How to Fix Flicker and Video Noise in Drone Videos
Hey guys welcome to Neat Video tutorials Here at Neat Video, its our mission to help you avoid digital noise and improve video quality. This tutorial is an addition to our blog post on the topic of how to improve the quality of your aerial videos. If you havent make sure you check it out for a ton of information that will put you on course to creating killer drone shots In this video were talking about a few of the most frequent issues our customers run into when working with drones. Ready Lets take it away and get those drone videos looking smooth and sexy. First up lets talk about Intensive sensor noise.
This type of noise is often found in drone videos due to the small cameras limitations. Most consumer-grade drones have tiny camera sensors and they dont handle low light. Well. The second most common problem is frame flicker. The problem here is that the video codecs used by drones, work by dividing clips into groups of frames, Usually 8 frames are compressed at a time.
Often, this results in a little jump in brightness happening over and over Thats. What we call frame, flicker, Next issue is compression artifacts. The codec is the culprit here again. See when the codec divides the video into groups, it only records the first frame as a whole. The next 7 frames are inter-frames made up of the difference between the current frame and the ones before When the codec hits the storage limit.
It skips some of the details and turns some areas into blocky spots. The further away from the first frame, you go, the more of these blocky spots. Youll, see Hello, compression artifacts, And the last thing we going to talk about today is blurry spots in shadows. This one is caused by in-camera noise reduction In drones when you set sharpening to 0 or below the camera. Activates internal noise reduction.
As shadows naturally have more noise, the internal noise reduction jumps in and in the process ruins all the details there And were not going to let that happen on our watch. Ok, so now you know the issues. What can we do about this? The first thing is to set your cameras sharpening to 1 or above This will deactivate the drones, in-camera noise reduction and preserve the details. If theres noise, you can do a much better job of dealing with that in the edit than your drone can do.
In-Camera. Speaking of the edit, when you apply Neat Video to one of these drone clips, you should first try to find a part of the clip. The most noise, Then you need to locate a key frame. Ok now open Neat Video and build a noise profile using that key frame As usual. Look for the area of the frame without details.
If you cant find one use, one of the Generic Profiles Verify and, if necessary, adjust the noise profile using Noise Level Tuning Assist until all the noise and compression artifacts are gone, Also, increase Temporal Filter, Radius to 5 and disable Spatial Filter, Click Apply And heres. The result spectacularly smooth drone, awesomeness.
