How to keep aesthetics of your video

Keeping aesthetics of your video, is one of most important factors. To make your videos popular, and looking professional

&1 Basics

At first, you should color grade your video
This part isn't really hard, but really effective. The best option to color grade your videos is by using "Magic Bullet Looks" plugin.
Using it you either make your own preset, or use one which was made by the creators.
Color grading might seem to be hard, but usually is really easy, and after little bit of practice you can become atleast avarage with it.

Secondly you shouldnt use night in your scenery.
Even though, it might be weird, especially for editors who make illegal racing/chasing cinematics.
It is true, and is very important rule.
The issue with night scenery, is youtube bitrate system, which is making your video not really visible.
The youtube bitrate, is mostly focusing on light spots, and will make your video blocky on dark spaces.
So the issue with dark videos, is that until u render with high end options and 4k your video will feel low quality.
Instead of using night, try  hours like 4-6 AM or 18-22:30  PM for racing/chase scenes.

Third rule is to not use rain/thunder weathers in your videos

Fast pacing rain droplets, might ruin your video quality and make it blocky because of bitrate.
So until You use really high render quality, You shouldnt consider using these two weathers.
but, if you want to make your video scenery rainy, you can also use wather called "Clearing"
It has much less rain and it wont affect your video quality.

Fourth thing, you should pay attention to

Fourth thing, you should pay attention to is video immersion
depending on your editing style, you can use car sounds, music syncing the video etc.
easiest and most accurate way to add car sounds, is by making them yourself using Forza Horizon 5, or other racing game.

To sync the video with music theres few options, and I will point them out by professionalism and final effect
First, and easiest way is to sync the video with music basses. It is very easy but isnt really effective, you should only practice it at the beginning of your video editing carrier.
Second, and little bit harder is syncing the video with a melody instead.
It might be kinda hard with some sort of songs, but even though it's much more effective, and actually pays off.
Third, and the hardest way is building whole story, and syncing the video with additional sfx like gear up's etc.
Could be literally anything. Even though its not that hard, it is really time consuming, and will take you a while.
I think its the best way to firstly write your video story and then adjust and create clips.
