[FFmpeg-user] Decombing via screening - 'tblend' bug (?)

[Mark Filipak]

This:

ffmpeg -i IN -filter_complex 
"telecine=pattern=5,split[A][B],[A]select='not(eq(mod(n+1\,5)\,3))'[C],[B]select='eq(mod(n+1\,5)\,3)',split[E][F],[E][F]blend[D],[C][D]interleave" 
OUT

outputs 598 frames

This:

ffmpeg -i IN -filter_complex 
"telecine=pattern=5,split[A][B],[A]select='not(eq(mod(n+1\,5)\,3))'[C],[B]select='eq(mod(n+1\,5)\,3)',separatefields,scale=height=2*in_h:sws_flags=neighbor,setsar=1,tblend[D],[C][D]interleave" 
OUT

outputs 716 frames

Now, does that look consistent to you?

But of course, since I can't read, and I'm always wrong...
