Image info missing on borders when compared to offline
on May 30, 2012 at 10:55:02 pm

Rendered a Red job overnight - It seems to be missing image info on the left and right edge of frame when compared to the offline. Doesn't appear to be a scaling problem as the footage lines up perfectly.

Any ideas?

If you go to Format>Input>Source Blanking OFF, does that solve it?

It does solve the black edging - but now I am left with strange patterns of light lines near the edge of frame - that aren't present in the offline (which I believe was done using redcine -> pro res)

After some experimentation I have found the artefacts disappear if the "Image Scaling" preference is set to "Bilinear" - The two higher quality settings "sharper" and "smoother" both exhibit different edge artefacting.

FYI I am working with 5120 x 2060 RED footage, in a 2560 x 1080 timeline, with Output Format set to 1920 x 1080 (so outputting 1080 with black bars).

Interested if anyone else has experienced similar problems - would love to know if its a bug, a known issue, or a problem specific to my workflow?
