I’ve been working on some similar problems. So I’m making an attempt with your example.

The first thing I would do is get the anchor point to be in the center of the type and not on the baseline.

The code is for the anchor point for the type. We are taking the value for the width and height of the text and dividing each by half. Those two values are then added to the absolute left and top (0,0).

I’ll post more as I figure things out.

var sourceRect = sourceRectAtTime(time);
[sourceRect.left + (sourceRect.width /2), sourceRect.top + (sourceRect.height / 2)]

It’s a temporal issue not a spacial one.

It used to be (back-in-the-day) with electronic character generators, you had preset speeds you could roll text at to avoid judder or stroboscopic artifacts. It’s the same phenomenon that makes wheels look like they are going backwards when shot at certain frame rates, with the wheels spinning at a certain speed with the shutter at a certain angle. It’s all about aliasing and sampling errors.

I was told that there is some bad blood between the CEOs of BMD and Atomos. I don’t have high hopes for any collaboration between them.

I don’t know if this will be of any help, but I’ve just recently been working on expressions to manipulate the anchor point position. I have a shape layer box that adjusts its size to some text. I want to transition the box on by scaling from 0 to 100% so it looks like the box is wiping on from right to left. The expression pins the anchor point to the top left of the box and the position is an absolute.

var sourceRect = sourceRectAtTime(time);
[sourceRect.left + sourceRect.width , sourceRect.top]

I built this for a template to import into Premiere so the editor can edit lower-thirds.

How much system RAM? I’m assuming the 8GB is the GTX 1050. Also, if the Nvidia card is driving a large display, that could be using up the memory resources.

Can you drop your display down to a smaller footprint and retry the render?

I see on the FAQ, this: “OctaneRender also requires a minimum of 8 GB RAM, and we recommend 16 GB or more.”

[Scott Thomas]

We’re only looking at the preview and not the final render, so it’s a little hard to judge. There are no lights in the scene, so we’re apparently only dealing with the single “default” light, so it’s probably not that.

My first thought was perhaps the flat sides of the box are not planar, but that’s probably not the problem.

I’m guessing that there’s a reflection map is the surface material that is generating the line. That same line is seen in the material preview.

I started looking up what the Cisco product is. I’m still not exactly sure what its intended use or customer base is, but I did note this… “the pricing for a three-node HyperFlex cluster starts at $59,000, including one year of 24x7x4 on-site support.”

You’re not charging enough Bob. ☺

In reading more about “hyperconverged Infrastructure”, it seems to be more about datacenter needs. It sounds interesting, but I haven’t seen examples of a production house using them in content creation.

The Sonnet has a 650W power supply compared to the Blackmagic’s 400W. That probably limits which GPUs they can throw in there. I found a teardown of the eGPU online…

I’m surprised at how many companies are getting into the “Replay” market.

[Don Walker] “I could go back for one day. I think it would be fun……”

I have very fond memories of my hybrid Analog Digital room. I had three BVW-75s, connected via component to a digital switcher. GVG-1000, 1 Channel of Kaleidoscope, Leitch 2-Ch still store and a Quanta Delta. Everything digital, apart from the tape decks. The editor was a GVG-251. I don’t want to go back, but yes, a trip down memory lane might be nice…. As long as there isn’t someone taking note that I don’t remember the K-Scope menu tree. (Remember the big poster of the menus?)

I might do better with an Abekas A53-D. It was all Noun – Verb. I would have a better chance there. ☺

Fun note, at NAB I met a guy, close to my age, who worked on the Grass Kaleidoscope team in the late 1980s. He’s now building playout servers. Nice to shake the hand of someone who worked on one of my favorite digital video devices.
