Problem with making a csgo clip

Hi,

I am using the same technique for making csgo clips.

The problem now that I am having is, for some reason, that the recorded sound file and the images that I made from the game demo, well, they have a difference of two seconds. As in, the sound file is 2 seconds more than the duration of the images.

I am importing the images as an image sequence, and importing the .wav file.

Why is the sound file bigger?

Is this a problem with recording the images, and the sound from the demo of the game or is it a problem with adobe premiere?

Like I said, I am following the same technique as i've made older clips, and this problem did not used to be there.

If you need me to explain more, please let me know.

Thanks
