How to record demonstration video

Machine: Mac Air without touchpad M1 2020

Capturing videos is a helpful skill for project demonstration.

If you’re using a Mac Air M1 2020 without a touchpad, QuickTime comes in handy, and the shortcut to save the video is “Command + Control + Esc”. Macs equipped with a touchpad offer more convenience due to the presence of a stop button.

Afterward, I utilized Canva to design the YouTube thumbnail, adjusting it to the dimensions of 1280 × 720 pixels.

Initially, I struggled to locate the right method for saving videos in QuickTime. I then turned to OBS but found its video quality unsatisfactory. Then I discovered the command to save high-quality videos in QuickTime, resolving my issue.

When I was working at ANU, a colleague was unsure how to record a video. My supervisor kindly suggested using QuickTime, showcasing a helpful and virtuous demeanor. I made a note of it for future reference to save time.

Editing such a short video is still quite a hassle, I can’t help but think:

One person’s power is very limited. Everyone adds firewood and the flames are high. This embodies the charm of entrepreneurship—collaborating with many people to achieve a goal. COW PTE serves as a lead through which we navigate all people and things, a label that connects us regardless of our locations, and a container that carries all the cherished memories.

One person’s power is unlimited. Every river echoes the ancestral calls of Indigenous people, every pathway resonates with the footsteps of Australia’s precursors, every stone testifies the trials endured by founders from the Spring and Autumn periods and the Warring States, and every day rejuvenates the splendor of our legendary tales.

Perched upon a rock, holding banners now aglow, I peacefully observe a herd of rams (Su Wu herding sheep).

Traversing scorching deserts, I listen to the harmonious chimes of camel bells. Upon glimpsing the tally (Fu) you bestowed upon me, I proceed with my journey (Zhang Qian’s mission to the Western Regions).

They say there’s someone in hell who daily pushes a stone up a mountain, only to start anew when close to reaching the summit (Sisyphus).

Some remain unchanged while some do evolve.

Even a butterfly’s fluttering wings can stir a tornado and even with a fulcrum, the entire Earth can be lifted, not to mention an ordinary person. Anyone can change the world.

Some transformed while some endure constancy.

“It’s you. Hurrem, it’s you who will never change.”

Mr. O’Hara said, “Everything changes, except for the land.” Conversely, my father said, “Even the land changes. Only you remain unchanged.”
