About uploading video annotation

I have a question about uploading video annotation.

When uploading annotation data to labelbox, I think it needs to be converted to ndjson format like below in advance.

I have a question about the key name “frame” in this, is it correct that the start of this number is 1?

If I set the frame number to 0 this time, that annotation information was not uploaded(No error occurred).

Please let me know about this one! Thank you.

Hi @IkumaUchida, you are correct that the starting frame number is 1, which aligns with how the frames are numbered in the video editor.
