Vegas Movie Studio Platinum 14

Hi there. I am absolutely desperate for help. I've searched solutions online, and while some have worked for others, none have worked for me. I just want to know a concrete way to resolve this issue.

I've been using Vegas for years, but I just bought a new computer. HP Envy laptop, Intel(R) Core(TM) i7-8550U 1.80GHz 1.99GHz, 12.0 GB of RAM, 64-bit operating system, x64 based processor.

Not sure how much of that you need, but let me know what else you need to know.

I've been using OBS, a program that allows me to record whats happening on my computer screen, for a while as well. Now that I have a new computer, I've newly downloaded both OBS and Vegas. Now when I import mp4 files recorded from OBS into Vegas, they appear glitchy, dark and discolored, blocky, and completely unusable. They still look this way (though to a lesser degree) after rendering.

I am at a loss. I don't know the source of the issue, but I know it's possible to use these files in Vegas because I've been doing it for a few years now. I'm not sure what my new computer is lacking, or the new version of OBS perhaps.

Please, please help. Thank you.
