Why my MOV Videos don't work properly ?
Hello everyone,
I Have an Issue specifically with .MOV FIles, indeed when I drag them onto the timeline it's fine, but after a few minutes of work it starts to go... Back and forth, jumping from one frame to another, it is not a render Issue either because when I export it, the lag persist with the exported file.

I Have tried several things to fix this but If one problem goes away another comes next.
For instance;
I've tried to convert MOV files into MP4, and other extensions like MPEG-TS MKV, but another issue comes next, when I do that, the video is flipped upside down, It wouldn't be a problem if it was just one video, but i have hundreds of videos that I need to constantly check, and it's hard to work with upside down clips in the preview window, obviously I could flip by rotating but I need to have the clip the right way in the preview window. I've also tried to convert it and flip the video in a converter, but there's still the issue of horrible quality loss.
I have also tried using proxies, It works to a certain extent, the videos don't jump back and forth, but on the final export it still has issues, that for some reason the clips don't start at the frame it needs to start. Other than that I need to work with some videos that are vertical (1080x1920) and i didn't find a way to make vertical proxies so when I try to fix this issue with vertical clips, I end up with a noodle shaped video.
I've spent hours trying to figure out what's wrong, and reading different forums to no avail. I really need your help.
Also don't get me wrong, I've tried simple ways to try to fix it like deleting cache media, lowering the resolution, but as i said earlier, I don't think it's a render Issue, If you want my nineteen cents, I think there's some wierd shenanigans with end of support for quick time 7 era formats and codecs.
Thank you for reading and for your help, god bless.
