Thanks guys, tried those things, no joy. I just tried to do some color correction with the inbuilt 3 way corrector, apply a blur and could not get the canvas or my preview monitor to show the image effects, only can see it in the viewer vid window, seems I cant get any filters to work on there, I am using the same method of application as I always have, double click the clip in the time line, then throw the filter in the filter window of the viewer.
Earlier today I managed to apply some of the g filters by copying attributes to clips, which worked a few times then for some reason just stopped. Is there a render setting I need to change, I cant remember if the clips I managed to apply the filters to were in the same sequnce then I changed sequences and tried to do it to clips in a sequence that had different settings…
