Photoshop Video Render

Hello,

I made a video montage of differente clips on photoshop cc 2017, applied some layers and few modification. but rendering is impossible in an mp4 ipad compatible format - as it creates a file of over 50 GB if not more. im always forced to cancel the render.

in total the video is 2.2 h long, i understand photoshop may not be the most suitable program for this but now the hours of work have been put in and given my limited skill i'd love for there to be a solution using the project ive created: rendering smaller section does work but in full not

​I've also tried importing the project in Premier without success.

​could you be of any help?

very beginner but eager to understand

​Regards

​Boris
