Left questioning his team's toughness after their round six loss to Melbourne, Dockers coach Justin Longmuir resorted to using match footage to illustrate where they had gone wrong.
A clip of a lethargic Clark allowing Demons star Kysaiah Pickett to kick a goal on him was included in the package.
The mortification left a deep impression on the 24-year-old.
Longmuir achieved his desired outcome when Fremantle rebounded from a week of criticism with an 18-point win over Adelaide on the weekend.
"We showed a few clips last week of controllable things, which was a little bit of a lack of effort, little bit of a lack of care at times," Clark said on Monday.
"I was in one of those clips and I never want to see myself in one of those ever again.
"I don't think I need to look past any more than that to be able to have the motivation to repeat what we did (against Adelaide)."
Asked about the clip specifically, Clark joked: "I'm not going to touch on it if you haven't seen it.
"Nah, it was just the first clip of the (Melbourne) game where Kozzy Pickett got in front of me and kicked a goal and I wasn't physical enough.
"Trying to call myself a senior player now, I've got to be better than that.
"It's one of the first five minutes of the game, so it probably set the tone for the day, and looking back on it, was pretty embarrassing."
The video compilations are set to become a mainstay as Fremantle (4-3) look to break into the top eight when they play St Kilda.
"We still don't want to overplay our performance (against Adelaide) on the weekend and give everyone a pat on the back and say everyone was perfect," Clark said.
"Because the reality was we weren't and it's footy, no two games are the same.
"Out of the weekend, we still had a clip that, as a group, we weren't happy with.
"That's the maturity that we're starting to get to, is we're able to address those things, and we're able to have players get up and hold each other accountable - that's the exciting part."
