November 20, 2006 at 1:00 amIt would be much faster to record a dirty white image to a VHS, fast forward it, and shoot it or capture it, than trying to recreate it in AE…

November 20, 2006 at 12:46 pmunfortunately it needs to be generated with an alpha mask etc to go into another comp, so will need to be manually made.
Anyone else have some tips???

November 20, 2006 at 2:03 pmCan’t you just capture in a fast forwarding VHS on a white fame like suggested and then in AE key out the white for your alpha key of the lines? Then you could quite easily dirty up whatever picture you want to then put the lines over in AE?
OR just play the footage you want to use onto VHS directly and then grab back in? That make any sense?!?

November 20, 2006 at 2:36 pmShoot a still of a white card. Use a sponge and India Ink to create the lines across the white card. Do this a handfull of times. Cycle these frames. Crush the levels in a bit and invert the image so it’s white lines across black. Then use this footage as a track matte on other video, or use transfer modes like “overlay” over other video.

November 20, 2006 at 3:13 pmI threw something together that was coming along well but I got kicked out of the edit bay.
I duplicated the lines pretty decently by generating a grid with a width thats larger than your comp and a height that leaves 4 or 5 lines across the screen. Set the border for the thickness. Rotate it slightly and then add a turbulant displace. Set the size to about 10 and an amount of about 80 and wiggle the revolution. wiggle(30,180) And I made the lines scroll down the screen.
Then in a second comp I used a grid to make scan lines. The width again is larger than your comp the height and border set to about 2.
In the final comp place your both comps. Use the scan lines as a matte.
This at the moment won’t look exactly like what you want but it’s well on it’s way.

November 20, 2006 at 5:59 pmDraw some grey-scale gradient lines, wiggle their location, apply noise or grain, apply levels to up the contrast. Possibly apply a scatter filter in a lower-resolution composition, then scale it up and blur.
Then play with some edge filters and channel offset to make it seem a little more analog.
