automatic swing recording and slow motion playback with kinovea

[htdumps]

here is the script updated for kinovea experimental version 8.26.

Wow! thanks for all your hard work man!!!

[Christoph8840]

I got the following error message. Also vlc doesnt even react. What do I need to change?

[Christoph8840]

[inorkuo]

is kinovea creating recordings? check that kinovea is set to record to "D:\Swing_Videos". also make sure you are using the 32bit version of vlc. it looks like you are missing a quotation mark for the line in audio zone trigger but i'm not sure that it makes a difference.

This looks interesting, I have an old ps3 eye camera, do you need a driver to make it work on a pc running windows 10? If so, where do you get it? Thanks!

[inorkuo]

yes you need a driver. you can get it here https://codelaboratories.com/products/.

[Triton]

Thanks so much!

Is there any way to have the script work using a C: Drive ?

[inorkuo]

Yes you can tell the script where your recording directory is by passing it as a parameter

Thanks inorko for all your work...This is awesome...I just installed all the software and started the setup in Kinovea (0.8.15), but can not get Kinovea to recognize the second camera. I have two OV2710's, Windows 10. The computer and Kinovea recognize both cameras, but I can't get a picture in the second window. Down at the bottom of Kinovea window it show's the camera and:

"HD USB Camera - 640x480 @120 fps (0.00 fps, Buffer 0%)"

I've switched cameras, computer USB ports only, with USB hub, without hub and get the same the results. It will allow me to use the computers Webcam in the second window, but not the second USB camera. Does anyone have any thoughts on what I might be doing wrong?

Thanks in advance for any help!

[StodgyBarley]

You have to manually start the second camera.... not sure if you tried that or not? There's an icon there to start the second one at the bottom left of the second window. I had a similar issue for a bit until discovering the icon.

[wzjy47]

Thanks for your quick reply but I don't see anything that resembles a "start" icon? I clicked on the "setup" icon and selected the second HD USB Camera, but nothing happens. When I select the integrated webcam, that works and shows a picture in the second window.

[StodgyBarley]

The button is at the bottom left underneath the new window. It's a camera with a gears icon on it.

[G4zzel]

Theres a way you get it to work.
First unplug one of them
2. add one camera on the record video whit one camera.
3 plug in the second camera
4 switch to dual recording
5 add the second camera on the one side Thats black
that should get both up.

it was a couple of months since i did this so i hope i remember correct

[wzjy47]

Thanks for the reply...I did try this and no luck...

[StodgyBarley]

wzjy47 Here you go. That starts it up and then you choose the new camera from the pop up window.

[wzjy47]

wzjy47 Here you go. That starts it up and then you choose the new camera from the pop up window.

Thanks...That’s what I had tried...It shows up in the bottom of the screen with the buffering at 0 and no picture in the window...When I select the computers webcam, that does work...

[StodgyBarley]

Bummer... any chance you're running too many USB devices off of one port and it's under-powered? I have that happen from time to time with my PS3 Eye camera for DTL view. I have unplugged a few items from a powered hub and that has solved the trick a few times, although not always. I do get a picture normally and it can be choppy. I am going to try an active USB repeated cable though with my second camera even though it runs through powered USB hub. I have quite a distance between my camera and my desktop... like 40 feet of USB cable and then the powered adapter tho.

[wzjy47]

Its possible, but I don't think that's the issue...I tried it on a different desktop and had the same problem...I'm not sure I tried the shutdown procedure mentioned above though (I'll have to give that a try at some point)...On the other desktop, the standard webcam Windows 10 software saw both cameras, so I believe they're functioning correctly...

[youngngo]

Did you ever resolve the issue and get the 2nd camera to show up. I have 2 OV2710 attached to a Surface Book 2 directly to 2 USB port and the 2nd one does not registered/recognized!

[RFreund]

Anyone see any issues with these cameras and the setup described in this thread?

[inorkuo]

i don't know anything about those cameras but you could post them in the kinovea forum and joan, the developer ,should be able to tell you if they will work.

[htdumps]

inorkuo any chance that you could make a script for the new version of kinovea for single camera recording and playback in kinovea?

[inorkuo]

i can but i've discovered that the way the experimental version of works is not good for swing analysis. the live delay feature allows you to allocate more memory to get more delay but it drops frames. so even if your camera is capable of 120fps, you might only see 50 frames.

[htdumps]

Didn't know that. Thank man. I wish I can buy you a beer.

[FaultyClubs]

It's not just the window, there doesn't seem to be room for the follow-through without hitting the screen. What are the room dimensions? I'm wondering if you'd be better off hitting towards the other wall?

[htdumps]

Room is 13'x12' super tight.

[aja]

Camera works well, but yeah the room dimensions seem to be affecting the swing. Follow through is pretty truncated, the arms aren't "flowing" through at the end of the swing.

Hello - New to the thread here. I've tried to set up Inorkuo's script, and think I've followed all of the necessary steps. However, when I try to run it I get the following error message regarding the configuration of the recording_dual_main script.



I'd appreciate any advice/help to get this working. As for my system, I am running a Windows 10, 64bit PC with a two monitor display. I have two Logitech Brio webcams configured correctly in the stable release of Kinovea (one at 120fps, the other at 90fps for some unknown reason). Kinovea has not problem with manually capturing from both simultaneously.

I just finished building my simulator, using Skytrak (and running TGC without difficulty). I'm pretty happy with everything, and this is the last step in getting it up an running the way I'd like (at least for now).



Thanks so much for any advice on how to get the audio triggered, dual camera, capture script working.

[inorkuo]

Are you running the exe or the au3 file?

[FredR]

Hi - I am running the au3 file. If I try to execute the .exe file, I get a different error: "Line 13200 Error: Can not redeclare a constant." Thanks so much for your help. - Fred R

[FredR]

Thanks so much, inorkuo! You were incredibly helpful in getting my audio-triggered dual camera capture working. I really appreciate it.

[NovaGolfer]

Hi all, I am struggling getting this to work. I have the cameras hooked up and functioning, 32 bit version of VLC, proper version of Kinova. When the script triggers I see VLC close, Kinova gets the focus and a couple of seconds go by and I get the error in the attached jpeg. I have included by parameters on the screen shot. Thanks in advance for any help!

Sean

Edit - better pictures added, I am running widows 10,

[inorkuo]

In kinovea, manually create a video recording with each recording window so that your file names have hyphens, then try again.

[NovaGolfer]

That did the trick! Thanks for your help and for putting this together and sharing with everyone!!

[Skillz]

I am having a similar problem. VLC is closing once the script is triggered by me hitting the ball.

The rest of the script is working perfectly. The video records and saves in the correct folder, and I can manually replay the video on VLC. But would like the automatic popup to replay the video.

Any ideas on why the script would close VLC and not replay the video automatically?

Also, I am running just one camera currently not sure if that would impact it.
