I’m aware this is just v1, however I had no response in the primary topic for the v7 release and hope that if these issues are addressed sooner than later, v2 or v3 will be better overall.

VTS_01_2.MPG
This is the direct original MPEG-2 footage I worked from

VTS_01_2 Deinterlaced 50fps - File Used in Topaz.avi
This is the footage I loaded into Topaz and processed with Starlight Mini. It was deinterlaced with QTGMC into 50fps. It uses the lossless Lagarith codec.

Full_starlight_mini.mov
This is the resulting footage processed by Starlight Mini.

Problem Areas Enhanced.avi
I adjusted the levels and sharpness to bring out the problem areas I am seeing. Although now “exaggerated”, the blocks are still noticeable in “Full_starlight_mini.mov”.
