The number of videos to test

I downloaded the file “test_videos_2.7z”. There are 667 videos in the folder but I found in the sample submission file, there is 1333 unique video ids. I think I missed something. Could you point out what I miss?
Thanks.

@XiaokangWang I see only 667 unique video_ids in submission_format_zeros.csv

Hi lopuhin, Thanks for your reply. I made a mistake last night. In fact 1333 is the number of training videos. It was too late last night.
