Hello, I have two questions:

in a bach ,How do you load video features of different lengths into a tensor? padding them to a max length? if so, what is the max length?
Does the frame in the paper correspond to a clip of the video in the code , that is, corresponds to a continuous video frame ?

Hi,

TGN samples a video segment (see opt.py, options['sample_len'] = 50) from a given video. If a video is shorter than 50s, pad zeros.
The answer is yes. The 'frame' in the TGN paper usually means a clip feature (C3D/I3D, corresponds to continuous frames).
