Let's continue the discussion on github here: https://github.com/Kinovea/Kinovea/issues/121

La primera cosa es que solo funciona con las cámaras de tipo Machine Vision porque otras cámaras no tienen el nivel de control suficiente.

Si tienes una cámara de este tipo, puedes experimentar con reducir la resolución vertical, hasta que sea bajo de 16 pixeles (por ejemplo: 1024 × 4 px). Aconsejo ponerlo en lo mínimo posible. A partir de este momento, entrara en el modo escondido/experimental de finish line / photo-finish. En lugar de mostrar las imágenes individualmente, colocara las nuevas "bandas" bajo de las precedentes, continuamente. Con esa baja resolución, puedes aumentar la frecuencia de imágenes hasta 1000 o 2000 fps o más, según la cámara.

Nota: es solo activado bajando la resolución vertical, porque esas cámaras funcionan así. Bajar la resolución horizontal no permite aumentar la frecuencia, el sensor lee linea por linea de todas maneras. Hay que disminuir el numero de lineas. Entonces en la practica deberás poner la cámara físicamente tumbada al 90°, para que el efecto photo-finish sea el correcto.

En el fichero XML de preferencias, encontrarás un nodo `PhotofinishConfiguration`. Por el momento es el único modo de cambiar la configuración.

<PhotofinishConfiguration>
      <ThresholdHeight>16</ThresholdHeight>
      <ConsolidationHeight>2</ConsolidationHeight>
      <OutputHeight>1000</OutputHeight>
      <Waterfall>true</Waterfall>
      <WaterfallFlushHeight>100</WaterfallFlushHeight>
</PhotofinishConfiguration>

No sé exactamente si será útil para el salto de longitud pero sería interesante que más personas experimentaran con esto.

Verifying account creation isn't sustainable, it's what I did for several years but now there is just too much volume. I just double checked the numbers, for the month of July alone I got 982 registration mail alerts. I'm not reading them. These are only the ones that manage to pass the captcha. About half of them go to a special honey pot page I set up but the rest is still too much. So we need to wait until they make their first move and reveal themselves.

The frustrating part is that the bots continue to attack even if it doesn't work. The website must be in spammers database somewhere and they just don't care if their attempts fail.

Some of the bots are also never posting but use the report button on random posts and put a link in the "reason" field, that doesn't make any sense, only a forum admin/mod can read this… I hope they don't start to do this more often.

Not directly at the moment. The closest thing is to use OpenPose to generate .json pose files, then you can open the first one in the folder as an annotation file. It's not going to create trajectories though, each pose file is converted to a separate posture drawing on the corresponding frame.

Yes unfortunately I haven't had time to fix this and update to newer Pylon versions.

When you add a line it is attached to the particular frame you added it on. Let's call this the anchor frame.
- Select the "Custom fading" option for the line.
- If you don't want to see the line before the anchor frame at all, set the Fading duration to zero.
- If you want the line to stay fully visible for say 10 frames after the anchor frame, set Opaque duration to 10.

More details:
"Opaque duration" is how many frames after the anchor frame it will stay fully visible (or at the max opacity configured).
"Fading duration" is the fading in/out effect that is created before the anchor frame and after the last frame of the "opaque period".

Each object can have its own fading/opacity parameters, by using the "Custom fading" option. If it is set to "Default fading" it will use the global option configured in Preferences > Drawings > Opacity.

If the line is tracked it will be forced at max opacity while it is tracked.

Glad you solved your issue. You were talking about passing WM_COPYDATA messages right?
I actually tested this outside of C# so if you could share the final code snippet where you make the call it would be great, I'll add it to the documentation somewhere. I think it would be great to have several code samples in various programming languages for this.
