Hi I cant seem to find a way to additionally cut out the sides of my screen screen stage. I have tried using the effects mask but this doesnt work. I read somewhere that NCH were adding a polygon mask feature in 2015 but it still doesnt seem to be implemented. Whats the ETA on this and can anyone advise me on how to do this? note that I wanted also to clean the bottom edge of the matt. Mainly because it seems the resolution of pixelation is quite noticeable. Can you increase the edge resolution of the green screen. BTW I have used an actual green screen in this shoot. Thanks
I am trying to overlay two video clips. I found the answers in this thread to be really useful: http://nch.invisionzone.com/topic/25627-using-mask/ However the example there with the flying saucer is using a mostly dark coloured image on a fairly dark background. My video clips are taken outside and are quite light in colour, especially the sky area, and I find that I am seeing dark lines around my cut-out area. If I use feathering that actually makes it worse and I get thicker lines. I intitally thought the problem might be due to the lighting being very slightly different in the two clips, but I was able to reproduce the problem just using a solid white image overlaid on two tracks.Using the default reactangular mask I don't see the lines, but if you alter the mask shape they appear. Any ideas how I can remove or reduce these lines? Thanks Phil.
