Hi everyone!

I'm happy to finally publish Kinovea 2025.1. This is a major release.

Links
   
    Kinovea-2025.1.0.exe (installer)
    Kinovea-2025.1.0.zip (self contained "portable" archive)

The change log got so long and hard to read that I decided it was time to improve the presentation, you will find a list of the changes here: What's new in Kinovea 2025.1

Big thank you to every one that helped test the new features during the past few months!

I started to update the manual to reflect the changes, I will continue to update it in the coming weeks.

Translation coverage also took a hit with all the changes, you can help the translation effort on weblate. There will be minor releases periodically with translation and bug fixes.

Let us know as soon as possible if you find any issue.

I just found the following problem related to languages: if you use the installer and install on top of a previous version it will use the old resources for the languages and will display untranslated elements in the user interface.

In general I suggest uninstalling the previous version before installing this one.

In the trajectory configuration tool window, when changing the size of the search window, drag the value from the object window width field to the search window height field.
In the new tracking tab in the annotations panel, it works correctly.

Thanks, I see what's going on. I made a fix but I was actually considering removing these settings from that window and only leave the style options like for other drawings. The annotation panel should be the main way to interact with it and it has all the options now (match and update thresholds).

awesome stuff in this release!

I am noticing when my files auto-replay, that the playback speed drops to either 10% or 0% (and doesn't play), but if I set to my desired replay speed of 20%, it plays at 20% and then reverts back next time a new file is observed.

Is this a bug, or am I missing a setting?

It sounds like a bug but I haven't experienced it so it might happen in a context I haven't tested. This behavior of decreasing the playback speed automatically happens when the player starts the playback loop but can't keep up the pace, typically because it doesn't have enough resources. First it skips frames, then skips multiple frames at once, if skipping frames is not enough it starts lowering the frame rate.

Normally it settles down to whatever it can manage. Since you say that manually changing the speed works, it seems there is something that makes the system busy specifically when the file is opened for some reason.

What is your window/screen setup? Try with one window for the capture and a separate window for replay, this should better spread the load over different CPU cores. If you have two cameras and a dual replay, make sure the files don't go to the same folder.

Do you have a default annotation file that is being loaded in the player?

Another idea, are the files saved to a folder that is synchronized to cloud storage, like OneDrive or Google Drive?

I had one window for dual capture and one for dual replay. The issue still happens when using a single capture window and a single replay window.

Both videos go to different folders, which are not synched to cloud storage. I do not load an annotation file.

With the single video, CPU is hovering under 50%; for dual video it's around 80%.

I have capture set to record 3s delayed for 1.60s and 1s idle time. Agree that typically it drops from 25% speed, to 20%, then to 10%, and ultimately 0%. I have the same setup I did before the upgrade, after the upgrade is when this issue started happening.

Any other ideas?
