- Another issue is the appearance of visible lines or “combing” effects on the screen. This occurs when the alternating lines don’t blend perfectly, making it look like there are gaps or lines through moving objects. These artifacts can be distracting and reduce the overall clarity and quality of the video or image.

Sep 25, 2023 · When images are displayed on a television or other interlaced display, interlacing can cause visible lines or artifacts to appear. Interlacing is a method of displaying images where each frame is split into two fields, with each field containing half of the vertical resolution.
This means that interlaced video often has visible artifacts on computer systems. Computer systems may be used to edit interlaced video, but the disparity between computer video display systems and interlaced television signal formats means that the video content being edited cannot be viewed properly without separate video display hardware.
Jul 30, 2023 · Instructions by the Short Film Corner of Cannes Film Festival stipulate: “Please also make sure you upload a progressive (deinterlaced) video file, without any horizontal lines across the image—an interlacing artefact known as ‘combing’—particularly visible during sequences with rapid movement” (Festival de Cannes 2019, n.p.). As we ...
May 10, 2021 · These overt horizontal lines, appearing as pixelation around movement like out of an old school Atari game, are an artifact created from presenting an interlaced source in a progressive format.
The term “artifact” is used to broadly describe defects or foreign, unwanted elements in a video. There can be any number of causes ranging from lossy compression, improper conversions, to post-processing adjustments like sharpening and resampling. This guide will go over how to identify different types of artifacts, how they occur, and ...
Image artifacts (or artefacts) are unintended effects in a photo that were not part of the scene. Such anomalies occur due to various factors, such as camera limitations, lighting conditions, and the gear used. Some common artifacts are chromatic aberration, aliasing, moiré, banding, and other unwanted effects caused by Jpeg compression.
Aug 14, 2002 · Camera manufacturers know all about interlacing artifacts, and one thing they can do is to reduce the vertical resolution of the picture to reduce the amount of aliasing. This results in a permanent softening of the image, but it is probably more pleasing than intermittent motion-sensitive aliasing.
