That's very odd and the first time I hear about something like this, I'm not sure what could cause the issue.

If you go to the log folder there might be a number of crash files with names starting with "Unhandled Crash", could you please send me the log.txt and log.txt.1 and any of those Unhandled crash files at joan at kinovea dot org please?

Are you working with two instances of Kinovea or dual screen inside one instance?
Do you have the same issue when working with just one video? Is it specific to when you work with two videos?

Normally when it crashes the next time you open it should propose to load the last session, including any unsaved changes, if you don't see that there might be a second problem.

So it picks up voice correctly but not the ball impact, at roughly the same volume? I'm not sure but maybe there is some sort of clipping of high frequencies or maybe it's even a feature of the microphone to remove high pitched "clicks" which are normally undesirable in voice communication? See if there is any sort of "helpful" noise filtering that you could disable.

Hi, these instructions are for an older version, there is an additional "arming" mechanism now that's preventing unwanted recordings, and it's disarmed by default (this may change in the future but for now it's like this). In the toolbar at the bottom of the screen there is a speaker icon that you need to toggle. Once you toggle it to "armed" it should work. You need to do this once at the beginning of the session.

You can start with this:
- Stream format = "Mono" or "Mono8"
- Exposition = 4405 µs or lower. (1000000 / 227)

Also for Daheng apparently sometimes the camera has a default bit depth at 10 bits which limits the max frame rate, for this you need to go in the Galaxy Viewer and change the setting for "SensorBitDepth" to "Bpp8".

I didn't quite get the relation between triple playback and HD framing.

It should be possible to add spacing between the two videos, or maybe a margin at the bottom, I'll write it down for later.

The plugins tend to be specific in the version of Kinovea they work with, for now. If you are using version 2024.1 I would suggest to use the GenICam plugin: https://www.kinovea.org/en/forum/viewtopic.php?id=2005

It is unlikely to happen in the near future. Other things you can do is launch two instances of Kinovea, but you won't have synchronization, or maybe synchronize two videos first, export that and then load the combo with the third.

May I ask if this is for synchronizing 3 different persons or 3 different views of the same person, or something else?

Very cool. Reading your original post I thought this was like a contact microphone but in your case it can just hang on a net and get triggered by distant movement, quite interesting.

How sensitive is it? If we put it on a high jump mat for example, would it trigger from the jumper falling on the other side of the mat? Or if it is attached to a net like in your picture and someone else passes by quickly, does it trigger from the small wind?
Maybe it could also be used to detect water surface breaking in diving.

Actually this makes me think there could be a function where the trigger is used to increment a counter instead of starting capture.

This sounds great! The link doesn't work maybe the repository is on private?

If you are not using the center of gravity point then it doesn't really matter, you can place the joint points exactly where you need them to be according to your needs. The CoG placement is based on segment weights coming from old anthropometric tables. You can build an alternate human model by modifying the existing one if you need more customization.

Hi, there should be one or more files in the log folder with names that start with "Unhandled exception", could you paste the content of the most recent one here as well? This will contain more precise information for debugging.

But more importantly this is from an old version published in 2011, could you try and see if you reproduce the problem in the latest version? A lot has changed in the comparison/synchronization system.

It appears the issue with FLIR cameras is that when you have two of them of the same model connected at the same time, the identifier we use doesn't differentiate between them and this causes a crash. Single camera should work.

Hi,
What version of Kinovea are you using? There were some important changes in 2024.1, it's possible there is a regression I haven't noticed in my testing.
Is the camera static? Are you using camera motion estimation? When you say a digitized point do you mean a new static marker or a new point along a trajectory?
Indeed a given point on a given frame shouldn't change coordinates unless the coordinate system is tracked or the calibration object is tracked, is it your case?

That's great to hear!

Yes the Spinnaker SDK has the "FLIR_GenTL_v140.cti" file which is a bridge between the actual device driver and the GenICam libraries. (In the case of user aroe79 above they already had that installed based on the log so that wasn't the issue).

I'll add a little paragraph to the first post to clarify.

En el menu Herramientas > Calibración del tiempo (puede que sea otro nombre según la version de Kinovea). En este dialogo se puede cambiar el eje del tiempo. Si quieres que el video se reproduzca a 120 fps, ignorando el valor escrito en el archivo, puedes cambiar en la parte inferior.
