I made a 4K project. How can I translate it into 2k and full HD? I heard that a 4k project should be placed in a full HD composition and reduced by 50%, but why? After all, you can set the desired resolution in the render settings. This is done only for convenience buyers or something I do not know?
I never do this. From my experience I can say that sometimes this can significantly degrade the quality of some graphic elements in the frame, which will not happen if you put your 4k project in a FullHD precomposition
Thanks for the advice!
You can just try to render your project in two ways and then compare these 2 videos to understand whether the quality deteriorates in your case
