Help me please to identify a type of artifact appearing in PAL DVD footage

[artemiy1701]

Hi! I'm a newbie here, hope I get help
What kind of artifact is it and is it possible to fix this? I circled it in red, but in general it appears throughout the frame, I don't even know how to describe it correctly

You need to supply a sample of the original MPEG 2 video. But it looks like poor scaling or poor deinterlacing. Maybe an NTSC to PAL conversion?

For the flickering applying QTGMC(InputType=1) after normal QTGMC() should help.

Yes, QTGMC() smooths out the aliased edges, reduces the buzzing, and keeps the smooth motion.
