That was my fault. What were the specific shutter, aperture and gain values for this clip? July 12th, , PM Chris Andrews. Right , after finding out exactly what settings everything was on I may have found the problem , the gain was on auto and was very high at Do you think these setting could be causing that grainy quality.
Thanks Chris. July 12th, , PM Roger Averdahl. Originally Posted by Chris Andrews. Looks like the problem was the auto gain , thanks for helping me find the problem guys! July 12th, , PM Doug Jensen. NEVER use auto-gain under any circumstances.
If you must increase the gain because you are in a low-light situation, always do it manually so you are in control of the setting and can choose when it is changed. That's right where it should be under normal shooting conditions. You also might want to try shooting 25P since interlaced is a little old-fashioned now. July 12th, , PM Sam Young.

June 24, Dealing with grainy footage can be extremely frustrating, but here are some ways to reduce or avoid it before and after you hit record on your camera. Why does my drone footage look grainy? There is now one reason that could be caused your drone footage to look grainy — is normally a combination of factors.
For example, your ISO is set to too high which introduces a significant amount of noise. You may have the sharpness setting set at the wrong value which is forcing the drone to do a load of processing.
These are not the only reasons why your drone footage looks grainy. There are plenty of other reasons which we can discuss in more detail, below. One of the most common reasons drone footage looks grainy is because the drone is increasing the ISO setting to compensate for filming in low light. The ISO range of a camera tells you how sensitive the sensor is to light.
Low numbers require that a lot of light enters the camera which results in a much better image. Typically, when you are flying a drone light is not too much of an issue because you are generally flying in daylight. However, if you are flying in cloudy conditions or you have a new density filter on the front of your drone and it is not a bright setting the ISO needs to be increased.
ISO ranges typically start at and go up to 12, As a general rule of thumb is always best to use the lowest value and aim to increase the amount of light entering the camera. As the number increases the sensor works harder and harder to compensate for low light this introduces a fair amount of noise. To reduce your ISO range you can remove any neutral density filter that is over the lens and you can record in brighter settings. As your drone is flying you have the option to save the first person view of your drone on your smart device.
To make sure that you are correctly analysing your drone footage you should make sure that you are getting the footage straight from the SD card or internal memory of the drone. Do not rely on any footage that you have saved on to your laptop unless it is come straight from the SD card at the highest possible quality.
You can check this by right clicking and selecting the properties of the video. If you are not sure whether or not your SD card is suitable for high-definition video recording you can use the internal memory that most drones come with.
Most drones have an internal memory of approximately 8 GB so that you can test whether or not the SD card is causing noise by having a slow write speed.
Sometimes, when we are comparing our drone footage we are not comparing drones and cameras of the same quality. You see, the sensor that the drone camera has heavily dictates the quality of the image that you can expect to get from the drone. A camera sensor is a rectangular grid containing millions of tiny pixels. These pixels collect the light that lands on them and sends that information to the processor.
The camera sensor size is the most important factor in determining the overall camera performance and image quality. To measure brightness of the image the sensor detects how many photons of light hit the sensor and convert that into electrons. The colour information cannot be determined simply by counting the number of electrons are generated at each pixel.
So a colour filter is placed over each of the pixels which filters out different energies of photons to create a colour profiled image. The physical size of the camera sensor also determines the size of each pixel.
The physical senses in the camera are provided in terms of width and height which is usually stated in millimetres. The larger the sensor the more surface area there is to capture information about the light over the exposure time.
A bigger sensor however does not necessarily create a better or more high quality image.
