continuous looping

[nancyw51428426]

I would like my animation .mp4 video to continuously loop. All symbols are graphics. I exported this as video (.mp4) In the Publish Settings "Loop Timeline" is checked but the mp4 does not loop. It is an HTML5 Canvas Document.  Would love to know how to fix this.

Once exported to MP4, there's no native "loop" option from within Animate that will force whatever video player on your machine to loop it. You'll have to go to playback settings for whatever player you are using to set it to "Loop" if that option exists. It would probably have to be selected everytime the MP4 is opened inside your desired player unless there's an option to make it the default.

Thanks for this information. I'm curious though what is the purpose of the Publish Settings "Loop Timeline".  If within animate 2022 could I apply an action script?  Do you know if there is a setting in Adobe Premiere to loop video?

Where in Publish Settings do you see "Loop Timeline"? 
Publish Settings doesn't offer export to video/MP4. So I assume you are referring to Export Settings correct? But Video/Movie export settings don't offer "Loop Timeline" either.

Video format, such as MOV, MP4, etc, relies on video players to play back the file. Those players, most often provide the option to loop the file. It's then up to you, the user, to select it or not. But there's no code that can be written that gets baked into rendered frame-based sequence that can be executed during playback. That would mean a whole bunch of security issues surrounding video playback for decades. 
You simply can't export a video file and have it force loop across all media playback devices on every computer for every user. If you google it, you'll find a universe of "No, you can't" with the only options to be just what I described...

"To make your video loop in QuickTime (available for Mac or PC), first download your video as a MP4 file to your computer's hard drive. Open the file with Quicktime and in the menu, choose View, and then Loop. When your video is finished playing, it will automatically begin again."
