Adobe and Premier Community, I have a project that was ongoing for over a year with dozens of separate sequence videos in it for this website client. In each sequence we have numerous nested clips because we change the speed on the clips and then sometimes apply Warped Stabilizer, thus the clips need to be nested to do this. None of the footage or editing has changed since completing this project back in April (It was 100% perfect in this last version of Premier), but now the client wants to edit a few of the videos with new building stats. No problem right, WRONG! Much to my dismay, I now have the "danger stripes" blue diagonal line issue with dozens of clips and nested clips throughout my project sequences that I have to go through and manually fix to what was once a finished video. WHY??? This project was perfectly edited to their request and all videos were exported to H264 for Vimeo upload. I thankfully have them all to use for re-editing each mistake that Premier caused! Since the project was finished in April, Premier has been updated 1-2 times and thus the project needed to be updated to the latest version when I opened it in the new version on my system. I have never had an issue upgrading this project or any in the past. This update caused this diagonal line issue throughout my already finished project on EVERY timeline in numerous spots. This is going to cost me days of non-billable time. AHHHH!!! This appears to mainly happen on all the nested clips, but it also happened on a few regular clips too. Some nested sequences are fully black, yet still show the clip it's linked to properly in light blue. Yet some show the footage for half the clip and diagonal lines through the other half, thus turning black for that half. The reason for half and half is the linking of the nested clip is there, but the clip linked is only showing what was marked in to out. It does not show the entire master clip it was originally pulled from. Or, in some cases, it shows the wrong in to out location from when it was edited. Why would updating my project cause this issue and change 50-60% of my nested clips and 20% of the regular clips to the wrong in-out and thus give me diagonal lines on the clip? ALL of the clips with the glitch are shot on GoPro Hero 5, have the Gopro Lens correction filter applied and some also have Warp Stabilizer applied if that matters at all to the discussion. I am still scanning through each timeline, but it appears that all drone footage and graphics are 100% correct. Here is a Dropbox folder full of images showing the issue across numerous sequences. https://www.dropbox.com/sh/ogg7nn5xkufllka/AAB3O1X3xM2Ed0pveWQVJ5asa?dl=0 Again, this should have been a clean upgrade of a finished project, but instead, the upgrade has just caused me a nightmare to fix over a dozen 1 minute videos that were 100% complete. Also, FYI, I do still have the original Project file and all the video source footage linked 100% correctly when the project rebuilt itself. Nothing is missing from the original project. Just for reference, here are all the finished video linked on their site that I now have to fix unless there is a way to upgrade this again without the issue: http://thomas-mack.com/virtual-tours/ Can I install the previous version to hopefully not have to fix all these videos and wait until Premier 13 is fixed and allows past Projects to be upgraded without issue??? I am so frustrated right now. PLEASE HELP ADOBE! FIX THIS!
