ffmpeg creating a boomerrang video I'm trying to use ffmpeg to create a "boomerrang" video. Where it would take in one video, play that video forward, then play it backward, and once more forward all at 1.5x speed. I'm been able to do the forward/backwards process with this command:

ffmpeg -y -i input.mp4 -filter_complex [0]reverse[r];[0][r]concat,setpts=0.5*PTS output/boomerrang.mp4

But I've been unable to get that final 3rd play with the video playing forward. I'm assuming I would just need to concat the video on the end but I'm not really sure how to do that.
You just need to add the original input to the concat.

ffmpeg -y -i input.mp4 -filter_complex [0]reverse[r];[0][r][0]concat=n=3,setpts=0.5*PTS output/boomerrang.mp4
