Video for TV Well, maybe is interlacing but not only that, I was refering also to what appears to be "not clear/ grain" video. > you may see combing effects at fast motion scenes.

I am doing more testings with more options. The video appearance of my first few works was not good (grained ??? maybe that is not the appropriate English word; not good resolution ?? as seen at the screen).
