I just discovered a CURE for the lower bottom artifacting that is present when the CASSIE downconverts in HDV and produces SD clips. There is apparently an underscan situation in SD resulting in a line or pixelation along the bottom and right side of the clips. When the user decides to use these clips, which are letterboxed as a SD project for viewing, the artifacting is visible on a 4:3 TV OR an underscanned HDTV.
I entered a 20 second clip of Niagara Falls which displayed this anomaly into CB PAINT.
The scene automatically becomes a layer.
THEN....I simply RENDERED out the scene w/o adding anything.
The scene is back into the scene bin and ALL the artifacting is GONE...cleaned-up.
But wait...it gets better...much better.
I then entered in CB PAINT a SD scene with a slight digital dropout. When I executed the aforementioned, the clip was "smoothed-out" beter than the NOP process.
SO......We may be onto something as it relates to clearing up synch and other scene corruption problems by simply using CB PAINT.
STEPS:
