Hello! I've been a long time user of Applian products. Just recently had a need to join a bunch of 1 minute long MP4 video files into one file. My security camera records 1 minute clips and I needed to join a bunch of them into a seamless video file with no encoding and thought this would be perfect.I used the joiner option. I was able to do this and joined 60 one minute files into an hour long video file that worked BUT there is no audio? When I import them it shows there is no audio channel in the file but there most definitely is. I tried anyway but it didn't work... video is fine but no audio. I looked for a setting but could find nothing that I was doing wrong. Any suggestions? Thanks!
