Solved - The problem with ticking on audio track of video recording on Canon X405F
After some testing, I found the cause of the electrical interference 'tick' on the audio track of my video recordings.
It's caused by the digital zoom. When I turn off the digital zoom setting inside my Canon X405F video camera, the tick goes away. Now I use only the optical zoom, and if I need to 'zoom' I do in by cropping in post production.
I hope this helps you.
