Effectivement il semble qu'il y ait un bug quand on étalonne avec une mesure contenant une virgule (type « 25,5 » cm). sad

En attendant utilisez le point « . » comme séparateur décimal…

Another thing I would like (as a user) is floating thumbnails when hovering the mouse on the list of files.
This way I wouldn't have to close the current screen in order to check the thumbnails to select the next file.

Vous pouvez essayer la fonction "Vue d'ensemble" du menu "Mouvement".
Pour l'utiliser vous devez au préalable réduire la zone de travail jusqu'à déclencher l'extraction des images en mémoire.

Bonjour,
Vous auriez un exemple ou une photo d'écran ? Je ne comprends pas très bien le problème…

Certains logiciels ont une fonction de désentrelacement qui recrée une image complète à partir de chaque demi-image (lignes paires ou lignes impaires) fournie par la source. Je pense que c'est de ce type de fonction dont vous parlez ?

Pour l'instant le désentrelacement dans Kinovea ne fonctionne pas comme ça et recréé l'image à partir des deux trames existantes plus ou moins en les combinant dans le résultat. On reste donc sur la fréquence image d'origine de la vidéo.

Peut-être dans une future version en fonction des capacités de la librairie de décodage de fichiers.

Quel type de tablette numérique ?
Attention Kinovea nécessite Windows et la plateforme .NET 2.0. Le programme n'est donc pas compatible avec les tablettes de type iPad, Android, etc.

You can also use the Tracking feature.

Right click the object and choose "Track this point". You can then move frame by frame and manually set the position of the target by dragging it where you want. (the "automation" is just a help, it tries to find the point automatically but the feature was designed to retain full manual control any time)

For each trajectory created this way, you can right click + configure and set a "label" to differentiate it from the other. This will show up later when you export to spreadsheet (menu File > Export to spreadsheet).

I don't know how you/they can be trained, you can help me. thanks

- Export to spreadsheet will only be enabled when you have added drawings, stopwatches or trajectory to the video.
- Common controls and invert position will only be enabled when there are two player screens.
- Image adjustment menus and menus under Motion will only be enabled when you are in "analysis mode" (frames preextracted to memory). Check this page "Observing motion" (here for Italiano)

Kinovea compatible with ANDROID to be abble to use it on E- Tablette?

Hi yvesrpt, It's a good question you asked. Kinovea requires a substantial amount of CPU processing to perform its tasks (especially if you dual record). I doubt tablets at this stage would have enough processing power to achieve this.

When I worked on Android (at work) it was all done in Java and we had a limit of 16MB (possibly 24MB depending on devices) per application.
Kinovea can only be ported to platform supporting .NET and with support for C# and C++/CLI languages (currently only .NET for Windows can do this, Mono cannot do C++/CLI).

The Linux / Mono port would have precedence over anything else anyway, but even that is pretty hard due to some dependencies on Windows (and the C++/CLI part).
Personally I am more inclined to work on improving the Windows version. There is a million things to keep me busy already.

I think there are efforts by others to develop video analysis applications on Android.

Hi,
Yes there are some known issues with the MTS files. You may need to restrict the working zone until it triggers the "analysis mode" (pre-extraction of frames into memory). Depending on image size / frame rate, this can be as low as 2.5 seconds.

Generally speaking, the difference between forward and backward frame by frame comes from the way the images are encoded inside the file. Some codecs use intra frame coding only (each image is compressed separately from the others) others use inter frame compression, which means for us that a given image can only be reconstructed after we also decompress another image. When we go backward, we actually need to go back a few frames first (back to the last full frame), and then decode all the frames inbetween.

There is also issues with some containers that do not index the images (VOB), or index them in a bizarre way (MTS).

Bottom line is :
- Some files are more suited to going backwards in the same ammount of time than forward.
- To even out the differences you can restrict the working zone to trigger the pre extraction of frames into memory.
- You can convert the files to a more suitable format using such tools as AviDemux or HandBrake.

Ha ! I had forgotten about that one smile
Well I don't know where to find a side view but if you can find one in SVG or other image format, you may import it.
I did find a bunch of anatomy files here and there (Wikimedia Commons), but there is no side view skeleton.

Great !
Yes, some stuff has been done regarding memory in the saving routine. Initially to work around an issue for capture with large image size, but it should help with dual screen saving and regular save as well.
