Hi, I don't edit video often, rarely ever. Recently got a gopro hero 8. Shot a video at Disneyland of a water show, with lights, and sound. Really cool show. The show was really long, 20+ mins. I got tired of holding the camera for that long. So i shot about half the show. However, they are in 3 clips. I want to add a title in the video. I already got the title working fine. I have the 3 clips cross dissolved transitions in. However, anytime i export it, the sound goes to crap. Doesn't matter what settings i choose to export it in. I can choose the highest settings, or the worst, the audio is not the same as the original. I haven't touched any sound settings. I tested all the different sound settings in imovie, and that doesn't help.
So I watched one of the 3 clips in imovie, once imported into the imovie app, and sound automatically changes without even doing anything. So once imported the sound changes. Is there a setting in imovie, where i can just keep the original audio? Again, the original audio changes once its imported into the app, without touching anything. Everything is at default settings in imovie.
Software is most updated version of Catalina, and imovie.
