Then as I recall I just played the rest of the video and it did it all magically. The context menu they talk about is invoked by right clicking on the little dot you've placed on the image of the end of the bar, the "cross marker" they talk about.
#KINOVEA VS DARTFISH HOW TO#
How exactly do you track bar path? I looked under help and it says to use the "context menu Follow Trajectory" but I can not figure out how to switch modes.I outlined it in a previous post, (wfs) and covered the tricky bits, which are mainly where the options displayed don't match the text in the help. This is really a useful tool for a USAW coach. I missed one lift and noticed that my back angle was 10 degrees greater than all the other successful lifts.
#KINOVEA VS DARTFISH SOFTWARE#
The software does have the ability to calculate angles and I played around with that a bit while studying my efforts. I suggested to add the ability to calculate trajectory speed and acceleration like Dartfish does. I also posted on the Kinovea forum with a link to my youtube video. I think the response will be very positive. I have posted a link to the software on 2 weightlifting forums used heavily by USAW members. So aside from the speed graphs, there isn't much this can't do for us. I think there's some provision in the software to measure angles, I know it can draw lines and I think there's a way to calibrate the distance measurement against a known distance on the image (the diameter of the plates seems ready made for that in our case).
Hopefully others will also find it a useful tool.Īfter watching the other youtube videos posted I now have a much better idea what I should be looking for in the "wiggles" and I'm going to have a play with that back angle measurement stuff too. I was hoping it would make its way into USAW hands. Pretty stoked about the lifts, even more stoked about the software!Īs a coach, this will be an awesome tool in the toolbox. I missed a first attempt at 285# but then came back to nail it. I maxed out in the Clean and jerk today performing and videoing lifts of 225#, 245#, 255#, 265#, 275# and 285#. First time I have ever used it and pretty cool stuff.
This video is from my use of the software today. Oops, nearly forgot, I was going too fast. The trace feature is available in the stable release too, but may not work as well?Īctually there is some ability to export data to spreadsheets for analysis, but I haven't explored that. I used the experimental 0.8.4 ()version () of Kinovea. The output file format is not a common one, but it's also not unusual and it's not hard to find something that will view it. In this case all I had to do was select which segment of video I was interested in, click on the image of the end of the bar and tell it to trace the path, then save the resulting image. Not even remotely criticising Annie's technique ) it just happened to be the first video in the Olympic lifting section of the mainsite exercises and demos page. I've uploaded a video I processed of Annie Sakamoto cleaning to YouTube. Given a side-on video of an Olympic lift you can select the end of the bar and let the software track it for you and draw the path of the bar throughout the lift.ĭartfish will also give you data on bar speed etc, but for most of us, it's the bar path that is most telling. Well after a year of searching off and one I've just found an open-source application called Kinovea () that does some of the same thing. That's normally done using an application called Dartfish, which costs US$1000 for the basic version and does so much more than just bar path tracing that it's a minor feature. You know how in many Olympic lifting videos they show the lift from the side on and superimpose a wiggly line on the clip which traces the path the bar takes?
