Hello everyone. I've been having some intermittent issues when editing video. Some times when I record my computer screen or my smart phone for a tutorial video, when trying to edit it, the video is very slow. It feels that the 60 FPS videos that I make get change to like 10 FPS. The weird part is that when playing the video in with other video apps, the speeds is normal. All videos are recorded in MP4. Have in mind that this issue doesn't happen all the time.
Any help in the matter would be really appreciated.

Thank you.
