Reduce Video Size with Script

Hier mein Shell-Skript zum erzeugen verschiedener Video-Formate für das Internet.

Achtung - Aspect-Ratio fuür mein iPhone - YMMV

html5-video-conv.sh

#!/bin/bash

usage(){
        cat <<EOF 1>&2
        usage: html5-video-conv.sh my-film.mov

        convert film to mp4, ogv, webm
        for use to embed there
        generates html snippet

EOF
        exit 1
}

INPUT_FILENAME="$1"
[ -z "$INPUT_FILENAME" ] && usage

# scale values optimized for iphone5s / 16:9 videos
#INPUT_FILENAME=my-film.mov

# remove filename extension
OUTPUT_FILENAME=${INPUT_FILENAME%.*}

#mp4
/usr/bin/ffmpeg -i $INPUT_FILENAME -vcodec libx264 -acodec aac -minrate 1M -maxrate 1M -b:v 1M -vf scale=854:480 ${OUTPUT_FILENAME}-480.mp4
