there are a few threads in the archives on this….but this is what I do…
Record black onto a VHS. Then capture it into your machine while rewinding the VCR. So you get the horizontal lines with some noise and crap over black. Layer this up and play with some transfer modes.
Also, play around with different ways of rewinding the footage, rather than just a straight time remap. Maybe posterise time or echo?
Maybe distort the footage a bit while it is rewinding….A simple one could be the wave warp at 90 degrees stretching in and out real fast.
ummmmmm…..maybe wiggler the position a little. Maybe wiggler some blur….OR, with the wave warp make a black/white matte and use it as a displacement map and compund blur at the same time.
Adjust curves/levels?
……..hope this helps……….
