Other valid options are baseline, main-preset slow: sets encoding preset for x264 slower presets give more quality at same bitrate, but need more time to encode. vf "scale=4096:2160" // scaling the resolution codec:v libx264: tells FFmpeg to encode video to H.264 using libx264 library-profile:v high: sets H.264 profile to High as per Step 2. compression_algo raw // for uncompressed As jpeg2000 is a codec based on subsampling, the subsampling allows to achieve quite realtime performance using 50 or 25 size.
