Hi,
Have you tried what is outlined in this article : http://www.ptgrey.com/support/kb/index. … &q=310
If you have a 64bit system it may very well be the issue, as Kinovea is a 32bit application.

Re: tennis de table_analyse de la répartition des points d'impact (8 replies, posted in Français)
Ha, ça tombe bien que tu remontes ce sujet car il y a du nouveau dans la version à venir 0.8.23.
Deux nouvelles fenêtres d'analyse de données sont disponibles, une pour l'analyse de trajectoires et l'autre pour l'analyse de nuages de points, pour répondre au besoin exprimé dans ce topic. (en attendant une troisième pour les angles, mais plus tard).
On arrive sur la fenêtre en faisant "clic droit > Analyse de données" sur un des points ajouté (outil « marqueur »).
J'ai repris la vidéo de l'échange de tennis de l'exemple précédent, ça donne ça :
Le rectangle bleu pâle correspond au plan de perspective ayant servi à la calibration, ici c'est l'aire du terrain de tennis en lui-même (quatre coins bien visibles, dimensions connues). Les coordonnées brutes des points peuvent être exportées dans un fichier (format CSV) ou dans le presse-papier. Le graph en lui même peut également être exporté.

Hi,
I sent you a mail a few days ago to help test a pre-version. So, I would say the answer is in your hands :-) Let me know if you have changed e-mail.

Re: Keyboard shortcuts list? (2 replies, posted in General)
You can get to the list of shortcuts from menu Options > Preferences… > Keyboard.
However it is very much tied to the user interface, it would be quite contrived to pull it off this way.
What would be required is a more generic triggering mechanism to start and stop recording, with various "sources" for the trigger. Sources might be a keyboard shortcut, a timer firing, an audio threshold, a TCP packet, etc.

For the record I have just posted a question on User Experience stack exchange regarding polyline tools. The polyline tool will be the underlying tool for curved lines and arrows.

Re: Experimental version - 0.8.22 (10 replies, posted in General)
Hi,
I think both issues are addressed in the next version 0.8.23.
It has been ready for quite a while to be honest, I was waiting for more feedback.
The changes related to your comment:
- there is now an embedded plot window,
- the time values for it are in milliseconds so its always numeric,
- other values have three decimal places,
- you can export the graph or the raw data to a file or copy it to the clipboard.
- The data is exported as .csv for maximum compatibility.

Re: Improve tracking (2 replies, posted in Bug reports)
Hi,
Yes good markers will go a long way to improve tracking, especially in case of complex background.
If you are not using version 0.8.22 already then I suggest you try it because it lets you can change the size of the tracking windows (object window and search window).
For the marker design themselves, if size permits, you can use two concentric black and white rings, a bit like an archery target only with black and white stripes. The ring shape is to make them invariant to rotation.
If the video is already on YouTube you can add it like this for example:

Topic: Fixed "Angle to horizontal" tool (for 0.8.21, 0.8.22) (0 replies, posted in Bug reports)
A bug on the Angle to horizontal tool has been reported by samfuen (thanks !).
The bug affects versions 0.8.21 and 0.8.22, possibly older versions.
A corrected version of the tool is available here : 8 - Angle to horizontal.xml
Fixing your Kinovea is simple, download the file and replace the old one in the installation directory, sub directory DrawingTools.
For instance: C:\Program Files\Kinovea\DrawingTools\ or C:\Program Files (x86)\Kinovea\DrawingTools\ for 64bit systems.

Hello, I have a problem in kinovea 08.21, because horizontal angle not working. What I should do?. Thanks
Hello,
I assume you are referring to the "Angle to Horizontal" tool. I reproduce a problem where moving the central point causes the drawing to disappear (reference line collapse to a single point). Is it the problem you are experiencing as well ?
Strangely enough the Angle to Vertical tool is not affected. I'll see where the problem is.

Re: Tablet Dell Venue 8 Pro : See only an image section (6 replies, posted in Cameras and hardware)
It seems the issue may come from the tablet (camera drivers probably).
I found this topic "Dell Venue 8 Pro Camera Resolution changes during video chat" on the Dell forums which despite the title seems to describe your issue.
Also:
Dell Venue 8 Pro: Front camera using Skype or Google Hangouts is super zoomed in
The issue apparently is with desktop apps, not Metro apps. Other posts report color mangling with Google Hangouts.
By the way, do you reproduce the issue with the back camera ?

Re: Tablet Dell Venue 8 Pro : See only an image section (6 replies, posted in Cameras and hardware)
What version of Kinovea are you using? In recent versions you should be able to tap and drag the picture around and double tap to cycle between fitting the screen and 1x zoom.
Does the picture fill the capture screen but is so large that you cannot see the sides? Or is it that the picture is displayed inside a small rectangle within the capture screen?
On the desktop CTRL+Mouse wheel is bound to zooming. I don't know if the pinch gesture is emulating this or sending its own commands.
I cannot test for touch screens at the moment, I'll see if I can find an emulator somehow.

Try to double tap the image to make it fit the screen.

Re: Logitech C920 - Cameras speed (fps) unstable when using two webcams (27 replies, posted in Cameras and hardware)
As an experiment you can also test the camera simulator (just added in 0.8.22). From the Camera tab, click on "Manual connection" button. In the "Type of camera" combo, choose "Camera simulator" and click "Create camera". Create two of them and go into dual camera mode.
From their configuration you can set them to HD 720 @ 30fps for example, and see if the framerate stays stable, with and without recording.
