I have an image that has been distorted with the standard Liquify effect. To speed up the design of the effect I used a reduced resolution version of the image I want to work with, thinking I'd be able to uprez it later by replacing the source footage. This is possible in most cases in AE.
However, I've discovered that Liquify seems to be resolution dependent, and none of my usual tricks are working. Either I'm stuck with the low rez version of the image (actually a single image that's being output as a sequence with an animated effect) or the effect is not scaling with the new resolution.
In particular, precomping the footage then replacing the higher rez source scaled down into that, then resizing back up downstream does not seem to work. If I turn on continuously rasterize in my source comps I get the higher resolution but the effect then only covers an area the size of the original comp it was applied in. If I turn continuously rasterize off, of course I can uprez but it's pointless as I'm not getting the full rez of the source image.
The only solution seems to be to create the effect anew on the full rez image.
Anyone got any ideas? This is annoying as hell as normally this type of thing isn't a problem in AE.
