Thanks for your answer. I had this problem yesterday but my post could not be approved because my name was not showing in full….so I also asked elsewhere.
As you said, they were in a secondary storyline.
I right clicked on those clips and chose “lift from storyline” and then deleted the black box left by those clips. They went back where they were supposed to be.
Before asking in forums, I was trying to fix it myself but because I was clicking on the grey box on top of those clips, to highlight them, when right clicking, nothing would show up to make any change. Instead I should have highlighted each clip on its own and then right click and lift from storyline!
I detached the audio from the video clips because I wanted to add a few effects and in a few video tutorials they say to detach and then compound the audio so the changes will be applied to the full audio.
I never do compound clips usually for the type of videos I make but I was done with the editing and so I did a compound clip for the effects.
Once you do apply your effects, is it possible to reattach the audio to the video clips?
Any advice or tips are very much welcomed and thanks again for the answer!!!
