screen tear effect
Posted: 25 Jul 2011 11:50 PM
Looking for an effect that causes screen tear, similar to the subtle tear seen at 0:29 in this video: http://www.youtube.com/watch?v=b52bwPam7O8&feature=related

I've looked everywhere, but can't find anything. The split screen thread on this forum wasn't what I was looking for. Can someone hook a brother up?

That is very subtle. From what I see, it's like the video is offset upward (maybe 5% or so of the total screen), but leaving the original part of it showing at the bottom.

Are you sure that was an added effect and not just a glitch in the camera?

I would think you could do something like this in WMM 6.0 with a custom pixel shader, but I guess I'm not sure how many people would find it a useful effect. Are you on WMM 6.0?

The tear was intended to look like a camera glitch, so I'm not sure if it really was or not. I'm only looking for an effect that mimics a tear like that, maybe even offset 10% rather then your guess of 5%.

I'm not certain what version of WWM I'm using. I'm using an XP, however, so I know it isn't the most recent version. Will I need to update WWM to enable an effect like this, and can I? If it's avoidable, I'd rather not update it, but I will if I need to.

I don't have a good solution under XP (which uses version 2.1 of WMM), but let me look at some options...

Okay, one choice would be to use a "Move Up" effect. It wouldn't have a duplicate of the original video below, but if you use it on a short part of the video, it would jump upward for a second simulating most of the glitch effect you want.

To get the effect, go to TheFXArchive.com. Under XP Effects, look in the Movement section. Find 'Mallett65 Move Up'.

Sorry for the late reply. I checked out the demo for the effect, but it isn't really what I'm looking for. Do you know of any other possibilities? Perhaps a transition, similar to the screen split transition, only the top half is lowered and offset or something...? Just speaking my mind, thanks for helping me out.

You can get it by duping the clip, applying 'Mallett65 Move Up' on the second and use 'SPLIT: Horizontal 2:1' (view post 164756) with an adjusted Progress value. It looks like there needs to be a little bit of contrast applied to the lower clip too.

This works well, the only problem is that the move up effect lingers after the transition is over, as the transition won't last through the whole second clip. Is there a way to fix this? Otherwise, this is almost perfect, thank you.

Do the move/transition in a new project then render it and import that into your main project. Then you can trim off the extra start and end bits.
