Hi Joan,

I remember your working on a capture option within Kinovea. Maybey its possible to make it so that you can capture 2 devices at the same time (like Dartfish). Nou in Kinovea you can compare two movies. (We make movies from behind en below of the foot).

Greetings.

The Capture screen will make its debut in the next experimental version (0.8.9). It will be relatively simple feature-wise, as I'd like to have it integrated now, and then add missing features based on feedback, instead of trying to do everything in the dark.

You'll be able to have 2 capture screens at once, (or 1 capture screen and one player screen), I haven't tested simultaneous recording yet tongue

Yes, the main thread is [Capture] - How should it work ?.
I think we should follow the discussion there, I'll copy the end of the message there.

Well yes, this has been raised in the past aswell… It has went from arrow, cross, hand, and finally the semi-transparent hand with the little cross in the middle to help targetting.
The center of the little cross is the actual pixel position of the pointer.

I guess this would mean an option in the preferences pages. I'll add it to the suggestion list. It may be added later when there are other modifications needed to the preferences pages.

Par contre je rencontre le même regret du coup que l'utilisateur plus haut: à l'export en tableau on a le nombre d'image mais pas le temps ce qui est très regrettable quand on souhaite tracer des graphiques: par exemple l'évolution de la position ou de la vitesse en fonction du temps!

Bonjour,
On peut avoir du temps, mais quand on choisi le format « 0:00:00:000 » c'est du texte.
Quand on passe en nombre d'images, c'est également des temps finalement. L'unité correspond à l'intervalle entre les images.

Il y a également les autres formats numériques comme « centième de minute » qui peuvent permettre de faire une courbe d'évolution.

Sinon, il est également envisageable d'avoir un format qui reprendrait le total des secondes (ou le total des millisecondes). Cela devrait être assez simple à ajouter je pense.

If possible please do the following :
1. Open Kinovea, then open the logs folder by menu Help > Open log folder…
2. Get to the point where you think the crash is imminent, save the .KVA file somewhere.
3. Provoque the crash.
4. Without restarting Kinovea, go to the logs folder you opened in 1. Copy the file "log.txt" and "Unhandled Crash - XXX.txt" somewhere else.
(you may have several Unhandled crash files, the most recent should be sufficient, you can delete the others).

Attach the .Kva and all log files to the bug issue, or send them by mail (joan at kinovea dot org).
Thanks.

Hi,
Yes, issues have been reported with AVCHD files and hi-res videos.
What you may try until the performances issues are being investigated and worked on, is to restrict the working zone to as little time as possible. The goal would be to trigger the Analysis mode, where the images will be cached to RAM. This way the decoding time will be nil, which should increase performances.

Well, it really bugged me, so I went ahead and added some formatting options smile

Please welcome the new comment box:

Also, while I was at it, I tackled an old item of the todo-list : the ugly floating color picker.
The new color picker is very much inspired from the one you can find in Greenshot. Greenshot is an awesome open source screenshot application for Windows.
The new picker has more colors, and a list of recently used ones.

This will be up in 0.8.9, feedback welcome big_smile

While testing for the bug m208 (Crash after about 60 comments – that I can't repro right now), it occurred to me that the comment box is really really basic.

A title line + an area to input unformatted text… You can hardly make it more minimal.

Bold, italic, underline, highlight color ? These seem pretty standard on every text box around, even on web pages.

Thoughts ?

In the french section of the forum, someone seems to be using it a lot in Tennis.
I'm not sure exactly how though.

The coordinate system menu and dialog is currently only used to set the right coordinates of points when exporting to spreadsheet formats or text.

There is also a subproject to add a more convenient measuring interface.
It is described in the coordinate axis wiki page.
(Will be started when/if sufficient interest is expressed)

Someone has expressed interest in this function by mail.
The idea is still to minimize the number of menus to simplify the interface, so before reinstating this more feedback will be needed.
(Ah, if someone wants to implement a plug-in system for these video filters it would solve the problem smile)

For those new to Kinovea or that never tried it before and can't now since the menu has disappeared, here is a snapshot:

Right: Normal video, Left: Through "Edges Only" menu.

I have just addressed this. Now the sub directories structure under "guides" will be mapped to menus and sub menus (unless a given directory doesn't have any .svg file).
I don't know if Kinovea will have several directories by default, but the possibility is there for the user as a start.

Yes you're right, good idea smile
It will allow the user to better organize by grouping related shapes together.
Sharing several shapes will also be more convenient if you can group them under a single folder and just copy that folder.

Hi,
I have programmatically created a file with 100 key images with 20 lines of comments each. Although it takes a few seconds to load, I couldn't make the application crash when manipulating the comments. There is probably some context I am missing to properly reproduce the issue.

What is the behavior ? does Kinovea become unresponsive and you have to kill it manually, does it crashes with an error dialog from Windows ?
In the latter case, can you try to get the applications logs and attach them to the bug tracker or send them by mail.

Thank you


edit: Oh, to be sure, you are talking about Key images comments, not text labels right ? (From the little comments window with the key image title).

Ok, je vois mieux. Dans ce cas je pense que ce sera effectivement plus approprié en tant que « Référence d'observation ».
Par exemple sur la capture d'écran au dessus, on voit qu'il y a un objet existant (en rouge, centré sur le genou) qui pourrait déjà servir. (il a juste les graduations en degrés, pas en heures).

Avis à tous les utilisateurs, à propos des références d'observation (accessible depuis le menu Image -> Références d'observation) :
Même si la fonction en est encore à ses premiers stades, je pense qu'elle a un fort potentiel. Elle permet d'utiliser des dessins de complexité arbitraire sur la vidéo, justement pour ce type d'usages.

C'est une fonction qui tente au maximum d'être ouverte et extensible (fort taux de bidouillabilité smile):
- Elle est basée sur le standard SVG. On peut donc créer ses formes géométriques à l'aide d'éditeurs SVG populaires comme Inkscape (logiciel libre).
- Extensible : il suffit de placer le ficher .svg dans le dossier « guides » de Kinovea (dans Program Files) et la forme géométrique sera automatiquement listée dans le menu au prochain démarrage du programme.

Il est possible de modifier les fichiers existant pour les adapter à ses besoins.
La collection de fichiers fournie avec la version 0.8.8 est un peu limitée, (rapporteur, squelette, etc.) mais plus il y aura de retours sur cette fonctionnalité, plus la collection s'agrandira.

Chaque utilisateur peut suggérer de nouvelles formes à créer, en créer lui même, adapter les formes existantes à son sport, etc.

Si cela fonctionne bien, j'ouvrirai une section spéciale sur le site où chacun pourra contribuer et ajouter ses créations, profiter du travail des autres utilisateurs, récupérer leurs fichiers pour les modifier et les adapter à d'autres sports, etc.

Pour l'instant pour lancer la machine :
- Donnez des retours d'expérience sur la fonction. Comment l'améliorer ? (je pense qu'il y a des problèmes au niveau de la manipulation… autres ?)
- Suggerez des nouvelles formes ou commencez à en créer (par exemple avec Inkscape).

Merci smile

Thanks for the report. I'll look into it as soon as possible.
