Hi,
You are not missing anything, changing this option is not implemented for this tool at the moment.
That being said this tool is entirely defined in an XML file where this aspect is just an attribute so you could change it from there in the meantime.
In the program directory locate the DrawingTools > Custom > "8 - Angle to horizontal.xml" file and open it in a text editor.
In the Data section locate this:
<Angles>
<Angle origin="1" leg1="2" leg2="3" signed="true" ccw="true" supplementary="false" tenth="true"/>
</Angles>
You change the attribute `signed` to `false` to get the unsigned angle.
Do you see the red markers corresponding to the time origin in each video timeline and in the common timeline? (this is the synchronization frame in each video).
If the synchronize button does not work, does it work if you instead set the time origin independently in each video?
I think the ELP you have listed has a swappable lens with a standard mount right? You could use a wide angle lens or even fisheye lens on it.
In the capture screen it's only interfacing with the video output of the camera so it's only getting the video resolution, even if the camera can take still photographs at higher resolution.
Bonjour, il n'y a rien à faire, à l'heure actuelle il n'y a pas de son, désolé.
I would love to be able to set a point in the timeline and have Kinovea build up a cache of frames for a given amount of time before and after.
You can restrict the working zone around your set point in the timeline, this should trigger the caching, (if enough memory is allocated in the preferences).
Other than this mechanism, there is already a small cache constantly updated around the current spot, about 16 frames. Maybe there should be a visual indicator of this to give feedback about where it stops, and allow more control over its size.

Great idea. There is also a request for having a more prominent indicator that we are currently recording, so I'm thinking of having a label with the time since recording started would go in the same place in a corner of the viewport. Maybe there could be other info displayed there related to recording.
*I click my camera in the list (DAHENG IMAGING MER2-160-227U3M, IMX273, 1440x1080, 227fps)
Do you click from the list in the explorer panel on the left or from the thumbnail panel? Do you see the thumbnail at all? If you do F5 does it refresh the thumbnail?
Menu Image > Image rotation.
Have you installed another camera plugin since? There seems to be an incompatibility with the Baumer one where one of the plugin takes hold of some shared resource. Can you share the log of a startup, the camera initialization is logged, there should be some info there as to what's going on.
Not directly, no. You'd need to convert it to KVA XML to import it.
Hmmm, the original capture history panel was a tree with each day its own entry and the list of captured videos from that day below it. http://www.kinovea.org/screencaps/0.8.x … istory.png
But that was too complex to maintan. And you had to periodically clean it up, and always the problem of stale links when a video is deleted.
In what consist a "session" in your workflow? A day of recordings or just one event, so possibly multiple sessions per day? In that case it would need a concept of starting and ending a session, and the videos would be grouped under that session. More complex.
Another mechanism would be to use the Post recording command from automation panel, and point it to a script that collects all files in the current folder and consolidates them to a text file. The advantage of this is that once it's set up you can't forget to export the list. And you get the concept of session for free by just changing folder.
By the way are you trying to remove general shakiness of the video or is the tracked point independently moving?
Just to confirm, there is currently no image stabilization in Kinovea.
If it's for measurement purposes what you can do is track the origin of the coordinate system, this way the other points and lines will be measured with regards to that moving origin.
I made several experiments with regards to stabilization and moving shots over the years and to be honest it's mainly an issue of user interface and integration. I'm not really sure how to "present" this functionality in a well integrated way because it's modifying the video frames themselves and possibly the canvas size necessary to show them. Similarly you will note that there is lens distortion correction but the way it works is that it distorts the coordinate system instead of undistorting the images.
It does feel like a pre-processing step to everything else done in Kinovea and for now it has to be done in a separate app prior to loading.
Yes, please host it somewhere on a google drive or onedrive or similar and send me the link at joan at kinovea dot org.
Thanks.
