I add another photo, i hope it good.What export settings did you use?
Your attached screenshot is too small right now to get any information from it. You can attach a screenshot in its original resolution.
And how long is the sequence you want to export and is it HD?
I will add a photos if its okOkay, H.264 is highly compressive, thus it should be less than 1 GB. Where do you get the "200 GB" from?
Can you describe your workflow in more detail or attach more screenshots, if you are unsure?
