Thank you for your pull request. However, it should be significantly revised before merging.
I'd be more positive about it if:
- one pull request wouldn't implement two features: one for the ten crop, the other for the changes in disk writing
- I don't like that each crop is treated as a separate video (now each video creates 10/5 times more files. can't we implement crop as a batch dimension?
- the augs are applied only to RGB stream, not both.
- the augs are implemented for i3d but not other models.
- i am not happy that the classes/functions that are common for many models are being changed without reflecting on how logic for other features that depend on them changes
i appreciate the efforts but i am not convinced that it is enough

any reason why we can't do it for the flow?

Why treat each crop as a separate tensor instead of a batch dimension: B, Crops, D --> B*Crops, D?

we shouldn't resort to this. it became incredibly redundant. we need to save all features in one file

what's wrong with the streams argument in i3d?

Add ten/five crop augmentation when extract the I3D features. Solve issue #92 #72 . And add save_option to the i3d.yaml file to save only reg features. Because I think that fps and timestamp features are really redundant. The shape of the rgb features imply timestamp.
Thank you for your great work. 🚀🚀
