Gosh darn it! What type of graphics card/system do you have?

mine lasted 50 secs. was a bit laggy, the dot paused for a millisecond every now and then..but i have an online game on one tab and youtube playing on another. i also havent rebooted or cleaned my computer in a while.

on windows, edge browser. 8gb ram, no idea about a graphics card but a pretty cheap laptop so probably not top of the line.

this?

It seems like the issue is my video rendering code. I've been decompressing the entire video into individual frames, just because it was easy. But that seems to be causing memory problems. I'll have to rejig it to only cache a few frames, but that's going to be complicated.

It wasn't causing me problems, seemingly because of Apple's M1 magic.

I have 16GB, Aguadilla also crashes after few secs as well

Can you try it now? I've rewritten the video playback code to only cache frames near the playhead and some key frames for high-speed scrubbing. Reduced Chrome GPU memory usage from 10GB to ~2GB

Seems to work fine now for me. Thanks!

Thanks. It's not perfect, so there are occasional glitches, but I should iron those out eventually.

And they should be iironed out now. Let me know if something goes wrong

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.

Also in Agua, improved the smoothing of the camera track by using multiple iterations of a narrower window rolling average.

I did a pretty major restructuring of the rendering pipeline over the last few days, just uploaded.
This should mostly be invisible. Better resolution on some displays.
The main change is to allow post-processing effects, to make the simulated view more like the original video. So far I've just done a vaguely FLIR-like pass (invert and reduce red and blue, boost greenish colors) to Aguadilla:

This can be toggled:

This seems to work on everything I've tried it on, but if you notice anything, then let me know, thanks.

- and hopefully make it available so others can use it on arbitrary videos. You can see (and use) it here:

Hey Mick,
Any further news on this, such as how far along development is? I'm very interested in Sitrec getting to a stage where it can be used for any arbitrary video/scene

Do you have a rough time frame on releasing it (hopefully to a Github repo) so others can tinker and possibly help with development?

I've been a bunch of refactoring and adding things. But it's on and off. Probably going to be a while.

Minor fun update. Double clicking on any window will make it full screen. A quick method of removing the clutter.
