Playback issues on new Pocket Cinema 4k

PostSun Jan 06, 2019 4:18 pm

I just received my Pocket Cinema 4k in the mail and when out trying to shoot test footage I’ve been experiencing a playback issue. On multiple SD cards when I’ve tried to play the footage the image on the screen flickers between whatever the camera is currently pointed at and whatever footage was shot. I’ve plugged the SD into a computer and the footage plays back fine there which causes me to believe this is a hard wear issue. Does anyone else have this problem/know what to do about it?

When you go from Record standby to playback, the camera does a soft reboot, so the screen flickers between the two settings, and goes black for a moment when going back to record. This is normal behavior on BM cameras.

Hi Kristian,

just received my camera (firmware 5.2) and having the same issue on both my cards:
SD: SanDisk ExtremePRO SD XC II 300 MB/s 64GB
CFAST: Transcend CFX650 128GB

The flickering appears in all PRORES codec and resolutions, but only on camera: downloaded files are good.
Instead, all RAW playback (no matter what compressions or resolutions) are ok.

Look at this video: the clip was recorded in 4K Prores 422HQ, 25fps, Shutter 180°, iso 500 on CFast


Can you help me, please?
Many thanks

Ah, I see now, the flickering is occurring during playback. Me thinks it is time for a RMA, I would recommend you contact your regional BM Support Office, this is ?Not normal playback behavior.

Hi All, I just called Blackmagic about this and they said to only use their list of approved BMPCC4K card, which is different from the original pocket camera. I was using the SanDisk Extreme Pro and it recorded fine but had the playback issue. So we can try that before doing anything else.

We're only using SD EPs and they work perfectly. FWIW we only use the "3s"

Yes, you need to use one of the official SD or CFast 2 cards to verify it is the camera and not the card yiu are using that is the cause, to get BM Support to take it back.

Having the same playback issue. Using the Samsung T5 500gb for ProRes 422 and lower. Playback is glitching with lines and blocks on the device only. On computer all media looks good. Just got the Pocket 4K last week. Bad batch? Anything from bmd support?

Thank you all, but I'm not at all convinced by that answer.
In my opinion, a recommended list of cards doesn't justify that an out of list card causes that kind of issue.
From an out of list card, I can expect frame skipping or recording stop, but not a camera hardware/software issue like that.
In fact, booth cards works fine: files on PC are Ok, and the CFast works perfectly on Ursa Mini 4.6k.

I wait for an official answer.

I'm using some of my old (unsupported) SanDisk cards in my new Pocket4K aswell and I'm not having these issues.

If your issue is with the Transcend CFX650 128GB too, then their seems do be indeed a problem with the camera itself, because that CFast2.0 card is fast enough.

Well, if yiu do not want to go through all the BM Supoirt hoops, then send the camera back the defective camera to the retailer for replacement. ;)

I phoned Blackmagic UK and sent the video by mail: they immediately open an RMA and ask me to send the camera back. They asked nothing about the card model.
I will let you know.
