Can you loop a video in Google Slides?
Not with a setting. Slides only chooses how a video starts. Make the video longer before inserting it, by repeating it to 10 minutes or an hour, and set it to Play (automatically).

Slides can start a video by itself but can’t repeat it. Put the repeats inside the file instead, then loop the slideshow if the whole deck should run on its own.
Google Slides can’t loop a video: the Video playback options only choose how a video starts, and it stops at the end. The workaround is to make the video long enough before you insert it, for example repeating a 15-second clip to ten minutes, and set it to Play (automatically). To the audience it looks like a loop.
The looper on this page makes that file in your browser. Leave Repeat on Length at 10 min, or pick 1 hour for a screen at an event, and export an MP4. Then upload it to Google Drive and insert it from there. Steps for both halves are below, along with how to loop the entire presentation and when a GIF is the simpler answer.
Open the clip in the tool above. Repeat is set to Length at 10 min; pick 30 min or 1 hour if the slide stays up longer. Press Find the best loop for a clean join, then Export video and Download video.
Slides inserts videos from Google Drive or YouTube, not straight from your computer. Upload the MP4 to Drive first, in the same account you use for Slides.
In Slides, choose Insert → Video, open the Google Drive tab, select the file and press Insert. Resize it on the slide as you like.
With the video selected, open Format options and expand Video playback. Choose Play (automatically). Tick Mute audio for a silent background.
Press Slideshow and let the video run past the original clip’s end. It carries on, because the repeats are in the file.
PowerPoint has a Loop until Stopped checkbox; Google Slides has nothing equivalent. Its Video playback panel offers three ways to start a video, Play (on click), Play (automatically) and Play (manual), plus Start at and End at times and Mute audio. When the video reaches its end, it stops on its last frame.
That is why the reliable answers all change the video rather than the slide. A file that already contains the repeats needs no player setting at all, and behaves the same in the editor, in presenter view, in a published deck and on someone else’s computer.
If the deck should run round and round on its own, Slides can do that part. There are two ways:
Auto-advance moves on after the set time whether a video has finished or not. Give the video slide a timing at least as long as the part you want seen, or make the looping file match the slide timing so it never visibly ends.
For a short, silent animation, there is a simpler route: Slides treats a GIF as an image, and GIFs repeat on their own. Make one with the MP4 to GIF converter (or switch Format to GIF in the tool above), then insert it with Insert → Image → Upload from computer. It loops in the editor and in the slideshow, with no Drive upload and no playback settings.
Keep GIFs short and narrow, a few seconds at 480 to 800 pixels wide, so the deck stays quick to open. For anything with sound or longer than about ten seconds, the looping MP4 is the better choice.
Slides can insert a YouTube video by search or By URL, with the same Video playback options and no loop. YouTube’s own loop setting, described in how to loop a YouTube video, doesn’t carry over into Slides. If the video is yours, loop your original file here and insert the result from Drive; if it isn’t, the YouTube video looper repeats it in a browser window, outside Slides.
Looping in other presentation software works differently: PowerPoint has a built-in option, covered in looping a video in PowerPoint.
Not with a setting. Slides only chooses how a video starts. Make the video longer before inserting it, by repeating it to 10 minutes or an hour, and set it to Play (automatically).
Select the video, open Format options, expand Video playback and choose Play (automatically). It starts as soon as the slide appears in the slideshow.
In the slideshow, open ⋮ → Auto-play, choose a timing, tick Loop and press Play. For a published deck, tick Restart the slideshow after the last slide in Publish to web.
Slides takes videos from Google Drive or YouTube. Upload the file to Drive first, then use Insert → Video → Google Drive.
Yes. Inserted as an image, a GIF plays on its own and repeats according to its loop setting, which is forever for most GIFs.
The video streams from Drive, so the deck itself stays light, but a large file can take a moment to start. A short loop at 720p keeps even an hour-long file reasonable.
