Getting wrong results for queries irrelavant to the video

Coronal-Halo opened this issue · comments

Hi, this is great work, but I do find some problems when using this model.

When I give a text query to query something that does not exist at all in the video (e.g., when I ask "driving a car" on a video about a girl reading a book without any car), the model will always give a time frame that is completely irrelevant to the query. How can I solve this problem and make the model not output anything if the query is completely irrelavant to the video?
