[Grzegorz Kwiatkowski] "The technical requirements of my station was 1080/50i... Do I have to shoot interlace or I can shoot progressive?"

You should confirm the following.

Most cameras can shoot 25p. At 1080, they can record what is called Progressive Segmented Frame, of psf. This means that the complete frame captured by the camera is recorded as two fields. The resulting video is 1080 50i, but it looks like 25p.

This is not a new trick: standard-definition DV cameras also used it to record 25p.
