After Effects Layer Rotation = Loss of Quality
Hi I am having a problem applying the “Demon face” liquify technique to my footage.
The technique itself isn’t the problem.
It is that as soon as any rotation is applied to the footage (1280x720p) a lot of softening blur is introduced, and too much detail is lost.
I have searched thoroughly for a workaround to my problem, and have settled on upscaling the footage to 2560×1440 before working on the reverse stabilisation/liquify process.
I am using AE CS6, have confirmed in independent test that it is definitely just the layer rotation causing this loss of quality.
Is the loss of quality introduced by layer rotation inevitable or is there a way to avoid it? Even at 2560×1440 I notice slight blurriness.

Generally, whenever you rotate an object you are going to lose a little clarity, it’s the nature of video & pixels. If you think you are losing more quality than normal, post a couple captures of the image straight and rotated and we can take a look and see if there is anything we can suggest.

Thanks for responding. Here is an example, the first being the original, the second being rotated 10 degrees in a precomp, then rotated -10degrees to straighten it back up which is what that liquify tracking technique needs.
The liquify filter wont be used for extreme warping just touch ups so it would be good to keep the fidelity of the original image if possible.
EDIT: [removed my example shots]

that’s just what happens when you rotate the image. If you download the project from video copilot, you will see that the exact same thing happens-detail is loss in the actor Sam. There really isn’t anything you can do to avoid that loss in this type of project.

Ah good to know thanks. Have settled on using the Sharpen effect to bring back some detail, seems to do the trick
