I seek a way to do simple bob (i.e. repeat fields at 2xFPS) with no

filtering. Can you help me?
-snip-
After so much time you still struggle a lot, buy some GUI tools and be
happy ever after.
Here's what I've tried so far:
-filter_complex
"split[a][b],[a]separatefields[c],[b]separatefields[d],[c][d]join"
-filter_complex
"split[a][b],[a]separatefields[c],[b]separatefields[d],[c][d]interleave"
-vf "separatefields,shuffleframes=0 0,weave"
-vf separatefields,scale=720x480
-vf separatefields,scale=w=iw:h=2*ih
-filter_complex "split[a][b],[a]separatefields[c],[c][b]scale2ref"
Do you want interlacer or deinterlacer? It is very unclear from your
subject what you need.
Simple bob deinterlacer takes every single field and than interpolates
missing fields with bilinear interpolation iirc.
I think that bob just separates fields (e.g. [720x480] -> [720x240][720x240]), then line doubles
(e.g. [720x240][720x240] -> [720x480][720x480]). When it is played back, horizontal lines in the
video appear to bob up and down (but at 60Hz, that's not very noticeable).
