Hi Jon,
Thanks for your speedy reply!
Just tried what you suggested (new sequence @720×300 square pix > drop HD seq in + scale to frame size)…..
I am now getting the ‘tearing’ problem in the preview of timeline. HOWEVER – when I select the motion tab in effect controls – i.e: select the clip’s transform handles – it looks as it should. As soon as I deselect Motion it goes back to nasty white noise!
I then switched off Mercury GPU acceleration and then rendered the now red work area – all fine!?!
So looks like a Mercury/CUDA/Quadro problem?
Anyone had this before? The quadro has been amazing for me throwing multiple formats together and editing/scaling/messing with clips on the fly, so ideally don’t want to have to go back to rendering every time I want to view an output.
