a video from imovie to my iPad Pro makes it lower quality?

[RawRock]

These videos Im making with my Mavic Pro 2 will look amazing on imovie when im done, but just by saving it to my videos on my ipad pro makes the quality jump way down. How can I fix this problem?

Confirm your exporting the SDCard file (Full quality) video clip and not using downlinked copy (Lower Res)?
