More then one I-Frame per 5sec

[Gloster10]

I use ssr with Ubuntu 22.04. After recording, there are some scenes to cut.
Is it possible to increase the given I-Frames by ssr of the recorded film, e.g.: to every 1sec. ?
I did leave the default settings (e.g.: 30f/sec, crf = 23, vorbis ...), but did not find any setting to increase the number of I-Frames.
