What matters is acceleration, which is independent of wind speed. Here's a graph of the net G-Force on the object in the nearby straight-line, vertical u-turn scenario. This graph is in the current version. Red arrows indicate the rotations, with the longer arrow being the longer rotation...

Indeed there is. One thing that needs discussion is something @Edward Current brought up, maybe a year ago. The non-physical nature of the nearby path(s) Graves says: they turned their return radius right into the other direction, which is how aircraft turn. We have to bite into the air...

And you've always been able to ignore individual users.

There is now! See what you are ignoring in your profile: Unignore there, if needed:

So a new contender for "most authoritative" emerges. Ryan Graves has a new article, and this time includes four mock-up images of the SA page. The GIMBAL object was located between 5 and 10 miles away, while these other objects appeared to be spaced 3 to 5 nautical miles apart. What these...

Probably because they were cached. I use Cloudflare which generally speeds things up. If people are having issues, I normally suggest flushing the cache, clearing cookies, and trying another browser.

Added a "Focus Track" menu option that locks the cursor to a track, making inspection a lot easier, as it will rotate around the cursor and zoom appropiately. Particularly useful in Aguadilla. http://localhost/sitrec/dist/index.html?sitch=agua Also in Agua, improved the smoothing of the camera...

This is all stuff that has been done before. I've done sub-pixel motion tracking with After Effects, years ago. You could measure noise in the normal way (amplitude about the mean, std dev, sigma). The biggest issue is really the lack of data points, combined with the lack of resolution. I...

I do, and I'll probably get around to it eventually. I'm going to write a motion tracking tool for Sitrec.

I have just done so, basically the same email as before.

Usually, yes. You can also use the Google search without leaving the site using the G button: The default site search is more focussed on keywords. The Google search used a more AI, natural-language approach. Like if you search for MEK it knows that is Methyl Ethyl Ketone, and so will return...

Thanks, I guess I should just keep the status as "not on mobile" for now.

I've added a "Load Video" button, which might be easier than dragging and dropping files

Can someone see if this works in Chrome on an Android device? It does not work on iOS device (iPhone, iPad) which is a bit disappointing, as I thought Chrome on those would support WebCodecs. I might have to shoehorn in a different method of loading the videos.

https://www.metabunk.org/sitrec/?sitch=video The goal here was to create a quick video player for zooming in on sections of video, going frame by frame, and (optionally) showing the original pixels. It only works in Chrome, Edge, or Opera (Due to reliance on WebCodecs) Should work with most...
