Hi and thanks for interest.
You can't do that.
That's because this architecture is tailored to take as input 16-frames clips.
Theoretically (i.e. with infinite gpu memory) you could compute features for such input shapes up to pool5. After that, the reshape at line 59 of C3D_model.py would result in a different dimension w.r.t. the subsequent linear layer, causing an error.
A common practice in those cases is to compute descriptors for 16-frames clips. In your case that would result in 1748-16 descriptors. But it depends on your application.
Hope this helps,

Thank you for your feedback.
Just to summarize, what you are trying to say is that the model is trained to input 16 sequential frames and computes its corresponding features for these 16 frames. This would be computed for
total frames / 16 times?
Hope this is correct?

Precisely.

It depends on what you feed to the model. If you build 16 frames clip striding one frame at a time (x_0 to x_15, x_1 to x_16 and so on) it would result in total_frames - 16 descriptors. But again, it depends on you and what you want to do with such descriptors.
