Why Is My Video Not Loading on loopvid?

Updated

loopvid itself names three likely causes when a video fails to load: your browser does not support the video type, the link you were given is broken, or the video is temporarily unavailable. The page also lists the direct links it tried, which is the fastest way to tell which of the three you are dealing with.

What loopvid does with your video

loopvid takes a hotlink to a video file and plays it in a loop. According to the site, videos submitted through the form are handled entirely by your browser via JavaScript — the server only sees a request for the front page, so the file itself is not uploaded or processed server-side. That privacy note applies to the front page only, not to requests made to their blog.

Because playback happens in your browser, most loading failures come from the browser or the source file, not from loopvid's servers.

Check the direct links first

When a video won't load, loopvid displays the direct links it attempted. Open one of those links in a new tab:

  • It plays there → the file and link are fine, so the problem is browser-side (codec or format support).
  • It 404s, 403s, or shows an error page → the link is broken, expired, or access-restricted. Get a fresh direct link to the file.
  • It hangs or times out → the source is temporarily unavailable. Wait and retry, or use a different host.

This one step separates "bad link" from "bad browser" without guessing.

Match the format to your browser

loopvid plays whatever video file you point it at, so support depends on your browser's built-in decoders, not on loopvid. Common trouble spots:

Symptom Likely cause What to try
Nothing renders, console shows a decode error Container or codec the browser can't decode (e.g. some MKV or HEVC files) Convert to MP4/H.264 or WebM, then re-link
Audio plays, video doesn't (or vice versa) Codec supported for one track but not the other Re-encode both tracks into a widely supported format
Plays in one browser, not another Browser-specific codec support Try a browser known to handle that format

If you need to convert, the loopvid page points to gfycat for GIF-to-video, imgflip for video-to-GIF, and offers a tutorial for making your own clips with Avidemux or VirtualDub. For looping YouTube videos specifically, it directs you to endlessvideo instead.

Confirm the link is actually a direct file link

loopvid expects a hotlink to a video file — a URL that ends in the file itself, not a page that embeds it. A YouTube watch page, a streaming-site viewer page, or a download page with a redirect will not work as a source. If the direct links loopvid lists point at an HTML page rather than a media file, that is your problem: find the underlying file URL.

Quick checklist

  1. Open one of the direct links loopvid lists.
  2. If it fails there too, replace the link with a working direct file URL.
  3. If it works there but not in loopvid, convert the file to MP4/H.264 or WebM.
  4. If it still fails, try a different browser.
  5. If the source is simply down, retry later.

If you want to avoid this entirely

The most reliable setup is a direct link to an MP4 (H.264 + AAC) or WebM file hosted somewhere stable. Those formats are broadly supported, and a stable host removes the "temporarily unavailable" case. loopvid is free software and its source code is downloadable from the site if you want to check how playback is implemented.
