What does "interlaced output" actually do

[syrz05]

Sorry if this is a stupid question but I enabled interlaced output and the video is still not interlaced, so I'm wondering if its supposed to somehow interlace videos and there's just more I have to do to get it working, or if it does something else entirely.

Hey! I have to oblige, I checked on the "interlaced output" thing and the video DID get interlaced; there are lines in the head switching thing and when deinterlacing is enabled, there is a difference.

[smfthe1199]

The thing is that you'll notice the lines down here in the head switching thing, and not the contents of the video itself.

So it doesn't do this?

[smfthe1199]

Yep!

No. The video must be interlaced first to get the weaving artifacts. Progressive video (non interlaced) will just be downconverted, and deinterlaced. VLC Media Player has a "Phosphor" deinterlacer, and if it is set correctly, will give you the weaving artifacts you want!

I was referring to this.

The "Interlaced output" checkbox determines whether the video metadata says the video is interlaced. Many media players will automatically de-interlace such media upon playback. If you're using VLC, you can try disabling it via the Video > Deinterlace menu.

I tried upon opening a video it doesn't interlace and it doesn't interlace the entire video, the weaving artifacts gets interlaced.

the input video has to be interlaced itself

Here's a better explained video I made of what's going on:

I made a grammar mistake, I am supposed to write "look at it" not "look in it" -_- , forgot to correct that.
