Clips from one source on timeline, some visible in timeline and source window, some not

[Maluhia2U]

Premiere Pro 2023 CC 

iMac running Montery 12.3.1

I have 3 camera sources,  3 video tracks. 1 audio, 1 music. 1:49 long.

The problem is only one source file. I used several clips from it and some play totally fine and then the rest are not visible on the program window or souce window. However, the clips still show on the timeline. I have dumped the media cache, restarted Premiere and replaced the media. 

Ideas and fixes are greatly appreciated as I have been trying to trouble shoot and find fixes on line for awhile now.

Try resetting the preferences:

If that doesn't work, try resetting the Workspaces:
Reset a workspace
Reset the current workspace to return to its original, saved layout of panels.
1. Do one of the following:
• Click the Workspace menu icon and select Reset to Saved Layout.
• Choose Window > Workspace > Reset to Saved Layout.
from here:

If that doesn't work, try Preferences > Audio Hardware and set Input to None.

If that doesn’t work, try updating or rolling back your graphics driver directly from the video card manufacturer’s site. If NVIDIA, do a clean installation of the latest Studio Driver (NOT the Game Driver).

If that doesn't work, try creating a new project and import the old one into it.

starting a new project and importing worked!

If that's not it, please use the free MediaInfo and post a screenshot of the properties of your media in tree view:

Many users are having issues with VFR. If the file is variable frame rate, use Handbrake to convert to constant frame rate before importing into Premiere Pro:

Here is a tutorial:

Shutter Encoder may also be used to convert to Constant Frame Rate:

Thank you! I will dive into these tomorrow, this has all fried my brain!

I've moved this from the Using the Community forum (which is the forum for issues using the forums) to the Premiere Pro forum.
