Sorry for double post.
Actually, VLC deinterlacing was set to blend, I changed it to the discard deinterlace option and the issue between the NTSC and the PAL one wasn’t really there anymore. Blend seemed to throw the PAL source a bit for some reason. Encode is better for PAL, but slightly softer.
Here’s a couple of comparison pics.
