How do I speedup encoding of a video that has just 1 static frame with ffmpeg and lib264 library?

Question

I'm making mp4 (libx264 + aac) videos that have just one static image throughout the whole video. It's basically a narrated text with a nice background.The question I've is how could I speed up encoding of such videos? Currently the videos are encoding at 50fps which is very, very slow. I can only encode 2000 videos on a single computer in one day.Any particular settings I could specify to ffmpeg or lib264 library to suggest that there is no motion, and it's just a single image that has to bFor comparison, I was doing .avi (divx + mp3) videos before I moved to mp4, and I was able to encode 6000 - 8000 videos per day.

Answer 1

First, I would lower your frame rate to the lowest possible setting. The encoder doesn’t know that each frame is the same, so you have it encoding a image to be played 50 times a second.

Second, lower your video bitrate. You don’t need something high for a static image.

Lastly, you can use a lower resolution. If you’re making videos for most video platforms, you can encode at 720p and still get a good result.

Holy moly, thousands of videos a day!!
