Comment:

 Input file intro.mp4 was encoded with x264 using constant quality (crf
 23), file outro.mp4 was encoded with x264 using adaptive bitrate (bitrate
 5000).
 I don't know if it is theoretically possible to concatenate such different
 samples with the concat demuxer if they are in the mp4 format (it works
 for Annex B).
