The hand tool seems to struggle to select thinner lines and end points on all line/angle tools
This one should be taken care of in the next version. It was especially problematic with video of large size rendered on small screens.
Follow-up.
The bug is the following:
1. When a KVA file is opened and we click on "Coordinate System" menu, the default coordinate system is shown (center of screen) instead of the one specified in the file.
2. At that point if we export the file to spreadsheet, the coordinates exported are still expressed in the old coordinate system (from the file) although the centered system is shown on screen.
3. Exporting the file to KVA still exports the old coordinate system and values expressed in the old coordinate system.
These bugs affect 0.8.21 and were found to be already fixed in dev branch.
Thanks for the feedback!
1) Yes it is probably a rounding or truncating issue, I'll look into it.
2) There is a number of factors that can yield these type of issues, mostly the video codec being H.264.
There is a frame buffer that preemptively loads the next few frames and remember a few of the previous frames so you should always be able to go back a few frames. After that, it depends on the codec and there are some complications with H.264 with mangled time positions. I have to dig deeper.
3) To maximize the video you can also double click the image.
4) Yes, having the current used color highlighted on the color picker would improve usability a lot.
I didn't thought about having the persistence options available from there. I have to think about it.
Note that you can also switch default persistence globally from the general options.
5) Actually it works like this already for most of the tools, like lines, points or pencil. Circle should probably follow the same pattern.
I answered in the other thread. I think the best course of action is to make sure new versions understands the old format.
Normally I try to have conversion routines each time the format changes so that an older file can be incrementally upgraded to the newer format. If it doesn't work it's a bug that will need to be fixed.
Hi,
In 0.8.15 did you save the analysis in a separate KVA file or embedded in the video (the latter was a feature in previous versions that is no longer supported).
If you have it in a separate KVA, can you send it to me ? New versions should support the older format of "official" versions like 0.8.15, if it doesn't I'd like to study the problem.
Thanks.
Salut !

Hi gang!
Kinovea is now officially a non-profit organization, and everyone can join !
The organization is declared under French law for non-profits (Association 1901), everyone is welcome to join.
More details can be found on the dedicated page, in English or in French.
Please redirect general queries about the organization membership, donations, sponsorship, and other related matters to:
asso at kinovea.org.
Our goal is to catalyze Kinovea developments and more generally contribute to the ecosystem of open source tools for the analysis of movement in sport.
We hope to welcome you soon to be part of the adventure!
What versions are you referring to ? Older experimental versions ?
Currently the only supported versions are 0.8.15 and 0.8.21.
Hi,
The goniometer and all other custom tools' default color can be changed through the "Generic Posture" entry of the color profile manager.
At the moment this is not possible. You would have to decimate the data points in an external software.
I have started to work on improving tracking and measurement for the next version, and one area that I want to improve upon is the way the resulting data is presented and how it can be exported. Interpolation and decimation would be good candidates features for this.
In the next version plots of the measured data can be created directly in Kinovea, the problematic issue is mostly to design a good user interface to present the plot(s) and allow for flexible ways to export raw or filtered data.
Kinovea 0.8.15 does not run on my Windows 8.1.
It sticks on the opening splash screen and goes no further.
However, if you use the Compatibility Wizard on Windows and select Windows 7 , it runs fine.
It sounds like a .NET platform issue. Kinovea needs .NET 3.5, which is not enabled by default on Windows 8. Check this link for more details.
Hi,
Unfortunately I think what you want to do is not currently possible.
At the moment the command line interface can only open Kinovea in playback mode, not capture or mixed mode. It is definitely a weak point to be addressed.
Opening YouTube streams or anything directly from Internet is not possible. If they cache the videos as files on a shared drive on the local network and the machine running Kinovea can access it then it should pose no problem (although I haven't much tested playing videos from network locations).
Bonjour,
Le protocole utilisé pour le streaming des GoPro n'est pas implémenté dans Kinovea, donc pour l'instant ça ne peut pas fonctionner.
D'autre part notez bien que la résolution du flux vidéo est très réduite (en tout cas sur les tests que j'ai fait avec une GoPro Hero 2 + WiFi BacPac). Cela peut éventuellement servir à voir ce que voit la caméra pour ajuster son orientation, comme pour l'application pour smartphones, mais c'est tout. La qualité est dégradée par rapport à ce qui est enregistré sur la carte, les images sont très petites et très bruitées.
Il me semble que le logiciel VLC est capable de récupérer le flux si on met les bons paramètres.
Hi, thanks for the feedback!
1. Windows XP : note that the new version needs .NET 3.5. I think I forgot to mention it. Maybe that's the problem.
2. Magnifier: If I understand the need, it would mean to turn the magnifier into a regular drawing tool, that can have a persistence. I like this idea because currently it is a special tool and that means specific code in a few places which is not ideal.
3. Changing text: Interesting idea. Being able to keep 100% opacity between two key images would be interesting for all drawings actually, not just text, but at the moment I don't know how to have a simple user interface for this. The persistence dialog is already not very intuitive, I don't want to add complexity to it.
Having the text tool able to hold different texts depending on the time could be done too. But similarly, it must not add complexity to the existing text tool (basic tools must stay basic). So maybe a menu like "Multitext" that needs to be activated. When activated the persistence is switched to "always visible" and there are new menus to create and delete sections inside the text tool timeline. When you modify the text value, only the value of the section is impacted. Some sort of visualisation of the sections would be more user friendly.
After some thinking having persistence opaque between two key points would probably be the best option but both needs careful user interface design…
