When I first try to export (without saving the key image data to the .kva file) I get zeros in the x and y coordinates

This was a different issue that had been overlooked and it has just been fixed in version 0.8.14.
Due to decimal separator differences (comma vs point) in languages the data with decimal part could be output as 0.
This impacted track coordinates, cross marker coordinates, and length of lines, for every language where the decimal separator is a point.
bug 241.

It looks like they have a Windows driver for the Kinect at codelaboratories.
Can you or someone with a Kinect try this in the experimental version and report the result ?
(I'm not too sure that it's a DirectShow driver ?)
Thanks

In the analysis tools department, it has been noted that the stopwatch is functional but simple.

Maybe there could be a separate cadence tool (or tempo tool). Something to simply assess the frequency of a repetitive phase. Like strokes in swimming, strides in track and field, rotations in discus or hammer throw, etc.
The usability of this will have to be top notch to keep things simple. (The lap function on a physical stopwatch can be confusing at first, the tool would have to be simpler than that if possible).

The next step is the ability to set the default thickness of the circle.

You would do that with the color profile. (last button on the drawing toolbar). Alternatively, you can also right click before setting the drawing. This will set the color and size for the drawing type as a whole.

Thanks for the clarification about the freehand arrow.

@Alexander: yep, auto-tracking magnifier and auto-tracking spotlight sound appetizing. Loosing the target will have to be handled differently than in the current tracking tool though.
Regarding improving the general video, if you refer to some sort of deshaking feature, I think this needs a different type of tracking (a "dense" tracking to compute the whole image motion at once). I'll eventually create a separate thread for this. That would probably end up being implemented as a "Motion" menu.

What i would find useful is a 'pencil' tool with an arrow.

Like drawing two big lines of the same thickness than the rest of the drawing ?

jon wrote:

Regarding the current circle tool. Would it be possible to customise the thickness of the circle?

You should be able to do this by changing the "size" parameter in context menu dialog or color profile window.

Écrire en Français dans cette section du forum svp ! tongue

Il est possible que le système n'autorise pas la modification des fichiers qui sont sous "Program Files" ou autres dossiers système. (Particulièrement sous Windows Vista avec un compte non-administrateur).
Si c'est le cas, il faut obligatoirement passer par un compte administrateur je pense. (À moins qu'il n'y ait une option quelque part pour permettre la modification des fichiers par les utilisateurs normaux)

Sinon il est toujours possible de charger le fichier à chaque utilisation en passant par le menu Image > Référence d'Observation > Importer une image.

J'ai créé une page pour lister les références d'observation ici : Dépôt RefObs.

Il semble que le rendu des images dans le navigateur ne fonctionne pas avec les anciennes versions d'Internet Explorer (avant la 9).  Dommage (surtout que IE9 n'est pas dispo pour Windows XP), mais je n'ai pas vraiment le temps de m'occupper de ça maintenant, surtout compte tenu du fait que cela fonctionne dans tous les autres navigateurs… hmm

(note: Il faut utiliser au moins la version 0.8.13 pour bien tirer parti de cette fonctionalité).

Pour l'instant vous pouvez m'envoyer vos contributions par mail si vous voulez.
Vous pouvez également poster vos suggestions de nouveaux fichiers dans ce sujet, si vous ne pouvez pas le créer vous même peut-être que quelqu'un d'autre le fera smile

I have set up a page to list observational references here : ObsRef Repository.

The rendering of the images in the browser might not work for some (all ?) versions of Internet Explorer. (It's a shame, I know, but I don't have the time to work out a solution right now, especially considering that it's working in every other browser I tried… hmm edit: works in IE9).

(note: you need to use at least version 0.8.13 to fully leverage the feature)

For the time being, you can send your contributions by mail if you want.
You can also post suggestions on new reference in this thread, if you cannot create it, maybe someone else will.

the clock tool, a circle with hours on it

This sounds like this could be implemented as an observational reference.
This reminds me that I wanted to craft some more "protractor" like tools there. (And possibly remove the few anatomy reference for now as they don't seem so useful as they stand).

also a multidots graphics

Can you expand a bit? I'm not sure I see what you mean.

daww wrote:

link the spotlight feature with the tracking feature

Yes, it would definitely be interesting to have that. I think similar idea has been suggested with the magnifier tool as well.
Maybe you would add a spotlight, and simply right-click it and choose a "Track this area" menu.
It would have to work slightly differently than the existing track tool though to simplify the usage.

(this is for mid-term evolution, please add your thoughts to the discussion smile)

I am not entirely satisfied with the existing set of drawing tools. Some important tools are missing, others could be improved in their functionality and usability.
I've been thinking for a while about what to do about it, with the goal of having the most comprehensive and useful set of tools possible. On the other hand, the interface must stay as simple as possible.

I like to think of drawing tools in two categories : tools to observe and tools to show. I also call them, respectively analysis tools and telestrator tools.
(Telestrators are devices used in TV broadcasts of team sports, to explain tactics to the audience)
Typically an arrow or a circle are tools to show the viewer where to look or what to look for. These are tools used during a debriefing, when creating a video explanation, or similar "teaching" actions.
The observation tools (measuring a line, checking an angle, stopwatch, etc.) are tools that would be used during the actual analysis of the performance.

Here are some of the intended changes :

Organisation
- Better organization of the tools on the toolbar to reflect the tool usage (just sorting them differently).
- Separation of the arrow tool from the line tool. Lines and arrows serve different purpose, the fact that they are implemented by the same underlying code shouldn't be reflected on the interface.

Possible new tools
1 - Spotlight : a tool that would dim the entire image except its own area.
2 - Rotation arrow : a tool to symbolize rotative motion.
3 - Auto numbering mark : a number inside a circle. Each time you add one, the number increments.
4 - Simple rectangle.
5 - Multi line - Should also support measure on each segment and/or angle value at each joint.

Improvements to existing tools
- Circle changed into ellipse ?

Considering the number of tools and the limited place some grouping of tools might be needed.

Mockups for some of the proposed new tools

Comments, ideas for new tools are much welcomed, as well as improvements suggestions on the functionality and usability of existing tools.

Bonjour,
La vitesse affichée est la vitesse moyenne du segment de trajectoire précédent le point. C'est à dire la distance du segment sur la durée entre les deux images.
La distance est la distance euclidienne classique : racine de [(xi - xj)² + (yi - yj)²] (où i et j seraient deux images consécutives).
L'intervalle de temps est calculé en fonction de la fréquence d'image de la vidéo.

Si x correspond a une vitesse dans votre formule, vous calculez la variation de la vitesse sur l'intervalle, donc plutôt une accélération ?

I agree 100% smile
Actually, there was once a "PDF export" function to export key images and comments  as a report, but it was later removed for various reasons.
Since then, I've added a more ambitious sub-project to the todo-list, to adress the shortcomings of the defunct PDF export function.
Ideally, it would be based on templates for maximum flexibility and easy customization, and the data be exported to something easily modifiable afterwards (like ODF).

There's a page on the developpement wiki about this sub-project here.
I don't find the time to fully get into this for now. It will later compete for priority with things like multi-point tracking, chronophotography and other effects, etc.
Also, lately I've come to think that this templates approach is maybe too complex/ambitious and a more straightforward (read: less flexible) approach should be preferred.

Existing reports done by hand would help in designing the feature though.
