Hi, check the feature called Replay folder observers:
https://www.kinovea.org/help/en/capture/replay.html

The way it works in Kinovea is that you point the player to a directory instead of a file, and it will monitor that directory and automatically load and play any new file created in that directory. So you can point it to where the capture instance is saving the files and it should create such a capture-playback feedback loop. For two-camera system you'll need to configure the capture to save into different folders so each player loads the matching one.

Another way if don't care about archiving each swing is to use the delay feature. If you set it to 5 seconds or so, you can just look at the capture screen for an instant live replay.

Hi,
I need to re-test this on various players on modern Windows. VLC media player should work. I'm not sure why Windows Media Player doesn't work.

I'm not sure what you mean here. Kinovea will export to AVI, MKV or MP4, using MJPEG codec. If the resulting video tries to opens with Windows Media Player it's most likely because it's the program associated with the chosen extension. Most probably the target player doesn't support the format or codec. I'm pretty sure Windows Media Player doesn't support MKV unless you install third party support.

Please send a sample video by link here or privately by email, thanks.

Hi, it works out of the box on a Windows 11 PC with an Intel or AMD x64 processor.

I'm assuming you have a new Mac with an Apple M1 ARM processor so parallels will run Windows for ARM and then there is a second layer of emulation to run Windows x64 programs like Kinovea. I don't have a Mac computer and I can't test any of this. So far no one has been able to make it work as far as I know.

Hi,

Right now there is no way to get this from the user interface.

If the calibration is static (the grid is not moving), then the corners of the grid can be found in the KVA file in the "Calibration" block. This has the coordinates of the grid quadrilateral in image space in pixels. The vertices are named ABCD starting at the corner in the top-left (for the default grid placement) and going clockwise. In other words the direction vectors are always X-axis: DC, Y-axis: DA.

For a moving calibration it's more complicated. I should probably just allow pixels as a "metric" in the units selector. I'll check if that works without side effects.

You mean the version of .NET on Windows server 2016? Kinovea uses .NET 4.8, you do need to install it manually I think on this OS but if that was the problem I think it wouldn't run at all. The part causing the problem (ExpTreeLib) has all kinds of low level calls into the very old Windows API, that's why I think it's more likely the culprit.

Hi,
There are two different time tools, the Stopwatch (Cronómetro) and the Clock (Reloj). The clock object only shows a relative time and doesn't have start/stop commands. Somehow you are using a clock object.

If you right click on the tool in the tool bar you should see both objects.

It's also possible to convert one to the other by going into right click > Configuration and checking or unchecking "Clock".

Lastly, if it always act as a clock even when you select the stopwatch tool, double check the default options by going into the "Color profile" (last button on the toolbar or right click with the tool active), find the stopwatch and make sure it has the "Clock" option unchecked.

Hi,
I did not quite understand what you meant.
In any cases all options are under right click. To improve tracking you might need to reduce the default search and object box sizes in the preferences.
