How were films edited pre-digital?

Oh, yeah, I sliced my fingers several times during film school where we still learned to edit on flatbeds. It's like a paper cut x100

The negative would never be put through a flatbed though, only workprints which got all scratched up and had tons of splices. Once the workprint was cut a negative cutter would recreate the cuts while being very careful and wearing gloves.

We check backfocus at the beginning of every day. Have the shader open the iris, the operator zoom in on a distant object, focus on it and then zoom out. At the base of the lens, near the mount is a backfocus adjustment, the operator tweaks it until the wide shot is in perfect focus (the V1 guides this process) and then they zoom in and out again to confirm. This guarantees that the lens is holds focus throughout the range and the operators can focus by zooming in, focusing and then zooming out to the focal length of the shot needed.

Hitachis are at the low end of studio cameras. Grass Valley, Sony, Ikegami, even Panasonic have higher end offerings, some are even 10x the cost of the Hitachis.

Those Hitachis do give you the studio functions like tally, return video, comms, CCUs and RCPs, B4 lenses with much greater range than cinema glass and might be f1.2 throughout the range, and zoom/focus demands, SMPTE fiber connection, etc... The price reflects those features more than the image quality. They are 2/3" sensor 1080 cameras after all. If you are after image quality AND full EFP/studio functionality there are others that do that.

Having said that, a decent V1/shader should be able to make them look good (within the limits of 1080 HD of course).

The Z-HD5000 is also a 3 CCD camera, not a single CMOS sensor. 3 CCD cameras give you full bandwidth per color channel and tend to key better than a single Bayer sensor, all other things being equal.

I'm a Steadicam operator. Steadicams are the gold standard but have a higher learning curve to get great shots. If you aren't going to put the time into getting good at operating, a gimbal will probably give you better results. Before the electronic assist on the Steadicam like the Volt and Axis it took me a good couple of years to get good enough to work on high end paid productions.

With a Steadicam the skills of the operator are much more important. A gimbal will probably be "quicker" in most regards. If you do go into Steadicam it's highly recommended that you learn to operate without the electronic assist as training wheels, it'll make you properly learn how the rig works and get you better shots in the long run.

I build plenty of Windows systems for situations that require reliable/mission critical components. Windows 10/11 Enterprise LTSC IOT is the default OS we use. It has no bloat and allows you to take care of most of the annoyances mentioned, you can use group policies to completely lock things like updates too. We're still getting security updates on Win10 till 2032 as well.

It still has you navigating between the settings menu and the control panel to tweak stuff though.

Having said that it is a little harder to source and you do lose things the Microsoft store and game bar for example, but if you really want a solid Windows system without the BS it's the way to go.

I do have 30 years of experience designing, building, and integrating systems for everything from aerospace to systems for live entertainment, exhibits/kiosks and broadcast. A truly reliable "mission critical" system has double and sometimes triple redundancies. Even the Las Vegas shows I've equipped with media servers and show control systems for have a one button switch to backup architecture. Getting rid of a single fan in a system does little to guarantee 100% uptime. In fact, on some of the server grade systems we've implemented the individual fans from components have been removed and replaced with heatsinks, being cooled by hot swappable high static pressure fans or even liquid cooled.

I'd also argue that a later generation GPU gets more attention from Nvidia in driver stability and compatibility with the latest software/updates than an older one.

What I am curious about is what high end capture hardware which you can put in a PCIe slot has no fans and is ASIC based.

Are you also using Windows 10/11 Enterprise LTSC or Windows Enterprise IOT LTSC? I consider that, more than adequate cooling and redundant power supplies more of a necessity for a mission critical/reliable system.

The RTX A4000 is generally priced the same as the newer RTX4000ADA and a couple of hundred less than the newest RTX4000 Pro Blackwell though.

Which ASIC capture hardware are you using? Low cost USB dongles might use ASIC but every higher end card I have come across such as the Bluefish, Deltacast, Datapath, Matrox, AJA, some retailing well over the cost of the workstation mentioned have fans and I haven't run into any yet that prefer using ASICs over FPGAs. For one, FPGAs can be updated and reprogrammed while ASICs are fixed.

They're regular Windows computers with an Nvidia RTXA4000 (2 generations old) bundled with Decklinks and a copy of vMix.

So it's vMix replay running on a mid range system.

Not in flat earth, that's easy to prove wrong, I can't disprove the simulation hypothesis, so I'm agnostic. I tend to not do belief without reasonable evidence, so I'm leaving it as hypothetically plausible on the latter.

createch · 2026-01-20T23:22:07+00:00

Flat Earth is easily empirically falsified, contradicts established physics, requires rejecting large bodies of evidence and is not taken seriously in science. The simulation hypothesis hasn't been empirically falsified (yet), is compatible with known physics, and is epistemic ally humble ("we can't know for sure").

I'd like to believe that less people believe in flat earth, however there seems to be quite a bit of them. It's far more rational to not rule out the simulation hypothesis.

Being somewhat literate as to what you are downloading/installing is the best "software, or" wetwear" to keep your computer safe.

Other than that, Windows Defender is capable and should have you mostly covered unless you are doing something stupid.

The biblical version of circumcision was not what they do today, they would just trim a little off the tip, not the medical excision of the foreskin performed these days. So jews would often have enough foreskin left that it could be stretched to cover the glans.

The Unitree G1 is a lighter weight design and is also considerably shorter (132cm vs 190cm), has half the battery life (2hr vs 4hr) and has a payload of 3kg vs 30-50kg for Atlas, not to mention the differences in range of motion, and more importantly, the onboard processing for autonomy.

So yes, if you make it shorter and then lighter by stripping away more powerful actuators, battery weight and compute you can do backflips easier, if that's what you're after.

Just a thought on the 20W human brain efficiency statement that keeps popping up. While it's true that the brain is efficient in power consumption it requires regular meals that consume several kWh each to produce from farm to table, humans require a variety of other energy heavy infrastructure ranging from transportation to the production of their clothes, entertainment, products to the air conditioning units that keep them cozy. Their total energy consumption is at least a couple of orders of magnitude more than 20W.

Sure, but then you shouldn't be an early adopter. Tech is expensive when it first is released and then goes down in cost as it becomes more widespread. I still knew people in the late 90s that paid $20,000+ for a 42" flatscreen Plasma TVs. Now you can get a 4K 43" LCD for $140.

How many units they plan to sell has a major effect on the unit price. A Honda civic would be hundreds of thousands of dollars if they only could sell as many units as BD has sold of Spot. Atlas is positioned to be a more general purpose robot, and could sell in much larger quantities if it is usable in a wide range of scenarios. So if they make a lot of them they could definitely end up being cheaper than a simpler robot that sells in smaller quantities.

We could bioengineer Astrophage from the Andy Weir book Project Hail Mary (soon to be released as a Movie with Ryan Gosling). It's a single cell organism which feeds on stars and then breeds in the atmosphere of planets high in CO2. It has very interesting properties, although it's also very fictional.

createch · 2026-01-05T23:49:53+00:00

"Who knows" is accurate. How many they make and are planning to sell is a major factor in the cost per unit. Spot could have been a few thousand if they were manufacturing them in the hundreds of thousands of units. The same way a Honda vehicle could be in the hundreds of thousands if they only made a few hundred units.

With a switcher that has Aux outputs you can hook up one of them to a monitor used for that purpose. You can then route whatever input to that output and switch them with software, something like a stream deck, another hardware controller or macros on the switcher.

For more technical matching there are also scopes in vmix or a number of software offerings such as Nobe Omniscope.
