Hello,
The next version will be focused on drawing tools.

- measure horizontally/vertically from a base line I can draw myself

Can you give more details on that please, what is the scenario ?

jonh wrote:

- measure the angle between 2 unrelated lines

This would be interesting but not sure how to interface with user. (How to specify the 2 lines, where to display the angle). Maybe as a special tool.
Please also give usage scenario or expected user interactions.

- overlay 2 still images made partially transparent

Check the image tool from menu Image > Observational reference > Import image…
Then right click the image and change opacity.

- ability to export into open office writer type document

There are some plans for a "rich" export with key images, comments and all, but currently there is no time to do it right, so it's on hold.

Are you indoors ? I think he PSEye webcam needs a lot of light, otherwise the signal is quite noisy.

The basic scenario would be:
- Save the analysis in separate file (.kva).
- Send the .kva along with the video.

If the .kva has the same name as the video and is in the same folder, it will be loaded automatically in Kinovea when they open the video.
You do not need to re-encode or otherwise export the video, use the original file.

Ok, but why is the lowest thickness setting 10px?

It's not, the small size is 2 pixels wide… But it gets scaled with the video. Are you sure you are not stretching a small video ?

edit: I'll add the 1px option back in the option list. I'm not sure why it's not there…

- 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…

sven wrote:

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.

sven wrote:

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.

sven wrote:

- 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.
