I have been trying to edit 4K footage in VMS 15. The original footage looks fine but once imported into VMS the footage seems to corrupt. There are visible horizontal tears or horizontal lines of pixelation across the footage when rendered. If I delete and re-import the footage the problem may go away but reappear elsewhere. It's hard to see whether the problem is visible in the trimmer but is very obvious when rendered.
I have tried rendering using GPU acceleration and without. Using Magix AVC/AAC MP4 format.
I have tried 'Reduce Interlace Flicker'.
None of these seem to work. Any ideas as to how I could solve this?
