kinetics-downloader

Simple tool to download videos from kinetics dataset.

Also have functionality to trim downloaded videos to the length of action. To support trimming, ffmpeg should be installed and added to environment variable PATH.

Usage

Install requirements first

pip install -r requirements.txt

Known bug

In Pytube there is currently a bug where some videos do not have a streams list, fix this by using the latest version:

python -m pip install git+https://github.com/nficano/pytube

You should download and unzip csv files with links to videos. You can download such files here. For example here is link to kinetics-600 training.zip

Downloading

cd kinetics-downloader
python download.py /path/to/kinetic_train.csv /path/to/videos/

Downloading and trimming

cd kinetics-downloader
python download.py /path/to/kinetic_train.csv /path/to/videos/ --trim

Parallel processing

One can run downloading and trimming in several processes. To do so, just add flag --num-jobs with number of jobs running in parallel. For example:

cd kinetics-downloader
python download.py /path/to/kinetic_train.csv /path/to/videos/ --trim --num-jobs 10
