Fractal Noise VHS Tracking

[Eric Schuran]

Thanks for the reply 🙂

The guy in the last vid mentioned he used fractal noise, along with a bunch of other people who did the similar effect. I guess I could try distortion but I just don’t want to head off in a totally different direction when I’m so close.

Create a White Solid that’s 40 x 120 pixels. Apply Fractal Noise. Leave everything at the default setting for now. Scale up the Solid until the width reaches the edges.

Within Fractal Noise, there is a Transform property, deselect the Uniform Scale checkbox. increase width dramatically. Increase Contrast and reduce Brightness until you see horizontal lines. Set Blending Mode to Screen.

Adjust Transform>Scale and/or Fractal Noise Scale Width.

I tried that method, and when I selected the blending mode and then screen, the whole thing went white:

Well, I managed to figure it out … although changing the blending mode to screen seems to make my solid layer pure white … not sure why that is, so I just kept it on “normal.” Here’s what I got from messing around:

Your comp looked white after apply a blending mode cos’ you didn’t have another layer below.

What you now have looks decent but it can be improved. Try increasing the Width Scale within FN’s Transform property. Add Fast Blue to soften the edges of the lines.

Roland:

I tried that … same result. I just had a white bar when I did what you said.

[Roland R. kahlenberg]

Lower your contrast to about 160-200 – it’s way too high and that’s why you’re getting the full-on white.

And FNoise>Transform>Scale Width should be twice as long or until your lines stretch across the width of the entire comp.

Look at using Levels to increase the luminance of the Fnoise layer rather than the Contrast found in FNoise.

No matter what I try … I get that result. There’s must be some kind of breakdown in communication here, because I followed the instructions explicitly.

As you can see from the photo, the width is as big as it gets … it can’t get much larger than that when it’s maxed right out. Furthermore, the bar turns white only after I change the blending mode to “screen.” If I leave the settings to either “None” or “Normal” it looks just fine. Not sure what the “screen” blending mode is supposed to do, but clearly it doesn’t work from what I posted above. Unless you have an actual screenshot or example, I can’t really do anything with those instructions because I end up in the same place everytime, no matter how many times I mess around with the luminance, etc.

In my opinion, I think the video of what I got seemed to be pretty close. I just wanted to see what everyone thought of it. I don’t think it was a case of striking out … I think it was a success unless it doesn’t look convincing to anyone here. I will add the fast blur to it later and see how it looks, although this looks really nice thus far.

What I was mainly talking about was the blending mode to screen … it seemed to turn the otherwise good-looking static into a block of white. I just didn’t see the point in doing the “screen” part when it looked fine in the first place.

hey ive been trying to find this out too for a while, and seeing this has helped me alot. i actually started having the same exact problem too! i think i got around it tho by instead of using screen, i duplicated it and used a luma matte. that way the white parts are nice and solid. i am having trouble in that my noise is making the lines super thick and not going up and down, they are just dissapearing and reapearing
