Record clips on xbox?

I make clips of cod mw from time to time and I have set the recording time to 15 seconds, i.e. The last 15 seconds are recorded.

Every time I want to look at them, they are only 5 seconds long instead of 15. Otherwise everything worked perfectly, but not recently.

Nothing has been changed in the settings!

Hope to get plenty of answers
