Hi Rafael!

Thanks for your advice. I converted my H:264 files to Apple ProRes 422 (HQ), would your advice be to use 5DtoRGB to do this convention.

Thanks again for your help

Hi rafael,

Thanks for your reply.

After some trial and a lot or error experimenting I found that the problem lay with the way I was converting the H264 files in compressor. With the Pro res files I was editing with when I was converting them in compressor I unticked Enable 4:4:4 chroma filtering. So I have just exported to sample files with the Enable 4:4:4 chroma filtering ticked, then I used the end of the same time line I had been editing in to do a test. I placed one clip on the the bottom track and added a filter then I placed the other clip over the top as if a cut away. then I rendered and exported this session of the timeline as a self contained movie and the problem of the color shift had gone.
