Performance bad on own video?

[dragen1860]

Dear authors:
Thanks for sharing this fancy idea work, it looks really novel and effective! But when i try to test it on my own video, such as several people meeting video in a room, I found it performs badly. I guess it may due to the relatively small face and not-so-clear sound recorded.
But when i try another good-quality video:

ao_nrsn5djb.mp4

It looks still not-so-good, especially compared with the demo video publish by you. I wonder is there any difference to run the code? or any one come across the same situation??? Thank you.

You can try segmenting the video with a shot boundary detector first.
