Blurry faces after Warp Stabilizer VFX?

Hi guys, may I know if it's safe to use Warp Stabilizer VFX for an interview with a few people sitting, or what is the best setting for this scenario please?

I just tried but at some point their faces became blurry and the scene looked like out of focus. My setting was:

Result: Smooth Motion

Method: Subspace Warp

Framing: Stabilize, Crop, Auto-scale

Thanks all for your comments and I believe I've to agree with pablogrollan that there's kinda a 'shake' causing blurry faces... I let it go and output the video anyway.

Hi Quincy,

That sounds like it's natural motion blur. If the original footage was shaky, at certain moments the movement of the camera makes every element apper blurry (due to motion blur). While stabilizers are getting smarter, pretty much all they do is re-position and re-scale the frame to counteract the camera movement. Some, as the Warp Stabilzer go as far as actually bending (warping) the footage, but as far as I know, no stabilizer gets rid of motion blur -though should be technically possible-. That's part of the footage itself.

Go check the original footage on that same frame and you'll see it's just as blurry.

Thanks for your reply but I did check the original footage and it's not blurry at all. I suspected the reason is that a person was passing by the interviewees before that happened, and it confused the Warp Stabilizer VFX making the faces a bit shaky/blurry? Should I not apply this effect for this part or is there any other ways to solve please?

You could try applying it with a method other than "subspace warp" to see if the blur is caused by the warping. Also uncheck "perspective" and see what it does by just re-positioning and re-scaling the frame. If you post both screenshots (frame without stabilizer and with stabilizer) I'd be able to help better!

Good luck!
