I cannot give an estimated time, there are too many other factors.
I started to look into this. One idea I had was to add a function where you right click an existing named keyframe and do "Set as preset X" or something like that. Then I realized that instead of having just the name of the keyframe we could save all the data associated with it and use *that* as a preset maybe. This way you can add a rich keyframe with some pre-made drawings in one click. There is also a feature for keyframe "color" that would fit nicely into this.
So now I'm thinking that instead of saving this as a list of names in the preferences, it might be simpler to have a "preset KVA" that is a normal annotation file but containing many presets for keyframes and drawings. I think this could simplify the logistics for the more advanced automation scenarios. In the preferences you would point to your preset file, it would analyze it and then for each shortcut/action slot you would select the thing to add based on what's in the file.
edit: scratch that, it would be too complicated to setup. I'll stick with simple name+color presets.
Hi, thanks for the follow up and the details.
Regarding the menu, you may be using an older version or there is a problem. The context menu is generic and should look like this:

You can also change the camera icon from there to identify it better.

Sorry, the error message is not very helpful. I think what's happening is you are trying to open the KVA file as a if it were a video. The KVA file only contains the annotations. Open the original video normally and load the KVA file into it using File > Load annotations… If you have saved the KVA file next to the original video and with the same file name, it will load it automatically.

Right click the camera then "Rename" menu and set the "Alias". Does this work?
"Use motion synchronization mode", this is still experimental. The idea is that instead of synchronizing the videos on a common event by shifting one in relation to the other, this mode uses the length of each video segment and changes the playback speed of the right one, such that both the start and end are in sync (but they are no longer using a comparable time base).
Basically it's a way synchronize a whole segment by scaling the time axis in addition to translating it. This can be helpful if you want to compare form within a larger motion while doing abstraction of the performance speed. For example say we have two long jumpers and we want to compare their form during the aerial phase, but one jump is taking longer than the other.
Regarding cameras that have the same name. In the log there should be a line with the camera identifier. This is normally a unique name, it's the DirectShow name. I think I've heard about this issue with the Kayeton cameras. Can you check in the log if they have the same "moniker"?
There is not a way to manually input the coordinates from within the software.
The only way would be to create the KVA file with the coordinates in it. This is an XML file, you can create a test file to see how it looks and try to put your data into it or generate one yourself.
Thanks for the follow up.
Can you describe the configuration that doesn't work so I can reproduce and fix the issue?
How was the webcam "deactivated"? Is it in Windows settings? Is it something specific to that particular webcam?
You don't need to have a camera to use Kinovea, but it will look for connected cameras on start up and prepare a thumbnail for each connected camera in the background. This is an optimization but maybe it's causing more trouble than it's worth.
You're right, I think people that wanted to do this with labels were also essentially tagging the whole frame as a particular event. So being able to create named keyframes on the go as the video plays should fill the same use-case.
Not for center of mass per se, but since it's mountain bike maybe from the wheels? Measuring rotation per minute and knowing the radius?
Would have to test this on controlled footage first to get some error bars.
There was also a request for automatically creating drawings of a certain type.
I think it should be doable but not sure about the form factor.
Maybe something in two steps: 1. a number of "dynamic commands" added to the shortcut manager, where you can bind the keyboard shortcut you want. 2. in the drawings preferences a place to define the action corresponding to each dynamic command.
It would be simpler if all the actions have a simple format, for example create X and just one argument for the name. But I think people would use this a lot to add labels, so it's important that this can create labels with specific text.
@Martin, your problem is different. Based on the log it's possible the newest runtime from IDS is no longer compatible with the SDK I used to make the plugin.
For the problem of the crash with no error message in the log I'm not sure where to start and I don't know how to reproduce the problem to investigate it.
Hi,
This is not implemented and at the moment it's not on the roadmap.
You can use a dedicated software to capture the screen. OBS is free and open source.
Yes that's correct. You should get all the frames, they are just spread out more in time.
If I recall correctly this is written in the log at some point during recording. Otherwise it is saved in the .KVA file produced along the captured video, but if you opened it, modified the value and saved back it was most probably overwritten. However if you recorded multiple videos the same day one of the KVA file might still have it.
There are two log files and they roll over based on file size so there should be history for a few recording sessions in there.
