Comment (by degradox):

 Using both `asetpts` and `-avoid_negative_ts 2`, logs is `dup=115
 drop=837`, video ends 5 seconds before audio:

 {{{
 % ffmpeg -y \
   -i input_good.mp4 \
   -filter_complex "\
     [0:v]scale=1920:1080:force_original_aspect_ratio=decrease,setpts=PTS-
 STARTPTS [scaled_main]; \
     color=c=black at 0:s=1280x720:d=10000 [blank_overlay]; \
     [blank_overlay]format=gray [mask_trim]; \
     [blank_overlay][mask_trim]alphamerge [overlay_stream]; \
     [scaled_main][overlay_stream]overlay=x=main_w-overlay_w-0:y=main_h-
 overlay_h-0:eof_action=pass:shortest=0 [outv]; \
     [0:a]asetpts=PTS-STARTPTS [outa]" \
   -map "[outv]" -map "[outa]" \
   -c:v libx264 -profile:v high -level:v 4.2 -pix_fmt yuv420p -r 60 -b:v
 600k -preset fast \
   -c:a aac -b:a 80k -ar 48000 -ac 2 -fps_mode cfr \
   -avoid_negative_ts 2 \
   -nostdin output_desynced.mp4
 }}}

 Same exact results using `-avoid_negative_ts 1` instead of
 `-avoid_negative_ts 2`.
