I bought and downloaded a bunch of transitions and luts and animated packs from Humble Bundle. I downloaded the ones made for Vegas. I have Vegas pro 16 currently.
I unzipped and that as far as it will let me go. I don't know/understand how to add the transitions into Vegas. I've tried the presets manager. I've tried to add them directly into the program. I tried to drag and drop.
They are .Mov files
I can't seemed to get it to work
I've search every where.
Thank you in advance for the help.
Re LUT files ... LUTs commonly have an extension of .cube. They just need to be placed in a folder of your choice and name on any of your HDDs or SSDs. To use them in Vegas Pro 16, add the Vegas VFX 'LUT Filter' to the video media on Vegas Pro's timeline and then use the Browse button in the LUT Filter's VFX window to drill down to the folder where you stored the LUTs, and select (click on) the LUT that you want.
.MOV files are media (video/audio) files, they are not executable programs (e.g. an .exe file) that install a program on the computer. Being media, .MOV files are placed on Vegas Pro's timeline.

@HelloSparkles MOV files are just containers that can contain many different types of video. We need to know what's actually inside the MOV files. However, without knowing that my guess is that you need QuickTime installed and have it enable on the preferences - Deprecated tab.
