After Effects Tutorial - De-rezzing your video, part 1

Here's the first of a new tutorial series showing you how you can add all of those funky distortion, interference, blockiness and noise effects to your footage. Broken transmissions, static bursts, digital compression artefacts, ghosting and colour separation will be covered in later tutes, but this one shows you how to 're-interlace' your progressive-scan video to make it look more like old-school MiniDV.

if ur looking for taking bad photos like that why dont u just buy a cheap rubish camera instead of a realy exspensive one and having to do all this messing about

@0103mikecartoons Sometimes VFX and motion graphics calls for a particular look-and-feel. If you're looking to recreate a 50s-style 8mm camera, you'd drop the resolution, crop the frame, add vignetting (and probably some lens flare and film burn), play with the colour balance and generally screw around with your perfectly shot HD footage. This is just another technique to use when it's needed.

but why would anyone want to learn how to ruin his footage, by interlacing it?

[shortformvideos]

@eladbari Same reasons as I've given the other commenters here. It's about context. If you need to recreate a scene that calls for an old-school MiniDV look and feel, then this technique could be handy. Just as we like to add vignetting, film burn, flare, desaturation and all kinds of garbage to material to re-create a certain look or perdio, this technique can be used in the right circumstances - I'm certainly not suggesting that it's a good look for footage in general.

So know how do I get my 1080i video to look like its a progressive video?

[shortformvideos]

@manjamfan If it was me, I'd drop it onto the timeline in Premiere Pro, right-click on the asset and select Field Options, and pick the Always De-Interlace option. Then export it as a progressive scan file. In AE, it's a little more complicated, but if you search for 'After Effects Deinterlace' you'll find a bunch of techniques to choose from (some are a little like the above technique but in reverse). While others use Motion Detect to selectively deinterlace. Hope that helps!
