Ok, thanks.
I could find the issue and it should be fixed in next version.
The buffer holding the deinterlaced picture was never released 
However I discovered an new problem with some very specific videos and the new force aspect ratio function.
I'll try to re-air a version next week or so if I can fix this too.
Hi,
Thanks for the report.
Are you using the 0.7.10 version or one of the more recent experimental 0.8.x ?
Also, I think it might be related to a specific kind of .MOD files. Can you provide some more details about the origin of the files ?
(created m147 to track this)
Thanks
Hi,
There was an issue with the way the program was translating from the culture name ("en-US", "fr-CA", "pt-BR", etc.) to the internal representation of the language used for the interface, which is close to the neutral name ("en", "fr", "pt").
Norvegian is a special case ("nb-NO" -> "no", not "nb" 
) and the initialization failed.
The bottom line is that I found the issue and it should be corrected in next version.
I'm very grateful that you reported this because I think it was preventing virtually everyone with Norvegian locale to use the software ! 
This does not explain issues with the download however.
I'll look into the server's stats tomorow to see if I can detect something wrong.
Thank you, I'll investigate this. (and learning a few things about Bokmål along the way.)
Hopefully I can find the issue without installing a Norvegian system 
@tommped:
The \Roaming folder is a system folder, it is not created by Kinovea and should exist on your machine.
However it may be hidden.
I don't have a machine at hand to give you the exact steps, but you might need to change the options of the Windows Explorer so it displays hidden folders. See this article.
@RazeTiger:
Yes, the icon on desktop was removed at some point. If I remember correctly it was to follow some user experience guidelines from Microsoft. Maybe it should be reinstated.
Can you access the application data folder where the "unhandled crash" log live ?
I think that if the archive is corrupted somehow, it wouldn't install, so if it installed correctly, it should run unless there is another bug. In this case the "unhandled crash" log should have more data about it.
Hi,
Currently, no.
There is a "capture" feature in the works (although it's development is sort of paused for now) but it has not been designed to do what you describe, the focus was more on being able to browse the recent history of the stream.
The intended use was to let a performer review his performance just after it has been recorded.
To that end, the "key images" area was reused to list the individual records recently saved, and the drawing tools were made to draw persistently on the screen to act as reference frames during the action.
If I understand correctly, your usage would be more about recording a longer video, say a tennis match, and be able to create the analysis while the camcorder is streaming to the laptop.
I guess this falls under the "tools for longer videos" family and will probably require again a new screen type or at least a graft to the non-completed one.
I'm afraid to say that currently it's not a priority, but I'll add this to the suggestion list and I encourage any one to have a say about it here.
Also, maybe that is a suggestion that would interest the LongoMatch project as they are working on longer video analysis.
Thanks
Hi, please check the new pinned topic what to do in case of a crash and let me know if it's clear enough.
(The instructions are valid for 0.8.2 only.)
Basically from "Help > Open log folder"
edit:
Ok, obviously I haven't thought this through 
You will find it under the following location in XP:
C:\Documents and Settings\[your user name]\Application Data\Kinovea
And under Vista or 7:
C:\Users\[your user name]\AppData\Roaming\Kinovea
Reminder:
"Experimental" versions are available on the forum.
The goal of this is that you can test and comment on new features while they are being built.
So it's your turn to play now, and report bugs and usability suggestions .
The installer is available here: newer 0.8.3 available.
You will find the complete list of new features and improvements in the "readme.txt" in the installation folder.
Among other:
- Display mode for Paths (previously named Trajectories) where only a section is shown (for long paths).
- Option to force 16:9 or 4:3 image format if automatic detection fails.
- Some enhancements to the navigation when synchronizing.
Note: I couldn't test the installer on Win7 nor Vista, please report any issue.
Capture module development is currently on hold.
For general comments and suggestions : post in this thread.
For bugs, you can directly feed the bug tracker : http://www.kinovea.org/bugs
And here's a small snapshot :

Les versions « expérimentales » sont disponibles publiquement sur le forum.
Le but de la manœvre est que vous puissiez tester et commenter les nouveautés alors même qu'elles sont en cours de construction.
Donc à vous de jouer le jeu et de remonter les bugs trouvés et des suggestions d'ergonomie
L'installeur est disponible ici : Voir nouvelle version 0.8.3.
Vous trouverez la liste complète des nouveautés (et correctifs) dans le fichier readme.txt du dossier d'installation.
Entre autres:
- Mode d'affichage de trajectoire en section réduite (pour les longues trajectoires).
- Possibilité de forcer le format d'image 4:3 ou 16:9 si la détection automatique échoue.
- Améliorations au niveau de la navigation lors de la synchronisation de deux vidéos.
Note : je n'ai pas pu tester l'installation sous Windows 7 (ni Vista), merci de remonter tout problème.
Le développement du module de capture est pour l'instant en pause.
Commentaires généraux et suggestions : dans la suite de ce sujet.

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 ?
Salut,
C'est très étrange. Les boutons de lecture, pause, etc. sont visible à gauche mais pas ceux de droite ? 
Quelle est ta résolution d'écran ?
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.
Thanks for the report.
I have added code to log this type of exceptions in a separate file, so they are easier to debug.
As soon as the version 0.8.2 is out (should be next week), I would like you to install it and send me back this file.
I'll make a specific thread to better explain what to do in case of such crash to ease the debug process.
Hi, thanks for the feedback
Moving the cursor/markers with arrows instead of the mouse could increase accuracy in positioning.
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.
For future projects: using a visual "doppler" effect on estimating speed on a person approaching or moving away from the camera. The change in height/width of an object per time frame.
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…
Another thing: If I was interested in translating the program into Finnish or Swedish, how should I proceed?
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.
