PNG format video with less File size

Hi,

I have a video of about 10 seconds.

It's a basic Walk cycle done using DUIK Bassel. Once i try to export it using -AVI> RGB+Alpha format, the file size is about 40.9 GB.

I need a PNG Format video with less size and high quality. Can anyone please help. Is there any other way to get the PNG video format style ?

Here are the specifications I Used :

FPS : 99 FPS

Quality : HIGH

Time : 10 seconds

I even tried Wire frame, half resolution but the size isn't reducing so well. There's just a 1-2 GB difference.

Please help me.
