ffmpeg how to watermark and concatenate in one command

If you were in my boat you were frustrated that you had to double encode, eg. one separate encode for watermark and a separate from concat and it's not easy to figure out this with ffmpeg on your own.  However it is a nice way to save time!

ffmpeg -i file1.mp4 -i file2.mp4 -i file3.mp4 -i watermark.png -filter_complex "[0:v]setpts=PTS-STARTPTS[v0]; [1:v]setpts=PTS-STARTPTS[v1]; [2:v]setpts=PTS-STARTPTS[v2]; [v0][0:a][v1][1:a][v2][2:a]concat=n=3:v=1:a=1[v][aout]; [v][3:v]overlay=W-w-10:10[vout]" -map "[vout]" -map "[aout]" -crf 20 output.mp4

Of course file1.mp4 file2.mp4 file3.mp4 are your source videos you are concatenating (in that order) and the watermark.png is your watermark.   The overaly W-w-10:10 sets your mark on the top right.

To overlay on the bottom right: W-w-25:H-h-25

I also added "-crf 20" as the default is 23.  In general the higher the number the faster the encode but lower the quality.  I found 20 is a good medium.  A good test is that if your output video is smaller than your input you have lost quality.  Try to experiment with crf until you get a size the same or slightly larger than your original input.
