This FFmpeg command converts an image and audio into a WebM video.
This command is optimized for creating a web-friendly video that combines a static image with audio, prioritizing fast encoding speed over maximum quality.
Input Options
-loop 1: Loops the image continuously (makes a static image last for the duration of the audio)-i image.png: First input - the static image-i audio.mp3: Second input - the audio file
Audio Encoding Options
-c:a libvorbis: Use Vorbis codec for audio-b:a 128k: Set audio bitrate to 128 kbps
Video Encoding Options
-c:v libvpx-vp9: Use VP9 codec for video-tune psnr: Optimize for PSNR (Peak Signal-to-Noise Ratio) quality metrics-g 7500: Set keyframe interval to 7500 frames-keyint_min 7500: Set minimum keyframe interval also to 7500 frames-crf 40: Set Constant Rate Factor to 40 (higher value means lower quality but smaller file size)-pix_fmt yuva420p: Use YUV420P pixel format with alpha channel-threads 4: Use 4 CPU threads for encoding-speed 5: Set encoding speed (higher value is faster but lower quality)-deadline realtime: Use realtime encoding mode (faster but lower quality)
Output Options
-shortest: End the video when the shortest input ends (likely the audio in this case)-movflags +frag_keyframe+empty_moov: Optimize for web playback-f webm: Force WebM container formatoutput.webm: Output filename
