So I'm pretty new to video encoding and I'm currently using FFmpeg to change the encoding of a video from H.265 to H.264 so it's suitable for the web.
The current syntax of the command I'm running is
ffmpeg -i input.mp4 -c:v libx264 -crf 51 -preset ultrafast -c:a aac output.mp4
I'm currently just trying to get this encoding to run as fast as possible and I'm not sure if there's any additional flags or settings I can tweak to make it run faster.
I've also tried setting the
fastdecode tune to see how that affects it but that didn't do much in terms of speed.
As far as I know, setting the
crf value and an
ultrafast preset are basically my options for speeding up the encoding, but are there any additional flags or settings I can use to help speed it up?
