Smps - cooler master v1000 is good ?I would suggest the 8700k instead or the 9900k if you can get it.
More threads matter in video editing. The above build looks good.
But I would change the Samsung 970 for a drive with higher endurance like the corsair mp510 for your video editing tasks.
And also maybe to a case with more airflow. Like the lian li Lan cool one...
