Great Tutorial. I have thing I'm trying figure out how to solve. I use Kinovea for analyzing rowing on water. Taking video on the water is not a stable thing, as you can do on dry land and mount your camera to the ground. Therefore my object (the boat and rowers) are moving, and my camera is moving too. Is there a way to, lets say set a tracking point on the boat, as a reference point, where i.e. a perspective grid is moving along with the tracking point. The thing with rowing is, that we must be able to see both the rowers together in a team boat and the oars at the same time, and then from there do the measurements and timing. The perspective grid is great to measure positions in an eight, but the frame after, the grid does not fit anymore, because both the camera and the boat has moved - and by the same path.
I would suggest using GPS on each boat as it will allow you to track the relative velocity which would allow you to calibrate your velocity for the video. I believe you can import a continuous data series to Kinovea now, so you would be able to display a graph of relative velocity overlaid on your video. I haven't tried this, but I do remember reading it in one of the release notes.
Hi, you might use tracking on the perspective grid itself and the coordinates and measurements of other objects will be in the moving coordinate system of the grid, so it's a way to "stabilize" your reference. Another way is that in the latest version (2024.1) we added a function to compute the camera motion, this is not quite compatible with measurements yet but I would be interested in looking at the sort of videos you are working with to see if it will work.
Hi! thank you so much for the tutorials, do you know how to include the angles relative to vertical (or horizontal) in the angular kinematics graph? It would be so helpful. Thank you!
Yes! If you place your relative angle tool on the desired points, right-click and select tracking --> Start tracking. Track the angle until the end of the movement and then use the same menu to select Stop tracking. You can then go to tools --> Angular kinematics and export the relative angle.
@@LetsTeachScience Thank you! I couldn´t visualize the graph because I had an old version. Now I´ve updated and it all works as it should. Greetings from Argentina!
Great video! Just curious, if I calibrate horizontally instead of vertically like you did in this video (i.e. like if I used the width of the door in the background of this video to set the scale), will my X & Y axis values that I export to excel be flipped? Sorry if that question doesn't make sense.
1" foam balls from a craft store, cut in half then color in a dot with a sharpie. I've found that double-sided carpet tape or toupee tape works best to secure the markers
Why do I not have the same options when right clicking on market to track? I right click select TRACKING and my only option is START TRACKING. I do not see the 2 tracking boxes. V9.3
You should not need any additional plugins. Since this is an experimental version of the software, I would suggest reporting the bug to their bug tracking forum www.kinovea.org/en/forum/viewforum.php?id=2
Yes, follow the section in the video that shows you how to set the measurement units. There is a bug that makes you force the unit update each time with this version.
hey can you share me the kinovea .exe file, I’m not able to download from their website, both . exe and zip files are corrupted. Please help me out, urgently required for my project
Make sure that you calibrate the pixels to a known reference measure, and then any line you draw or marker you track will be scaled appropriately. Also, make sure that you have updated the measurement units to be in m or cm as they are likely being exported in pixels.
Thank you so much, I am preparing for my assignment of biomechanics course, this video helps me a lot.
Glad it helped!
wondful, Great help for me。

No, the axis system will remain the same. You can display the axis on your video, and move the point of origin around as well if you want.
Nice work!
Thanks!
Hi ! Thank you for the different tutorials. What markers do you use for the different articular position ? Thank you in advance
1" foam balls from a craft store, cut in half then color in a dot with a sharpie. I've found that double-sided carpet tape or toupee tape works best to secure the markers
@@LetsTeachScience toupee tape! excellent.
Thank You!
You're welcome! Check back for more videos in the future
hi, i love the video. anw where i can buy those body market set?
Any craft store, they are just styrofoam balls cut in half.
Why do I not have the same options when right clicking on market to track? I right click select TRACKING and my only option is START TRACKING. I do not see the 2 tracking boxes. V9.3
Likely the boxes are just very small, if you go into configuration you should be able to see the option to adjust both windows
This is great, but by Tools bar is not visible and I cannot choose Linear Kinematics. Where is my tool tab?
Hi, most likely you are using an older version of Kinovea. The great news is that they've finally released a new stable version (9.5)!
2:44 . The bug for me isn't fixed , any suggestions ?
Fortunately, there is finally a new stable release (V9.5) that is available for download on their website www.kinovea.org
@@LetsTeachScience thanks
Thank you so so much.
You are so welcome!
I used a smartphone camera to record but it keeps crashing when I try to open a video. Do I have to add some plugins?
You should not need any additional plugins. Since this is an experimental version of the software, I would suggest reporting the bug to their bug tracking forum www.kinovea.org/en/forum/viewforum.php?id=2
Export your video to a laptop or desk top where you have downloaded Kinovea. Easiest way to do it, bigger screen, too.
Great video!
Stupid question: Where do you get these markers?
They are just 1" styrofoam balls from a craft store, cut in half, then draw circles on them with a black marker!
@@LetsTeachScience How do you attach it to the model's clothing?
How to add stop motion for analysis in Kinovea? For example: video - stop motion - video, how?
I'm not aware of a way to do this in Kinovea, though I haven't tried. You may want to post your comment in the discussion forum on www.kinovea.org
I can't seem to get a path following when using the tracker option. Any advice?
If it's following, but not displaying the path, you can access this display option using the right-click menu
Hello... thanks a lot for your tutorial... but my speed unit isn't changing to m/s. could you pls help?
Yes, follow the section in the video that shows you how to set the measurement units. There is a bug that makes you force the unit update each time with this version.
amazing
Thank you! Cheers!
Why is there no tracking for human model?
The leg only goes from 0 to 130. why does he have 170+?
hey can you share me the kinovea .exe file, I’m not able to download from their website, both . exe and zip files are corrupted. Please help me out, urgently required for my project
I’ll share my email, please help me out
Hi pls help, my school has task me to use kinovea to track horizontal distance, but when i export the data is all messed up!!! pls help!!!!
Make sure that you calibrate the pixels to a known reference measure, and then any line you draw or marker you track will be scaled appropriately. Also, make sure that you have updated the measurement units to be in m or cm as they are likely being exported in pixels.
