FFmpeg - combine 2 commands

Question

I have 2 commands as listed below.

Add intro image to a video

ffmpeg -y -loop 1 -framerate 10 -t 3 -i intro.png -i video.mp4 -filter_complex "[0:0] [1:0] concat=n=2:v=1:a=0" -c:v libx264 -crf 23 videoWithIntro.mp4

Add watermark to video

ffmpeg -y -i video.mp4 -i watermark_color.png -filter_complex "overlay=x=(main_w-overlay_w)/2:y=(main_h-overlay_h)/2"  videoWithWatermark.mp4

I was wondering is it possible to combine these into the 1 command?

Answer 1

Use

ffmpeg -y -loop 1 -framerate 10 -t 3 -i intro.png -i video.mp4 -i watermark_color.png -filter_complex "[0][1]concat=n=2:v=1:a=0[v];[v][2]overlay=x=(main_w-overlay_w)/2:y=(main_h-overlay_h)/2"  videoWithWatermark.mp4

I assume your videos don't have audio, else use

ffmpeg -y -loop 1 -framerate 10 -t 3 -i intro.png -i video.mp4 -i watermark_color.png -f lavfi -t 3 -i anullsrc -filter_complex "[0][1]concat=n=2:v=1:a=0[v];[v][2]overlay=x=(main_w-overlay_w)/2:y=(main_h-overlay_h)/2;[3][1]concat=n=2:v=0:a=1"  videoWithWatermark.mp4

Answer 2

The final command to get this working correctly is as follows ffmpeg -y -loop 1 -framerate 25 -t 3 -i 1920x1080_intro.png -i DSC_0002.MOV -i watermark_color.png -report -an -filter_complex "[1][2]overlay=x=(main_w-overlay_w)/2:y=(main_h-overlay_h)/2,setsar=1[v];[0]setsar=1[pre];[pre][v]concat=n=2:v=1:a=0" ../testing/videoWithIntroAndWatermark.mp4
