Calibration Transfer IndexError

Hello, When I try to transfer a calibration from one video to another as explained in your youtube video I get the error:

player - [ERROR] launchables.player: Process Player crashed with trace:

World video sources for these two videos are different and they are taken by a DIY headset. I would be glad if you could help me. Thank you.

@acarayberk The issue is that the program does not recognize the calibration as "from another recording". To do that, it compares the recording uuid saved in the calibration file and in the recording's info.player.json. Did you copy the latter file, too?

[acarayberk]

Thank you for your answer, I copied calibration folder and info.player.json file but the error persists

Let me clarify, the info.player.json file must not be copied. To fix this issue:

1. Delete the existing calibration files
2. Open the info.player.json files from both recordings. Ensure the recording_uuid field is different for the two recordings
3. Open Player and the first recording.
4. Create a new calibration
5. Copy only the calibration file to the second recording, no other files
6. Open the second recording
7. The calibration should be displayed correctly as a calibration from a different recording

Thank you very much, that solved the issue.
