Argh! I keep making mistakes. I'm working too quickly. You see, I had 2 differing versions: one
using 'telecine=pattern=5' and one using 'telecine=pattern=46'. They tried to do the same thing, but
by differing methods (differing filter graphs). It's really easy to get them mixed up.
Here is a sketch of the original graph:
split[A] select='not(eq(mod(n+1\,5)\,3))' [C]interleave
[B]split[E]select='eq(mod(n+1\,5)\,2)'[G]blend[D]
[F]select='eq(mod(n+1\,5)\,3)'[H]
Here is a sketch of the graph with 'blend' inputs reversed:
split[A] select='not(eq(mod(n+1\,5)\,3))' [C]interleave
[B]split[E]select='eq(mod(n+1\,5)\,2)'[H]blend[D]
[F]select='eq(mod(n+1\,5)\,3)'[G]
Here are the command lines (as a unified script):
: Run original filter chain
SET FFREPORT=file=FOO-GH.LOG:level=32
ffmpeg -i %1 -filter_complex
"telecine=pattern=46,split[A][B],[A]select='not(eq(mod(n+1\,5)\,3))'[C],[B]split[E][F],[E]select='eq(mod(n+1\,5)\,2)'[G],[F]select='eq(mod(n+1\,5)\,3)'[H],[G][H]blend[D],[C][D]interleave"
-map 0 -c:v libx264 -crf 20 -an -sn "C:\AVOut\FOO-GH.MKV"

-map 0 -c:v libx264 -crf 20 -an -sn "C:\AVOut\FOO-HG.MKV"
Here are the logs in the same order:
