Comment (by qianliang):
I find that adding filter "fps=20" while do convert operation, which would
fix this problem:
{{{
ffmpeg -i source_video_0.ts -filter_complex "fps=20" -vcodec libx264 -vb
1200k -maxrate 1800k -bufsize 3600k -r 20 -vprofile main -pix_fmt yuv420p
-flags +loop+mv4 -cmp 256 -partitions +parti4x4+partp8x8+partb8x8

-sc_threshold 40 -i_qfactor 0.71 -qcomp 0.6 -qmin 15 -qmax 45 -qdiff 4
-rc_eq 'blurCplx^(1-qComp)' -tune zerolatency -x264opts keyint=120:min-

}}}
