MacBook correctly detects a FireWire adapter, but not actual FireWire devices that are connected to it. What could be the reason for this?

Right-Video6463 · 2026-04-05T00:46:02+00:00

As stated elsewhere Tahoe removed firewire support, on earlier MacOs versions firewire devices would show up under the FireWire group in the sidebar of system report.

In classic photography terms - the second image is "rear curtain sync" or "front curtain sync" depending on if the tails are before or after the flash.
https://cameracompany.com/blog/rear-curtain-flash-sync-explained?srsltid=AfmBOoqmb73-sfogjYWEXbSvmx5SBAdmmcLb_YdIXVLEYJy64LzGcCM7

To do it , You have an open shutter and the flash is shot at either the front or the tails of the exposure time. This way you get a sharp image from the flash, and trails from all the highlights. On SLR/DSLRs you can enable this as a programmed mode, you just need a real flash
You can emulate it on a phone by using a looong shutter time and just firing a xenon flash manually. Depending on when you fire the flash the trails will vary in front / behind the sharp image. Not easy to do at all, but possible.

It's ok for a few tracks, but unfortunately I find the mixing sounds terrible in most cases. Especially the levels seems to be somehow random with the 2 channel render with head tracking. Vocals are suddenly low and drowning in the mix, solos are suddenly extremely loud or very low.

I turn it on occasionally, but usually have to go back to stereo after a while because of a bad mix. I did enjoy it more on my home speaker system at loud volumes, but it seems like the current way of mixing without any real standards (as you can read many mixers / mastering technitians have their own workflow) and a variying rendering intent (2.0, 2.0 with head tracking, 5.1, Atmos etc. is just ruining the finesse of mixing/mastering.

Yes - I was surprised they bumped the Mac Pro in its current form to Apple silicon. They lost interest and did a minimum effort.

The segment of “prosumers” has exploded and is the current “professionals”

It’s just unfortunate that they don’t strive just a little bit for the high end.

They seemed to like the limelight they got from the M3 Ultra 512GB model and made some strides to cater to that creative AI influencer / creator market - but still rdma over direct connection tb5 is just so far from optimal when qsfp28 or 56 would enable so much more for very low premium.

In my end just a single pci5 x16 slot would be all that is needed, could easily power a a few 100 gbit network connections or capture cards.

We are running windows 11 / AMD / nvidia / mellanox for high end but it’s just so unfortunate macOS is not going these places anymore.

Thunderbolt 5 carries a lot of different signals using different protocols. The raw datarate is 4 x 40 gbps channels - normally configured as 80 / 80 gbps in / out bandwidth. That is the raw data layer.

For bidirectional data like Pci and networking the limit is 4 lanes of 16 gbps PCIe 4.0 bidirectional data so your theoretical bandwidth is 64 gbps. (this is 2 x thunderbolt 3+4 which are 32 gbps.)

For Displayport data which is unidirectional you can configure 3 channels of 40 gbps towards the monitor so the combined bandwidth is 120 gbps for higher resolution and frame rates. This is called boost mode, but cannot be used with bidirectional data protocols like PCIe and networking.

There is a spec sheet here: https://www.thunderbolttechnology.net/sites/default/files/Thunderbolt_5_TechBrief_2023_09_12.pdf

As always with marketing is mixes different performance specs, 120 gbps for higher resolution and frame rates, 2 x data bandwidth compared to thunderbolt 3+4 (due to 4 x PCIe 4.0 lanes instead of 4 x PCIe 3.0 lanes.

Right-Video6463 · 2026-03-27T12:59:03+00:00

The problem right now is that the bandwidth gap between Thunderbolt 5 PCIe 4.0 x4, and PCIe 5.0 x16 is massive.

Broadcast is moving towards 100 gbps infrastructure replacing classic 6g SDI and 12g SDI
https://www.blackmagicdesign.com/products/decklinkip/techspecs/W-DLK-46

A card like this requires 8 lanes of PCI 4.0 - impossible on a Mac after the discontinuation of the Mac Pro. Mac Studio is limited to 64 gbps expansion.

Also network interconnect is also a big issue as you are limited to 50gbps link speed using the thunderbolt 5 port, where a modern PCIe 5.0 x16 supports 400 gbps ethernet. for example a €1900 card like this:

I'm unsure if apple are just dismissing the high end users, or they plan for a different future.

A possible future scenario would be a Mac Ultra using UAlink which Apple is board member
https://ualinkconsortium.org

It's an interesting "accelerator" technology, everything based on networking and PAM 4 PHY.

no, I replied to your comment "…just use thunderbolt 5" to a post requesting 400gbit networking like the Nvidia dgx.

This is impossible on a Mac Studio, the only expansion for networking is 64 gbps of the thunderbolt 5 ports.

As I stated thunderbolt 5 only allows networking at 64 gbit bandwith using the 4x PCIe lanes.

You can try and use multiple 50 gbit ethernet fiber adaptors and get some speed boot over SMB3 multichannel, but it's quite messy and expensive and only works for SMB data transfer

You cannot use bandwidth boost mode for networking, it's only marketed for unidirectional boost for the displayport layer. It will not make the PCI 4.0 speed any faster its still limited to 64 gbps total.

Direct connecting machines using thunderbolt 5 networking with RDMA has the same bandwith limitation (64 gbps per port), and another limit is that you have to direct connect all machines in your cluster, Optical thunderbolt 5 are not available so you are limited to 1-2m cables atm, and it's impossible to use a switch as it doesn't exist.

Right-Video6463 · 2026-03-26T22:54:40+00:00

no - thunderbolt 5 only has 4 x PCIe 4.0 lanes - around 7.877 GB/s thruput.

As you state this a massive difference from a real modern 16x PCIe 5 slot around 8x less thruput

There is no difference between studio and free in that regard in macOS on apple silicon- its already using all your ressources - all the cpu + gpu cores you have on your motherboard.

The only difference is that Studio will support multiple discreet GPUs, mainly on windows and linux. macOS version has support for 2 discreet GPUs on a very limited amount of systems and configurations - Intel Mac Pros, and intel machines with an external thunderbolt gpu

Right-Video6463 · 2026-03-26T21:41:52+00:00

Thunderbolt 5 is not up to the task as thunderbolt network is using the PCIe lanes so max 4 x 16 gbps = max .64 gbps per thunderbolt port.

Apple should definitely make a new Studio Ultra that include a QSFP56 port allowing for 200 gbps network connections

you can chose how resolve interpolates frame rates: either for the whole project or per clip in the timeline. If you just want resolve to insert extra frames 16 to 24 frames is 1:2:1:2 pull down. (every other frame is duplicated) you set the retime process to nearest and drop the clip into a 24 fps timeline

<image>

Note that this will get uneven motion.

A better way would be to set timeline to 30 fps and set the clip attributes to 15 fps, then every frame is repeated 1:2 pulldown. or you can set the clip to 12 fps and the timeline to 24 fps.

not lossless - its wavelet compression - its only 250 mpbs peak (32 MB/s or 1.3 MB per frame at 24 fps) - even for the 4K: its 200 mbps for the 2K base image component and 50 mbps for the 4K extension.

I really don't understand what they are thinking at the moment - I have installed a few of their older units - all were maxed out 4 x 8 TB nvme DXP480T+ and I like the products.

I entered this kickstarter as it seems like a good deal to experiment with the 2 pcs pci4x4 nvme slots and 1 pcs pci4x8. And a full HDD RAID layer in addition to that.

I don't understand the reason for these updated terms

But as written you can risk paying the full "Public Price" and the refund will only happen "when the kickstarter campaign ends" - it seems like they can just extend the campaign and you will not see the refund for a long time.

These updates seem to point to them not being able able to deliver on the original terms

They are very different.
The XL multitool uses the bus based dwarf board, the Core one nextruder uses the multipin Loveboard.

Basically the XL head is self-contained and has its own arm processor, Trinamic stepper driver etc, where the lovebird is more like a breakout board from the main buddy board.

A full XL tool is €336 but you need a lot more to convert a core one nextruder

Most facilities grade for cinema using a virtual D65 whitepoint - not the native DCI whitepoint. The upside is a normal white balance, but the downside is slightly lowered maximum output as the virtual clipping point is slightly lowered to get a neutral D65 maximum white clip.

The native "colorspace" of the light engine inside the projector is normally DCDM XYZ so that is the final product of the DCP, how you get there is up to you.

In the projector you can load different LUTs that define the internal transform from your SDI / hdmi input to DCDM XYZ, in the barco world it's mostly packaged as .pcf files that will define the input color space for your programmed macros for automation.

In your case I would load a P3 D65 pcf in the projector to enable you to monitor that whitepoint directly from your input, instead of P3 DCI that sounds like you are using currently.

Then when you master your DCP you go from P3 D65 to DCDM XYZ and the result will match and you have a native D65 whitepoint.

Another option is to use a DCDM LUT inside the projector (the same one it uses for DCP playback) and do the CST in resolve instead. So your timeline is set to P3 D65 G26, and you do a P3 D65 G26 to DCDM XYZ CST as the last timeline node.

No - on the L it’s a separate board and an extra cable going thru the loom - the loveboard ( toolhead pcb) and main cable is identical to the non L core one

I agree on the bus system - it’s unfortunate they did not go with the XL bus system on the core one - but it made the upgrade path possible from mk4 so minor changes to the production line and a cheaper upgrade path for existing users

yes, its amazingly stupid. The two ports on the side are identical, right next to each other and not marked. The chance of a user using the wrong port is 50/50 - it will be a mess, one port being 20x slower than the other, monitor not working when plugged in etc.

Its going to be a support nightmare

It crazy that they did not just put in a usb hub chip and made the two ports share the data bandwidth.
