I ran the same file through the AWS transcoder – one is 720 and the other is 1080.
Before the transcode the file was a 1920×1080 file at 3.3GB
After the AWS transcoder the 720 was 244.4MB and the 1080 was 530.6MB
They both rendered a file at about the same size at 413MB
Is there a different in quality? Which do you prefer?
