Convert kinetics datasets (or other video datasets) to frames. Support resizing and temporal sampling for space efficiency.
- OpenCV
- progressbar2
python convert.py --in_path [path_to_kinetics_root] --out_path [output_path] -n [number_of_processes] --min_size [Length of the minimum side, -1 to disable resizing] --sample_rate [temporal sampling rate]
Use python weed.py --path [output_path] --remove to remove empty folders.
Converting Kinetics 700 to frames with the default setting yields a dataset that is only slightly (10%?) larger than the original video format.
Good to know.
You can download the Kinetics 700 dataset here: https://github.com/cvdfoundation/kinetics-dataset. Oh my god I love them.
