My animated intro for my game is too heavy?

I've created a platform game, and I want the first screen that shows to be an animated intro to the game that I created in Flash and exported as pngs (in pretty low quality)

I've exported the game and it works when I make a different layer be the first to show, but when I make the intro layer be first, or try to reach the intro through the menu I made, the app crashes.

This happens when I export it as HTML 5 and as Node - Webkit.

Any idea how I can make the intro weigh less without losing any more quality?

(the animation is around 400 frames long)

Try the video plugin, or do the cutscenes in your game's engine

fassFlash How do I do that?

It would have probably been better to create the intro in Construct2.

I dont know how big the png's are pixel-width times pixel-height, but that times 4 times 400 is how much VRAM-bytes it will use, and I guess that's the issue. Animations made with flash can almost certainly be recreated inside Construct2, albeit sometimes in a different manner.

yes either you record your Intro as video or remake it in C2
