thank you so much for you response.
Not only the imported video has the interlacing but alos some image position animations I did inside FCPX is interlaced as well.
Is there a way to verify that this is not from the frame rate? also this must be in 1080i for the TV network can I use compressor 4 to make sure frame rate etc is done properly so it is 1080i and the animation looks fine on TV? can you please assist me with this?
