is there anything faster than "-preset ultrafast" in ffmpeg?

Question

I am using -preset ultrafast to adding watermark as fast as possible in the video.

I want to know just for knowledge or curiosity is anything faster than -preset ultrafast in FFmpeg to add watermark in the video very fast.

Answer 1

For the x264 encoder, there is no faster preset. See x264 --fullhelp for a list of possible presets.

The presets are also the same for x265.

Note that with ultrafast, you will be getting much larger files with lower quality than what you'd get if you could wait a little longer for the encode.

Hardware encoders such as NVENC (or others, see Wiki) can be much faster than x264. If live-streaming is what you're after, you should have a look at this.
