> There is no time limit, but there is a practical one — and it is about memory.

Nothing in this recorder imposes a time limit. The real constraint is your computer’s memory, because the file is held there until you download it.

## What actually limits it

Recorded data accumulates in the browser tab. A 1080p recording produces very roughly 500 MB per hour; a 4K one, several times that. When the tab runs out of memory, recording stops.

## A practical guide

Up to about thirty minutes is comfortable on most machines. Beyond an hour, record in segments — not because it will definitely fail, but because losing a two-hour recording is a bad afternoon.

## What to do for very long recordings

Use a desktop recorder that writes to disk as it goes, or record without installing anything in shorter takes. That is the one thing a web page fundamentally cannot do.

OBS Studio is the usual choice and is free on every platform. Your operating system’s built-in recorder also writes straight to disk, which is why it can record for hours without trouble.
