If all else (with ffmpeg) fails, Avisynth's Interleave filter should do the
job:

"Interleave
"Interleave (clip1, clip2 [, ...])

"Interleave interleaves frames from several clips on a frame-by-frame basis,
so for example if you give three arguments, the first three frames of the
output video are the first frames of the three source clips, the next three
frames are the second frames of the source clips, and so on."
