Thank you very much for the replies they have helped me make sense out of the results I have been getting
The video I was using in this project was grainy under exposed and generaly crap video. I understand the garbage in garbage out idea but it really looked bad on the DVD. Strobing pixels desaturated colours and the brightness went way up. I was using compressor.
Field order Auto
Two Pass VBR
Bit rate 6.4
Max Bitrate7.5 constant
Motion Estimation Best
Would using the constant bitrate would stop the strobing pixels?
