The idea
Vimeo, embedded with the right parameters, keeps a creative director on your portfolio; YouTube's default embed sends them to other creators' videos and signals hobbyist. The showreel is the first thing a creative director sees and the last thing they remember. How it loads and plays is as important as what is in it. Most freelancers default to YouTube because it is free, but YouTube can show related videos from other creators after your reel ends and displays YouTube branding throughout: the logo, the progress bar, the suggested videos. To senior buyers who see hundreds of portfolios, that can signal hobbyist. Vimeo is the professional standard for many creative portfolios: viewer stays on your site, and current paid plans may add analytics so you can see whether a creative director watched your reel before you follow up.

Here is the before and after: A YouTube embed (a small block of code that drops the video player into your page) with default settings ends with a grid of other creators' videos and YouTube's red logo over your work. A Vimeo embed with the four parameters in the exercise below (responsive width, a 16:9 ratio, no autoplay with sound, no related videos) ends cleanly, keeping the viewer on your portfolio. The embed code is the same short snippet either way; only the parameters differ.
Now try it: run the exercise prompt below with your Vimeo or YouTube URL, specify the four embed parameters (responsive width, 16:9 ratio, no autoplay with sound, no related videos), and ask Claude to tell you exactly where in your HTML file to paste the result. Test the URL in incognito before embedding: a private video shows a lock icon instead of your reel.

Watch out for
Paste this into Claude
[Paste your Portfolio Brief here: the paragraph you wrote in Lesson 0] --- I have a portfolio HTML file you helped me build. I want to make sure the showreel section is embedded correctly. My showreel URL is: [your Vimeo or YouTube URL] My hosting platform: [Vimeo / YouTube / Cloudflare Stream / other] Please give me the correct iframe embed code for this video with these settings: - Does NOT autoplay automatically when the page loads - Does NOT show related videos or third-party branding at the end - Has a responsive width (fills its container on any screen size) - Has a 16:9 aspect ratio - Shows player controls so viewers can pause and scrub Then tell me exactly where in my HTML file I should paste this code: what line to look for, and what to replace. Also tell me: for my type of work, is there a reason to upgrade to a paid Vimeo plan rather than using the free tier?
