Looping a video means repeating the same clip multiple times in a single file. Instead of relying on a media player's repeat button, you create an actual file where the clip plays two, three, five, or ten times in sequence. The result is a self-contained video that repeats on any player, platform, or device without needing special loop settings.
Why loop a video into a file?
Social media platforms do not always support looping. If you upload a 5-second clip to some platforms, it plays once and stops. By looping it into a 20-second or 30-second file, the content repeats naturally within the platform's player.
Background videos for presentations, events, or digital signage need to run continuously. A looped file ensures seamless playback without requiring the display system to handle repeat logic.
Music practice and dance rehearsal videos benefit from looping so the performer can watch the same move repeatedly without reaching for the replay button.
Product demos and animation showcases look more polished when the loop is baked into the file, especially for portfolio sites and trade show displays.
How many loops should you use?
For social media, 3 to 5 loops of a short clip (3 to 5 seconds each) creates a file that is 9 to 25 seconds long. This hits the sweet spot for watch time without feeling repetitive to a viewer who watches it once through.
For digital signage and background displays, 5 to 10 loops create a longer file that plays for several minutes. The loop count depends on how long the display runs before the file restarts from the beginning.
For practice and rehearsal, 5 to 10 loops is typical. Enough repetitions to study the movement without restarting, short enough to re-upload quickly with a different clip.
File size grows linearly
A 3-loop video is roughly 3 times the file size of the original. A 10-loop video is roughly 10 times the original. For very short clips this is fine, but for longer clips the file can get large quickly. If your source is a 30-second clip at 50MB, a 10-loop version is approximately 500MB.
For large loops, consider compressing the source clip first using the MediaBrew compress tool, then looping the smaller version.
How to loop a video in your browser
The MediaBrew loop tool lets you upload any video and choose how many times to repeat it (2 to 10). The tool concatenates the clip the specified number of times and produces a single MP4 output. Processing runs locally in your browser using FFmpeg WebAssembly. No upload, no account, no watermark.
