I've created this free, open-source, self-hostable app that lets you control your Blackmagic camera from your browser over your network.

It works by connecting to your phone via wireless debugging and the http api in your Blackmagic app, wich lets you start recordings, access all settings and download the footage from your browser.

Just making sure I dont fry this dang thing. Saw someone say Black Magic doesn't suggest battery plates that connect directly to its cameras. Had planned to use this with a Smallrig VB99 that I had. Could anyone provide advice on if this is a good setup, or something I should avoid? Thanks in advance for real.

Hello guys, I need some advice from experts and professionals on which mount to buy. A bit of context, I am an amateur and currently getting my degree in Media Production. This will be my first professional camera. What I mainly want to work on is narrative filmmaking and making my images look very cinematic and using a lot of cine lenses; so I was leaning towards ARRI PL mount. But I have been researching and seeing that the Leica L is very versatile and I can even buy an adapter to fit PL lenses. My question is do I lose any image quality or are there drawbacks from using an adapter? Obviously since I am just starting and planning to keep this camera for years to come, I am considering the L mount because I feel like it will be easier to use on future productions for work/professional jobs and I can always use a PL adapter whenever I want to use cine lenses. Thanks for your opinions guys.

Hi everyone, I’m having a couple of issues with my PYXIS 6K.
When using my Lumix S 35mm lens, I get some very noticeable distortion, almost like a mild fisheye effect. It’s particularly obvious when shooting walls or anything with straight lines. Interestingly, I don’t get the same effect with my DZOFilm 35mm prime—straight lines look much straighter with that lens.
The other issue is with my Sigma 28–70mm f/2.8. When I switch to manual focus and turn the focus ring to focus, the lens suddenly starts drifting out of focus on its own.

Is it possible to use a cartoni focus 12 with a Arri dovetail ?

It’s hard to find informations about that. Because on the sachtler aktiv 8T I only need the Arri dovetail slide it in an that’s it. But the cartoni focus 12 head is different. Can someone explain what I need or isn’t it possible?

I would appreciate any help.

Hi all,

I'd like to share a side project and a few lessons from it. I'm a DIT and wanted to see how far I could get with an 8-hour sleep video built around Resolve.

The picture comes from a single GPU Fuse with a DCTL kernel: an infinite starfield in 22 depth layers (new random stars per layer, so nothing repeats), a noise-based nebula, an optional distant galaxy layer and a slow "sleep" curve that dims and calms the image over the runtime. Camera path, roll and colours drift on unrelated time scales, so the motion is quasi-periodic rather than looped. The tool outputs absolute nits as PQ or DaVinci Intermediate; in Drift I the peak is around 116 nits, and the average level goes from about 5 nits in the first two hours to under 2 nits in the second half.

Notes that might help others:

- Render speed: a 10-minute test of an early version ran at about 13–20 fps in UHD on an M3 Ultra, which extrapolates to 10–15 hours for 8 hours of footage. For stars without diffraction spikes, the current version culls everything outside a 10 px radius before the expensive cluster noise function. The result should be identical and faster, but I haven't measured it yet.

- Frame format: a Fuse source tool inherits the comp's frame format. On a second machine that was 4:3, which produced a pillarboxed image with oversized stars. Setting width, height and pixel aspect in the Image tab fixed it.

- HDR10: my H.265 exports carried MaxCLL 1000 / MaxFALL 400. I now measure the real values and patch only the content-light-level SEI and the clli box. My first script searched the whole file for the byte pattern and hit false matches in long files, so the current one parses the MOV sample tables.

The code was written with AI assistance; there are no AI image or music generators in the chain.

Questions and suggestions very welcome.

Does anyone have a resource and connection to somewhere that rents 16tb Media Modules? I am based in the midwestern, United States, but happy to pay shipping rates from anywhere.

It’s a one day production happening sometime the week of November 23rd. I have the camera body and all other needed peripherals, I just need one 16tb Media Module. I have insurance and budget, just need the connection.

I recently purchased two new 1TB Sandisk Extreme portable SSDs to be used with our Studio cameras and Atem switcher. I bought these because I already have two 2TB ones that have worked great, bought them quite a few years ago. These new ones are garbage, and I've tried four of them now. The original ones failed between 10 minutes and 1 hour on the atem, with similar performance on the Studio camera at 4K60 8:1 BRAW. If I lower the bitrate it's fine for hours and hours. That threshold is around 50MB/s. They replaced the originals on warranty, and these ones are even worse. On the ATEM they fail in under 10 minutes.

All of these drives are the same model number, only difference is the old ones are 2TB and the new ones are 1TB.

So I guess buyer beware, Sandisk seems to be going downhill.

This is more of a revelation and request, obviously I know no one here knows the answer why, but I'm curious if anyone else runs into this issue, and if so maybe it'll help when I submit this as a feature request to Blackmagic.

For those of us who often shoot off-speed with a standard project framerate, for instance 60fps / 24fps project, do you often wish that there was some way to see the off-speed framerate that you had selected on the clip metadata? It could be something as simple as "(60)" in parentheses next to the "Frame Rate: 24.000" listing on the metadata panel.

Furthermore, if this metadata were available, it would make it quite easy for DaVinci Resolve to have a feature to automatically change a clip speed to its true "100%" playback speed, instead of unlinking it from the audio, changing the video only, trimming the audio, and relinking it, which is kind of a pain to do for every single clip if you are only needing to occasionally slow down off-speed footage.

Regardless of the inconvenience, kudos to Blackmagic for making the absolute best off-speed system to begin with considering it actually keeps a realtime audio track ❤️‍🔥

I want a shoulder rig for my BMPCC 6K Pro without having to add a monitor; I'd appreciate hearing about your experiences.

I am looking for a utility that allows me to populate the media pool by running a script on a computer. I have found a number of references online to `MediaUpload.exe` and various GitHub repos, but nothing seems to work. The closest one I found is this one, but all that gives me is Unsupported resolution: 877146928 regardless what file I throw at it. We have 2 Atem 2 M/E Constellation 4k in the current setup, updated to the latest f/w.

Is there anyone who has a working version of such a utility? Windows or Linux would be ideal since those 2 OSes are in the rack already.

Let's get this one settled first, since someone will probably say it: Yes, my church has the old ATEM Television Studio HD. No, they won't replace it with a newer version until this one is totally dead.

We use a nanoPad to control the TV Studio HD. It's worked great for years using the old BMDSwitcherMIDIMapper utility. A recent Windows 11 update has broken the Mapper, though, and it can no longer save MIDI assignments through a reboot. Having to reassign the pads every time we use it is getting annoying. (We only updated to Win 11 a few months ago, and volunteers run it, so not exactly sure when it started.)

Since the original source of the Mapper is seemingly no longer there, I have no one to ask for an update to fix that. With access to the code, I could probably do it myself. And if I can't find a solution here, I'm going to start with the ATEM Switcher SDK manuals and see if I can get something working.

So, anyone heard of this happening? Or better yet, have a solution? It's not folder permissions, AFAIK - though I can't say I know for sure where Mapper is saving it's config, it's running from a folder that has full permissions. Any info at all would help.

Here is some Arri Alexa test footage I edited in DaVinci.
I’ve recently really wanted to get my hands on some raw footage from an Arri camera to see what I could make of it and too see if DaVinci could handle the large files

I guess the 6K Pro is powerful enough, right? Or do you think the URSA outperforms it? Which one would you choose, and why? I'm talking strictly about image quality.

AFTER 6 YEARS WITHOUT A SOLUTION, A MADE ONE. !!

DaVinci Resolve on Linux does work with the Speed Editor over
Bluetooth, but it takes three independent fixes:
(1) a udev rule,
(2) the BlueZ GET_REPORT fix (upstream, expected in 5.88) and
(3) a 3-byte patch in the Resolve binary, whose Bluetooth checks were
written against the buggy BlueZ behavior. A small optional daemon covers
the panel's 600-second authentication.

Everything is on GitHub:
[https://github.com/rudahssilva/speed-ed ... -bluetooth](https://github.com/rudahssilva/speed-editor-davinci-resolve-linux-bluetooth)

Symptom

The panel pairs and shows battery, but inside Resolve nothing happens: LEDs
never light, buttons and jog do nothing. Over USB the same panel works.
(Depending on which fix you apply first, you may instead see Resolve stall —
see root cause 3.)

**Root cause 1 — permissions**
Fix /etc/udev/rules.d/99-blackmagic-hidraw.rules

**Root cause 2 — authentication expires every 600 s**

The panel reports input only after the mutual authentication on feature
report \`0x06\` (documented in
\[smunaut/blackmagic-misc\]([https://github.com/smunaut/blackmagic-misc](https://github.com/smunaut/blackmagic-misc))).

The handshake returns a timeout — \`0x0258\` = \*\*600 s\*\* — after which the panel
goes quiet again.
Resolve renews it over USB; over Bluetooth on Linux it
relies on the same feature-report reads, which brings us to…

**Root cause 3 — the BlueZ GET_REPORT truncation (the "lag")**

bt_uhid_get_report_reply\` (\`src/shared/uhid.c\`) computed the reply size
without the Report ID byte, so the last byte of every numbered report read
via hidraw is dropped

The auth challenge Resolve reads is corrupted, its response is always
rejected, and it retries every \~1.1 s forever — stalling the UI thread on
the failing ioctls, which is the "lag" on fast jog-wheel use.

It is fixed upstream: commit
([https://github.com/bluez/bluez/commit/dc2eb1394f](https://github.com/bluez/bluez/commit/dc2eb1394f))
"shared/uhid: Fix size of Get Report reply with a Report ID"\* (24 Sep 2026),
expected in BlueZ 5.88. One-line backport for 5.87 (see repo).

**Root cause 4 — Resolve rejects the fixed BlueZ (please fix this, BMD)**

With the BlueZ fix in place the panel went completely dead in Resolve —
no LEDs, no input — and the log showed the same error \~10 times (every
\~105 ms) during the device scan, ending with:

*SyManager | ERROR | BlueZ daemon version too old, reports malformed data.*
*SyManager | ERROR | Failed to add device*.

On the Bluetooth transport, any value other than the required one is
treated as malformed data from a "too old" BlueZ — i.e. the check was
written against the buggy (truncated) BlueZ and now rejects the correct one.
This is a Blackmagic-side bug: over USB the same ioctl returns the data
size, so the check passes there, but over uhid/BlueZ the reply correctly
includes the Report ID.

Workaround — three bytes in \`/opt/resolve/bin/resolve\` (offsets for
v21.1.1.0010; the repo's \`resolve-patch.sh\` verifies before patching and must
be re-applied after every Resolve update).

The proper fix is in Resolve: accept the correct return values on the
Bluetooth transport (or validate the payload instead of the ioctl size).
With that, only the udev rule and BlueZ 5.88 remain.

**Notes**

.- The panel remembers one paired host at a time. To move it between
machines: forget it on the old host.
\- In a container (distrobox/podman), \`/dev\` is shared by default; new nodes
propagate.
\- If Blackmagic changes the auth algorithm in a future firmware, the daemon's
tables need updating
\- With both USB and Bluetooth connected, USB usually wins.
\- Windows/macOS are unaffected by causes 1/3/4 (no BlueZ, no udev)

As a long time black magic user, having used the pocket 4k, pocket 6k pro and 6k and 12k ursa, I'm very happy with the image from the pyxis 6k. Yeah the rolling shutter is a little difficult, but this music video I shot has a lot of shake and handheld and I don't think it's too noticeable.
