It is the first time I hear of this. Could you share a sample file please?

Re: EZViz (HIKvision) IP camera problems importing MP4 videos .. (7 replies, posted in Cameras and hardware)
By going through the frames of the video I can see the timestamps and when the video reaches the last frame I can compute the total number of frames and total time that are actually in the video. So in theory this should be enough to fix this kind of files automatically. I'm not sure what's the best way to go about it though.
It could initially leave things as they are and after the first loop, when it realizes the last frame doesn't match the duration, try to fix it.
There could be a explicit "Fix duration" button in the Video > Configure timing dialog, that would perform the test and save the actual duration somewhere. This could then become an option in the main preferences to "always try to fix duration", but would be off by default because it will slow down opening the files in the normal case.
Other ideas are welcomed.

Re: Automatic Bike Fit Tracking (4 replies, posted in Bug reports)
The color itself not so much. But it's best if the marker contrasts well against the background. It should also be "rotationally invariant" and if it has contrast itself it's also better. So for example a black disc with a white dot in the middle or vice versa. Otherwise a simple black or white disc should work well enough.

great thanks...generally the replay is once and delete...just for feedback to the golfer for practice. Sometimes that golfer is me...to check my swing etc.
If you are sure you won't save the sequence, the simplest way to do instant feedback is to use the delay function. For example you can set the delay to 5 seconds.

The lines on the capture screen are not the same when I replay the capture.
I'm trying to reproduce the problem. Could you send a screenshot at joan at kinovea dot org? In particular what is the camera image size, whether the camera view is filling the capture screen, and same for the playback side.

Re: Persistence from 8.25 (1 replies, posted in Ideas and feature requests)
This should work as expected now in version 0.9.2. The drawing will be visible while tracked and fade out afterwards. The custom visibility settings can also be used to deviate from this default.

Re: Dual playback screen bug in ver. 0.8.27 (4 replies, posted in Bug reports)
This issue of corrupted alignment in dual save is fixed as of version 0.9.1. It was related to the total size of the composite video adding up to something not a multiple of 4 pixels, this is not always supported by the output format.

This scenario is supported now in version 0.9.2.
After copying and then pasting the image in the second screen, right click and Visibility > Custom fading, then lower the "Maximum opacity (%)" field to make it more transparent.

Re: Delete tracking lines in part of a video (3 replies, posted in Bug reports)
This was addressed in version 0.9.2. The drawings are now opaque whenever they are tracked and they fade in/out around the tracked section(s). You can use the custom visibility options to change the maximum amount of opacity and the fading ramp.

Re: Automatic Bike Fit Tracking (4 replies, posted in Bug reports)
There are adjustments but they are a bit hidden, you need to go to Options > Preferences > Drawings > Tracking. There you will find the default options for the size of the object window and the search window.
The object window should be as small as possible around the marker to avoid picking up the background. The search window should be large enough to encompass the marker's motion from one frame to the other, but not too large that it may pick up another marker.
One way to find the best settings for these values is to start with a normal trajectory tool (right click > Track path), and then go to its configuration window and adjust the values visually from there and do some trial and error to see what works best. Then you can copy the settings over to the main preference window.
It's probable that you will still have to adjust the position manually once in a while.

Re: Cannot see two USB cameras at the same time (8 replies, posted in Bug reports)
(The following is for version 0.9.2)
When you add a line or other object you can right click it and select the menu Visibility > Always visible. This way it will stop fading out after a few frames.
If you are only interested in having lines that are always visible, you can go to Options > Preferences > Drawings > Opacity > Default opacity of new drawings and check the box saying "Visible for the entire video". Now new drawings will be always visible by default, although you can still customize the fading option on a per-drawing basis by going to each drawing visibility menu.
If you are interested in having a specific set of lines to appear every time you open a video, you could create these lines, save them in a KVA file through File > Save > Save only the annotations, and then save this file as "playback.kva" and copy it in the application data directory. This directory can be found from menu Help > Open log folder. This way every video will load the KVA annotation file upon opening.
edit: I forgot to mention, and this is new in version 0.9.2, if you add the line directly in the capture screen, a KVA file should be saved automatically when you capture the sequence, and will be reloaded when you replay it. In this case the objects added at capture time should already be in "Always visible" mode.
Also if you are interested in these capture-replay scenarios there is also a way to automate the capture/playback loop so you don't have to attend the computer each time. This is done using File > Open replay folder observer and point it to your capture target folder.
