- The thickness of the line drawing tool has changed. The thinnest size is now about 10 px. It would be nice if it would only be 1 px. Also it should not increase the size if the video is zoomed.

Yes, it seemed more natural that the line width increase when zoomed in…

Another nice feature would be to have the "shift" functionality from other programs which limits the angle of the line to 45/90 degrees to get horizontal or vertical lines.

On the todo list. Hopefully for next version or the one after, as the focus will be on drawing tools anyway.

Also for me it would be better if the thumbnail bar would not open automatically when a drawing tool is used for the first time.

Hmm. You can always fold it back down manually, I don't see any other way to do it. If the bar doesn't open automatically, the user won't know it's there.

- For me it would be nice to have a simple thin cross over the whole capture image as observational reference. This would be nice to set up the camera an i don't have to load my custom image.

A visual aid that would be loaded automatically each time you launch the camera… That sounds like a job for the "auto load kva" feature, check this thread. Post more questions there if it doesn't work as planned.

- A nice feature would be a "jog dial bar". Similar to the speed bar it could play the video forward and backward with variable speed. Slow if you just pull it a bit and faster if pulled more.

I'll have to watch videos of this to better understand the user interaction.

- Shortcuts for record start/stop would be nice.

CTRL+Return or CTRL+Space.

Thanks for the feedback.

Bonjour,
Non, les coordonnées des points ne sont pas exportées dans les données tableur… C'est effectivement une lacune qu'il faudra combler.

The last selected camera is not stored anywhere. The camera selected by default is the first camera coming up in the list that DirectShow returns. I'm not sure how this list is sorted.
This is something that might be done in the future. (But I'm still not clear whether a camera can be uniquely identified by its moniker string alone. (cf. two cameras of the same brand/model)).

Thanks.
I reproduce the issue for persistence. The code was commented out at some point when the format changed. Some refactoring is needed.

Which camera setting is buggy ? I can't reproduce.

This feature was introduced in version 0.8.16 but hasn't been described so far.

The idea is to have a standard set of drawings loaded automatically each time you open a camera (or video).
This could be useful in a fixed setup, where you can prepare measurements marks, custom grids, etc. and have them loaded as soon as the camera goes live.

How to do it:
- Open a video.
- Add your drawings on the first frame of the video.
- Save the analysis data (-> KVA file).
- Copy this file to the application data directory : %appdata%\Kinovea (You can also open this through "Help > Open log folder").
- Rename the file to "capture.kva". Done.

This will also work for the player screen, the file has to be named "playback.kva". This time the drawings can be anywhere in the video.

Until I find a better solution (like upgrading the forum software and install a specific plugin), I'm temporarily disabling new posts for new users of which I haven't checked the profile yet and validated that they are not spam bot.
Consequence: After you register it may take up to one or two days until you can actually post in the forum. Sorry for the inconvenience. I'll try to fix the problem ASAP.

Absolutely no impact for existing users.

Thanks for the file.
Unfortunately I don't have a solution for the AVI right now… Will have to study the problem more in depth.

Do you by chance still have the .seq file from StreamPix around ? (Or the possibility to create a new one).
(At some point) I will be interested in studying the raw format for interoperability purposes.

Thanks for the video, it will help.
I didn't know about this software, it looks quite powerful.
I reproduce the issue, it's like the video is loaded fine but images are decoded to black or transparent.

During the capture process, do you specify a particular codec for encoding the AVI ? If so which one ?

edit:
After a quick test: the images are there but for some reason the alpha channel on each pixel is set to 0, so they are entirely transparent.

I notice that which USB port I plug into first makes the difference. Took quite a while thru the trial and error process but persistence pays off!

Maybe it has to do with the USB root hubs vs normal? I seem to remember that some USB ports are more important than others. In the device manager, you can see some are "root" while others aren't.

Maybe if you connect the two cameras on ports that ultimately go to the same USB root hub, it won't work as the driver will be loaded only once and detect that two cameras are plugged. But maybe if they are connected to two different root hub the driver is loaded twice and both work independently… (?)

This should be improved in 0.8.17. Please retry with this version and report.

Oh, I thought I had posted an answer here…
Anyway, I'm not sure what you mean by "it does show as a high speed camera" and "try to change back to a standard webcam". There is no concept of high speed camera in the Capture screen. The list of camera under "source" is the list of connected devices (+ a special device for network cameras). The high speed camera menu is used exclusively to adapt timing in the playback screen.

Please install 0.8.17 and retrieve the logs of when the problem occur. You can attach them to bug report 274.

I'm not quite sure how to reproduce the problem. I load two videos, synchronize on a common event, then use the blue buttons of the WZ bar : http://www.kinovea.org/help/en/selectionsmall.png Is it what you are doing that causes the problem ? If not please describe step by step.

Some notes:
- When the working zone fits in the cache capacity, it is loaded in cache and you may see a progress bar dialog. The dialog should disappear when all images are loaded.
- When you change the working zone of one of the videos, the synchronization point is reset to 0.
