Any way of enabling interlaced video mode?

[el_rika]

Interlaced blend modes can result in a very smooth "motion-blur" like effect, that can enhance the movement and overall smoothness (if you fancy that effect of course).
For ex. in Retroarch this can be achieved via shader, and in AetherSX there's a direct emulator option which works beautifully.
Can we activate this somehow in Dolphin?

I believe Dolphin emulates all games on interlaced mode by default unless you check "Enable Progressive Scan" in the Graphics options (I mean, if that's still a thing; haven't used/updated Dolphin in a while).

That's not wrong but it's not correct either. The GameCube and Wii are progressive-rendering consoles, then output in interlaced or progressive. Dolphin runs in "interlaced mode" (unless you tell it otherwise) but Dolphin doesn't emulate the interlacing components of VI, so Dolphin always outputs a progressive image. To get an actual interlaced image out of Dolphin, you need to pair it with hardware that will interlace the image for you. After all that's what VI does for interlaced output - interlace a progressive signal.

Yes there are exceptions but the above is correct for 99.999% of the library so don't give me any guff.

That sounds terrible, and there are much MUCH better ways to achieve motion blur. However, there's no reason you couldn't create a similar shader for Dolphin. Or just use reshade and use whatever retroarch is using on anything, including Dolphin.

That's interesting, Is there a tutorial on reshade for android 11? Never used it myself.

I would do a shader if i had the knowledge. I tried to use the Retroarch ones, but they are not compatible unfortunately.
Looks very neat though, even for 2D games...maybe in the future someone would develop a tool for converting the shaders into a compatible format.

There would be no point in this, since (as explained above) Dolphin outputs progressive scan at any settings.

Smoothness is achived traditionally in emulators by increasing VPS/FPS (internal fps of a game). You could add on top on this any blur shader.

It's not about higher framerate, most games are already 60 fps. It's as i said, about the perceived smoothness of the motion blur-like effects, which, admitedly is not everyone's cup of tea.

So the only way is via shaders, which atm don't have a Dolphin compatible version.
