Video summary not getting dumped for some videos in TVSum & Summe at higher SR

[amantanejams]

While running inference on TVSum and Summe datasets(while using the pretrained Summe-trained and tvsum-trained models respectively, provided by the authors), at higher Sampling rates(sr), for some of the videos, I am getting blank output video files as dumps(258 byte video file dumped). It seems that the "pred_summ" variable has all "False".
Does that mean that there are no summary candidate frames produced by the model for that particular video at that sr ? Also, the only solution is to reduce the sr or any other variable can be changed to enable the summary creation? Note that the length of videos in both datasets is decent i.e. 1 min - 4 mins long.
