I don't know if its the latest update, but I'm getting serious lag when trying to playback the timeline in Premiere Pro. Using the 4k dji video files straight off the card. I have a moderately high end Core i7 6700k, 32GB ram, GTX 970. Premiere quickly uses over 20GB of RAM and I get a windows running out of memory error. I was going to increase my RAM to 64GB. Any suggestions for lag when editing dji files? I was also going to try putting all the video files on the 850 Pro SSD just while editing. Should I convert the files prior to editing using Adobe Media Converter - If so, what file format/codec would work well?
