For some reason I don't know, my main project timecode all of a sudden went from 8 digits to 9, which makes quick editing really annoying for me. How do I change it back to 8 digits? The image shows what I mean, the top one being what I don't want, and the one under it being what I do want:
So you understand what is going on, first, right-click the timecode in the timeline. You have "milliseconds" selected. Or you could pick Audio Samples. You see this because you have accidentally set the time to "Audio" time units.
To fix it, in the top of the timeline, left-click the hamburger menu (3 lines) for the sequence you have selected. Uncheck "Show Audio Time Units."
Easy to do accidentally; almost impossible to figure out what happened!
