To shoot a video, more like explaining an event on how you spent your day. It can take one about 10 minutes to express yourself and what is left would be to edit the video.
Just like my video below which is about 4 mins.
I was in a rush to school that early morning when I made this video, so I was making the edits on the video while I was in class.
Compared to writing, I would have to seat down and do the whole job. I cannot do it in a haste, my mind has to be in a calm taste if not, I would not connect to heart and would end up writing rubbish containing paragraphs that don't link properly.
But video, I know what I want to say and I just express myself out.
Coming to guitar covers, I cannot do this in a haste at all because I use at least 4 hours alone trying to shoot my video haven't even edited it.
