How to store flow and rgb images of Video Dataset on disk under prescribed inode limit

I am working on video understanding for which I need to store video datasets such as UCF101, HMDB on the server. My server has an inode limit for each user say L number of files.
If I store the RGB images and flow images of UCF-101; it overshoots the limit. I want to know if there is a better way to store these RGB images and flow images and process these during video training so that I don’t overshoot the inode limit.
Have anyone faced this issue ?
