Convert a Single PNG into a Five-Second MP4, Preferably via FFmpeg

[raywood]

How can I convert a single PNG into a five-second MP4? High quality is important. I would appreciate an FFmpeg solution but will use alternatives.

Never mind. I already knew the answer. I used IrfanView's Slideshow > output to video.

ffmpeg -loop 1 -i image.png -t 5 -c libx264 -crf 18 -vf fps=24000/1001,scale=1280:720 output.mp4

where
-t is the duration in seconds
-c is the video codec, in the example x264(avc)
- crf is the quality (0-28, lower is better)
fps is the framerate, in the example 23.976 (24000/1001)
scale is the resolution, in the example 1280x720

Adjust the parameters as required.

Thanks! Looking forward to trying it.

But it is better to add tune for stillimage https://video.stackexchange.com/questions/34800/encode-still-image-video-effectively-in-ffmpeg and add -keyint infinite https://forum.videohelp.com/threads/381403-x264-and-still-images#post2467673
