My arrow keys aren't going frame by frame
I've been using Adobe Premiere for years, and hitting the arrow keys have always meant moving one frame at a time. Now, though, it seems to have suddenly switched to moving 0.00001 seconds along the timeline (same with holding K and using J and L). Obviously, this doesn't make any progress at all. The audio time units on each side of the video are way too precise by about three digits. Does anyone have any idea how to change the arrow keys back to scrolling frame by frame?
