Artefacts described in this ticket are improved in SVP with Rife v4.15 but still present

[netExtra]

When using SVP, Rife tends to have less artefacts than the other mode. I notice that Rife 4.7 has even less artefacts than 4.6. But the problem is that the artefacts that remain tend to be worse. The biggest one I've seen recently is a character appearing and disappering every other frame. Is there any use for me to point out the location of these artefacts ? Is there anyone I should send them to?
