About Key Frames

[grannycola]

Hello,

I have a question regarding the key frames in the dataset or the model. Could you please clarify what exactly defines a key frame? Is it the first frame in a clip (sequence of frames), or is it the frame that is located in the middle of the clip?

Additionally, I would like to know if the bounding boxes and keypoints are provided only for the key frame, or are they also specified for other frames in the clip?

Thank you for your help!

It's the middle frame in a clip. The annotations are only for the keyframes.
