Adobe animate won't export my full video

Hey! I'm having the same problem … only the file I export is always corrupt in the sense that the beginning of the animation works up to a specific point when it just freezes. Everytime I reexport or export just the end to make amends for the "missing" part of the video, there's still a random amount of animation that just doesn't render. (I can tell because the file sizes vary even when exporting the exact same thing.) Why?? My settings are all default, the canvas is regular UHD. Even when I check the SWF movie, the whole video plays. I've been searching up and down the internet for a solution – can someone help me??

File > export > export video / media > frame range > Sellect the last frame range or just scroll untill u cant anymore , make sure the vido format is H264 and then hit export , your video will be exported fully and on mp4 format. 

Export to media encoder.

i had the same problem once and was only that i used shape tween on the main scene ( ether transform any shape tween into frame by frame, or replace it with motion tween)

some times its the simple stufff
to make soure this is the problem (youll find the render stops at the frame the shape tween does)
it doesnt happen to all shape tween , usually to an object you breaked apart then shaped tweened it.

I know this is a bit late as a response, but I faced the same problem and couldn't find any answers that actually addressed the problem. I will share what worked for me here so that anyone else searching for a solution in the future may benefit:

I had a simple 13 second scene and for some reason only 8 seconds would export, rrgardless of how I tried to export/preview it. I decided to see what was the "change" at 8 seconds that messed up the programme. What I found was that i had a very large image (way beyond the frame) which I only needed a small part of that I had pasted, and that image was being zoomed out of. When I deleted the image and inserted a smaller sized item, the scene exported to the end. I'm not quite sure why the programme 'can't handle' a big image, but doing what I described above sorted out the problem.

So to summarise: go to the point at which the export cuts and try to work out what has changed that has 'messed up' the porgramme. For me, it was image size. 

I'm no expert, but I hope that helps
