I shoot vertical video and import clips straight from my camera,

Clips are always shot in landscape on my camera so I flip all 90 degrees in the edit tab

When masking my grade , the masks take irregular shapes

It's also near impossible for me to transform and compound every single clip that I work on, as I colorgrade the timeline not single clips

Please advise of any tips or any external tools can help me flip videos with no quality loss
