Hmm, yeah there are a few places where one millisecond is used as a time base, I guess this is one of them. It will break for this kind of framerate. I'll see to fix this.

Hi, sorry the article is a bit ambiguous. This menu appears when you right click directly on the video, not on any tool you've added before.

Re: Player in "two screen capture" configuration (3 replies, posted in Ideas and feature requests)

It can be a work around, but the best thing would be if the workspace is configured with two capture screens, the replay folder observer will still run maybe on a floating screen.
You can have the two instances of Kinovea running at the same time so you would see the two capture and the two players simultaneously. I don't know if this was clear from what I wrote.

Re: Exporting Data Issue (1 replies, posted in General)
How many data points do you actually have? Do you have a lot of data points and the export is not showing them? In that case that would be a bug, please send me the .kva file at joan at kinovea dot org.

Re: Using Kinovea for checking the long jump board? (16 replies, posted in Ideas and feature requests)
Yeah I followed this change, I find it a bit weird to be honest.
Is this change being implemented at all levels of competition?
I think it may be possible to do in Kinovea but probably there is a validation process by the federations.
Do we know what hardware and specs is used in the existing systems? I imagine this must be documented so federations and systems providers can comply.
There is also an undocumented "finish line" feature in the program that could help. It triggers for some machine vision cameras when configured for very few lines. This mode records the lines at high frequency and stack them to create "photo-finish" images and videos.

Re: 4 video windows (3 replies, posted in Ideas and feature requests)
Running multiple instances of Kinovea is the way to go when you need more than two screens.
Synchronization only happens within an instance so two-playback max.

Re: Player in "two screen capture" configuration (3 replies, posted in Ideas and feature requests)
Hi,
You can start a second instance of Kinovea and have one or two players there.
With the help of replay folder observers you can have these players automatically load the captured videos as they are created. For the case of two capture/two playback you will need to set each capture to save in its own folder, so the corresponding player can monitor that folder without loading the videos from the other.
Let me know if this matches what you were trying to do.

Re: Automatic video editing (1 replies, posted in Ideas and feature requests)
Yes I think there are several machine learning project exploring this, for automated cuts and match summaries for example.
I think it's outside the scope of Kinovea though. But it could be used as a pre-processing step to automatically cut down very long video sessions.

Re: Distortion calibration (2 replies, posted in General)
Hi,
Thanks for reporting about this.
The distortion model is the one from OpenCV.
http://docs.opencv.org/doc/tutorials/ca … ation.html
Kinovea solves for the three coefficients k1, k2, k3 (radial distortion). And the others (p1, p2, tangential distortion, and fx, fy, cx, cy intrinsic parameters).
When you run the calibration the coefficients found will be written in the log and should be available in the camera calibration dialog.
I imagine there are two places where this process could fail, either in the initial calibration, or when applying it.
You may be right that only one view is sufficient. I think the idea with multiple views was to have data in all parts of the image, as if you have only one view there might be corners with no data if the pattern filmed is at an angle. I'm not sure why it would fail with multiple views though, it worked in the past. I'll have to retry it.
It should also be possible to automatically find the corners in the image and avoid the whole process of manually placing them.
You can also tweak the coefficients manually to find a good fit. In this case usually only k1 and k2 are used.

Re: real-time tracking (2 replies, posted in General)
You can change the width of the lines, you need to edit the tool file though. I admit it's a bit thick.
Go to the program files and find \DrawingTools\Custom\openpose_body25.xml
In the section <Segments>...</Segments> find & replace width="4" by width="1" or something.
Unfortunately I can't really integrate OpenPose directly into Kinovea as it's only available for "academic or non-profit organization noncommercial research use" (per their license), which is incompatilbe with open source software.
And last time I looked the other projects doing posture estimation were also restricted to research purpose only for some reason.
Some more info about OpenPose in the documentation: https://www.kinovea.org/help/en/annotat … _data.html
Yes tracking is only done on the final video.

Re: automatically switching between capture and replay (1 replies, posted in General)
Hi, check the feature called Replay folder observers:
https://www.kinovea.org/help/en/capture/replay.html
The way it works in Kinovea is that you point the player to a directory instead of a file, and it will monitor that directory and automatically load and play any new file created in that directory. So you can point it to where the capture instance is saving the files and it should create such a capture-playback feedback loop. For two-camera system you'll need to configure the capture to save into different folders so each player loads the matching one.
Another way if don't care about archiving each swing is to use the delay feature. If you set it to 5 seconds or so, you can just look at the capture screen for an instant live replay.

Re: two separate default workspaces? (2 replies, posted in General)
Hi,
Yes, this should work out of the box. Each instance has its own preferences file. When you click on the menu Options > Workspace > Save as default workspace, it saves the workspace directly in that instance's preferences files. So if you do that on your second instance, it will save it for your second instance only. Each instance will now have its own startup workspace.
If you want to experiment and backup your original workspace, you can go to Help > Open log folder to open the directory where the preferences are saved. You should see a "Preferences.xml" which is the master one, and "Preferences.2.xml" for your second instance (or another name if you start the instance with the name flag). You can copy the "Preferences.xml" somewhere else to back it up and then experiment with saving default workspace in various instances.
Another way with more control is to save the workspaces in external files instead of directly in the preferences, by using the menu "Export workspace". In this case you can create shortcuts in Windows for each instance and have them use a specific name and workspace file. This way it it's more explicit and doesn't rely on the sequence of launch.
