I am working on a client's trademark logo and I need help with the final export. The clip is HDTV 1080 25 format in ae. The rest of the settings Iv left as default. I have created part of the logo in Maya and then imported the logo as a tiff sequence into After Effects for some compositing. When I export the clip using 'make movie' as H.264 or HDV, the clip would degrade significantly in colour quality for the final compression. So, the background would split into different bands of colour. However, when I use an intermediate format like pro res, it comes out the way I see it in ae. So the colours don't band.
I want to know, what can I do to stop the banding? or What other codecs can I use to avoid the banding and can be used for the final compression?
