With thanks to video.stackexchange.com/a/16686, here is a way to make that same padding white, as well as being another example of how to scale a mobile-originating video (in vertical format) correctly to horizontal as well as adjust the video and audio speed at the same time: ffmpeg -y -i "mobile_input.mp4" -filter_complex "[0:v]setpts=1.5*PTS,scale=1920:1080:force_original_aspect_ratio=decrease,pad=1920:1080:(ow-iw)/2:(oh-ih)/2:white,setsar=1/1,setdar=16/9[v];[0:a]atempo=(1/1.5)[a]" -map "[v]" -map "[a]" output.mp4 More info then the original question... but it may help someone..
