How to Lengthen Video Reference in Adobe Audition 2020

Hi

I’ve been learning to use Adobe Premiere Pro 2020 and Adobe Audition 2020 over the last few months.

I’ve created a ‘home movie’ of a family holiday in Premiere Pro, which goes for 1 hour and 40 minutes.  I’ve successfully exported it as an MP4 file which works perfectly.

I’ve imported the MP4 into a multitrack in Audition and I’m putting audio tracks to match the video.

Unfortunately, my MP4 video reference in the multitrack is cut to 45 minutes.

Can someone please help me?  I need to lengthen the video reference to the actual length of my MP4 file (1:40:51)?
