Yeah, a very similar work flow. I’m using a CNN + LSTM architecture with this kind of file structure. This dataloder does get me frames in sequence, but my doubt was, as I explained what if I’ve some 33 frames and my sequence length is 10. This sequence length yields me three sets of 10 frames each, but the last three frames are they discarded or repeated?
Also can you please point me towards some more detailed and up to date explanation of the sampler.
