DVD Studio Pro: Avoiding Artifacts

Artifacts are aggressive pieces of data compression that gets applied to images, audio and videos. It gets rid of your data that may be too difficult to store in the available data rate. This is not good to the viewer and often causes error. Even small levels of noise or color interference can have a huge noticeable impact on the quality of your final job. Some of the video artifacts may come from overshoots and undershoots on synching, codec and pixel clock jitter, flickering from poor isolation of audio and video and not having termination resistors. There are a few steps that can be taken to avoid artifacts or minimize their effects. Some of these steps are listed below.

Tools and Materials Needed

  • Noise filters

Step 1: Shooting the Video (Especially One in HD)

Try not to zoom or pan while shooting the video. Also, try not to do a long telephoto shot where heat waves are able to ripple through your frame. If you are filming near uniform color areas, like skies or shadows, noise and color distortion will occur. The more the camera's sensitivity is increased, the more light you will need so that too much noise will not be produced. When shooting, try to shoot in the lowest ISO that you can shoot in. With the right exposure in the camera, you should have minimal noise problems. When you start shooting your job, over-expose a little bit. When a sensor catches the darker areas, there tends to be more noise. 

Step 2: Noise Artifacts

To avoid unwanted noise, you can apply noise filters or spot edit your job. There are noise reduction programs available which will correct noise artifacts without messing up the quality of the job. Beware of using these because although they help you clear up noise artifacts, they have low quality results. Your job may appear blurry or have a watercolor looking effect. Another way to avoid noise artifacts will be reducing the amount of contrast correction you do. You will want to have your lighting right in the beginning. The more you add contrast to fix an image, the more you add noise contrast. 

Step 3: Editing Your Job

There are a few post editing programs that will create noise artifact once you save the changes. You can try to edit your job in a non-compressed format before you save it in the highest video quality.


The higher speed DSP video systems have a few sources of noise that can disrupt how your system operates. If you have a little bit of insight on the sources of the noise and radiation, this can help you to minimize any audio and video artifacts. Just doing a few things up front can save you time and editing later. Two techniques that can help limit artifacts are PCB layout and return path decoupling. They also help to handle system artifacts effectively.
