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.

Hi,
You could use :
Manufacturer/producer: Kinovea open source project.
or just www.kinovea.org

And due to this open nature, there is no "country" of origin, there is no company or formal organization. It is the result of the contributions of several individuals from all over the place.

I've always had mixed feelings about this tongue
Over the years I got used to Kinovea not having a main toolbar… but well, I guess they are popular for a reason.

This will probably be tested in next experimental version, don't hesitate to speak your mind whatever you think.

Reminds me that "series" of keys have been suggested for other functions too:
- shortcuts to activate each drawing tool.
- shortcuts to automatically create a key image with a specific name (with a manager to add/remove instances depending on user application).
- shortcuts to automatically create a label in the image with a specific text. (similar as above for storing the list of possible text).

Can there be a keyboard shortcut to select/switch screen? Something like an "alt+tab" combination in windows.

Page Up/Page Down is supposed to do that currently. It only works for dual playback though. (And the key mapping is not intuitive).
CTRL+Tab is generally used to navigate through tabs in an application. That would probably be a better fit…

Also check the which camera do you use? thread, it has interesting information. (And everyone is encouraged to post his/her experiments with any device there smile)

Live capture with USB is possible only with webcams unless you have a very specific camcorder that can do it (webcam mode?).
In general it would seem the new camcorders (storing to SD card or DVD) cannot stream live to the computer through USB or only at reduced resolution.

One solution suggested is to use the analog output, and then hook to an Analog/Digital converter card on the PC (see the other thread).
It will be interesting to see if they release camcorders with USB3 streaming though…

(Note that the first 2 messages of this discussion are rather old)

Regarding the animated GIF front, they are indeed supported by .NET natively so there's hope for support in Kinovea for the future.
It will need some architecture work to integrate with the existing, so this will be for mid-term future (not before the next official release).

Animated GIFs would certainly be a plus. (Baseball community seem to use them quite a lot)
The decoding library doesn't support them as far as I can tell, but now that I think of it, maybe there is a way directly in .NET or another library).
Problem with GIF is that they don't have a defined frame rate, each interval between frames may be different.

Raw sequence of images would be a nice input too.

Awesome ! Thanks for the feedback smile
The problem with the second screen is general and exists even for different models.
When the second screen is created, it doesn't realize the first camera of the list of devices is already streaming to the other screen and it tries to connect to it. It doesn't fail, we just get a black screen…
Apparently it's a bit tricky to know if a given device is already in use by another application. However detecting that it is used by the other screen should be doable… (The hard part is not to break the automatic reconnection mechanism)

Yes, it makes sense smile

So,
CTRL + Key = next 1% spot.
Shift + Key = next 10% spot.
Key alone = next 25% spot.

Respectively Left / Right for the decrease/increase of the delayed during live capture.

----------------
Regarding capture and left/right reversal.
The idea was that when you press pause and the buffer is frozen, you would want to use the same interface for playing back and step-by-steping the recent frames.
I think the most intuitive way for playback is to have a left-to-right navigation, left being the start of the video, right being the end. (as in the playback screen).
So in that case it would be better if you can go forward in the video by pressing RIGHT.

Let say the user didn't apply any delay. Slider is all the way left. Left end is most recent, right end is oldest.
As soon as you pause frame grabbing, we will want to turn the slider over so that left is now start and right is now end. Maybe even force the cursor back to left.

At that point sliding right (with mouse or keys) should make you go forward in time. This will be the opposite of when live capturing where sliding right makes you go back in time.

(Maybe the reversal of the function will not be so obvious, I don't know.)

Yes I think the PS3Eye driver is one example of a driver that doesn't support 2 cameras connected at once.
(Unless using the SDK that the people at CodeLaboratories propose, but it means developping code specifically around these devices).

Ah oui désolé je me suis trompé smile
Cette fonction n'est apparue que dans une version ultérieure.
La version expérimentale est accessible depuis le sujet attaché en haut de ce sous forum. Ici pour la 0.8.13.

the whole legs are blurring and sometimes it's appears to go forward - backward for a while.  Maybe there is a setting I need to change or a de-interlacing issue?  I don't know...

Yes exactly, it looks like combing from interlaced frames. Try with menu Image > Deinterlace.

Also, just for additional info, the SiliconCoach people told me to have at least a Core2 cpu, so maybe trying to use my old P4 system for anything other than web surfing and email is not practical any more.  What I'm kind of trying to figure out is if Kinovea would run fine on the new Corei3 cpu that have the graphics build into the cpu (2100/2200 I think)?

I'm afraid I'm not very knowledgeable when it comes to CPU types and power smile Maybe some other users can give their experience with regards to hardware specs.
Currently most of the drain is on the CPU but there is a sub-project to get the rendering done through Direct2D, which should leverage hardware acceleration from the Graphic card and give a good performance boost.

Last, do you have a release schedule for the beta?  Just wondering when the next version might be coming out?

Next experimental version should hopefully be released begining of april.
The next official version will be released when the current one is stable enough (no new features are planned) and after translations/manual update.

Hello,

One scenario that haven't been tested (to my knowledge) is how the program reacts when two cameras of the exact same brand and model are connected to the computer.
If any one can test this setup, please report. (experimental version 0.8.13 needed)

When clicking the configuration button, does the device list display two different entries ?
I realize it may also depend on the device driver, since it needs to be capable of handling two devices at once.

Thanks

I have loaded in two standard definition videos (captured from a commercial program) and the playback seems choppy and the speed of the playback seems inconsistent.  Is a more powerful computer required to playback 2 video screens?  Should I install a different version of .net or some other software?

Do you have this for all videos or only these specific ones ?
There can be some issues of jumpy playback with some instances of H.264 files.
If you see the speed slider moving to the left by itself, this indeed indicates that the program has trouble keeping up the pace. (do you know the frame rate of the video ?)

I do have SiliconCoach running on a powerful system, a Core2Quad 9550 Windows 7_64 with 8GB RAM and a GeForce GTS250 video card.  I could install Kinovea on this system if you're sure it will not affect my SiliconCoach installation.  Please advise.

I cannot think of anything that would affect your existing programs. Files are installed in Program Files, there is one entry in the registry to remember the language of installation.
Most notably, Kinovea doesn't register itself to open any file type or to be launched when a video device is connected to the machine. (I know some other softwares do that but personally I find it a bit intrusive)

And regarding your last question, no, there is currently no functions that would work on the two capture screens simultaneously.
Thanks

My experience today told me that it would be good if after capturing a video (you get a little vignette under the main scrren) it would be great if you could double click directly that vignette to read it or better if you could right click on it and have a menu to open it rename it etc...

Thanks for the feedback, also check the other thread for capture screen suggestions.
