No cameras listed in camera menu

Hello,
I just downloaded the actionstitch software, I downloaded the sample videos but I can’t use the sync button as I can’t select a camera.
Can you help please

The camera list should be automatically retrieved from https://actionstitch.com/get_camera_data. Can you check the log file to see if there is any error message? On Windows the log file is C:\Users\<username>\AppData\Local\actionstitch.com\ActionStitch\actionstitch.log. On macOS, the log file is /Users/<username>/Library/Application Support/actionstitch.com/ActionStitch/actionstitch.log.

Thanks for the reply,
I tried installing on my work laptop as it’s more powerful and I think my proxy server was blocking the list.
I installed on my home pc and the list is there.
I done a conversion of the example files and tried playing it in VLC and it was very glitchy and unwatchable.
Is there anything I could do for this?
Also I have 2 GoPro 5 blacks, these aren’t in the camera list but I can record at 4k so will have to try them.
Regards

VLC can’t play videos with such a high resolution. You can use my open-source in-browser video player for ActionStitch videos: https://github.com/gilbertchen/actionstitch-player

You just need to take a video of a checkerboard like this: https://download.actionstitch.com/calibration_sample.mp4 and send the video to me.

For the checkerboard I would suggest printing the A2 25mm one from Calibration Checkerboard Collection | Mark Hedley Jones. A a 18"x24" blue print at Staples would costs only $1.89.
