It's my first time using Premiere Pro so this may be a silly mistake, but I can't figure out how to fix it and Google hasn't been any help.
I've created a video (9 mins 15 seconds) that includes 3 different videos and a LOT of images. These all have transitions etc. When I playback the video on the timeline, it looks good and fits with the 6 different audio tracks (please see the image to show how they are). But when I export it, the first audio clip matches the video (60 secs) but the second audio-only works for a few moments before all audio drops completely for the rest of the video.
The audio clips are now .wav which gave me an additional few secs than when they were .mov
I've tried exporting a few different times but each export takes 3 hours and I don't have enough time to keep trying different export settings.
Please help me fix this and have an exported video that works as it shows in the timeline.
Your sequence is a multi-channel sequence with only 1 output - I can see this from the the "1" on the Timeline at teh left hand side under A3.
The simplest fix is to copy and paste everything in your timeline into a new Stereo sequence.
If you don't want to do that then you need to change the "1" to "2" and then in the track mixer panel, make sure all three audio tracks are a being sent to 1&2 (little button under the circular panning control.)
