Hi guys, I'm doing some video editing and I have an issue. When I apply some effects to a video and rump its speed up, it starts seriously lagging and missinig frames. I have a i5 4670, a GTX 970, 8Gb of RAM and a 2Tb Seagate SSHD. Which of these is weak point? I think the hard drive is slowing me down, but I can see that my CPU is also working a lot when I play back the video. What do you think is my problem?
