Best Software/Node for Face Restoration in LTX/WAN Videos

When making I2V videos with AI, we all know that image quality can drop pretty quickly, but nowhere is this obvious than when it comes to faces. I've been making videos with LTX 2.3 (formerly Wan 2.2) and this is consistently an issue. What are the best ways to do face restorations on videos? aDetailers are obviously a good choice for images, but it this approach is very slow for videos, and you can only do an incredibly light denoise before the facial animation starts flickering terribly.
