Field order??
Hi,
I have a question. I recently made a movie saved on to BetaSP PAL and sent it to the client. The client sent the tape to production company and they were told that the field that the field order on the first part of the movie is different from the second part of the movie. Because of that they suggested that I rendered the movie again to fix the problem, then put it on the tape again. There is countdown in the beginning of the movie and I suppose that what they are referring to as first part of the movie.
My problem is that I have no idea what they mean by “field order”. All I did was to make the movie in QT and sent it to postpro house to transfer it to the tape. Can anyone please tell me what the “field order” is?
Thanks bunch in advance,
Y

Right a frame of Standard Definition video is written into 625 line of pixels, Thats for PAL, for NTSC it is 525, but that is not the point. the fram is there for devidable by an A feild B feild make up . . . This is refered to as an “interlaced frame”
———————-A <<<----lines of pixels making up ----------------------b complete frame ----------------------A ----------------------b ----------------------A Now when you record to Video, you are writting our these lines onto the magnetic stock, you can write from top to bottom or from bottom to top... In other words because 625 is an uneven number you can write all the A lines ... (the A feild ) first or yo can write all the B lines (the B feild) First What it wsounds like happend is that your peice was going Ab ab ab ab then sudenly went ba ba babababa ... that will confuse a computer ... So when you re-output to from I am assuming after effects go into the settings and find where it says interlace or feild render ...or some such thing.. then choose a specific type AB ab ab or, bababa ... top to bottom or bottom to top.. Or ... you can get an application that will de-interlace or make your frams progressive a good app to do that with ... If you are working PC is TMPGencoder... alright? we kewl? good? later
