I know about presets but faster presets lose the video quality. Are there any hardware requirements I need to consider? Or are there any settings that I need to tweak? And lastly where do I place the -threads flag to encode video (before input or after input), I saw topics on thread but they were confusing.
This is the command I am using now: ffmpeg -i input.mp4 \ -codec:v libx264 -tune zerolatency -profile:v main -preset medium -crf 23 -maxrate 1000k -bufsize 10000k -s hd720 -codec:a libfdk_aac -pix_fmt yuv420p -movflags +faststart -threads 4 highoutput.mp4 \ -codec:v libx264 -tune zerolatency -profile:v main -preset medium -crf 23 -maxrate 500k -bufsize 5000k -s hd480 -codec:a libfdk_aac -pix_fmt yuv420p -movflags +faststart -threads 4 lowoutput.mp4 _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user
