Currently there is no option to default the trigger to "armed" but it can be added, I'll write it down.

Re: Calibration (2 replies, posted in General)
Hi, sorry for the late response.
In general users don't see or use the image based coordinates. The pixel coordinates (when there is no calibration) is aligned to the bottom-left of the pixels, not to their centers.
There are several confounding factors, in particular the way the image is painted on screen with pixel offset and bilinear interpolation. But arithmetic between pixel locations should work the same. Several functions return fractional pixel positions (zooming in, tracking, calibration).
It's hard to describe without making things even more confusing, so I'll post an image. This is a 4x4 image magnified, with the 4 center pixels colored in. I disabled pixel offset and bilinear interpolation (this could be an option if you need this for research). In yellow is Kinovea default coordinate system.
So if your image coordinates start at the top-left of the top-left pixel, then the center is at 2, 2. This is what the KVA file will store in the calibration node. If your image coordinates start at the center of the top-left pixel, then the center is at 1.5, 1.5, which is maybe what you expected.
But as mentioned this is confounded by the rendering options, pixel offset mode will make it so everything is pre-offset by half a pixel, this is relevant when the user selects locations in the image. I'm not saying this is bug-free, but the tracking work done last autumn makes me think there is no issue that would be as large as a half pixel, let me know if you find something problematic.
I think the only moment where this would be relevant is if you have an external system giving you pixel-based coordinates.

Re: I would like to conduct remote training. (1 replies, posted in General)
Are you talking about having a video that you review and you want to share your feedback in live with the student while you both look at the video? I consider this outside the scope of the program, mainly because there are many external software that let you do this easily.
For this you can use anything that let you share your screen or a specific window. Video conferencing applications typically have this, probably the most natural solution in a remote training scenario since you would already be using this to communicate. So Zoom, Google Meet, Teams, etc. should all work, look for their screen sharing feature. Instant messaging apps like Whatsapp or Discord also have this.
Or are you talking about getting the live feed of the student while they are doing an exercise, and you receive their video stream as fast as possible so you can give them feedback in near real time? Where it's the student that's doing the broadcasting? Maybe by saving the files on an online drive.

No, right now there is no way to snap the time of the cells to match key images.

There is not really any mechanism to load CSV files at the moment but it could be done. What does the data contain?

Re: python 3.13 call to: "Kinovea:DualCapture.ToggleRecording" (2 replies, posted in General)
Hi,
Unfortunately there is a bug with dual recording commands in the released version. The ones for single capture screen should work, can you confirm that? This script seems massively useful.
I fixed the issue in the source code a while back but haven't made progress on the other things I wanted to include in the next release.

Yes, the program still doesn't support sound at the moment.

Re: Crash when having too many keyframes / annotations. User handle limit (4 replies, posted in Bug reports)
When opening a new file it limits the number of thumbnails created to a small number to avoid it taking too long and only creates the thumbnails later when navigating to them.

Re: Photosequence Export of Custom Key Image (3 replies, posted in General)
Hi, yes it's possible. You need version 2024.1 and then you use ALT key + scroll backward or forward with the mouse wheel while hovering above the cell. This will change the time reference of the cell.
I added some documentation here: https://www.kinovea.org/en/forum/viewtopic.php?id=1973
It won't automatically import the key images you have previously selected. It's an independent process, you'll have to configure the kinogram for say, 5x1 cells first, and then move each cell in time to find the right spot.

Re: Crash when having too many keyframes / annotations. User handle limit (4 replies, posted in Bug reports)
Sorry about the crash. I think it's likely related to the thumbnails that are created for each key frame, both in the bottom area and the side area. Not sure what the best solution is to address this.

Is there a possibility that this will be enhanced/fixed in the future to allow for 2 of the same FLIR cameras to work? Or is this just a permanent shortcoming of the driver(s)?
Yes it should be fixable.

No, RTSP is not supported at this time.
See if the camera has an MJPEG stream, this is the protocol that is supported.

Re: 2024.1 crash when exporting XSLX (3 replies, posted in Bug reports)
Thanks.
I know about this crash unfortunately at the moment I don't have a solution. I'm tracking the bug here: https://github.com/Kinovea/Kinovea/issues/165
It's an incompatibility between two external dependencies… unfortunately it's not looking good so far.

Re: Failure:unable to open the file: file not found or empty (3 replies, posted in Bug reports)
Hi, unfortunately I think you are hitting the bug where file names with Korean characters fail to load. There is no fix at this moment, a work around is to rename the files to use Latin characters, sorry.
