This was caused by motion enhance low setting, creating a ghosting artifact from the panel overdrive.
Hey all. I have what I believe to be a new NX series image artifact that I would like to report and perhaps have others check out to confirm / diagnose / etc.
I noticed that on a particular scene in X-Men Apocalypse that there is a very noticeable yellow "ghosting" artifact in the image on the JVC NX when it is in either HDR color profile or BT2020 color profile (NX7).
I have confirmed that this image artifact happens both on my NX5 in HDR color profile and in a friends NX7 in BT2020 color profile. Switching the projector to rec709 color profile makes this image artifact go away. Iris is completely open and set to manual.
Here are video clips demonstrating this artifact.
HDR / BT2020 artifact:
In case you can’t tell, the artifact is the yellow spots all over his face, chin, and neck as his head moves up the screen.
rec709 no artifact:
I have recorded the scene on my camera in slo-mo to more easily demonstrate the artifact, but I can assure you its easily visible in full-speed playback too. This artifact happens all over in numerous scenes in this whole section of the film where quicksilver is rescuing people from the explosion.
Here is the source scene clip for you to try yourself:
It appears that this artifact happens in between frames, so you cannot see it on any single paused frame. If you step through the video frame-by-frame however, you can see the artifact, but only as the frame transitions to the next frame. Once the frame has been advanced and is at rest, there is no artifact any longer.
This may be something we need to send to JVC to look into.
