Hoping someone might be able to shed some light here for me, I'm pretty new when it comes to video editing. About a month ago I had used the Templates in Video Pro X to do an Intro and Outro for my YouTube. Everything worked perfectly, exported to MP4 and I have been using them on my videos. However, I decided recently to update my Intro/Outro with my own artwork, but I started getting a weird popping sound after exporting to MP4. Tried exporting HEVC also, same result.
Thinking it might have been the audio clip I was using, then I tried just using the same template as before with a different font, I noticed the volume of the sound was a lot lower compared to my original ones (used same template) and the popping was still there, the only thing I had touched or changed was the font (it did the same with the default font too). I've tried exporting with Best Quality, higher bitrates, no luck.
Nothing has changed, my hardware is exactly the same as when I created the original Intro/Outro and the settings are the same too. I have attached a screenshot of what my default settings are and 2 versions of my Outro (Original and the most recent one that has the weird popping sound). Even the overall sound quality is better in the original too.
