Hello,

So, you record TV directly to DVD and then reopen the VOB file in Kinovea. Unfortunately, the duration of the movie seen by Kinovea is shorter than what you have recorded.

I have experienced this aswell with a commercial DVD, and someone opened bug m142 which I think is related.
I'll look into it further…

In the meantime, you can try to convert to another file format, I generally use HandBrake for this, but other converters should work. Output format might be AVI or MKV (for example in HandBrake, using the "film" preset), or others, if it can read all the input there shouldn't be any issue.
However this is a lenghty process so it's not a satisfying solution, I hope I can understand what the problem is.

Is it systematic or happens only sometimes ?
What if you record a very small sample of 2 or 3 seconds, does it work or not ?

Hi,
As I wrote in the bug tracker:
The program is not getting the Aspect Ratio information for any of the videos, so it assumes square pixels.
The HD video is 1280×720 which is indeed 16:9 in square pixels.
The SD video however is 720×576 (standard DV) which is 5:4 in square pixels and this is why it looks stretched.

Currently I don't have the time to track down the issue around the ffmpeg library, especially considering I'm not using the very latest version of the library (for a regression reason unrelated to this issue).

As a workaround, I have implemented a suggestion that was made earlier (I think it was Giorgio) to be able to manually force the aspect ratio.
So, in version 0.8.2 there will be a new menu under Image > Image Format with the following options : Auto Detection, Force 4:3, Force 16:9.
In a future revision I'll also add a "Default Image Format" in the General Preferences so the setting can be persistent between videos.

Hi, thanks for the feedback

Currently the arrows are already used to move the play head and the speed slider…
The only way I can think of mixing the two behaviors would be to have a sort of special mode that when enabled would change the arrow keys action… I don't know how this would be practical, will have to think about it.

(The "hand" cursor is a bit too big to be useful, this is on the todo list aswell.)

Another way would be to use the numbers on the numeric pad, but I think some have suggested to use them for hotkeys for named key image or as shortcuts for drawing tools.

Wow, this is ambitious
I don't know if we could do that in a reliable way though… If the person is not coming/going exactly straight away, it would be innacurate…

Please send me an e-mail : joan at kinovea dot org.
Currently the program is in a series of developpement iterations. Once it is stabilized, there will be a special localization iteration, where the languages should be added / updated.

Thanks.

Retirés de la liste car inclus dans la dernière version expérimentale. (0.8.1)
- Sauvegarde dans une vidéo avec arrêts prolongés sur les images clés.

Ajouté :
- [Lecture] - Pouvoir forcer le format de l'image à 16:9 ou 4:3.
- [trajectoires] - Un mode dans lequel seuls quelques points autour de l'image actuelle sont visibles.
- [trajectoires] - La possibilité de déterminer l'origine du repère utilisé lors de l'export de la trajectoire.
- [Images clés] - Pouvoir définir des événements sous formes d'images clés à titre prédéfinis, à insérer par raccourcis claviers.
- [Grilles] - Un encart permettant de voir l'aspect de la vidéo sous la grille de perspective en « vue du dessus ».
- [Synchronisation] - Un bouton pour ajouter une image clé dans les deux vidéos simultanément.
- [Synchronisation] - Un bouton pour vérouiller les outils en synchronisation. Les actions sur une vidéo sont reportées sur l'autre.
- [Images clés] - Voir les dessins, chronos, trajectoires, etc. dans les miniatures des images clés.
- [Lecture] - Mode plein écran avec uniquement les contrôles de lecture et de dessin.
- [Dessins] - Prendre en compte les différences de pression des stylets de tablettes graphiques.
- [Workspace] - Pouvoir minimiser les écrans sans les fermer.

They are just internal modes of working for the software. When the memory permits, the working zone selection is automatically switched into so-called analysis mode (for a lack of a better name) and all video frames are expanded to memory.
The browsing is faster and some functions under the "Image" menu become available.
The "normal" mode is used for longer videos that can't fit in memory.

That was "by-design" behavior actually.
If you have set a synchronisation point, the common controls are always relative to this sync point.
Maybe it's confusing and should be changed. I guess it shows that I wasn't sure about this sync lock issue.
This sort of confusing behavior would disappear if the sync lock is enforced.

So, what would be the way to enforce this "sync lock" while still being able to change the sync point ?
- a small button to lock/unlock the videos ?
- the locking would be the default behavior when a new sync point is choosen by the user ?
- to change the sync point the user would thus have to unlock synchronisation first.
- while locked, the individual controls on each videos are disabled entirely ?
- while locked, the individual controls are not disabled but using the ones on a video impacts the one on the other ?
- what happens when you change the working zone selection in one video, when you change the slow motion factor ?

Thanks guys for all the input and suggestions.
I've been quite busy with other stuff during the last month but I'll try to catch up

Hi,
This is strange… Would you be able to record two very small files (few seconds) in HD and SD and send them to me (joan at kinovea dot org).
I'll have a look at them and see if there is a defect in the source that I can fix.
thanks.
