Hi,
You can export over-under by doing File > Export video > Side by side, it will first ask for the output file name and after that there is another dialog where you can choose between horizontal or vertical configuration. Same for images. This is new in 2023.1.

I think the auto naming system is too rudimentary for this but we could have counter variables. Thanks for the feedback this gives a good overview of what is required.

Hi,
I'm assuming you are referring to this page in the manual, but I don't see the keyboard shortcut mentioned: https://www.kinovea.org/help/en/observa … rison.html

By default the shortcuts are bound like this:
- F8: moves the videos to the synchronization point.
- F9: toggles superposition on/off.

I'm thinking maybe you want the other video to "catch up" to the first one, without moving them back to the sync point?
Ah I see in the old manual that this action was bound to F9 so that must be it. There is no longer any shortcut for this at this point and F9 toggles superposition. I'll check why it was removed.

I was thinking about this and another way could be to do it in the reverse direction with a "startlist". I think this could be useful for various scenarios. Even during training, since you could make a startlist for the various exercises you are about to do.

Something like this:

1. First you would create or export a CSV file containing the information of the sequence of videos that you are about to capture.
2. This CSV file needs to have column headers, for example it would look like this:

bib,name
2542,Tajay GAYLE
2206,Radek JUŠKA
2983,Marquis DENDY
2550,Carey MCLEOD
2200,Alejandro A. PARADA
2869,Simon EHAMMER
2449,Jeswin ALDRIN
2898,Thobias MONTLER
2410,Miltiadis TENTOGLOU
2552,Wayne PINNOCK
3041,William WILLIAMS
2170,Jianan WANG

3. From the moment this file is loaded, each new capture will consume one line of the file.
4. The column headers would be available to use in the file name templates. For example:

template: "longjump-%datetime_%bib-%name"

expansion: "longjump-20230904-1316_2542-Tajay GAYLE.mp4"

Now each time we record a video it would be saved with the right info directly in the filename.

Some considerations:
- If you record two cameras the file will probably have to be loaded in each screen separately.
- There should be a way to navigate within the list before recording, to fix mis-ordering and spurious recordings.
- It would be good to have the variables visible before the recording, for confirmation and in the context of training it could even be used as a cue to know what you are supposed to do next. At the very least there should be a button next to the filename to toggle between the template and its expansion, then it can be a global option where we show the future filename in big font on top of the capture screen (not part of the recording).

What do you think?

Quick update. I think a first tentative release for version 2023.1 is ready, I'll make a full post tomorrow with links.

I fixed some more bugs and updated the language strings for French, Spanish and Italian. These are the only languages I feel comfortable enough doing this with, but as I added/changed many menus and user interface the other translations generally fell behind. Help is greatly appreciated here -> https://hosted.weblate.org/engage/kinovea/

My code signing certificate expired and in the meantime the requirements have changed so apparently now I'll need to buy a more expensive certificate (+$300/year) plus a piece of hardware in order to sign the binaries, so the first release is not going to be signed. I'll provide the SHA1 hash on twitter for integrity checking, so at least anyone can verify themselves, but Windows will raise some warning messages during the installation.

There is a list of issues and important limitations that I haven't had time to address but I don't want to delay this any further.
