Timeouts with Pexels videos

When including videos from Pexels, especially when rendering on Remotion Lambda, you may encounter the following error:

A delayRender() 'Loading <Html5Video> duration with src="https://videos.pexels.com/video-files/5182920/5182920-hd_720_1280_25fps.mp4"' was called but not cleared after 28000ms.

or

A delayRender() "Loading <Img> with src=http://localhost:3000/proxy?src=https://videos.pexels.com/video-files/5182920/5182920-hd_720_1280_25fps.mp4" was called but not cleared after 28000ms. See https://remotion.dev/docs/timeout for help

Problem

Pexels throttles (artificially slows down network speed) videos when they are requested often.
Since each of the many Lambda functions spawned loads the video, it leads to a lot of requests in a short amount of time.

These timeouts are not a problem from Remotion's side.

Solution

Instead of using direct links from services like Pexels, download and re-host the videos on your own servers, or in a S3 bucket.
