Is there any way to make an animation with more than 16,000 frames?

I have the same problem

html5 can be unlimited in length.

But if you output the video,The same limit is 16,000 frames.

Therefore, I am using the HTML5 format as the primary format.

If I'm going to do a long animation, I'll need to make it in a new scene.

Window --- scene-----Add a new scene.

But the sad thing is that HTML5 doesn't even have scene addition.

It is actually a per-timeline limit.

If your intended output is video, I would suggest you just split your project into multiple FLAs and then combine the exported videos in Premiere.

A way to have a longer FLA is to wrap 16,000 frames into Movie Clips. Each Movie Clip occupies only one frame on the Main Timeline. In theory you can have 16,000 Movie Clips with 16,000 frames inside each of them.

At the end of each MC's timeline you tell it to go to play the next frame on the main Timeline.

If you want to export this to video you will have to choose the 'Time' option in export video dialog and input the calculated duration of your entire project.

Personally, I would use this convoluted method only if I absolutely have to, because of some project specifics.
