- FFmpeg is a free and open-source software project consisting of a large suite of libraries and programs for handling video, audio, and other multimedia files and streams. At its core is the FFmpeg program itself, designed for command-line-based processing of video and audio files.
In this video I try to show how bitrate affects the file size and visual quality of a video. The FFMPEG command used in the video is attached below.
From RAW to MP4 with bitrate adjustment:
ffmpeg -re -f rawvideo -pix_fmt yuv420p -s:v 1920x1080 -i input.yuv -c:v libx264 -s 1920x1080 -flags cgop+ilme -sc_threshold 1000000000 -b:v 5M -minrate 5M -maxrate 5M -bufsize 3M -r 25 output.mp4
From MP4 to MP4 with bitrate adjustment:
ffmpeg -i input.mp4 -c:v libx264 -s 1920x1080 -flags cgop+ilme -sc_threshold 1000000000 -b:v 5M -minrate 5M -maxrate 5M -bufsize 3M -r 25 output.mp4
Muchas gracias! Finalmente un tutorial que explica un poco de los fundamentos del cambio de tasa de bitrate 😶🌫
Is there a way to set avg bitrate like on handbrake in ffmpeg?
