This did not help I’m afraid.

Smaller files on this link: http://we.tl/nAsyxy4Pt9 (6MB for 1 input and 2 output files - one correct output file from ffmpeg1 and the incorrect output from ffmpeg2)


Encode command for ffmpeg2: 

ffmpeg -i "Input_3.mov" -map 0:v -map 0:a -vf "scale=720:576:1,pad=720:608:0:32:black" -c:v mpeg2video -r 25 -pix_fmt yuv422p -minrate 50000k -maxrate 50000k -b:v 50000k -video_track_timescale 25 -intra -flags +ildct+ilme+low_delay -intra_vlc 1 -non_linear_quant 1 -ps 1 -qmin 1 -qmax 3 -top 1 -dc 10 -bufsize 2000000 -rc_init_occupancy 2000000 -rc_buf_aggressivity 0.25 -tag:v mx5p -bsf:v imxdump -c:a pcm_s16le -ar 48000 -y "Output_IMX_ffmpeg2.mov”
