enclosure that is compatible with the Gen 1 USB-C port on the BMPCC4K.

I think I found why is screen became burned in some cameras. I think it’s overheating. Noticed today that screen temperature at opposite sides are different. Left side has 37 degree Celsius (98,6 F), and right side 33 (91,4 F) . And it’s after 15-20 minutes of just working , without recording.

Re: BMPCC 4k issues, no image on recording

PostWed Jan 09, 2019 3:53 am

I just got my BMPCC4k today after a loooooong wait. But I cannot get any footage I take to play back, its just black. I've tried different codecs, different resolutions and compressions, different lens, different media (Samsung T5 and SanDisk 64gb) formatted the media, reset camera to factory, tried play back in camera and on my iMac...nothing helps. I get audio, I can get the DNG raw stills, and I can get photos with the photo button, but nothing else. Anyone got any advice? I'm really hoping its just some user error or an easy fix. I do NOT want to have to send it back. I already waited 3 months for it! Thanks in advance.

Jared -

Are you saying that you cannot play back the footage in camera immediately after taking it... e.g. pressing the play button on the bottom right on the back of the BMPCC 4K? As long as the camera is detecting your media (which it sounds like since you can see the DNG files, etc), it does unfortunately sound like a camera issue if you can't immediately see the recorded footage on playback.

Not sure where you are located however I had to send my BMPCC 4k back due to the XLR port not functioning and I received a new replacement within 10 days. I'm based on the US East Coast and sent it to BMD's support location in California after receiving an RMA from BMD support.

Jared, you need to contact your regional BM Suport Office and get a RMA to have this issue checked. As Al stated, this should not be happening if yiur recording media is accepted by the camera (no media not working messages). First, have you tried to playback the footage on a computer to make sure the card recorded properly? If it does show up ok on a computer, then it is time for a RMA.

I got a Wise portable 512gb ssd to go on with my BMPCC 4k. My problem is that the camera almost immediately stops recording because of dropping frames. The frames drop at the listed media capacity (4k raw 3:1 23.98 fps, but they also drop at 4:1 and with Pro res at 4k ) . What's wrong? Should I format the media in some special way? It's annoying and it makes the camera unusable.

Gary, try formatting in camera as ExFAT and see if it makes a difference. If not the cards are definitely not right and you should be able to exchange them. They have been tested on the Pocket4K and verified to sustain writing at DCI 4K.

I have it selected as the second option, since as a first option only permits me to choose cf or sd card. But I don't have no CF or SD card inserted

Choose SD card as the first option, then the camera should default to the USB SSD drive, as it seems the USB shares the same bus with the SD slot, from what others have posted here about this issue.

Do you think this caused the frame dropping ?
