"I've got some DJI Osmo Action 4 4K files that I'd like to use on Premiere Pro and I was wondering how I can get them on there. At the moment they aren't able to import in to my projects or events. Do I need to convert them to be able to use them? If so what file do they need to be converted to and what can I use to convert them?"
Acutely, Final Cut Pro and Premiere Pro generally can recognize MP4 files. However, you may have the painful experience importing DJI Osmo Action 4 H.265 Mp4 files to Final Cut Pro/Premiere Pro, or even DJI Osmo Action 4 footage can't be accepted by Final Cut Pro/Premiere Pro. Actually, if your Osmo Action 4 files are muxed H.265 videos, many editing software won't accept them because of the codec incompatibility.
