There is no native videoin, elliots image pack is 32bit.
I am working with beta34.1
dx9todx11 texture is an option, but it feels a bit like a hack and it is my impresion that the shared texture might result in stuttery imagery at higher resolutions
Sunep, between the video texture and the dx9-dx11 I usually have a changeformat node to steady out the frame transfers. It means using more GrFxcard memory but it seems to guarantee I get a steady output.
