FFMPEG: How to Encode for Searchable Video with High Keyframe Interval

Question

I am looking for a ffmpeg comand which is best used if I control the mouse control video on "requestAnimationFrame". Basically, it should be quickly distorted and encoded with a high keyframe interval. I can’t cover what parameters help in fast and high key frames.

thanks! Johnny

If you are encoding x264 (mp4) try ( docs ):

ffmpeg -i file -c:v libx264 -x264opts keyint:25 [preset/rate control options] out.mp4 

If you are encoding vp9 (webm), try ( docs ):

 ffmpeg -i file -c:v libvpx-vp9 -g 25 [speed/rate control options] out.webm 

Both teams will post a new keyframe every 25 frames. If you want more than that (for example, one keyframe in each frame), then you probably don’t need compression, how much you care about speed, and maybe you should look at codecs only inside one type, such as FFv1 .
