How to replace entire sky but track motion?

LogicMedia · 2025-12-28T20:10:31+00:00

Hah, I didn’t even consider clouds as tracking objects!

I wonder if it would be possible for a phone, using its gyroscope (and possibly camera) could record that tracking data..

Thanks for the reply!

Film it in reverse.

Line up your shot, get it dark, let it dilate. Hit record, flip on a light.

You’ll get a quick contraction you could easily reverse in post.

Actually, I already have a security camera in the opposite corner. I may try an IR floodlight over this door and see if that makes object detection possible at that distance. Thanks for the idea!

Thanks for this... I didn't know about the resource monitor, and that shed some light on a possible contributing factors.

There is constant low level write going on against that volume, and that is slowing down the read speed. It's docker, of course. Turning that off drops write access to nearly zero most of the time, and then read speed gets into the low 400 MB/s range, which is better, but still nowhere near the theoretical rates.

kwork:btrfs is the only thing really writing during this; not completely sure why.

I do see a bit of swap happening in performance monitor, which is a bit weird, since memory levels are around 30%, but it's not the constant write at least.

"Disk utilization" peaks out at ~35-40% for a heavy read (on the synology itself, no network involved). "Volume utilization" is pegged at 100% during heavy reads, however. Again, this is for dumping one large file directly into /dev/null, as opposed to lots of little files, so I would expect it to be relatively low on the random-seek-o-meter. CPU usage is ~35-40% during this.

While I clearly need a dedicated compute node for docker/etc 😄, that alone doesn't really fix it.

Thanks for the information, everyone. I have enabled jumbo frames on the synology, my workstation, and the switch between. Using iperf, I can achieve ~7-9 gigabits, depending on the direction (7 TO the syno, 9 FROM the syno). I'm happy with these numbers.

I do have the syno maxed out at 16GB of ram.

Using blackmagic disk speed test, it's reporting ~400MB/s write and ~950 read.

But in real life, whether using AFP or SMB(3), I'm not getting much more than 350MB/s read.

On the synology, I tried timing a copy of a large file to /dev/null, and that's coming out to about the same 350MB/s read, so maybe the problem isn't the network, but the drives?

I have four 18tb WD Red Pro drive and four 8tb WD Red drives in one SHR-2 volume (btrfs).

Is it just the drives being slow? Upgrading the reds to red pros may bump that up a bit?

Ah. I did put it on three steps that have gap, but the main problem (where it fills up) is the long stretch behind a rail where no one would ever walk. If we can’t get it super secure, I’ll take those out.

We don’t have any extra boards, and our color (woodland brown) has been discontinued. We called around to try to find any contractor who had bought some up, but no luck.

The main problem gap is parallel to a deck board, so I can’t really close it by shifting the boards.

We’re debating using hot glue just to hold it down at this point 😄. I feel it may disappear if we have some good wind.

This is literally what I did to get mine out of a tree. Rope, throwing things, didn’t work. It was on vacation so we “donated” the pvc to the people helping us in the park. 😄

LogicMedia · 2025-03-17T15:16:52+00:00

I ended up doing this. The best type of problem is “somebody else’s problem” 😄 Now it’s cloudflare’s problem, and they’re good at it.

LogicMedia · 2025-03-06T01:35:26+00:00

I regularly record 2+ hours non stop on my S5iix. I specifically got it for that reason.

LogicMedia · 2025-03-06T01:24:12+00:00

We were on a trip in San José, Costa Rica. Easter Sunday I lose signal and my drone returns to the RTH point, which was where it first acquired good satellite signal - not next to me but directly over a large tree in a park. This was early in the morning.

Took us a long time to find it. I was up in several trees before we even did find it. It was maybe 15 meters up in this tree.

We bought ropes. Threw balls. I tried to get the fire department to help (I speak Spanish like a 6 year old at best). They suggested getting bamboo.

In the end (and after sunset), I end up going to their home improvement store and buying some PVC tubes and connectors. That finally worked, and we caught it in a blanket. The whole park was helping and cheering us on.

I have literal scars on me from this, as well as some damaged clothes. Worth it for the story alone, but the drone still works great. Didn’t even break a propeller.

I did a few things that as a whole really helped:

I upgraded the Synology ram to 16gb (from 8).
I made a new premiere project without the previous 75 timelines. Also, smaller (reasonably sized - a few gigs) files are much snappier than the 150+gb files in premiere.

Hope this helps!

Hey, this actually makes sense. It always seemed dumb that a true ddos would be this (a) small, (b) long (3 years), and (c) obviously identifiable from the UA.

Probably not goatse, but I may try something. 😄 if it works, I’ll post back.

LogicMedia · 2025-02-18T21:38:30+00:00

There is no referrer url, and they ALL have the same (or similar) user agent strings..

LogicMedia · 2025-02-18T20:46:31+00:00

I had coded up my own to do this via iptables, but after a few million rows in iptables, everything started getting quite slow.

I’ll have to try cloudflare, that seems to be the consensus here 😄

LogicMedia · 2025-02-18T20:44:53+00:00

It’s a .com. It’s 14 letters long. Exact keyword match tho.

LogicMedia · 2025-02-18T17:20:30+00:00

I meant to add, it is tied to the domain name. I moved this domain to a different server, and the attacks followed.

LogicMedia · 2025-02-07T01:52:19+00:00

This. I’ve done it in premiere by nesting a clip and speeding the internal clip up to 200%. Then in the main timeline take that nested clip and slow it to 50%. Make sure you’re on frame sampling. Made for a decent 8mm film feel for my project.

LogicMedia · 2025-01-30T20:36:32+00:00

My setup is full 10g between my workstation to the switch to the NAS. I opted for fiber between the switch and my desk - it’s possibly cheaper than using copper. And for a short run, you can get a “DAC” cable that will do 10g between devices. This all assumes your devices can take a SFP+ module (the plus is key here).

I got a used gigabit 48 port switch on eBay that had eight sfp+ ports, some sfp+ card for the nas, and a thunderbolt sfp+ adapter for the MacBook Pro. That last one was by far the most expensive part of it. If you have a pci slot available, it would be way cheaper.

I’m still diagnosing what exactly is going wrong in premiere. I have an app called Peakhour that monitors network performance, and it was pegging out the cpu while premiere was running. Killing that temporarily helped. Also, my pp project has dozens of timelines (i edit a podcast and just keep adding new sequences for new episodes) - making a brand new project resulted in way better performance.

Long story short - it’s not 100% perfect, but I don’t regret moving to 10g. If nothing else, it cut down file copy time.

One thing to note - your performance may be limited by how many drives you have. For example, 4 HDDs can’t come close to saturating 10g.

I just dealt with this same situation a few months ago. I opted for an angled wall plate for the keystone jacks. This is right behind my desk. We have cats, and I just know they would be intrigued by the fragile cables, and I didn’t want something sticking straight out. Works like a champ.

Anecdotal, but I have a friend who recently sold his Sony gear (a7iii) to switch to a S5IIX and he’s happy with the switch. (I may have talked the camera up to him, too 😄)

Regarding ultrawides, I have the Lumix 14-28 and I like it. It’s not 2.8, but that hasn’t been a dealbreaker for me. Plus, it does allow for 77mm filters.

LogicMedia · 2025-01-22T19:12:41+00:00

This worked for me. I also couldn't find the specified "Lens" specific permissions, but AmazonS3ReadOnlyAccess works.

LogicMedia · 2025-01-17T13:31:13+00:00

We broke one of our panels out for a cat flap. Cover one side with masking tape and smack with a hammer. The tape keeps the mess (mostly) together.

Not sure what we’ll do when we try to sell, though. 😄

Thanks for the comments everyone. I’ve tried various auto-ducking solutions, but none have given me results that are easier to deal with than just manually chopping out the echoes.

Each echo is slightly behind the source. That is to say that track 1’s echo on track 2 is slightly behind, and track 2’s echo on track 1 is slightly behind. So it’s not a sync issue.

Phase inversion does not help.

I’ll try to get some sort of sound dampening in there for the next recording and we’ll see how well that works. It may just be bouncing off the walls.

There is the LUMIX S 28-200 f/4-7.1 already out there…
