How to use exported JSON video annotations from LabelBox?

šŸ¤ Community Help
1

Iā€™ve got JSON exported from LabelBox representing annotations of a video. LabelBox doesnā€™t know how to export their own annotations in a format that can be used by YOLO or anything else (ā€¦) so Iā€™m hoping to use Roboflow to get it to YOLO format.

When I create a project Roboflowā€™s ā€œuploadā€ tool accepts the JSON file, then it asks if I want to download images from LabelBox or upload them. Regardless of which I choose, nothing happens afterwards. Thereā€™s nothing on screen or anywhere in the project indicating that anything has been uploaded / added.

I tried uploading the video first. It generated images from the video, but I donā€™t see a way to add the annotations to it.

Hi @Jason_Miller

Sorry to hear youā€™re having issues. Could you look in the developer console (F12) and see if any errors show?

Also, only if you are comfortable with it, could you share your JSON file so that I could try to reproduce and troubleshoot the issue?

I am still having the same problem, how did you solve it?

Hi @yf_bbb!

I am sorry you are encountering this issue. Do you mind providing a screenshot with your developer consoler opened to see if any errors are showing?

To further help me troubleshoot, were the annotations completed using the Roboflow platform or LabelBox?

Thank you!

Hi @yf_bbb!
The best way to handle this is to visit roboflow.com/formats and ask ChatGPT to write a script that converts your format to COCO JSON.

You can then upload the frames via the Upload flow.

I reached the same conclusion and was able to transfer it to Roboflow by converting it to either COCO or YOLO format. Thank you!
