Imported Video Freezing

Hey guys, I am a gaming youtuber that uses premiere rush for videos often. I am writing this because i tried to import a 10-15 sec video of me playing one of my favorite games to premiere rush. But when I tried playing the recording back on premiere rush, the video froze. I am not sure if this is a genuine problem or if i am simply doing something wrong. I am not sure of the frame rate of the video but I think it is quite high as the match I was playing in was very action-packed. Thanks^^
