Hi,
Sorry to jump in on this thread but I'm having the same issue with the never ending "processing" of audio.
I'm just trying to make a silly fanvid and was using an old (2016) version of videopad on my Windows 10 laptop up until a few days ago. I was having some issues with the programing going "not responding" so decided to check for an update and saw I was long overdue. I've now updated to version 7.30 and it fixed that issue but since then the audio track (a song) that was playing fine before, just keeps constantly saying it's still processing so I can't properly preview my video to sync clips to the song because it keeps telling me it's waiting for the audio to process.
I've seen others on this forum try clearing the cache so have done that and un-installed and re-installed the software a few times but still no luck. I'm currently saving the project as a portable file. Is it ok for me to link that here or PM someone for help? I really want to finish this project.
Thanks
