I beg your pardon for this question, but: What's the difference between analysis mode and normal mode?

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.

I have to report another bug: after using the slider for the synchronized videos the common play-button doesn't start the vids from the new position where you stopped sliding.

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 ?

Hi,
Thanks for the report and suggestions !

I'll add the defects to the bug tracker. I've stumbled upon the second issue in the past (when only one video rolls back to start) but it was a bit sensitive to context and I couldn't reproduce it easily.
Were the videos in analysis mode or in normal mode ? (basically when you used the slider, was the video updated in realtime or only when you released the cursor ?)

About the suggestions,
It is not the first time that I get feedback around this idea of more locking in the synchronisation.
The original idea was to keep the videos fairly independant so you can change the sync point at anytime and maybe browse in one video while the other one stays paused.
Now maybe it would make more sense to really lock the vids together for as many actions as possible.
That would certainly ease the comparison process.

I'd be happy to get more feedback from other users on this too. Anyone using the double view for independant browsing of the videos ?

I'll have a look at FairPlay Lite.

Thanks

Do you guys know Elpel cameras? It's free hardware and software cameras.

Thanks for the link, it's very interesting. I hadn't heard of them.
Open source hardware in video could open so many possibilities smile

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.

Hi,
Which version are you using ? Is it 0.7.10, 0.8.* ? Is it an older one like 0.7.6 ?

When the problem occurs, you should be able to click a button to display the details of the error report.
Please post the paragraph that is under the line: ************** Exception Text **************.
This might help assessing what is going on.

Thanks for taking the time to report.

Salut,
Petite précision concernant la capture avec DF.
Pour autant que je sache la connectique FireWire n'offre pas assez de bande passante pour faire de la capture de camescopes HD.
Le flux qui est perçu par le PC est donc converti préalablement par le camescope en définition standard.

@tabory: Il n'y a pas de fonctions spéciales pour gérer les tablettes graphiques. Elles devraient rester utilisable dans les mêmes proportions que dans les autres logiciels.

Une personne qui utilise Kinovea pour faire du commentaire d'animations 3D avait suggéré que les outils de dessins puissent tirer parti du stylet et gérer notamment les différences de pression, comme dans un Photoshop.

À l'heure actuelle il n'est pas prévu d'intégrer ce genre de fonctionnalité. D'une part Kinovea reste un outil d'analyse avant d'être un outil de dessin, et d'autre part je n'ai pas de tablette pour tester. (même si je compte en acquérir une pour d'autres raisons).

@vaiotest: tabory parle de tablette graphique (à ne pas confondre avec un Tablet PC) - c'est un périphérique surtout utilisé par les graphistes.

Je n'ai aucune idée de la compatibilité de Kinovea avec le Tablet PC, mais a priori si c'est sous Windows XP cela devrait fonctionner.
Si tu peux l'installer et nous faire un retour se serait super ! tongue

Salut,
Je vais l'ajouter à la liste des suggestions.
Pour l'instant pas vraiment prévu, mais si ça intéresse du monde on pourra réfléchir aux modalités d'implémentation.

Hi,

For the slideshow function, due to a technical limitation which is currently out of my reach, the saving function needs to repeat the frames over and over several times into the output file, until the specified interval is matched.
Basically, there is a minimum of 8ms or something for the frame interval, so at some point frame repetition is unavoidable.
This frame repetition is causing the file to grow.

I don't think there is a solution to this issue right now and unless many persons find it unacceptable, I would rather work to improve other areas.

In a general sense, the file size of the various saving options won't be correlated to the original video because Kinovea will not use the same encoding profile than the original.
I had to weight several factors into account and file size suffered of the tradeoff (Couldn't find a reliable way to compute an adequate quality factor, so I use an arbitrary high value, which gives large files).
Thanks smile

Hi,

Here are the various activities involved in keeping the project running.
I'm awful at asking for help, suggesting areas, managing people etc. so I figured I would just list whatever there is. (What I can think of right now at least).
You may or may not have realised that it was this lot. Right now I'm doing most of the stuff apart from internationalised things obviously.
In no particular order.

Project Management
1. Establishing the long term direction of the project.
2. Choosing the mid term direction of the project.
3. Keeping all the users suggestions in a coherent list.
4. Assessing the potential and feasibility of the all suggestions.
5. Establishing release plans.
6. Making sure the short term decisions do not confilicts with broader goals.
7. Pronouncing feature freeze - (starting point of a formal release).
8. Packaging the release and uploading it to the site.
9. Making sure the main downloading sites have the latest version.
10. Keeping up to date about latest developements in related fields to get new ideas.

Communication
1. Posting blog posts about the project and future enhancements, media coverage, etc.
2. Translating these blog post from english to french or the other way around.
3. Posting some announcements or call for help and tests in the forum. Translating these too.
4. Filling the [s]super secret[/s] contributors wiki (en) (more on that soon hopefully).
5. Webmastering the site.
6. Answering questions about software usage in the forum.
7. Writing about the software in other forums.
8. Redirecting questions about the software in personal mails to the forum.
9. Chatting about possible future enhancements in the forum.
10. Answering requests from sports federations or private companies (and having no clue how to handle that).

Translation & documentation
1. Translating interface to new languages. (to all involved: thank you so much !)
2. Proof reading interface and help files in all languages available.
3. Consolidating the various localisation efforts in the language file.
4. Creating and maintaining the documentation (help files).

Quality Assurance
1. Doing basic testing.
2. Monitoring the bug report tool, reproducing reported defects.
3. Creating test cases to avoid regressions in future releases.

Code & tools
1. Managing scripts to ease release and internationalisation process.
2. Designing architecture at various scales.
3. Implementing features.
4. Creating or selecting icons and visual elements of the interface.
5. Fixing defects found in previous versions.
6. Improving features of previous versions, possibly removing unused ones.
7. Reconsidering architecture and refactoring the code so it's easier to work with in the future.

Needless to say, this takes a lot of (my free) time.
And beside my daily work (which is unrelated), I also have other hobbies tongue That is why you want to help the project moving forward.
Sure, I could do it all. But it's taking ages. The project is Open Source for this reason too.
