What Is Interlaced Video Scanning?
Interlaced video scanning is when a frame is separated into two half-frames.
Keep in mind that this is only the first half of the full frame of the video.

is displayed on a progressive monitor (like a 1080p one).
Why Are Most Blu-rays and Streaming Video Progressive?
This can occur when there is a delay between frames being displayed on a monitor.

As a result, there’s almost a strobe effect.
“But There Are Interlaced Blu-rays”
Yes, and they’re meant for interlaced monitors!

To each their own.
Why Are Some Broadcast TV Channels Still Interlaced?
Interlaced video uses way less bandwidth.
As such, it’s much cheaper to produce, transmit, and display.
On top of that, the time needed also decreases proportionally.
It’s for these people that broadcast TV still exists, and why interlaced video scanning is still useful.
Some dedicated viewers have even been able towatch some of these “terrestrial TV” channels for free.
Don’t let anyone tell you what to watch or how to watch it!
