We become our own worst critics. I find that there is always a malfunction, a figure that fell over, some lights that I forgot to turn on, a tripod other piece of equipment or sometimes even my dumb face that spoil the video. It is an issue to me, but I have asked others, including my wife, and they don't even notice it.
I always say, it wouldn't be one of my videos if I didn't make at least 1 mistake.
Keep up the good work, you are doing a great job. We are pushing our trains beyond their limits and recording it for others to enjoy.
