Let's say the flashback flashes in the protagonist's mind, what can you do besides graying the gutters, or graying the panels, or making the borders fuzzy? Is there a way to make it clear where the end and beginning is, and convey that the thoughts are violently flashing inside the mind of the protagonist? I couldn't find anything beside what's explained in the video.
It depends on the length. If it is an extremely long flashback, then you would want to use a new chapter that begins with italics. For example:
Chapter Two
Fifteen years ago:
I stood above the bodies of my parents, the room filled with a red haze.
Another way, if the flashback is short is to just use italics in a new paragraph. For example:
I looked around the apartment and saw that is was similar to a place that I had lived before.
"Jerry! Jerry!" My mom called out as she came out of the kitchen from our small one bedroom apartment
The simplest way is to label them. "Fifteen years ago." "Current day." etc.
