user11809: Extracting individual video fields is my previews question.
Based on the Mulvya's answer I can extract the top fields (only) or the bottom fields (only) individual.
Now, I need to extract the video fields In the following order:
TopField1 , BottomField1 ,TopField2 , BottomField2 ,....
Is it possible?
my source format: DV PAL 720x576i

user1871: Sure, you have to combine the field extraction with interleaving.
ffmpeg -i video.avi \
       -filter_complex "[0]field=top[t];[0]field=bottom[b];[t][b]interleave" -r 50 fld%d.png

where the r value is double the original frame rate (or the same as the field rate).
