I went to got shoot at a lake with my Mavic pro platinum but I didn’t have my SD card in the drone. The footage has saved on my dji go app but is there a way I can access it in 2.7k or is it restricted to the preview only, since I had no sd card installed

I'm wondering how this functions as well. If I insert an SD-card, will I get two copies of each film/picture? One low-res in the phone and one high-res on the SD-card?
