  • Superhite edge on composite

    We’ve been running into this problem for a while now. When an image with a white background is cropped or repositioned and rendered, we get a superwhite edge. This happens in both 8- & 10-bit. The specific timeline I’m staring at now is ProRes, but we’ve seen this happen in Uncompressed as well.

    Try this:
    1.) Create a white color solid in the timeline.
    2.) Duplicate it to the next video track so they are ontop of one-another.
    3.) Reposition the top solid.
    4.) Render & look at your scopes.

    Despite both solids clearly being 100IRE, there is a superwhite (110IRE) edge.

    We know some workarounds (nesting sequence, applying custom Broadcast Safe, etc), but we’re looking to treat the disease, not the symptom.

    Has anyone else run into this and fixed it?

    Adding image of scope to illustrate issue. That little white dot in the upper left is our superwhite line. No idea what is causing it. Seems like a composite issue on render.
