Generic Optimized Command
Good for daily use, archiving, and streaming.
ffmpeg -i input.mp4 -vf "scale=w=1080:h=1920:force_original_aspect_ratio=decrease,pad=1080:1920:(ow-iw)/2:(oh-ih)/2:color=black,setsar=1:1" -crf 18 -preset veryslow -threads 0 -tune fastdecode -movflags +faststart output_optimized.mp4
Note:Combines scaling, padding, high quality encoding (
-crf 18), slow preset for better compression, and web optimization flags.Web Optimization (Faststart)
Move metadata to start of file for faster playback.
ffmpeg -i input.mp4 -c copy -movflags +faststart output.mp4
Note:
-movflags +faststart moves the moov atom to the beginning of the file, allowing the video to start playing before it is fully downloaded.Tune for Fast Decode
Optimize for playback on lower-end devices.
ffmpeg -i input.mp4 -c:v libx264 -tune fastdecode output.mp4
Note:
-tune fastdecode disables some advanced encoding features to make the video easier to decode on older devices.VIDEO API
