jumbo file size export

newbie here - imported 148mb mp4 video (40 min presentation)

removed two 3 second bloopers - read instructions - export

1080 high = 628mb

720 high = 624mb

720 medium = 491mb

was expecting roughly the same 148mb - no can do 500mb for single video.

ruins user experience!

used up 3 trial plan exports - why would i want more?

lousy first impressions...comments invited

how to plan?
