Deinterlacing outputs small file only

Looked at the debug output:
the Avisynth script:

looks fine.

looks fine too and finshed without reporting any issues:

seems correct and also finished without a problem:

Muxing call seems fine too:

I strongly advice NOT to use .avi for H.264 as container, better use .mkv or .mp4, multiple b-frames, open-gop and similar are 'tricky' in .avi and some players will not support it.

from the looks of it, ffmpeg does not like the audio.

Can you share the source file with me, so I can try to reproduce the issue?

Ps.: As a side note, you might want to switch to Vapoursynth or Avisynth 64bit, instead of using 32bit Avisynth.
