<![CDATA[Kinovea - Forums]]> 2026-07-03T04:15:51Z PunBB https://www.kinovea.org/en/forum/index.php <![CDATA[Unhandled crash after adding tracking to perspective grid]]> I'm using Kinovea to track particles of rock being ejected from a mining blast. However, if I add tracking to the perspective grid I am using for calibration, after the grid has been moved any additional tracking I try to complete causes the app to hard crash without an error message.

Repro:

1. Add a perspective grid and track it as the camera repositions.
2. Finish the perspective grid tracking once the camera has settled.
3. Being tracking other items in the video
4. Once enough time has elapses that the perspective grid tracking has finished, attempting to track anything else causes hard crash - no error message is shown.

This issue persists even after closing and reopening the application. Has anyone else experienced this, or is this a known issue with a work around?

**EDIT**

It has now given an error before crashing:

See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

I've recorded some activity in slow motion on my phone, with NO annotations, comments or drawings, transferred it to my computer, and then used Kinovea set a Working Zone prior to exporting. To the best of my memory, this is the way I've always done it.  The result today is a HUGE file that I cannot use because of its size.   I've read the documentation repeatedly, and looked online for help.   There is mention of a "Save video only" option in the export dialog, but regardless of how I reach that point, whether "File/Export Video" or right click on the trimmed video in the player screen, or select the middle icon in the Export Toolbar, I am not presented with any option to "Export video only".   I've also tried selecting the box for "Take slow motion into account" and I get the same result whether that is selected or not.

The REALLY weird thing is that as recently as last week, I was able to export a trimmed video with no annotations and no drawings or comments, and the result was a much smaller file.   I have never had to compress the file to get the desired result.

I have not (at least, INTENTIONALLY) changed any options, and I get the same results on both of the two computers I use for Kinovea.

So I feel like I must be doing something wrong, but with apologies, I'm going to request some guidance....

Any help appreciated.

Thanks

I am looking for the Kinovea 0.9.6 (64-bit) version, because it is the last stable release that includes RTSP support (Camera → Add IP Camera (RTSP)).
The recent 2025.x versions do not seem to include this module, and 0.9.6 is no longer available in the official archives.

If someone still has the installer or a working download link, I would be very grateful.

Thank you!

The result was the same: splash screen appears, then disappears, but the application never opens.  Is Kinovea compatible with 25H2? (.NET Core 8.0.28 is installed. .NET Framework 4.8 is not listed as installed. However, when I attempt to install it, I get a message saying it is already installed. [So, it's included in .NET Core 8?]) Any help would be greatly appreciated. Thanks.

I need to analyse continuous x-ray images as part of my work. I previously would analyse them in VLC with nil major difficulties however there was no option to move backwards frame by frame. This brought me to Kinovea.

I downloaded Kinovea today to test the video analysis and I've found they're playing at double speed. The x-rays themselves run at 30 fps but when uploading them to Kinovea they are playing back at 59.94 fps. When I checked the video files themselves, I realised they're saved at 59.94 fps, but when putting the same file back into VLC it plays with nil difficulties.

I thought adjusting the time calibration would fix this, but it just changes the time it's saved as.

Am I missing anything? Is there a quick fix?

Cheers

I'm using Kinovea 2025.1 with two recorded videos playing in the same window. Each video is 10 minutes long. I need to add a plus sign (+) throughout the video. After a certain number of plus signs, the application closes automatically.

When using version 0.9.5, the error described above does not occur. However, the images with the plus signs do not appear until the end. For example, if the video has 10,000 frames, the images with the plus signs (+) only appear up to frame 8,000. Therefore, I cannot access frame 9,000 by clicking on the image that already has the plus sign.

I need to access the exact frames of the previously added plus signs.

Currently, this is only possible if I open two players of the same video and use a zoom tool on each screen. I believe this is a simple feature that would be very helpful.

I record my golf swings using Kinovea, but want to import them into a piece of software (called OnForm) that then converts my swing into a 3D model with associated golf measures. OnForm requires a minimum fps of 120. In Kinovea, under Preferences / Capture / Recording, I can set my High Speed Camera Framerate replacement threshold to a 120 (or even higher), but I don’t seem to be able to have a replacement framerate of more than 100.

Am I correct that it’s this latter number (100) that is the fps for recorded videos? OnForm seems to think so and so rejects my videos as being not above 120fps. Is the 100 maximum a Kinovea maximum or is it a function of my PC or something else?

Any ideas much appreciated!
