Answer 1

1. Create the file resize_video.sh, with the code below
2. Open the terminal, run the command: sh resize_video.sh

This script, will convert videos as needed by the AppStore.

INPUT_VIDEO=app_preview.mov

mkdir -p 6.5
mkdir -p 5.5
mkdir -p 12.9

WIDTH=886
HEIGHT=1920
OUTPUT_VIDEO=6.5/app_preview.mov
rm -f $OUTPUT_VIDEO
ffmpeg -i $INPUT_VIDEO -qscale 0 -r 24 -y -vf scale=$WIDTH:$HEIGHT,setsar=1:1 $OUTPUT_VIDEO

WIDTH=1080
HEIGHT=1920
OUTPUT_VIDEO=5.5/app_preview.mov

rm -f $OUTPUT_VIDEO
ffmpeg -i $INPUT_VIDEO -qscale 0 -r 24 -y -vf scale=$WIDTH:$HEIGHT,setsar=1:1 $OUTPUT_VIDEO

WIDTH=1200
HEIGHT=1600
OUTPUT_VIDEO=12.9/app_preview.mov

rm -f $OUTPUT_VIDEO
ffmpeg -i $INPUT_VIDEO -qscale 0 -r 24 -y -vf scale=$WIDTH:$HEIGHT,setsar=1:1 $OUTPUT_VIDEO
