Error computing optimal fov

Trying to stablilyzed insta360 go 2 video with default settings< and get the following error (trying with different files< the same result):

Same here. GO2 on Windows 10.

hmm. Could you provide the files that gave the error?

Just tried one of the clips and it renders for me with Insta360/Insta360_Go2_2880x2880_ProMode_unprocessed.json on the current dev branch, so not sure what was causing the error. Setting the render in/out points to see if that helps.

Note that the gyro orientation might still be messed up since there isn't one specially for the go2. Maybe someone could record a handheld clip with some standalone roll pitch yaw movements?

Here is a sample video from the go2 in pro video mode: https://mega.nz/file/Es8ETLIT#1xY1aFHIPwL1Y2IUWajIAq6WLt24_yj7cjU2_50Epjg

Trying dev branch with settins You've mentioned. Works fine, optimal fov calculating error does not appear. Seems the problem was somehow fixed
