Hello
I was able to wirelessly easily connect my smartphone as a webcam by using this software. Seems like a fast developing option. Small problem is the YUY2-format eating bandwidth and limiting the resolution.
I did not yet try connecting with wire...

Topic: Connecting the zoom-function (0 replies, posted in Ideas and feature requests)
Would it be possible to link the zoom-function in a double-view?
Superimposing two videos or images, zooming in and toggling between frames/images would make it much easier to find changes visually.
Linking the movement of the two frames/images would also be great

Topic: Connecting the distance grid planes? (0 replies, posted in Ideas and feature requests)
When using multiple cameras - would it be possible to connect the distance measurement grid tool over several grids - moving the line in one image would also move it in another?
As for now, the average precision of a pixel (mm/px) decreases towards the far. Using opposite cameras, calibrated in their own perspectives, could solve this and also help in situations when an uneven 3D surface gives a "false" measure in 2D.

Re: Camera for recording video (1 replies, posted in Cameras and hardware)
Of course you can use your laptop camera, but as it is facing yourself, it will be very difficult to handle the controls....?
The price for a decent webcams has dropped significantly. I use a Streamplify webcam that gives FHD 1920x1080 at 60fps, for a price of 60 euros.

As I do not own any iOS-systems, I am asking if any of you, Kinovea-users have tried this windows-emulator to run our great program under iOS?

Re: Naming to external list? (9 replies, posted in Ideas and feature requests)
For the time being, the best option would be using the automatic"naming"-function
Example:
Name of competition_ Round A_ Jump 3 etc.
...
MenU20 A 3
MenU20 A 4
MenU20 A 5
...
MenU20 B 2
MenU20 B 3
...
last three rounds
...
MenU20 D 2
...
etc.
If needed, these named videos can be found by checking/comparing to the protocol.
This needs the possibility to have TWO increasing listings in the naming by a defined amount A-G - a round- AND jumporder, number of competitors - including a fast tab to either increase or decrease this number?

Re: Naming to external list? (9 replies, posted in Ideas and feature requests)
I will try this.
Then we need a way to easily "shut out" jumpers that decide to retreat from the competition, leave out jumps etc.
In competitions with more than eight participants, there is also the "problem" with changing the jumping order after three rounds.
thank you for your work, Joan.

Re: Maximizing the resolution of a photo? (2 replies, posted in General)
Would it be a tough thing to make it possible to take photos independently, by using a 2 or 4K camera?

If the camera is capable of 2, 4K or higher, is it possible to take the photo in higher resolution than the video FHD?
p.s.
ShiftN is a free program that does great, automatic correction of lens distortion.

I have used a Streamplify webcam. It gives me 7-9 pictures of the contact on the board...true 54fps at FHD and works right out of the box.

Would it be possible to either link or copy the list of captured files in a defined session to an external txt-file or a spreadsheet?
This would make it much easier to combine the protocol of a competition with the recorded clips.
p.s. Kinovea was used in womens triplejump at the IAAF Tampere Indoor Meeting 9.2.2023. Worked great!

@AlexanderH
There is a new video in the onedrive directory (see previous post) that may fit your need.
It identifies the bib number AND the jumper for confidence reason
Yes,
that is the idea I´m looking for. The quality has to be a bit higher, though
Heike was a fantastic athlete!

There might be a solution of using automatically post processing the recorded videos from both cams.
First there are some questions to clarify:
1. What type of information you would like to give to the jury, an (one) image or a video
2. At which time the judges will take a look on the result, just after the jump or do they scan the jumpers afterwards one by one
3. For what do you need to capture the image at the time of the jump? To see the bib number or to see the take-off?
4. How do you start the recording, manually or using a trigger at a given moment?
5. What is the resolution of both cameras in use?
6. Do you use the same framerate on both cameras and how high is it?As Joan already mentions, the mode of recording in principal does not influence the framerate but may be related to the system bandwidth.
It might be better to use the retroactive-mode, it gives a more stable video-streaming due to exclusively working in the computer memory without disk access interference. To my personal experience it is even more stable to use separate instances for each camera and not to use the dual recording mode in one single instance. Comparing both methods on my computer it has been shown that the total cpu-load rather is smaller if one Kinovea-instance controls one camera, compared to the dual recording mode.A technical more simple solution would be to create a horizontal side-by-side video of the whole jump, using the 1. cam on the left side as the leading video that controls fps, video resolution and image quality, padding the 2. cam to the right side.
1. I would like the bib of the jumper to be automatically inserted into the takeoff video.
2. The judges/jury should as soon as possible be able to review the moment (a snapshot) where the judge of the event deems it unvalid. The jump will be measured, but under protest until this final decision. Could be needed before the three final rounds.
3. Both. I need a picture of the bib, 1-2s before takeoff to be inserted in the takeoff vid.
4. I start the recording manually at the takeoff with -1s delay to stop at 2s. I want a picture of the bib to be taken from the run-up 1-2s before takeoff.
5./6. The webcam on the board is recording in FHD 60fps and the webcam to the run-up is HD/VGA, 10-25 fps (but a snapshot would be enough)

Re: Joint control option? (15 replies, posted in Ideas and feature requests)
Yes exactly !
Streaming the two webcams in delayed mode seems to drop the framrate (50-60fps needed)? Or am I misunderstanding this?
p.s. we are checking out the Kinovea-system for long jumps at the training camp competition for the Finnish national team on Friday...

Re: Joint control option? (15 replies, posted in Ideas and feature requests)
Yes, but I need a way of catching the picture at the time of the jump. Hence the second cam to take snapshot of the incoming jumper. The picture and video can then be combined from their respective auto replay folders in an other running instance of Kinovea?
This would be needed as automated as possible, so that any materials can be handed to the judges/jury for checking without searching in that mountain of files...
One click at the board-> the automated jump video 1s delay+2s autostop and a picture with 2-3s delay
