What do Pair, L, T stand for in the code?

Hi, I'm a beginner and would like to ask a question. What do Pair, L, T stand for in the code? What do they mean?

# Pair x L x T x 3 x H x W
video = np.zeros((len(s), self.max_frames, 1,
                  3, self.rawVideoExtractor.size, self.rawVideoExtractor.size), dtype=np.float)

As far as I understand:

• Pair: number of samples (videos)
• L: length of video in frames
• T: time axis? It's always 1 rendering it practically unnecessary...
• 3: RGB channels
• H: height
• W: width

Happy to hear thoughts of other members who have been using this repo!

T is a scalar representing a set of frames extracted from the same one-second-interval. With an fps of 30, each group of 30 frames will share the same T value. I guess that this will play a role in the frame extraction strategy.
