Questions on calculating FVD, FID and IS scores

[txchen-USTC]

When calculating FVD, FID and IS scores, how many fake videos (sample.mp4 ) need to be generated? Whether you use all real video frames when calculating these scores?

CUDA_VISIBLE_DEVICES=gpu_id python ./src/scripts/calc_metrics_for_dataset.py
--fake_data_path /path/to/video/frames
--real_data_path /path/to/dataset/frames

Look forward to your reply.

Hi @txchen-USTC!

Thank you for your interest in our work!

For the metric calculations, we used a sample of 1,024 videos, analyzing all original frames from these real video sequences."
