A video makes the page heavy

What you may see

A background video is tens of megabytes

Most likely cause

Videos are the biggest files on most pages; sending a large one to every visitor costs time and mobile data.

Check first (about two minutes)

How big is the file, how long is the video, and does everyone need it?

The fix prompt

What you type here never leaves your browser. The search runs on this page, and nothing is sent to a server or to an AI.

The exact error or what you see

What you did before it happened

Kept only in this browser, on this device. Keys and passwords are removed before anything is saved.

Prompt language

You are a senior web performance engineer who explains speed problems to people who are not developers. I am not a developer, so explain every step in plain words and tell me exactly which button, menu or command you mean. If you are not sure about something, say so; do not guess.

MOST LIKELY CAUSE
Videos are the biggest files on most pages; sending a large one to every visitor costs time and mobile data.

DO THESE STEPS, IN THIS ORDER
1. Shorten and compress the video (short loop, no sound, small resolution), provide a poster image, and load it only when visible or on good connections.
2. For long videos, use a video platform instead of hosting them on the site.
Stop and tell me if what you see does not match a step. Do not skip ahead.

CHECK THAT IT WORKED
- The page is much lighter and the poster shows right away.
Tell me exactly what I should see on the screen when it works.

DO NOT CHANGE
- Do not delete the original video.
- Anything I did not ask about: the design, the text, other pages, other settings or the data.
- Do not delete files, data or branches, do not reset or force-push, and do not rewrite history, unless you first show me exactly what would be lost and I say yes.
- Do not paste, print or ask me to paste a password or secret key into this chat. If one is needed, tell me which settings page of the right service to store it in.

WHEN YOU FINISH
Explain in simple words what you changed (file by file or setting by setting), why you changed it, and how I can undo it.

Paste it into Claude, ChatGPT, Gemini or Cursor, then follow what it says.

After you tried it, did it work?
