Scale2ref then join two video clips using ffmpeg
1
I have two video (with audio) clips that I want to join. The first clip has the following format:
Stream #0:0(und): Video: h264 (High) (avc1 / 0x31637661), yuv420p, 1280x720 [SAR 1:1 DAR 16:9], 358 kb/s, 25 fps, 25 tbr, 12800 tbn, 50 tbc (default)
Metadata:
handler_name : VideoHandler
Stream #0:1(und): Audio: ac3 (ac-3 / 0x332D6361), 48000 Hz, stereo, fltp, 192 kb/s (default)
Metadata:
handler_name : SoundHandler
Side data:
audio service type: main
And the second:
Stream #0:0(und): Video: h264 (High) (avc1 / 0x31637661), yuv420p, 320x240, 88 kb/s, 8 fps, 8 tbr, 16384 tbn, 16 tbc (default)
Metadata:
handler_name : VideoHandler
Stream #0:1(und): Audio: ac3 (ac-3 / 0x332D6361), 11025 Hz, mono, fltp, 96 kb/s (default)
Metadata:
handler_name : SoundHandler
Side data:
audio service type: main
I want to join the two clips; the first followed by the latter while keeping the format options of the second clip.
Based on reading the documentation and other questions I have reached the following command:
ffmpeg -i secondClip.mp4 -i firstClip.mpg -filter_complex "[1:v:0][0:v:0]scale2ref=oh*mdar:ih[2nd][ref],[2nd][1:a:0][ref][0:a:0]concat=n=2:v=1:a=1[outv][outa]" -map "[outv]" -map "[outa]" output.mp4
This gives the following errors:

The two videos don't have the same aspect ratio. So you'll need to either stretch or pad one of the videos.
