Aug 18, 2023 · Key Takeaways. Interlaced scanning is still used in some broadcasts because it saves bandwidth and allows for more visual information to be displayed without increasing transmission size. Interlaced video scanning can result in visual errors, like interline twitter, but progressive scanning is more stable and less likely to have issues.

Interlaced video is a technique that was originally created and made popular before the advent of digital televised content. First developed over 70 years ago, it was primarily for television video formats like NTSC and PAL. At its root, interlacing was an early form of video compression that was used to make the video look smoother while sending l...
Unlike interlaced content, progressive video is a video track that consists of complete frames. There is a slight asterix to this statement as techniques like interframe can be used to compress video content to remove redundancies from frame to frame (read more about the interframe process). Even including this technique, progressive video content ...
To be blunt, the answer is it actually doesn’t matter which is better. Many playback methods, like computer monitors or modern HD TVs, do not support interlacing. So even if interlacing provided better looking content, a broadcaster would still want to go with progressive delivery due to support for this method. Otherwise, the broadcaster would be ...
Sometimes a broadcaster needs to use an interlaced source for streaming. In other words, taking an interlaced source and make it progressive or watching it in a progressive medium, like a computer monitor. This need can range from wanting to use an older broadcast to using an analogue camera that supports interlacing. Converting the video involves ...
A lot of this article has talked about interlacing as a legacy component, but that doesn’t give a fair representation. A lot of analogue cameras, for example, are setup to deliver video in an interlaced manner. Even some modern digital cameras still offer interlaced mode. Reasoning behind this is partially for compatibility and also 1080, even 1080...
Thankfully, there is a process called deinterlacing which can solve issues created from presenting interlaced content in a progressive medium. Deinterlacing uses every other line from one field and interpolates new in-between lines without tearing, applying an algorithm to minimize the resulting artifacts.
Deinterlacing is done at the encoder level for live content. How this is done varies from encoder to encoder, with some enabling it through a simple check box. On Wirecast, this is found under Sources and then “Show Source Settings…”. From this screen you can select your source, with most having two options available. For example, a capture card so...
Sometimes referred to as a 2:3 pulldown, three-two pull down is a process used to convert material from film to an interlaced NTSC display rate. This involves taking content created at 24 frames per second and converting it to 29.97 frames per second, which is the signal frame rate of NTSC video. This process involves duplicating fields, two from o...
Also known as inverse telecine (IVTC), reverse telecine is a process that can be used to remove the effects of taking a source and stretching it from 24 frames per second to 29.97 frames per second. This involves removing the added information from the frames to return it to the 24 frames per second. For example, frame 1 might be converted into fra...
Yes, if the source is not interlaced than the result can introduce needless artifacting if the deinterlacing methods are inadequate. This will be most noticeable on motion, which will have a greater loss of quality. Fine, rounded details can also suffer, often converting a smooth look into a blocky look, like mini stairs as would be common in video...
