about the new length and the num_segments

[CDLCHOI]

I don't understand exactly about the new_length and num_segments。

I download the "112_c3d_resnet_18_kinetics.caffemodel" and remove the FC layers。
And I use the model without FC layer to finetune UCF101 ：
if new_length=16, num_segments=1, the top1 got 83%;
and new_length=1 , num_segments=16, the top1 only 78%;

I saw in TSNg github that ：new_length=1 ,num_segment=3 may means averagely split the video into 3 segment and take 1 frame from each segment。
How about new_length=16, num_segments=1 ？

It is the same with TSN code.

It is the same with TSN code.

yeah,I now it is same with TSN code,
but TSN use "num_segment=3, new_length=1";
the ARTNet use "num_segments=1 , new_length=16"

can you explain its meaning? I don't understand it
