Number of annotated samples in a scene


after exploring the dataset I found that there are some scenes like scene-0043 have only 39 annotated samples and some scenes like scene-0042 have 41 annotated samples, while majority of the scenes come with 40 annotated samples.

Can you tell me if I am right in saying this or am I doing something wrong and that each scene has in fact exactly 40 annotated samples?

Thanks and regards,

That’s correct. Since the sensor frequency fluctuates, we sometimes have more or less keyframes in 20s.
