Question about frame number of training video.

Thank you for this great work!

I found that in training stage, the frame number of every videos (frame groups) are random. I wonder if this variable length training strategy is better than the fixed length training strategy.

The pseudo code of fore-mentioned fixed length training strategy is shown below.

for i in range(epoch):
    for scene in scene_list:  # In NuScenes dataset, frame length of every scenes are approximately equal (around 40).
        for frame in frame_list:
            ....
            train(data[scene][frame])
            ....
