#!/bin/bash
# strict 2 is required to use the built in aac codec
# Fast start may not be needed when using the built in aac, but it is for h264
ffmpeg -i input.mov -vcodec h264 -acodec aac -strict -2 -movflags faststart output.mp4
# Better Quality, medium compression
ffmpeg -i input.avi -vcodec h264 -preset veryslow -crf 18 -acodec aac -strict -2 -b:a 240k -movflags faststart helvet.mp4
# Doing lossy X to lossy x264/aac right, crf 18 - 1 to account for compression artifacts
ffmpeg.exe -i input.avi -vcodec h264 -crf 17 -preset veryslow -acodec aac -strict -2 -b:a 240k -movflags faststart output.mp4
# Already have an h.264 stream? perfect, just copy it.
ffmpeg -i input.mkv -vcodec copy -acodec aac -strict -2 -b:a 240k -movflags faststart output.mp4
