TheFragranceOfDarkCoffee Ah thank you. I knew that FFMPEG can do all kind of stuff but I just want to avoid command lines hehhhh… I should learn this actually.
Edit: I just Binged “ffmpeg command for muxing jpg and mp3 into mp4 video” and got this:
ffmpeg -loop 1 -i input.jpg -i input.mp3 -vf "scale=1920:1080:force_original_aspect_ratio=decrease,pad=1920:1080:-1:-1:color=black,setsar=1,format=yuv420p" -shortest -fflags +shortest output.mp4
“This command will create an mp4 video with the name output.mp4 by combining the input.jpg and input.mp3 files. The -loop 1 option will loop the image infinitely, and the -shortest option will make the output video the same duration as the shortest input stream (either the image or the audio). The -vf option is used to scale the image to 1920×1080, pad it with black bars if necessary, and set the pixel aspect ratio to 1. The -fflags +shortest option is used to stop the encoding process as soon as the shortest input stream ends”
Looks good I guess??
