Thanks for your comments! I think I will keep it interlaced then for the DVD.
I have found a
thread about aWarpSharp used to reduce chroma bleeding. I tried it after deinterlacing (TDeint+NNEDI) and it works very well. I'd like to use that filter for the final processing.
If I understand 2Bdecided right, I can use this filter (and similar progressive filters) like this:
SeparateFields() --> chroma-bleeding-filter --> Weave()
2Bdecided: It sounds as if I deinterlace for viewing on a PC (progressive) it is necessary to use double rate deinterlacing to keep the movement smooth?
