x264: Optimal settings to have i-frames coincide with shot boundaries?

I would like to encode a video using x264 in such a way, that the keyframes (a.k.a. i-frames) are coinciding with shot boundaries (a.k.a. cuts).

for testing, I used the following encoder settings (reference: http://www.chaneru.com/Roku/HLS/X264_Settings.htm):

keyint=500:min-keyint=10:scenecut:40

but from the looks of it scene changes are ignored entirely, and keyframes simply inserted every 500 frames.

enter image description here

scenecut:40 being the default value, is my result expected behavior? or is it an indication, that something is not quite right?

thanks a lot in advance

edit:

the complete encoder settings look like this (in handbrake):

TL;DR:

it was a typo :|

Solution

  • From your settings screenshot it looks like it result in disabling of scenecut (scenecut=0 in x264 Unparse) because you used : as separtor of parameter name and value for scenecut instead of =. So either change your additional params to:

    keyint=500:min-keyint=10:scenecut=40

    or remove scenecut from it at all i.e.:

    keyint=500:min-keyint=10
