Hi all,

I'm analysing a series of videos, and was wondering if the reference information set in the 1st video can be used in 2nd, 3rd and videos recorded later on.

The camera was fixed in the same position throughout the whole time, but we couldn't keep recording due to the battery lifespan.

If there is any way to share the reference length in one video with others, could you please let me know?

Many thanks.

Hi,
Once you have done the calibration in the first video, you can save the corresponding KVA file from the save menu.
You can then import it to other videos from the "Load Key images data" menu. It will import the calibration.

Optional:
If the camera is completely fixed and you only work with videos from this camera, you can have this calibration file automatically imported on every video you open.
To do this you must rename the KVA to "playback.kva" and store it in the %appdata% directory. (For example : "C:\Users\joan\AppData\Roaming\Kinovea"). To stop using it, delete or rename the file.

Additional notes:
- You can safely delete the line that was used to create the calibration in the first place, it will not kill the calibration.
- It will work for plane calibration as well.
- When importing on a video of different resolution, the calibration is "adapted" to the target file.
