[FFmpeg-user] Converting .mov files playable on html5 players..but very slow

[Dani A]

I am using the below command to covert the .mov files to play html5, but it takes so much time..Is there another way to convert those files so they can play on html5 players but fast to convert...
ffmpeg -i input.MOV -vf scale=720x406,setdar=16:9 -c:v libx264 -profile:v main -crf 20 -movflags faststart output.MOV


Is there a faster codec to use compared to the libx264?
