The location from an observal reference in the preview is not the same with the location from the captured movie.

Currently we can't find out if the captured stream has rectangular pixels. (image format 4:3, 16:9, if different than the resolution).
Can you try to determine if this location problem is linked to this issue ?
Is it the same with other drawings or just the observational refs ?

Where is the capture option?

It is available in the latest experimental version (0.8.9)

Because of the start/stop nature of many sports (American Football) one needs a capture routine that automatically creates a new file every time the recording is stopped.  Each new file should be named such that an alphabetical sort will keep them in the order recorded.

Yes, it was designed like that smile
Basically, it looks for a number in the entered file name and increase that number to suggest the next file name. Hopefully you just have to hit rec/stop.
For exemple, if you set filename to "attempt 5", the next will be created as "attempt 6". (You can still manually change it if needed).
- If several numbers are found, only the last one is incremented.
- If none are found, a "- 2" is appended ("attempt" -> "attempt - 2" -> "attempt - 3", etc.).
Same applies for the image snapshot file.

Does the file play back in Kinovea at all ?
If not, there's probably an issue with the saving. What version are you using by the way ?

Hi,
"Error -2010" : Which player is giving this error ? Is it also Windows Media Player ?

Here is how various players should behave with videos created in Kinovea :

- VLC : should work out of the box.
- SMPlayer : should work out of the box.
- Media Player Classic : You will need to install a codec for MPEG4 ASP (for example Xvid).
- Windows Media Player :
1. You will need to install a codec for MPEG4 ASP (for example Xvid).
2. If using MKV container, you will also need to install the appropriate demuxer (for exemple, Haali Media Splitter)

It is also possible that the save failed and the file is corrupted somehow. Do you get the same error over and from different attempts, even with the codec installed or in VLC or SMPlayer ?
Can the file be read back in Kinovea ?

Thanks.
Regarding the flickering, I think I have an idea of where that could come from. The frame buffer is very basic right now and needs to be made more robust.

TeamTermin wrote:

I would recommend that if a connection gets lost (and many times it does because the camcorder goes into sleep mode because when you are capturing live directly into the computer, you wouldn't necessarily need to also be capturing to tape) that the software saves the previous device connected, and will either re-connect automatically if it's the same device, or it will show back up in the menu.

Ah yes.
Probably it should be constantly monitoring the connection, raise an indicator when it's down, and simply resume frame grabbing when it's back up.
I would assume the connection cut would stop any ongoing recording operation…

TeamTermin wrote:

I would also suggest for live capture mode, possibly a drop down box, of different popular encoding profiles to choose from.

Yeah, currently the file will default to .mkv, and to change to .avi or .mp4 you have to explicitely add the extension in the file name edit box.
I agree, that is not obvious at all, and it's impossible to know which formats are actually supported.

I'll add a combo box to pick output container format.
However the actual codec used and parameters, which is ultimately what impacts file size and image quality, will still be non-modifiable for a while. Because that will involve a more complex interaction schema on user interface and on encoding library ends. I'm not sure I want to deal with the complexities of encoding / transcoding right now.

So by default Kinovea will output large files with (hopefully) good image quality (under the MPEG4-ASP codec). And the file size reduction will be left as a post process step for the user.
(By the way, there's a new kid in town for easy video conversion - Miro Converter - free and open source).

Version expérimentale : elle a besoin de vos retour d'expérience pour s'améliorer !

L'installeur est dispo ici :  Kinovea.Setup.0.8.9.exe

Pas mal de trucs intéressants selon moi dans cette version, les plus importants étant :

Dual Export
En mode "Deux écrans de lecture", vous pouvez exporter une capture d'écran combinée ou une vidéo combinée (respectant la synchronisation), c'est-à-dire côte à côte.
Utilisez les boutons d'export en bas à droite.

Écran de capture
Cela faisait un moment qu'il était en phase d'incubation, il est maintenant temps qu'il fasse ses débuts…
Il est loin d'être complet d'un point de vue fonctionnel, mais c'est fait exprès. Ce sont vos retours qui guideront les additions / améliorations tongue

Ce qu'il devrait être possible de faire : capture d'image, enregistrement de vidéos, dessins sur l'écran (y compris les grilles et les références d'observations).
Ce qu'il n'est pas encore possible de faire : Délai sur le direct, navigation dans l'historique récemment capturé.

Uniquement testé avec un camescope DV basique et une webcam à moitié cassée, donc merci de remonter les échecs et réussites ici.

Texte enrichi dans les commentaires
Gras, italique, couleur de fond, etc. voir capture d'écran dessous.

Des icônes partout dans les menus
La plupart des icônes proviennent du pack libre Silk de famfamfam ou en ont été dérivées.

Également correctifs des bugs suivants : m207, m210.

Capture d'écran : la nouvelle boîte de commentaires.

This is an experimental version : it needs your feedback to improve itself.

The installer is available here: [s]Kinovea.Setup.0.8.9.exe[/s] Kinovea.0.8.10 thread is up.

I think there is many exciting stuff in this release, the most important being :

Dual Export
When in "Two Players" view, you can export combined snapshots and combined videos (synchronized). Use the export buttons on the lower right.
Now go post them on YouTube big_smile

Capture screen
Incubating for a long time, it's time for the capture screen to make its debut.
It's far from feature complete, but this is on purpose. Your feedback will drive the additions / improvements tongue

What you should be able to do: snapshot, recording to file, drawings, (including grids and the new observational references).
What you can't do yet: delay live, browse recent frames.

Only tested with a basic DV camcorder and a half broken webcam. So please report success / failures here.
(for ideas and suggestions -> in this thread.)

Rich text in comments
Bold, Highlight color, etc. for the comments, as seen in this thread.

Icons all over the place in the menus
I feared it would be distracting, but in the end I think it's a nice improvement. Most icons are coming from the popular Silk set or were derived from them.

Fixed bugs : m207, m210.

Snapshot: the new comment box.

De la même manière quand on exporte sous format texte il y a un décalage des colonnes (à cause des dizaines) qui le rend un peu difficile à exploiter si on veux exporter dans un tableur moins "classique" ( Regressi par exemple... ).

Je ne suis pas trop sûr de comprendre le coup des colonnes… (?) Est-ce que cela concerne les formats numériques également ?
L'export texte est dans un format compatible sans modifications avec gnuplot, mais le but de cet export est justement de permettre l'utilisation dans d'autres logiciels…

Enfin bon c'était juste des petites remarques/suggestions je ne veux pas faire le lourd...

Pas du tout big_smile
Étant donné que je n'utilise pas moi-même toutes les fonctions constamment, il est assez difficile de savoir quand ça cloche, ou de découvrir les bugs subtils (ou pas).
Donc tout retour est constructif, dans le pire des cas la priorité de traitement n'est pas très élevée et c'est tout. Mais au moins il y a une trace.

Hi,
The option was missing from the routine reading back the preferences file.
Opened and closed bug m210.

Thanks for the bug report.

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.
