Need a bit more info to help you troubleshoot. 1- What version of Windows are you using? Window’s 10 2- What Graphics card (GPU) are you using? Are drivers up to date? NVIDIA GeForce GTX 1070Ti 8GB GDDR5, Yes 3- What type of media are you using in your sequence? (Codec) Either, mp4, mts mov. The error happens when it’s all in one version, Or if we have to do it mix, we’ll format so they’re identical, or make sure they play nice with each other 4- Does the media in your example play back in VLC or any other media player? Yes it works on VLC 5)- Is the media on your local drive, external drive, shared network storage? Mostly Local drive, there may be some projects are on shared, but try to pull shared In local drive 6)- Have you installed the latest versions of the beta apps since they update daily / weekly? I only saw the 15.0 Beta Premiere Pro to download and said I’m up to date 7) - Have you created a completely new project from scratch and imported the same media to see if it plays? Correct I have and still have the problem 8) - Have you tried uninstalling the beta software, reinstalling, rebooting and trying a new project? Correct I have and still have the problem 9- Does the same media playback without issue in the shipping public version of Premiere (v14.9)? Correct I show the same problem In 14.9, when I update to 15.0 I still have the same program. 10 - One last thing to check, change your Program monitor resolution to Full , your example video shows it at 1/2. Under the wrench menu in the Program Monitor check if High Quality Playback and Transmit are cheked. Ok I have set it to Full, checked HQ playback and see transmit are checked, and still show the problem Hopefully answering some of these questions a solution can be figured out and get you back up and running. I"m still showing the same problem, but in my earlier comment with Kevin had recommend a ZOOM call, and still get the sense that may be the next step if the answers I provide does not help us figure what's going on?
