Clipping a short video (mp4) from my phone in PD365, produced with the audio muted, and get a black screen. If I unmute the audio it produces fine. I did it three times with the same result.

EDITED: Okay, so if I take the video I produced with audio, and then mute that one, it produces fine. So it must be something with the cell phone video? It's not an issue now since I was able to do it, but I would like to know for future use if anyone has any thoughts.

You might try pref > Hardware Acceleration and uncheck the hardware decode option and see if that helps.

This worked! But do you have any idea why muting the audio would cause a problem?

I know of no logical reason. There have been a lot of bugs in PD through the years with hardware decoding and encoding that never really get resolved. The features are great when they work and I use them often, the implementation in PD has shown it's just not very robust.
