This looks to be some great editing software (and free) and I have noted a few instances that people are using this software over GPS, Premiere and FCP X. For those with experience with the software, how are you editing GoPro 4K footage. Importing 4K footage and trying to edit, results in choppy playback. Resolve 12 will handle Apple Prores but I don't have the program or the codec. Is it advisable to convert gopro mp4 files before editing and if so, what to and with what software. I'd really like to use this software but could use some help on workflow.
