That’s great thank you .
To be honest the “judder issue ” is fine as its not there when my project is burnt onto a bluray .
The quality issue I need to look further into and like you say experiment . I will check that my project is not been converted into 50p in fcpx etc .
What is the best codec to use in fcpx for the best quality ? Time and size are not a worry as I would just rather get the last grain of quality .
Thanks again for your help
