So, just as a bit of background. I do tiktok snippets of my gameplay, its not been anything big, i just like to do it as a bit of fun. It keeps me occupied and i like to use my imagination in doing a little snippet of something which hasnt been over edited like what some of the other tiktokers do.

ANYWAY, everything was working perfectly fine, i put my SD card in from my switch, (no viruses, its never left my switch from the moment i bought it) transferred a load of videos from my switch to my laptop, tried to edit them, and nope, they just kept coming out like this. Okay then, what about if i go back to editing captures from my laptop, and nope. Preview still looks like that. Okay then, what happens if i just edit it as much as i can from what i can see and hear, and then render it? The render looks just like the preview. Now, all of that was on Vegas 16, so, thinking, oh, maybe ive broken it. So, someone informed me that humblebundle was offering vegas 18 for $/£20, great, maybe that will fix my issue.................nope.

You name it, ive tried it, from what i know as to how to fix an issue within vegas. Re-install, done, repair installation, done. Restarted my computer, done. upped the amount of ram, done. Using footage ive downloaded from the internet, still pushes out the same concoction of what looks like a pirated film from the days of Kazaa and Limewire. Ive even changed which graphics card it uses, to no avail. Google after google just tells me to lower the quality of the preview, and nope. Doesnt do a thing.

Now, i get that some of you might be thinking, hmm, maybe the files ARE corrupted. I thought the same, so i downloaded hitfilm. Works fine there. No issues. I could understand if it was a compatibility issue within Vegas itself, but ive been editing the same file type for so long now, i would fail to see how that could be an issue, and even then, that doesn't explain when ive downloaded a video in a different format altogether, it still produces this mess.

Specs:

Ryzen 7 - 4800h with integrated graphics which have been turned off since day one

16gb Ram

RTX 2060

Storage: Doesnt seem to matter if it comes from an external SSD, Internal NVME or my 6tb Backup Hard Drive, same thing, every time

Im fully aware its not the most powerful laptop in the world, but at the same time, its not exactly a lightweight either.

any help, would be greatly appreciated
