What is the frame limit in adobe animate?

bro its been more then a minute

The amount of media that would go into 2 hours of animation could lead to other issues. You might want to have one "movie scene" per FLA, then combine them in a video editor.

But, if there is a reason to have it be one animation in one FLA, you can use this approach (make sure you are working in an ActionScript 3.0 FLA):

Put an empty MovieClip into frame 1. Go into the MovieClip and make your first 16000 frames of the animation. It need not be exactly that amount, you would most likely end the animation at a sensible point.

Put another MovieClip into frame 2 of the main timeline. Go into that one and make another 16000 frames of animation.

For 172k frames you would only need 11 MovieClips like that, taking up frames 1 to 11 of the main timeline, and each one has up to 16000 frames in it.

Make the last frame of each MovieClip's timeline have a keyframe in one layer. Select that keyframe and in the Actions panel put this script:

MovieClip(this.parent).gotoAndStop(MovieClip(this.parent).currentFrame+1);

In the first frame of the main timeline, put stop(); into the Actions panel, so that it doesn't run through the 11 frames right away. Also put stop(); in a keyframe in the last frame of the last MovieClip, instead of the other script that would make it jump on to the next frame in the main timeline.

That should then animate through all 11 MovieClips, one after the other, and will take as long as all of the frames combined.

To export that to video, use the time values in the export dialog, not the frame ones. For example, this would export video that was 1 hour 58 minutes and 45 seconds long:

oh really? that's fantastic! thats more than enough thank you very much X3
