When pasting a video into an LLM would actually help.
Five real situations where describing a moment in text falls flat and a 10-frame grid does the work for you. Each card has a working demo — open the VideoContext widget and record the bug as it happens.
Recording tip: the bugs below are real. Try each one before grabbing frames.01
An intermittent UI bug you can't reproduce in words
A dropdown closes itself when you scroll the page, but only sometimes. The bug depends on timing, focus, and whatever the page is doing in the background. Try to describe it in chat and the LLM asks you four questions that all amount to "show me what you're seeing."
Live demo
Open the dropdown, then scroll the page (mousewheel or trackpad). The dropdown closes itself. The bug: a window scroll listener dismisses the menu — even when the user didn't click outside it.
What to do: Use the Quick preset (5s, 10 frames). Click the button to open the dropdown, then scroll. Copy as Grid once the recording stops.
Prompt
"This dropdown closes itself when I scroll the page. Here are 10 frames from the moment I open it to the moment it disappears. What's most likely triggering the close — focus loss, a click-outside handler, or something in the scroll listener?"
02
A layout glitch that's gone before you can screenshot it
When the modal opens, the page underneath jumps a few pixels sideways for one frame, then settles. You can feel it but you can't catch it. A still image won't show the jump; only the sequence does.
Live demo
Open and close the modal a few times. Watch the right edge of the page — the content shifts when the body scrollbar disappears and reappears. The bug: setting overflow: hidden on <body> without compensating for the scrollbar width.
What to do: Use the Standard preset (10s, 1 fps). Trigger the modal, close it, trigger it again. The frame grid catches each "before / mid-jump / after" trio.
Prompt
"When this modal opens, the underlying page shifts for a split second. Frames 3–5 show the shift cleanly. Is this a scrollbar reflow, a paint-containment issue, or something with how I'm locking body scroll?"
03
A flash of error text that disappears before you can read it
You click Save, a red toast appears and dismisses itself in under a second, and you're left with no way to copy the message. You can read three words and a code. The LLM can't help if you can't tell it the message.
Live demo
Click Save. The error toast appears in the top-right of the screen and dismisses in 400 ms. Try to read it — you can't, not reliably. That's the whole point.
What to do: Use the Quick preset (5s, 2 fps). Click Save right after Start Recording. At least one frame will catch the toast mid-display so the model can read the error code.
Prompt
"An error toast flashes for under half a second when I hit Save. Frame 4 catches the message clearly. What does that error code mean, and what's the most likely cause given that I just edited a field and clicked Save?"
04
"How do I do this in this app?"
You're staring at an unfamiliar tool's settings panel trying to find one specific option. You don't know what it's called, the menus are nested three deep, and the docs are useless. You just want someone (or something) to look at the screen and tell you where to click.

The keyboard shortcuts are hidden inside Advanced → Inputs → Keyboard shortcuts. Walk through the tabs slowly while recording so the frame grid reads like a wayfinding map.
What to do: Use the Slow preset (20s, 0.5 fps). Click through General → Preferences → Advanced → Display → Inputs → Keyboard shortcuts. Each frame captures a different panel.
Prompt
"I'm in this app's settings and I want to set a custom keyboard shortcut, but I can't find where. Frames 1–3 are the main settings, 4–6 the Preferences sub-menu, 7–10 the Advanced tab. Which one of these is the closest, and is there one I missed?"
05
A multi-step user flow you want critiqued
You want a second opinion on your signup or checkout flow. Recording a video and pasting a Loom link doesn't help — the model can't watch it. But a 10-frame grid of the whole flow (cart → email → payment → confirmation) gives the LLM the entire sequence to react to in one shot.

Thanks for your support!
This is a demo. No card was charged.
Walk through the steps at a deliberate pace while recording. The final grid reads like a storyboard you can paste into an LLM and ask "where's the friction?"
What to do: Use the Slow preset (20s, 0.5 fps). Complete the flow at a steady tempo. Copy as Grid when capture stops.
Prompt
"Here's our checkout in 10 frames: cart → email → payment → confirmation. Pretend you're a first-time buyer. What's the single biggest friction point you see, and which frame shows it?"
