Unwanted "clicks" when rendered clip commences

[Phil]

Hello,

I've noticed this a few times in different projects after rendering....

I always start my clips with the black color insert but as soon as the first video clip fades in, there are 1 or 2 unwanted audio "clicks", "pops" or "scratch" noises.

I then noticed this with a song on a different project as it started first - so I know it wasn't anything to do with my video files.

Lately, I commenced a short film using one of Corel's own titles against the black background and again, as one word entered the screen, a double click, then as the second another click or two!

What is happening and I how do I eliminate it?

After a short experiment, it seems an .m4a audio file was causing the clicks. I converted it to a WAV file and it's fine now.
