Hi Joan,
Thanks again for a fantastic program! I have used it analyze video of my swimmers, and the other coaches are just blown away. I even passed it on to a nationally known coach (Bob Gillett, who coached Olympia Misty Hyman), and he was also impressed. I am still discovering new features, just bumped up to 8.19. I also have the long awaited GoPro Wifi Bacpac and remote, so I started looking into live streaming possibilities. I find that the Gopro does in fact have live HDMI passthru hardwired, had it all along. I could have done streaming all along! I will try a Roxio Game capture HD Pro to get the HDMI to USB2 to PC. My PC is somewhat old and has Firewire in but no HDMI in.
Another path, thru wireless network is more complicated, but some people seem to have done it, using VLC and connecting it as a network camera. I am going to try that next and will report back.

Since I am doing underwater video of swimmers, I chose the Gopro Hero2 as my primary camera. The wide 170 HD mode lets me catch the entire swimmers body in sideview, from very close in, thus minimizing the impact of water turbidity. I also have a Kodak Playsport which I use for filming from the deck usually.
I am anxiously awaiting the Gopro wifi backpack with streaming output. The h/w is out now, but the s/w is not.

I am not the one to say what can and can't be done with digital technology but here are some basic points to consider relative to motion blur, shutter speed and camera operation.

The motion blur is controlled within the camera by electronics that turn the sensor’s elemental detectors on and off while they are collecting photons. The on-off time is the shutter speed. I doubt that any available cameras such as the FaceVsion Touchcam N1 will allow external software to control the camera’s shutter speed electronics. [In some more basic sensors I'm sure it may be possible.] Please correct.

What is "Video Source"? Does it control cameras?

I see a lot of discussion of cameras with a very wide range of frame rates from 10 fps to 1,000 fps. I'm getting a little disoriented......sports video applications....10fps, etc. ? My Casio Ex FH100 camera is high speed video and does not have an output while recording as far as I know (Eye-Fi transfers after recording I believe??).

For anyone interested only in some very basic high speed video camera issues and requirements for sports I'll open a separate thread.

The properties worked...my eyes didn't :-) Setting the exposure really improved the motion blur.

Another thing that I have tested is the use of DV converter like ADVC55. I have two installed on the same computer (two different firewire interfaces in order to make it work). The video capture really put the computer to its knees.

Thanks for the feedback on this camera.
Try to use the "Properties" button to access the driver's properties page with the extra settings.

Hello, One interesting camera currently on the market is the FaceVsion Touchcam N1. It has some interesting features but most important has hardware compression (H.264) internal in the web cam and uses USB. It can do HD in 9 fps but 640x480 in 30fps which is nice for sports. I have evaluated the camera for use in physical education at the university (Southern Denmark) and it performs quite good. It also works with the latest version 0.8.15. The only thing I am missing in Kinovea 0.8.15 is the option to adjust the exposure. Exposure is important if you want to avoid motion blur in the images. Normally you use the "Video source" (DirectShow programming stuff) to do that. But I dont see the properties for enabling that in kinovea? Only selecting the format. Hope to see it soon :-)

Last: Thanks for a very nice tool. Good work.

I have done a quick test with a couple MiniDV camcorder I have. I have 4 of the same model I've used with a 3D program, but have used 2 for the Kinovea test. They are Canon MiniDV ZR80 series cameras that shot SD video of 4:3 and 16:9 720x480 resolution. These are about 5 years old and I think cost about $299. I think the current version can probably be had for about the same or less. They have firewire connections and I have used 2 pci firewire cards to connect them and on another machine 1 onboard firewire and 1 pci card to record in Kinovea. I have not tested out the 16:9 aspect ratio yet.

I also have a Casio Exilim EX-FH20 camera that shot stills at multiple resolutions and video at 1280x720 and high speed video at lower 4:3 resolutions. I mostly shot 210fps, but it can do 420fps as well. The picture just gets smaller and smaller. The 210 fps plays perfect in Kinovea, the 720p HD video does not, even on my faster Core2Quad system. Is there a way to play the 1280x720 video in Kinovea? This camera has a USB connector and an SD card slot. Currently I record onto the SD Card and copy it to the system manually. I wonder if the would ever be able to use the USB cable to record live video via USB?

I have experimented with a couple of webcams and camcorders. The webcams we've experimented with (logitech Quickcam 4000 pro, Microsoft lifeCam VX 7000, generic OEM webcams) have been adequate in providing usable quality videos. However, they lack the user controls available to camcorders (e.g. optical zoom, image control etc)

We haven't yet been able to buy high end digital camcorders with firewire output. However we've been using analogue camcorders attached to a PVR to capture video and to allow us to create a live-delay and replay video. Now with Kinovea incorporating live-delay we're trying to shift from a analogue to digital system all together.

We've been testing a USB video capture card to import live video into Kinovea.

I agree with others in that it is a very good alternative to buying a new digital camcorder with firewire/usb video output. The USB capture card we're using is Easy CAP DC60+ that was bought for ~10€. Video is streaming in at 720×576 px @ 29 fps (PAL) and the quality is better than our webcams.

We're haven't had any problems so far (~1 month) and I wonder if anyone else has experimented with such a setup.

I have tried the small pocket camcorder Panasonic HM-TA1 and it is not suitable for capture because the webcam mode supports only 640x480 at 10 FPS.

All,

I do very specific coaching/video analysis for US Football kickers/punters and youth soccer players. I used to use a Firewire- but its painful and probably in about 6 months will be ancient.

The video camcorder I have been using is the Panasonic Digital camcorder with 800GB Hard Drive and I got it on sale on-line for 246.00 USD. I then purchased the Haupage USB Live2 Video Capture device (thru Dell) for about $50.00, with very good success.

Regards,

Marc

I have checked the functionality in Dartfish 4.5. There is a configuration window where i can set the video resolution and the framerate. This should be a nice feature, especially when the camera supports a high frame rate like some from Microsoft (60 fps).

I received my Logitech QuickCam Pro 9000 today. It delivers quite good video quality. There is no flickering during recording. It is a very good value for the money as it only cost 50 €.

But there is a problem. I cannot get the best video quality from the camera in Kinovea. The Logitech video settings don't apply to Kinovea. Here are 2 images take from the Logitech software an Kinovea:

Hi Sven and Joan,

The HD cameras have a AV or a S-video out option. Then is a cheap AV-USB converter the best solution.

Another suggestion is to go for the HD-cameras without hard disk (storage on memory card). These have in general an USB out. See for the Toshiba Camileo S20, the Kodak Zi8, or some of the Aiptek models.

I have been watching some videos on youtube about the Logitech QuickCam Pro 9000 and the Microsoft LifeCam Cinema. They both seem to be good webcams and could be suitable for basic purposes in low range.

I wonder how much i need to spend more to get a significant better video quality as the both webcams cost about 60 €.
