Adobe needs to fix Premiere 2020
I really don't want to hear, clear this cache, turn this one, make proxies etc. I just sarted a job in 2020's newest update and I could barely scrub the timeline whether using frame sequences or MP4 to edit with. I had to revert the project to work in 2019 and now everything is fine. I don't know why I thought anything would be different, since I had the same 2020 problem last time I tried it. There is something seriously broken in 2020 and it just needs to get fixed before they keep releasing new updated versions with talk about performance improvements. It doesn't work and there's lots of others besides me complaining about it online.
